What It Is

年収マスター is a Japanese website for analyzing corporate annual income and business data. Its positioning is clear: helping job seekers, employees, and people considering a career change look up information such as average annual income, employee count, and sales revenue by company. It is not a typical SEO tool, but rather a vertical content/data site that can be used for career decisions, employer comparisons, and research on Japanese companies.

Core Features and Data

The site offers company search, company detail pages, and rankings for metrics such as average annual income, annual income growth rate, sales revenue, sales per employee, net profit, net profit per employee, number of employees, average age, and average years of service, with breakdowns by industry and region. The site states that it aggregates data for about 4,400 companies, while one sample ranking page shows a total of 4,687 companies. Its data mainly comes from publicly disclosed securities reports on EDINET and the National Tax Agency’s 民間給与実態統計調査, so transparency is relatively good. However, some fields such as annual income by age group and bonuses are estimated values, and the FAQ notes that when certain companies do not disclose data, some fields may be missing or shown as 0.

Pricing and Usage Restrictions

According to the terms of use, regular users can use 年収マスター for free, making it cost-effective for individual job-search scenarios. However, the site explicitly prohibits using all or part of the service for commercial purposes, such as business activities, without permission. For commercial use, users need to contact the site operator. The available text does not disclose any paid plans, payment methods, API access, or bulk licensing prices.

Pros and Cons

Its strengths are rich data dimensions, a clear ranking structure, and relatively explicit source explanations, making it suitable for quickly comparing compensation and business performance among listed Japanese companies. The drawbacks are also obvious: the site itself states that it does not guarantee the accuracy, completeness, reliability, or timeliness of its content; its coverage is mainly limited to companies that disclose securities reports and therefore cannot represent all Japanese employers; and the text does not show customer support, data downloads, API access, team collaboration, or system integration capabilities.

Who It’s For and Access from China

It is suitable for job seekers, career changers, international students interested in the Japanese job market, and individual users researching compensation at Japanese companies. For Chinese teams, if it is used for formal recruitment consulting or commercial reports, the original reports should be cross-checked and the commercial-use restrictions should be noted. The text does not provide information on access from mainland China, so the status is unknown; payment information is also not disclosed. Alternatives include EDINET, National Tax Agency statistics, OpenWork, and 転職会議, while comparable domestic Chinese platforms include 看准网, 职友集, and 脉脉.
