Best time of day to exchange money in Japan in 2026
⚡ 30-Second Answer: Best exchange timing = weekday 10-12am (latest bank rates reflected, pre-rush). Avoid: ①month/quarter end (FX volatility), ②weekends (most shops carry pricier spreads), ③24h after BoJ policy announcements (high volatility), ④holidays. Within a day, morning is cheapest; evening may see shop-adjusted markups. Wise/Revolut runs 24h at the same mid rate.

Late morning (10:30–12:00 JST) is the optimal time to
exchange money at Tokyo dedicated exchange shops — the rates are
fresh from the day's open, queues are shorter than peak hours,
and most shops have updated their displays. Avoid early
morning (9:00 and earlier) when many shops use yesterday's rate,
and avoid late afternoon (16:00+) when staff may be tired and
rates may be slightly stale.
TL;DR
Best: 10:30–12:00 JST.
Avoid: before 9:30 (stale rates) and after 17:00 (stale
rates again).
OK: any weekday daytime; ATMs are real-time so timing
matters less.
Bonus: late morning gives best ¥110 ATM fee window.
What makes late morning the sweet spot?
Three factors:
1. Rates are fresh
Most Tokyo dedicated exchange shops update rates 1–3 times
daily. The first update is typically around 10:00 — by 10:30,
rates reflect the current day's market open.
2. Queues are shorter
Tourist queues peak around lunch (12:30–14:00). Late morning
has shorter waits.
3. Bank/network freshness
The card-network exchange rate (used by 7-Eleven ATMs and
contactless tap) is real-time, but the daily reference matters
for cross-checks.
The bottom line: between 10:30 and 12:00, you can
typically pick the day's best Tokyo shop rate before the
lunchtime queue forms — the convenience plus the rate
combination is optimal.
When are rates worst?
Time
Why
Before 9:30
Many shops use yesterday's rate; staff still arriving
After 17:00
Stale rates (same as morning's update); fatigue affects service
12:30–14:00 (lunchtime peak)
Queues; staff under pressure
Late evening (21:00+)
Most shops closed; only 24/7 options
Weekends
Some shops close; rate updates reduced
What about ATMs and card transactions?
ATM and card transactions use the card network's real-time
rate, so timing has minimal impact. The only ATM-timing factor
is the fee window: 8:00–18:00 weekday gets ¥110 fee
(Seven Bank); other times ¥220.
What this means for your trip
✅ Plan large exchanges for 10:30–12:00 JST.
✅ Avoid pre-9:00 for dedicated shops; use ATM if early.
✅ Avoid 21:00+ for dedicated shops; use 7-Eleven ATM if
late.
✅ For ATM withdrawals, the time-of-day matters only for
the ¥110/¥220 fee structure.
⚠️ Don't try to time the forex market in a 7-day trip —
daily moves are smaller than the timing-vs-spread tradeoffs.
Frequently asked questions
Are weekends as good as weekdays?
No — many shops have shorter weekend hours and may not update
rates as frequently. Plan large exchanges for weekday daytime.
What about 24-hour Don Quijote in-store exchange?
Don Quijote operates with a daily-set rate; doesn't update
through the day. Late-night use is convenience-driven, not
rate-driven.
Are mornings before 9:00 ever good?
For real-time-rate ATMs (7-Eleven Seven Bank), yes — the rate
reflects the current network rate. For dedicated shops, no —
they typically use yesterday's rate.
Does the exchange rate vary by which shop?
Yes — the same time-of-day, different shops can offer rates
differing by 1.5–2.5%. Late morning still wins; the shop choice
is more impactful than the time-of-day choice.
