What It Is

hakken is a margin-rate / intermediary spread database for Japan’s staffing dispatch industry. It organizes 45,450 records of dispatch companies nationwide based on publicly available information from the Ministry of Health, Labour and Welfare. Its core purpose is not to provide recruitment transactions or an enterprise management system, but to let job seekers, career changers, and researchers freely search and compare information such as dispatch company マージン率, dispatch fees, wages, and the difference between them.

Core Features and Data

Based on the crawled content, hakken offers company-name search, company data pages, filtering by prefecture, industry, and margin-rate range, as well as sorting by margin rate. The site also explains the margin-rate formula, notes that the national average is around 30%–35%, and uses below 20% as a general reference point for a low margin rate. It also cautions that a high margin rate does not necessarily indicate illegality or exploitation, as it may include costs such as social insurance, employment insurance, paid leave, and training. Its editorial policy emphasizes that it uses only official primary data from the Ministry of Health, Labour and Welfare and does not add speculative processing.

Pricing, Collaboration, and Technical Capabilities

The website clearly states that it organizes public data into a format that anyone can compare and research for free. No subscription plans, enterprise editions, paid downloads, or payment methods were found. From an enterprise software evaluation perspective, it lacks information on account systems, team collaboration, access controls, third-party integrations, APIs, data export, SLAs, and developer documentation. As a result, it is better suited as a public lookup tool than as an internal enterprise data platform.

Pros and Cons

Its strengths are broad data coverage, clear sourcing, practical search dimensions, and relatively neutral explanations of sensitive indicators, which help reduce the risk of misinterpretation. Its drawbacks are that the operator information appears to indicate an individual operator and support channels are limited. The data update frequency, timeliness of accuracy correction workflows, and long-term maintenance capacity are not fully disclosed. Its functionality is also focused on Japan’s dispatch staffing market, making its use cases relatively narrow for non-Japanese users.

Who It’s For and Access from China

hakken is suitable for people planning to find work in Japan through dispatch companies and compare dispatch company conditions. It is also useful for individuals or organizations researching Japan’s temporary staffing market. Access from mainland China is not reflected in the available text and is therefore unknown. Payment is not a major concern for now, as no paid offering was found. For research into local Chinese labor services or recruitment, local recruitment platforms, corporate credit databases, or government open data would be more appropriate alternatives.
