THB to JPY for Thai tourists in 2026: where to exchange and digital alternatives

Thai tourists in Japan exchange THB primarily at Travelex Keio Shinjuku (deepest 31-currency inventory) or Ninja Money Exchange (specialty for rare Asian currencies). Rates lag Tokyo's USD top by 0.5–1.0%, but acceptable spreads are achievable at 0.5% below mid-market. A no-FX-fee card (Wise or local Thai fintech) covers digital spending; UnionPay credit (issued by some Thai banks) works as backup.

TL;DR

• Best THB cash exchange: Travelex Keio Shinjuku (31 currencies); Ninja Money Exchange.
• Best card: Wise debit (Thailand) or local Thai fintech.
• Best ATM: 7-Eleven Seven Bank with Wise card.
• Pre-arrival exchange in Thailand: typically 1–2% better than in Japan.

What's the rate landscape for THB?

For ฿20,000 (~¥85,000 at mid-market):

| Source | Approx. rate (1 THB =) | Yen received | vs mid-market | |---|---|---|---| | Mid-market reference | 4.45 | ¥89,000 | — | | Travelex Keio Shinjuku | 4.42 | ¥88,400 | −0.67% | | Ninja Money Exchange | 4.40 | ¥88,000 | −1.12% | | Average Tokyo shop | 4.30 | ¥86,000 | −3.37% | | Tokyo airport counter | 4.20 | ¥84,000 | −5.62% | | 7-Eleven Seven Bank ATM (Wise card) | ~4.43 | ¥88,600 | −0.45% |

Should I exchange THB before flying?

Often yes for Thai tourists. Thai bank rates and Thai exchange shops are typically 1–2% better than Japanese THB rates because:

• Thailand has higher THB liquidity domestically
• Tourist demand keeps Thai exchange shop spreads tight
• Japanese shops carry less THB inventory

For Thai tourists planning ฿50,000+ of yen needs:

• Consider exchanging in Thailand at competitive shops (e.g., SuperRich, Kasikornbank international branches)
• Then transport the JPY safely to Japan

What about digital alternatives?

Thai tourists' card options in Japan:

| Card | FX fee | Notes | |---|---|---| | Wise debit (Thailand) | 0.41% flat | Best universal option | | Krungthai TMB Touch | varies | Thai fintech; some plans 0% FX | | TrueMoney | n/a | Limited Japan acceptance | | K Bank international card | 1–2% | Thai bank cards | | UnionPay credit (some Thai banks) | 1–1.5% | Asia-friendly backup | | Standard Thai credit card | 2.5–3% | Avoid |

For Thai tourists, the practical mix is cash + Wise + UnionPay covering 99% of urban Japan spending.
