SGD to JPY in Tokyo: Complete Currency Exchange Guide 2026 — For Singapore Travelers
The biggest thing to know about Singapore dollars (S$) → yen is this: not many shops in Japan handle SGD, but the rates available back home in Singapore are among the best in the world. This guide covers the optimal route for SGD → JPY, walking through famous Singapore exchange spots like Mustafa Centre, your backup options in Tokyo, and smart electronic payment strategies.
TL;DR — The Bottom Line for SGD Travelers Heading to Tokyo
💡 Yen conversion note: A 5% rate gap on S$500 means about ¥2,900 lost (at roughly 1 SGD = ¥116). That is the price of a nice lunch in Tokyo.
Comparison ① Buy Yen in Singapore or Tokyo?
Mustafa Centre and The Arcade at Raffles Place in Singapore are among the world's top-tier money changers:
Location
SGD → JPY Rate (approx.)
Mustafa Centre (Little India)
Mid-market +0.1–0.3% (world best)
The Arcade (Raffles Place)
Mid-market +0.1–0.4%
Major Singapore banks (DBS / OCBC / UOB)
Mid-market +0.5–1.2%
Changi Airport (SIN)
Mid-market −1.0–2.5%
Tokyo street exchanges (Shinjuku-West / Ikebukuro)
Mid-market +1.5–2.5%
Tokyo airport counters
Mid-market −3.0–4.5%
Verdict: Mustafa > The Arcade > Singapore banks > Changi Airport > Tokyo street > Tokyo airport. Buying 90% of your yen at Mustafa is the strongest strategy in the world.

Comparison ③ Singapore-Issued Cards and Electronic Payments
Singapore-issued credit cards (Visa / Mastercard / Amex from DBS / OCBC / UOB) are widely accepted in Japan:
Store Category
Accepted?
Major department stores, convenience stores, chain shops

✅ (major cards supported)
Street food stalls, small independent shops
🔴 Limited
If you live in Singapore and hold a multi-currency account with DBS or OCBC, you can withdraw JPY directly or pay overseas through the account to minimize FX fees. Combining this with a Wise / Revolut card also works well.
Comparison ④ Using Wise / Revolut Cards
Singapore has one of the world's highest Wise / Revolut adoption rates, and many travelers heading to Japan already use them:

Cash users go to Mustafa; card users go with Wise / Revolut — the two main paths.
3 Mistakes Tourists Often Make
Exchanging everything at Changi or Narita airport → On S$500, that is ¥2,000–3,000 lost. Buying ahead at Mustafa is dramatically better.
Choosing DCC and paying in SGD: When a restaurant asks "in SGD?" and you say Yes → 3–7% lost. Always pay in JPY.
Expecting card payment at small shops: Street stalls and independent shops are often cash-only. Carry ¥10,000–20,000 in cash.

Q: Is Mustafa Centre really the best rate in the world?
A: Many money-changer review sites and travel blogs rate Mustafa as world-class. The combination of 24-hour operation, support for nearly every major currency, and rates of mid-market +0.1–0.3% is exceptionally good by global standards.
Q: How much yen can I buy in Singapore?
A: Singapore has effectively no export limit (you only need to declare cash above S$20,000). Around ¥500,000 per person is no problem at all.
Q: Wise / Revolut or a Singapore bank account — which is better?
A: If you already have a DBS or OCBC multi-currency account, go through the account; otherwise Wise / Revolut is convenient. For frequent visitors to Japan, using both is the most efficient mix.
Q: What should I do with leftover yen?
A: Singaporeans tend to visit Japan often, so keeping it for the next trip is the most efficient choice. For shorter-term storage, converting it to Suica or an Amazon gift card at airport Pocket Change kiosks is also an option.
Q: How can I find SGD-handling shops in Ginza or Shinjuku?
A: The World Currency Shop chain has many branches that handle SGD as one of the major currencies. The safest bet is to check online beforehand that the branch lists "SGD available" before heading over.
