The 2025 Guide to Choosing a CMS for Small Businesses: A Deep Dive into 5 Top Options

Published: 2024年11月20日

In recent years, in addition to the traditional WordPress, a large number of headless CMSs—where the front end is decoupled—have appeared and are drawing attention for website operations.
anken-hyouban.com
This article compares five representative CMSs (Sanity, Strapi, WordPress, Contentful, microCMS) with a focus on adoption by Japanese small and medium-sized businesses, using the evaluation criteria below. Understand the characteristics of each CMS and use them as a reference to choose what fits your company.

  • Learning cost & ease of use (can non-engineers handle it?)
  • Japanese support (admin UI, documentation, support)
  • Functionality (preview, versioning, media management, workflows, etc.)
  • Flexibility & extensibility (freedom of API design, custom fields, etc.)
  • Performance (response speed, caching, etc.)
  • Community & ecosystem (number of users, support structure, plugin richness)
  • Pricing (free tiers, plans, usage-based models)
  • Differences between self-hosted and cloud (deployment/maintenance cost, security, required infra knowledge)
  • Multilingual support & translation workflow (managing multilingual articles, translation assistance, implementation ease)

Learning Cost & Ease of Use

Because microCMS is domestically developed, its admin UI is intuitive with strong no-code operations, enabling even non-engineers to update content intuitively.
anken-hyouban.com
It even claims to “cut updates that take five days down to one hour,” making it beginner-friendly by design.
anken-hyouban.com
WordPress, boasting the world’s No.1 CMS share, is familiar to many and its admin UI is relatively easy to understand.
omomuki-tech.com
Especially for blog posts and basic site updates, even non-engineers can handle it, so the learning cost is low.

Strapi lowers the initial hurdle because you can set content models from the admin UI, but installation and advanced customization require development knowledge.
omomuki-tech.com
Plugin development and fine-grained extensions require Node.js/React knowledge, which imposes a certain learning cost.
omomuki-tech.com
Sanity skews developer-oriented: you need programming skills to define schemas and learn its unique query language (GROQ).
omomuki-tech.com
While that brings high freedom, it’s not ideal for operations led mainly by non-engineers. Contentful lets you define content models in a GUI, but the UI is in English and uses some specialized terminology, so technical involvement is desirable at the outset. The free plan is limited to evaluation and cannot be used commercially, which raises the bar for small-scale use.
qiita.com
In short, if you’ll operate without engineers, WordPress or microCMS are candidates, while Strapi, Sanity, and Contentful require technical support for initial setup.

Japanese Support

In the Japanese market, Japanese-language support directly impacts usability. As a “domestically produced headless CMS,” microCMS offers full Japanese coverage for admin UI, docs, and support.
anken-hyouban.com
Amid many overseas headless CMSs lacking Japanese, microCMS is praised for enabling comfortable use in Japanese environments.
anken-hyouban.com
WordPress also has extensive community translations, and its official site and forums support Japanese. In fact, WordPress holds an overwhelming 82.8% share among CMSs for Japanese websites, and the domestic user community is very active.
hubspot.100inc.co.jp
In terms of abundant Japanese-language resources and support, WordPress and microCMS stand out.

By contrast, Contentful and Sanity provide admin UI and documentation only in English, with essentially no Japanese support.
qiita.com
Strapi’s admin UI is also English by default, though partial Japanese localization is possible via community plugins
scr.marketing-wizard.biz
(though not complete). On the community front, Strapi is centered on the English-speaking world, so Japanese information is limited. Overall, if you prioritize comfort in a Japanese environment, microCMS is the strongest candidate, and WordPress also makes it easy to obtain information domestically.

Conversely, when using Contentful or Sanity, note that operating in English and handling inquiries in English will be required.

Functionality

CMSs differ in their content management features. Being traditional, WordPress has all the basics for blogs: draft/publish, preview, revision history, media (image) management, scheduled publishing, etc. Add plugins to easily extend features like contact forms and SEO settings. microCMS, while headless, provides draft saving and secure previews, scheduled publishing at specified times, and pre-publish approval flows.
jitera.com
Indeed, microCMS offers convenient features like “scheduled publishing” at a specified time and per-member view permissions, covering everything you need.
jitera.com
jitera.com
It also has robust media management, such as automatic image resizing via API.
jitera.com

Contentful, befitting the enterprise market, is feature-rich. In addition to Markdown-capable rich text and automatic image resizing, it offers fine-grained permission control and workflow features that let administrators govern the publishing process.
jitera.com
Teams can complete content creation and approvals entirely within Contentful, which is reassuring for large projects.
jitera.com
Sanity excels at collaboration features such as real-time co-editing and change histories, enabling multiple people to edit content simultaneously.
qiita.com
Major changes can be reviewed by tracing history, making it suitable for team development.
qiita.com
Sanity also lets you implement powerful custom editors in code and add custom input widgets. Strapi includes a simple “draft & publish” status management by default and lets you build preview environments as needed. Content type definitions are flexible, supporting many field types—text, numbers, dates, rich text, media, and relations to other content.
omomuki-tech.com
It also offers Role-Based Access Control (RBAC) to fine-tune user permissions; even the free community edition supports basic permission management.
omomuki-tech.com
However, Strapi lacks advanced features like content change history and approval workflows out of the box; you’ll supplement them with plugin development or paid editions if needed.

