What to do with leftover yen at the end of your Japan trip in 2026

Most travelers leave Japan with ¥3,000–¥10,000 of leftover yen they couldn't easily plan into their last day's budget. The worst option is the airport re-exchange counter (typical loss: 3–5 % on the yen-back conversion). Better options: spend it at the airport, convert via Pocket Change to e-money, or save it for next trip — yen doesn't expire. This guide ranks every option with the actual rate-loss math and strategic guidance for each amount.

TL;DR

• Save for next trip is often the best choice — zero loss, no expiration, ready for return.
• Pocket Change at the airport converts coins and small bills to PayPay credit, USD/EUR e-money, or Apple gift cards — useful for awkward leftover combinations.
• Airport re-exchange counter typically loses 3–5 % on the yen-back direction; avoid for amounts under ¥10,000.
• Last-minute purchases at duty-free is a fine spend strategy if you don't want the cash to sit.

How much leftover yen do most travelers have?

Leftover-yen amounts cluster in three ranges:

| Trip type | Typical leftover | Why | |---|---|---| | Heavy planner, urban-only | ¥1,000–¥3,000 | Day-1 buffer over-purchased | | Mixed trip with cash buffers | ¥3,000–¥8,000 | Multiple safety margins | | Festival/ryokan-included | ¥5,000–¥15,000 | Hard to predict cash needs precisely | | Multi-week traveler | ¥10,000–¥30,000+ | Cash accumulates from frequent withdrawals |

Most travelers fall in the ¥3,000–¥8,000 range — small enough that the airport re-exchange rate gap matters, large enough to be worth strategic handling.

The single quotable fact: for ¥5,000 of leftover yen, the loss at an airport re-exchange counter is roughly ¥250 (5 %) — compared to ¥0 for saving it or ¥50 (1 %) for Pocket Change conversion.

Option 1 — Save for next trip (zero loss)

The simplest option: pocket the yen and save it for your next Japan visit. Yen doesn't expire; the Bank of Japan honors notes issued back to the 1885 era. Many travelers keep a small ¥3,000– ¥5,000 "Japan starter kit" for future trips.

When this works well:

• You travel to Japan often (1+ trips per year)
• The amount is small (under ¥10,000)
• You don't need the cash for anything else

When this doesn't work:

• One-time visit; no future plans
• Large amount (¥30,000+) you'd rather have liquid
• Currency volatility concerns (rate could shift before next trip)

Option 2 — Pocket Change at the airport (~1 % loss)

Pocket Change machines at major airports (Haneda, Narita, KIX) and many central Tokyo locations convert leftover Japanese cash to:

• PayPay credit (best rate; useful if you'll return)
• Apple Gift Card or other e-cards (decent rate)
• USD, EUR, GBP, KRW e-money (rates 0.5–1.5 % below mid-market)
• Bitcoin or other crypto (variable)

The rate gap from mid-market is typically 0.5–1.5 %, far better than the 3–5 % loss at airport re-exchange counters.

When this works well:

• Loose change (coins under ¥500) that exchange shops won't take
• Small bills (¥1,000) plus loose change
• You want to keep the value liquid in your home currency
• You'll return to Japan but want the value spendable elsewhere

When this doesn't work:

• Amount over ¥30,000 (better to use a regular exchange)
• You don't have a way to use PayPay credit (no Japan return)

Option 3 — Last-minute spending at the airport (no loss)

If you have ¥5,000–¥15,000 of leftover yen, spending at the airport eliminates the conversion entirely. Options:

• Duty-free shops at international departure gates
• Last-minute omiyage (gifts) for friends and family
• Snacks and drinks for the flight
• A meal at an airport restaurant
• Books or stationery at airport bookstores

For larger amounts, this can actually save money by buying duty-free goods you would have bought at home anyway.

