KRW to JPY in 2026: a Korean tourist's quick guide to Japan money

⚡ 30-Second Answer: KRW → JPY carries wider spreads than USD/EUR (roughly 1-6% depending on venue). At a good downtown Tokyo shop you'll land roughly mid −1% to −2.5% in hand — check the live KRW rate, since these move daily. Best rates: Shin-Okubo's Korean-run shops and Shinjuku West counters. Exchange after you arrive: Korean bank counters run several percent below mid; the one exception worth checking before flying is Korean fintech (Toss FX, Kakao Pay FX). Rates here are indicative only — yenfinder live-tracks World Currency Shop, so use it as your reference point and confirm the rest on the day.

For Korean tourists in Japan — the largest source country for Japanese inbound tourism — the best KRW-to-JPY conversion path is cash exchange at Shinjuku, Shin-Okubo, or Ginza shops (typically around mid −1% to −2.5%, varying by shop and day) plus a no-FX-fee Korean debit card or Wise/Revolut for digital spending. KRW rates in Tokyo are notably competitive thanks to high-volume tourist flow; Shin-Okubo (Tokyo's Korea Town) often has the day's best rates due to the combined Korean-resident and tourist demand. This guide is the master reference for Korean visitors with KRW to convert.

TL;DR

• Best KRW cash exchange in Tokyo: Shin-Okubo's Korean-owned shops, Dollar Ranger Shinjuku West, World Currency Shop Shinjuku — typically around mid −1% to −2.5% (check the live rate).
• Best card: a no-FX-fee Korean debit (e.g., Toss Bank, KB StarShot, Hana 1Q) — beats traditional Korean credit cards by 1–2%.
• Best ATM: 7-Eleven Seven Bank, foreign card support, ¥110– ¥220 fee.
• Cash exchange beats Korean bank exchange by about 2–3% (Korean bank rates are typically 4–5% below mid-market).

What's the KRW-to-JPY rate landscape today?

The live mid-market rate is the reference — KRW/JPY moves daily, so treat the figures below as relative gaps vs mid, not fixed rates. Check the live KRW rate before you exchange (yenfinder live-tracks World Currency Shop, so use it as your anchor):

These are indicative and vary by shop and day — a cash buy rate is always below mid. Note: Korean Won is typically displayed in per-100 unit terms (i.e. JPY per 100 KRW) on most Tokyo exchange boards.

Where do I exchange KRW in Tokyo?

Shin-Okubo — Tokyo's Korea Town

Two stops north of Shinjuku on the JR Yamanote Line, Shin-Okubo is Tokyo's largest Korean community and has the highest density of Korean-language services in the city:

• Korean-owned exchange shops along the main shopping street — competitive on KRW because of dual demand (Korean residents + Korean tourists)
• Smaller pawn shops with FX windows — variable rates; check the day's display

Shinjuku West Exit

• Dollar Ranger Shinjuku West — KRW is in their 14-currency menu; rates competitive
• World Currency Shop Shinjuku — official rate page; KRW one of their core currencies
• Travelex Keio Shinjuku — 31 currencies including KRW

Ginza 3-chome

• Dollar Ranger Ginza — KRW competitive

Shibuya

• World Currency Shop Shibuya — auto-updated rates

What card should I bring as a Korean visitor?

For Korean-issued cards, the hierarchy in 2026:

Wise is the universal recommendation for Korean travelers with frequent international trips; Toss Bank is the local fintech alternative for Korea-resident users.

What about UnionPay or Korean QR systems?

• UnionPay credit cards issued by Korean banks: work at 80%+ of Tokyo merchants; conversion at UnionPay rate (~1–1.5% above mid-market).
• Naver Pay / Kakao Pay: limited Japanese merchant acceptance — primarily expanding into Southeast Asia first. Don't rely on them as primary in Japan.
• Toss Pay: Japanese acceptance is minimal in 2026.

For Korean tourists, the practical mix is cash exchange + Wise/ Toss Bank + UnionPay credit as the three layers covering different scenarios.

What's the right cash-vs-card split for a Korean visitor?