Flexibility & Extensibility

Strapi and Sanity are especially known for high flexibility. Strapi is open source, so you can modify its source code, and its plugin system makes feature additions easy.
omomuki-tech.com
It auto-generates REST APIs by default and can support GraphQL via a plugin, allowing implementation tailored to your frontend stack.
omomuki-tech.com
Developers can customize API endpoint behavior and the admin UI, providing extremely high freedom in data structures.
omomuki-tech.com
Sanity defines content schemas and input forms in JavaScript, enabling flexible custom fields and validations. Besides its unique GROQ query language, it also provides an official GraphQL endpoint—offering high freedom in API design. The editorial “Sanity Studio” is OSS and fully extensible; you can add plugins and custom input components to redesign the editor UI.

WordPress also boasts top-class extensibility via plugins and themes. With thousands of official plugins, you can add features from e-commerce to social integration, and custom post types/fields let you model proprietary data structures. It ships with a REST API and lets you implement custom endpoints in PHP when needed. However, WordPress wasn’t originally designed for headless use, so its flexibility and performance for API-driven data retrieval can lag behind headless-native CMSs.
omomuki-tech.com
If you handle complex data structures, a native headless CMS like Strapi usually provides greater freedom.
omomuki-tech.com
Because Contentful and microCMS are SaaS, you can’t extend the backend itself, but they’re flexible within content-model design. Contentful supports diverse field types—relations (reference to other entries), rich text, JSON fields, etc.—letting you model complex content. microCMS offers a full set—text, images, rich editors, repeatable fields, etc.—so you can build fairly sophisticated data structures with no code.
cly7796.net
It also has an extension field feature to embed custom input fields integrated with external data—for example, selecting information from an internal database directly in the admin UI.
document.microcms.io
zenn.dev
That said, microCMS does not allow programmable server-side processing, so special business logic must be implemented on the frontend or via external services.

Performance

When selecting a CMS, distribution speed and scalability matter. microCMS includes a CDN in its content API and achieves very fast responses—averaging in the 1-ms range on cache hits.
techgym.jp
For small to medium sites, the free tier includes up to 20 GB/month of data transfer, and pairing it with static site generators (e.g., Next.js or Astro) makes load distribution easier.
scr.marketing-wizard.biz
scr.marketing-wizard.biz
Contentful runs on globally distributed infrastructure, providing fast and stable content delivery via API. Large media assets are cached/optimized on Contentful’s side, and its design withstands enterprise-level high traffic. Sanity emphasizes real-time capabilities and optimizes its backend on a proprietary cloud; it also scales for heavy traffic, with up to 1 million requests/month free via CDN.
qiita.com

For Strapi and WordPress in self-hosted setups, performance depends on server specs and architecture. WordPress is dynamic, so page caching (staticization) is virtually essential under high load. With proper caching and tuning, large sites are feasible, but out of the box, response times tend to be slower than headless CMSs under comparable traffic.
omomuki-tech.com
Strapi, built on Node.js, runs briskly, but handling DB load and concurrency falls to your architecture. Still, Strapi imposes no limits on requests or storage when self-hosted, and you can scale horizontally as needed.
qiita.com
If offered as a managed cloud service, vendors may bundle auto-scaling and CDN (e.g., Strapi Cloud, WordPress.com). Overall, SaaS offerings (Contentful, microCMS, Sanity) deliver strong performance without tuning, while self-managed Strapi/WordPress can reach high performance with the right configurations.

Community & Ecosystem

Adoption and support structures are crucial. WordPress dominates Japan’s CMS market with over 80% share,
hubspot.100inc.co.jp
leading in user base and volume of information. Official forums, books, and blogs abound, making it easy to find Japanese-language solutions. The developer community is huge as well, with 50,000+ plugins and countless themes available,
omomuki-tech.com
which means very wide options for function and design extensions. For SMEs, it’s easier to find WordPress-savvy talent and creators, so you’re advantaged in know-how and staffing.

