An unofficial study app for the Toriteki Homu Kentei (取適法務検定, formerly 下請法務検定), the Japanese exam on the Act on Proper Transactions with Small and Medium-Sized Entrusted Business Operators (SME Transactions Act, 取適法; formerly the Subcontract Act, 下請法). The amended Act took effect on 1 January 2026. The app is in Japanese.
Mock exams in the official format
Five non-overlapping mock exams of 50 four-choice questions in 90 minutes, 2 points each, pass at 70. Timer, review flags, a question grid, automatic marking when time runs out and results by topic.
Every question has a source
All 500 questions show the document they are based on (the Act, the Japan Fair Trade Commission and SME Agency textbook, guidelines and Q&A) with the relevant section, and a link to the original page.
Practical tools

- Payment due date check: the 60-day rule, the two-month rule for monthly closing and postponement for bank holidays.
- Late-payment interest: 14.6% a year, with the start date, number of days and amount.
Tool results are a study aid; check actual transactions against official materials or with an expert.
