Smart Exchange auto-machines: where to find them and how to use the 541-machine network

⚡ 30-Second Answer: Smart exchange machines (automated kiosks): roughly mid-market +1.0% to +1.5% (i.e. about 1% below mid), hours follow the host venue (most close 22:00-23:00, not 24h), located at airports, major stations, dept-store basements. Clearly better than an airport counter (+3.5% to +5.0%), slightly worse than a Wise/Revolut ATM withdrawal (+0.5%). Brands like Smart Exchange and Pocket Change. Multi-language UI (EN/ZH/KO), ¥5,000-200,000 range. Better than counters on convenience, not on rate.

Smart Exchange runs 541 currency-exchange auto-machines across Japan, accepting 12 currencies (USD/EUR/CNY/KRW/TWD/HKD/GBP/AUD/CAD/SGD/THB/MYR) and dispensing JPY only. The machines sit inside game centres (GiGO), electronics chains (Yodobashi Camera, Bic Camera), train stations, and major airports. Rates are about 1% below the mid-market — clearly better than an airport counter (which typically takes 3.5–5%) but slightly worse than withdrawing yen from a Japanese ATM with a Wise or Revolut card.

TL;DR

• 541 machines nationwide — Tokyo 275, Osaka 125, Kyoto 34, Hokkaido 21, Fukuoka 19, Okinawa 16
• 12 currencies in, JPY out only
• Hours: matches the host building. Most close at 22:00–23:00; some game centres run later.
• Rate: roughly mid-market + 1.0% to 1.5% (varies by venue)
• No passport required at most venues. Single transaction cap ~ USD 5,000 equivalent.

1. Where to find a machine

Smart Exchange has a diverse footprint of host venues, falling into five buckets:

a. Game centres (most discoverable for tourists)

• GiGO — Ikebukuro, Shinjuku Kabukicho, Shin-Okubo, Akihabara, Shibuya, and 14+ locations total
• Taito Station — selected branches

Useful because tourists running into a GiGO see the bright Smart Exchange signage even without looking for it. Late-evening GiGO branches stay open until midnight; the machine inside follows the host hours.

b. Electronics retailers (along the standard tourist track)

• Yodobashi Camera — Multimedia Akiba, Multimedia Shinjuku-West, and 6+ branches
• Bic Camera — Ikebukuro Honten, Shinjuku-West, Shibuya East, Yurakucho, and 10+ branches

Combo win: change foreign currency, then spend the yen on-site for an 8–10% tax-free discount at the same retailer. Net effective rate beats most dedicated counters when the visitor is buying electronics anyway.

c. Train stations (the commuter's friend)

• JR Tokyo Station — Yaesu Central exit, Nihonbashi exit ATM corner
• JR Yurakucho Station — Kyobashi exit
• JR Shimbashi Station
• JR Shinjuku Station — Central West, South
• Osaka / Umeda stations
• Kyoto Station

Station-installed machines run until the last train; useful for spillover between metro rides without leaving the gate area.

d. Tourist retail buildings

• Ginza Mitsukoshi (Japan Duty Free GINZA, 8F)
• Atre Shinagawa
• @cosme TOKYO (Harajuku)
• Grand Green Osaka
• MEGA Don Quijote select branches

e. Airports

• Naha, New Chitose, Kansai Int'l, Fukuoka, Sendai, Hiroshima airports — at least 5 airports covered.

2. Top 10 areas by machine count

The top 10 areas hold 406 machines (75%) of the national fleet.

3. How to use one (60 seconds)

1. Pick a language on the touchscreen (English / Chinese / Korean / Thai / Japanese).
2. Insert your foreign-currency notes (e.g. a $100 bill or a ¥10,000-equivalent note).
3. Confirm the rate shown on-screen, then press the exchange button.
4. Yen comes out, broken into the right denominations including coins.

Notes only — no coin acceptance. One transaction caps at roughly USD 5,000-equivalent; the per-machine limit varies.

Passport — needed or not?

It depends on the host venue:

• Tourist / retail venues: no passport required, no photo capture
• Bank-affiliated machines: passport image scan required

Either way, watch the ¥1 million / 24-hour cumulative limit under the AML rules — exchange in multiple transactions to stay below it.