Since launching in 2019, microCMS has steadily grown its domestic user base. As a pioneer of Japanese headless CMS, it has adoption cases at well-known services like ZOZOTOWN and CrowdWorks,
anken-hyouban.com
and it’s spreading especially among corporate sites and owned media for Japanese companies. Official docs are substantial and support responses are quick, lending reliability. Community-driven knowledge sharing is getting active across Qiita and blogs. In its ecosystem, microCMS provides an SDK for extension fields, and volunteers are starting to offer handy OSS extensions.
document.microcms.io
zenn.dev
While the plugin count doesn’t match WordPress, improvements aligned with domestic needs are ongoing.

Globally popular as OSS, Strapi has amassed 50k+ GitHub stars and enjoys active community development.
omomuki-tech.com
omomuki-tech.com
You’re likely to get answers via forums and Discord, and OSS characteristics enable prompt updates and information sharing when issues arise.
omomuki-tech.com
Official and community plugins are increasing, useful for features like auth and search. Reported adopters include major global companies such as IBM and Walmart,
omomuki-tech.com
which inspires confidence in reliability and track record. In Japan, however, the Strapi community is still small, and Japanese-language information is limited, so you’ll rely on English resources.

Contentful, being commercial, lacks an OSS-style community, but its official support is robust. With many global adopters, blogs and docs are plentiful. In Japan it’s less widely known, but some large enterprises choose it for multilingual and large-scale operations.
qiita.com
Developer SDKs and samples are well prepared, and many questions can be resolved via English-language Q&A sites. Sanity, as a developer-first service, has strong support from engineers. Its official Slack community and forums are active, with frequent discussions, feature proposals, and plugin sharing. Domestic case studies are only beginning to grow, but with capital participation from global companies (large fundraising in 2022), its ecosystem is expected to expand.

Pricing

Pricing matters for SMEs. WordPress itself is open source and free. If you install it on your own server, there’s no license fee, though you’ll pay for hosting and domains. For small sites, low-cost shared hosting (a few hundred yen per month) suffices, making the cost barrier very low. Many plugins are free or one-time purchases, enabling adequate builds even on tight budgets. Managed hosting like WordPress.com runs from a few hundred to a few thousand yen per month—reasonable as an operations fee.

microCMS is offered as a cloud service, and even its free tier allows commercial use.
qiita.com
The free plan permits up to 10,000 content items, 20 GB/month API transfer, and three admin users, so you can start small to medium sites without cost.
qiita.com
The paid Team plan starts at ¥4,900/month, which is relatively affordable: transfer limits rise to 200 GB/month, content items to 20,000, and the number of API schemas (content models) increases—ample for business use.
qiita.com
At higher tiers, the Business plan (around ¥60,000+/month) offers 1 TB/month transfer and more advanced features (permission management, IP allowlisting, custom statuses), supporting large-scale sites.
jitera.com
jitera.com
You can also raise limits with add-on fees, giving flexible, stepwise cost control.

Contentful’s free plan is limited to development/evaluation; commercial projects require a paid contract.
qiita.com
Even its cheapest paid plan (“Lite”) starts around $300/month, targeting organizations with larger budgets.
qiita.com
In return, you get enterprise-grade services such as unlimited users, multilingual/large-volume content support, and SLAs. Few SMEs adopt Contentful alone; some contract via agencies. Sanity’s free tier is very generous: up to 1M requests/month (via CDN) + 250k API requests, 100 GB storage, and 10,000 content items at no charge.
qiita.com
Beyond that, you scale with usage-based billing—well suited to starting small and growing gradually.
qiita.com
Paid plans begin around $99/month, adding team-oriented features such as role-based permissions and scheduled publishing.
qiita.com

With Strapi’s open-source edition, licensing is free with no limits.
qiita.com
Self-hosting means only server costs, making it ideal when you want to minimize initial expense.
qiita.com
Alternatively, the official “Strapi Cloud” starts from $15/month for easy onboarding.
qiita.com
The free Community Edition covers most needs, while the Enterprise Edition (paid) adds security/management features like audit logs and SSO.
omomuki-tech.com
For SMEs, a hybrid path works well: try the free OSS on your infra first, then move to the cloud edition as needed.

