Carrying cash from Singapore to Japan

Two separate rules apply to any cash journey: one where you leave, one where you arrive.

Do you need to declare?

Yes: and on both legs of the journey. Leaving Singapore, Immigration & Checkpoints Authority requires a declaration above SGD 20,000. Entering Japan, Japan Customs requires a declaration above JPY 1,000,000. The two rules are independent: satisfying one does not satisfy the other.

The two legs

LegLimitFormAuthority
Leaving Singapore SGD 20,000 CBNI declaration (via the Singapore Arrival Card or the official app) Immigration & Checkpoints Authority
Entering Japan JPY 1,000,000 Declaration of Carrying of Means of Payment Japan Customs

The same declaration is required when leaving.

Required when the total exceeds ¥1,000,000 or its equivalent. The threshold falls to ¥100,000 if you are travelling to or from North Korea.

If you do not declare

Singapore: An offence under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992.

Japan: Penalties under the Foreign Exchange and Foreign Trade Act.

Neither threshold on this route is a cap: you may carry more, but above it the duty is to report the cash, not to keep under the figure. Failing to report is the offence.

Currencies

Singapore uses SGD; Japan uses JPY.
