Chapter 1: Introduction to Revenue Stamps
First, it is important to understand 印紙税 (inshi-zei, stamp tax) in Japan. This is a tax required for certain documents, such as contracts and receipts.
To pay this tax, a special stamp called 収入印紙 (shūnyū inshi, Revenue Stamp Japan) must be attached to the document. These stamps look like postage stamps but are used for tax payment instead of mailing. Once attached, they show that the required tax has been accounted for. However, the tax is only considered officially paid when the stamp is marked with a seal (hanko) or a signature to prevent reuse.

Chapter 2: Why Are They Important?
Revenue stamps (収入印紙) are required to pay stamp tax (印紙税). If they are not used when necessary, it is considered tax evasion.
The penalties for not paying the required tax vary depending on the situation. However, if the necessary revenue stamp is not affixed by the time the taxable document is created, a penalty tax may be imposed. This penalty is three times the original stamp tax amount—which includes the unpaid tax plus a fine that is twice the unpaid amount.
To avoid unnecessary fines, it is important to check whether a revenue stamp is needed before finalizing any official document.

Chapter 5: How to Purchase Revenue Stamps
Revenue stamps (収入印紙) can be purchased at various locations. You can buy them at post offices (郵便局) and legal affairs bureaus (法務局). In some cases, they are also available at convenience stores and liquor or tobacco shops.
If you see stickers that say “印紙” (stamp) or “郵便” (post) on the window, you can purchase revenue stamps there. However, convenience stores typically only carry smaller denominations, such as ¥200 worth of revenue stamps. For higher amounts, it is more convenient to visit a post office or legal affairs bureau.
