koma39.com is the personal official website of the Japanese blogger “こまちょふ.” Its title highlights that the author has earned over 20 million yen in total through blogging. The site is not primarily a tool-based product; instead, it is a content blog focused on topics such as housewives, side hustles, making money from blogs, and affiliate marketing. It is therefore best categorized as a marketing / affiliate-marketing content site.
The website mainly offers articles to read, covering topics such as whether 楽天アフィリエイト can make money, how to stay motivated with trend blogging, how to find affiliate offers that are easier to convert, and how to improve conversion rates. From the crawled article content, the author uses scenarios such as broken washing machines, TV shopping, and family life to explain product-selection logic like “urgency,” “low purchase barriers,” and “avoiding YMYL.” There are also case studies analyzing the relationship between blog revenue and knowledge of ASPs.
The currently crawled content does not show any clear pricing for paid courses, memberships, or consulting services. Public articles appear to be freely accessible. The site navigation includes entries such as “お問い合わせ” and “ブログを始める！”, which may lead to inquiries or recommended resources, but this is not enough to determine a specific monetization or pricing model.
The main strengths are its clear positioning and easy-to-understand language, making it suitable for people who are new to Japanese blogging, side-hustle writing, or affiliate marketing and want to quickly build a basic understanding. The articles incorporate personal experience, making them lighter and easier to read than official tutorials. The drawbacks are also obvious: it feels more like a collection of personal experiences than a structured course; some articles date back to around 2020–2021, so affiliate platform rules, the SEO environment, and ad rates may have changed; and the content is highly focused on the Japanese market, so Chinese users can mainly treat it as a source of ideas.
It is suitable for Japanese-speaking individual site owners, housewives exploring side hustles, content entrepreneurs, and beginners who want to study Japan’s affiliate marketing ecosystem or understand how blogs monetize through ASPs and e-commerce affiliate programs. It is not suitable for business users who need automated marketing tools, advertising platforms, or rigorous data reports.
As a regular Japanese personal blog, the site can usually be accessed directly. However, page speed may be affected by overseas hosting, image resources, and local network conditions. The content is in Japanese, with no Chinese interface.
