At the bank:
- Please apply your hanko here.
- My... hanko? But, I do not have one...
- Aaah... Well... Goodbye.
In Japan (and other Asian countries), it is traditional practice to use a personal seal called "inkan" or "hanko" instead of a signature for signing documents.
Until recently, even foreigners were asked to do so! You can buy a hanko everywhere... But isn't it cool to make your own?! Would you chose a kanji or would write your name in katakana?
Tips: you will find a Seal Vending Machine at the "don quijote" in Takadanobaba!
