What It Is

勤労の獅子 is a Japanese cloud-based attendance management system provided by エス・エー・エス株式会社. It emphasizes a “support-based” approach: dedicated attendance consultants and support teams assist with everything from implementation and initial setup to ongoing operation and maintenance. It mainly addresses the time-consuming calculations, complex rules, and lack of transparency associated with paper records, Excel, and time cards.

Core Capabilities

The system covers modules such as clock-in/out, Article 36 agreements, annual paid leave, working-time tracking, shifts, project-based work hours, workflows, permissions, and remote work. Its strength lies in adapting to complex rules: it can apply different aggregation standards by individual, supports over 100,000 shift patterns, 48-hour overnight shifts, one-month variable working-hour systems, one- to three-month flextime systems, multiple clock-ins, and calculations based on expanded item conditions. Clock-in methods are also extensive, including web, mobile phones, IC cards, finger vein authentication, dedicated time recorders, LINE WORKS, and カラ・レコ.

Pricing and Integrations

Pricing is disclosed as starting from 150 yen per person per month, varying by option combination, with an initial setup fee charged separately. Managers who do not clock in/out and only manage employees do not incur a monthly fee. A trial of up to 30 days is available. For integrations, the system lists employee information synchronization with SmartHR, clock-in/out and balance checks via LINE WORKS, and supports CSV/Excel exchange with payroll software, shift schedules, and master data.

Pros and Cons

Its advantages include strong implementation support, flexible configuration, comprehensive clock-in options, and cloud updates in line with revisions to Japanese law. For security, it supports SAML 2.0, OIDC, and OAuth 2.0; attendance data is retained for at least five years; and a security checklist is publicly available. Limitations include the fact that actual pricing requires inquiry and some capabilities are optional add-ons. The FAQ clearly states that overseas locations cannot use the service and that VPNs are not supported. The remote work option also requires a Windows-only application.

Best Fit and Access from China

It is better suited to small, medium, and mid-to-large companies within Japan, especially organizations in manufacturing, hospitality, healthcare, childcare, multi-site operations, and complex shift-based environments. There is insufficient information for unified cross-border attendance management or use cases in mainland China. The website’s accessibility from China has not been disclosed, so it is assessed as unknown.