Option 4 — Airport re-exchange counter (3–5 % loss)

The conventional choice — and the worst rate-wise:

| Source | Rate vs mid-market | ¥5,000 loss | |---|---|---| | Mid-market reference | 0 % | n/a | | Best in-town buy-back rate | −1.0 to −1.5 % | ¥50–¥75 | | Pocket Change | ~−1.0 to −1.5 % | ¥50–¥75 | | Average airport re-exchange | −3.0 to −5.0 % | ¥150–¥250 | | Hotel front-desk re-exchange | −5.0 to −7.0 % | ¥250–¥350 |

Skip airport re-exchange for amounts under ¥30,000. The flat rate-loss makes the math very unfavorable for small amounts.

Option 5 — In-town re-exchange before flying out (1.0–1.5 % loss)

If you have time before heading to the airport, re-exchanging in central Tokyo is meaningfully better than the airport rate:

• Dollar Ranger Shinjuku West or Ginza 3-chome (yen-back rate 0.5–1.5 % below mid-market)
• World Currency Shop branches (similar rate)
• Travelex (slightly worse but more locations)

This makes sense for amounts ¥30,000+ where the rate gap is material. For ¥5,000 leftovers, the time cost (¥45 minutes round trip) typically isn't worth ¥100 saved.

What about specific countries' homebound rates?

| Country | Rate gap (yen → home cur) | Notes | |---|---|---| | US (Wise/Revolut) | 0.4 % flat | Best option for re-conversion | | US (typical bank) | 3–5 % below mid-market | Avoid; very poor | | EU (Wise/Revolut) | 0.4 % flat | Same as US | | EU (typical bank) | 1–3 % below mid-market | Better than US bank, still not great | | Korea (typical bank) | 4–5 % below mid-market | Avoid | | Korea (Toss FX) | varies | Check before exchanging | | China (cash to CNY) | varies | Limited liquidity in some banks |

For most travelers: save the yen for next trip if returning; Pocket Change if not returning soon; Wise/Revolut card to spend if you have leftover with the card.

What's the strategic guidance by amount?

| Leftover amount | Best option | |---|---| | Under ¥1,000 | Save for next trip OR last-minute coffee | | ¥1,000–¥5,000 | Pocket Change (coins & small bills); save for next trip | | ¥5,000–¥10,000 | Spend at airport duty-free OR save for next trip | | ¥10,000–¥30,000 | In-town re-exchange in central Tokyo before flying | | ¥30,000+ | In-town re-exchange OR save for next trip |

What this means for your trip

• ✅ Plan to leave with about ¥3,000–¥5,000 of yen rather than zero — easier and saves rate loss.
• ✅ Use Pocket Change at the airport for awkward combinations (coins + small bills).
• ✅ Spend leftover at airport duty-free if you'd want the goods anyway.
• ✅ Save ¥3,000–¥5,000 as a "Japan starter kit" for next trip if returning within 12–24 months.
• ⚠️ Avoid airport re-exchange counters for amounts under ¥10,000.
• ⚠️ Avoid hotel front-desk re-exchange — worst rate available.

Frequently asked questions

Will my home bank exchange yen for me?

Some will, some won't. US banks typically don't accept yen for deposit; many EU banks do but at poor rates. Wise and Revolut let you receive JPY into your account if you have the multi- currency feature enabled.

Can I deposit leftover yen to my Wise account?

No — Wise is a card platform, not a deposit-holding account for foreign currencies in physical form. To convert, use Pocket Change or in-town re-exchange.

How long can I save yen for?

Indefinitely. Yen is legal tender; even old (pre-2024) banknotes remain valid. Many travelers keep a "Japan kit" for years.

What about coins?

Coin re-exchange is usually impractical at airport counters and banks (most reject coins). Pocket Change kiosks accept all denominations including coins. For amounts under ¥500 in coins, just spend at the airport vending machines or duty-free.

Can I send leftover yen to a Japanese friend's account?

Yes — via Wise Japan account routing. For amounts over ¥5,000, this is a good option if you have a Japanese friend who can receive.

What about the new yen banknotes (post-2024)?

Both old and new banknotes are valid. If you have old notes with significant wear, they're more likely to be accepted at banks than at exchange shops or vending machines.

Should I save my Suica/Pasmo IC card balance?

Yes — IC card balances also don't expire. Apple Wallet versions sync to your iCloud account; physical cards retain their balance indefinitely.