Same as for other tourists (article #4):

Cash budget: ₩100,000–₩200,000 worth (¥10,000–¥21,000) for a 7-day city trip; more for ryokan-included or rural trips.

One more thing, from one cashless-society resident to another: we know carrying ¥10,000-20,000 in paper feels odd when everything at home is a tap. In Japan it's genuinely fine — street crime is rare, lost wallets famously come back, and handing over cash is still an everyday ritual here. Treat it as part of the trip.

→ Article #13: How much cash to bring.

Should I exchange KRW before flying or after arriving?

Almost always after. Korean bank rates are typically 4–5% below mid-market — about the same as Japanese hotel front desks (the worst rates available in Japan). The exception is some Korean fintech platforms (Toss FX, Kakao Pay's foreign currency service) that offer better rates — check before flying.

For most Korean tourists:

• Bring ₩50,000–₩100,000 cash as emergency buffer
• Use Wise / Toss Bank / UnionPay for digital spending
• Exchange the bulk at Shin-Okubo or Shinjuku within first 2 days of arrival

What about regional Korean travelers (Busan, Daegu)?

For Korean tourists not from Seoul:

• The same Tokyo cash exchange logic applies
• Korean fintech services (Toss, Kakao Pay) work the same way
• Regional Korean banks may have higher FX fees — check before flying

For tourists arriving via Kansai Airport (Osaka), see article #41 for Osaka exchange details — Osaka's Shinsaibashi has KRW rates often comparable to Tokyo's.

What this means for your trip

• ✅ Use a no-FX-fee card (Wise, Toss Bank) for ~80% of Japan spending.
• ✅ Exchange KRW cash at Shin-Okubo, Shinjuku West Exit, or Ginza for the best rates.
• ✅ Use 7-Eleven Seven Bank ATMs for after-hours cash needs via foreign card.
• ✅ Carry ¥10,000–¥21,000 cash buffer for cash-only situations.
• ⚠️ Decline DCC at every card terminal — choose JPY.
• ⚠️ Avoid hotel front-desk KRW exchange — worst rate available.
• ⚠️ Korean QR systems (Naver Pay, Kakao Pay) have limited Japanese acceptance; don't rely on them as primary.

Frequently asked questions

Are Tokyo KRW rates better than Seoul JPY rates?

On most days, Tokyo's best KRW rate beats Seoul's best JPY rate by 1–2%. Korean bank exchange is particularly poor (4–5% below mid-market). Korean fintech services (Toss FX, Kakao Pay foreign currency) are competitive but rates vary.

Will my Korean card with chip-and-PIN work?

Yes — Korea uses chip-and-PIN; Japan uses chip-and-PIN. Most Japanese terminals handle Korean cards smoothly. Some older signature-only terminals may have issues; carry a backup card.

Can I use my Korean Naver Pay or Kakao Pay in Tokyo?

Limited acceptance. Some tourist-frequent merchants accept Naver Pay (especially in Shin-Okubo for Korean-language transactions), but most Japanese shops don't have these systems. Don't rely on them as primary.

What about T-money (Korean transit card)?

T-money doesn't work in Japan — these are regional systems. Use Suica or Pasmo for Japanese transit (article #73).

Is Shin-Okubo really the best place for KRW exchange?

On most days, yes — the dual demand from Korean residents and Korean tourists keeps spreads tight. Shinjuku and Ginza are competitive but Shin-Okubo often edges them slightly — confirm on the live rate, since the day-to-day order changes.

Do Tokyo shops accept torn or marked KRW notes?

Same rule as USD — clean post-2009 notes only. Heavily worn or marked Korean notes may be refused. Bring crisp bills if you can.

What about Korean tax-refund processes?

Korean tourists qualify for Japanese tax-free shopping the same way as other foreign visitors — items over ¥5,000 at certified retailers, with passport. → article #88.

Will my Korean phone's mobile data work for in-Japan currency

apps? Yes — Korean roaming or Japanese SIM (e.g., from Sakura Mobile or Mobal) lets you use Wise, Toss Bank, or any other app while in Japan. KT and SK Telecom have decent Japan roaming rates; local SIM may be cheaper for trips over 5 days.
