Japan arrival guide (resident card, social security, My Number, pension…)

According to the Japanese government,

The “Individual Number” system assigns each individual who resides in Japan a number. It is a system that enables your information which is held by several administrative offices to be confirmed and measures for social security, tax, and disaster prevention purposes to be conducted promptly and precisely. The Individual Number System contributes to the more effective procedures by administrative offices, improvement of convenience of residents, and accomplishment of fair and impartial society.

Possession of My Number is not required, but it can simplify certain tasks.

What is this number good for?

• Simplify administrative formalities relating to tax declaration and social security
• Allow you to send money abroad
• Can act as official ID
• Allow you to print documents directly at conveniences stores
• Authorize use of PayPay (equivalent to Paypal). Sometimes the government offers PayPay points, which can be converted to yen, for holders of a My Number.
• Some banks require clients to have one

Many Japanese criticize My Number, as they consider it too invasive in its tracking of personal transactions. The government affirms that it is a tool to help better redistribute wealth via social security systems. In practice, it is also a mechanism to combat tax evasion.

Though the government has put many incentives in place to promote it, you are NOT required to apply for My Number.

Signing up for My Number

You can apply either online or at your city hall. You will then need to make an appointment to pick up your card at the city hall once the card is issued. The card on your number will consist of 12 digits, valid for your entire life.

There are two types of cards:

• A temporary paper card (sufficient for WHV holders)
• A card with a chip. This takes more time to issue and is only worth considering if you plan to stay in Japan permanently.
