A 外交官 (gaikoukan) is a diplomat who represents their country's government in foreign affairs.

At teinen, employees may receive retirement benefits, pensions, and other post-retirement support. Some companies offer rehiring programs where retirees can continue working in a different capacity or on a part-time basis. The concept of teinen reflects Japan's structured approach to employment and workforce management, ensuring a planned transition from active employment to retirement. It also addresses the need for workforce renewal and provides opportunities for younger employees to advance within the organization.

割印 (wariin) refers to a type of seal used in Japanese documents to prevent tampering and verify authenticity. It is created by placing a personal seal (hanko) across two or more pages of a document, ensuring that the pages belong together and have not been altered.

Using wariin is an important part of Japanese documentation procedures, reflecting the cultural emphasis on meticulousness and accuracy in formal agreements and record-keeping.