Self-Hosted vs. Cloud

As noted, there are clear differences between self-hosted (install on your own servers) and cloud (use the vendor’s hosted service). WordPress and Strapi are basically self-hosted (on-premises or on your own cloud account), but both have official hosting/managed options, giving users choices.
omomuki-tech.com
omomuki-tech.com
Benefits of self-hosting include data control and high customization freedom.
omomuki-tech.com
You can build environments aligned to your security policies and reduce vendor lock-in risks.
omomuki-tech.com
omomuki-tech.com
You can also finely control infra costs and optimize to your usage scale.
omomuki-tech.com
On the other hand, you must handle server setup/operations, security measures, and updates—requiring expertise and resources.
omomuki-tech.com
omomuki-tech.com
WordPress, being widely used, is frequently targeted for vulnerabilities; neglecting plugin management and regular updates raises security risks. Strapi also demands ongoing maintenance, such as compatibility adjustments during major upgrades.
scr.marketing-wizard.biz

Contentful, microCMS, and Sanity are basically cloud-only; the provider manages all infrastructure.
scr.marketing-wizard.biz
scr.marketing-wizard.biz
Cloud benefits include no infra management, easy initial adoption, automatic scaling, and immediate security patches.
omomuki-tech.com
Your team can focus on content and frontend development, with fewer worries about downtime or performance degradation. Downsides include the possibility that monthly fees accumulate to more than self-hosting,
omomuki-tech.com
customization limits due to vendor control, and being unable to directly remediate service outages. Still, leading cloud CMSs have robust track records and often offer SLAs. In short, choose cloud if you want to avoid infra overhead; choose self-hosted if you prioritize freedom and cost optimization.
omomuki-tech.com
For SMEs without server-ops skills in-house, cloud is the safer choice.

Multilingual Support & Translation Workflow

If you’re going global, managing content in multiple languages is key. Contentful’s strength is multilingual support: one entry can hold fields for multiple languages.
qiita.com
For example, you can keep Japanese and English translations under the same structure and switch languages easily. For large sites covering many languages, Contentful’s localization features and translation workflows are highly useful, and paid plans include dedicated support.
qiita.com
Strapi enables multilingual management via its official “Internationalization (i18n)” plugin.
omomuki-tech.com
You set supported languages per content type, create/manage variants of the same content in different languages, and request specific languages via API query parameters. While entries multiply by the number of languages, the admin UI lets you edit/switch by language, so it’s practical.

microCMS does not (yet) have as explicit multilingual features as Contentful, but there are workable approaches.
help.microcms.io
One is integrating an external translation service (e.g., WOVN.io) for automatic translation.
help.microcms.io
Another is preparing each language’s content on the microCMS side and registering translations manually.
help.microcms.io
For the latter, you can either split content models by language (“news_en,” “news_ja”) or keep multiple language fields within one record.
help.microcms.io
These take some effort, but for small two-language sites, they work fine—in fact, there are case studies of multilingual sites built with microCMS + Next.js.
blog.microcms.io
Since 2023, the microCMS admin UI can also be switched to English,
blog.microcms.io
making it easier when overseas staff are involved. Sanity lacks built-in multilingual features, but you can support them flexibly through schema design—linking language variants via cross-references or preparing language-specific field sets, as suggested by the community. Official best practices for multilingual management are published; if you don’t mind coding customizations, you can implement sophisticated localization. WordPress is single-language by default, but plugins widely enable multilingual operation. With popular plugins like “WPML” or “Polylang,” you can associate translations with posts/pages and easily add language switchers for visitors. Because it’s not official, setup requires care, but proven plugins keep the barrier manageable.

Summary

We compared five major CMSs with Japanese SMEs in mind. Each has different strengths, so no single winner fits all; here are some guidelines. If you prioritize Japanese-language support, microCMS is strong: it allows commercial use even on the free plan and its Japanese UI avoids confusion, easing adoption where technical staff are scarce.
qiita.com
If you have a healthy budget and need robust features, Contentful is a candidate—especially for multilingual or enterprise needs—with favorable ROI.
qiita.com
If you have in-house development resources and want to minimize initial costs, Strapi offers the greatest flexibility and cost efficiency.
qiita.com
You can start free with the OSS edition and try the cloud edition cheaply—but server management skills are required.
qiita.com
For teams seeking cutting-edge collaboration and extensibility, Sanity is attractive: its generous free tier lets you start small and scale gradually, and real-time editing supports team development.
qiita.com
WordPress remains a strong choice for “ease and all-around capability.” Because it’s all-in-one, you can go live as soon as you have a server, and plugins fill most gaps. For blog-centric, domestic sites, abundant skilled staff make it easy to get operations on track quickly.
omomuki-tech.com

For SMEs, the key is choosing a CMS that fits your organization and goals. If you want to “launch a company site quickly” and “let non-engineers handle updates,” WordPress or microCMS fit well. If you want to “deliver content to mobile apps or IoT” or “handle complex data structures/features,” Strapi or Sanity shine. It’s also wise to start with free plans and begin small.
qiita.com
As each service continues to revise pricing and enhance features, check the latest information and select the CMS that best fits your company.
