十萬日幣等於多少台幣？2025年日圓兌換全攻略

The pressure of TWD depreciation is intensifying, and the 8.7% appreciation of the JPY as good news has attracted more and more attention. But before you decide to exchange for JPY, be sure to clarify one question: how much is 100,000 JPY actually worth in TWD? Based on the exchange rate as of December 10, 2025, with a cash selling rate of 0.2060 from Taiwan Bank, 100,000 JPY is approximately 20,600 TWD. However, this number can fluctuate by 200-1,000 TWD depending on the exchange method and rate type chosen.

Why is exchanging for JPY now a hot topic?

The Bank of Japan is on the verge of raising interest rates—recent hawkish comments from Governor Ueda Kazuo have pushed market expectations to 80%, with a rate hike of 0.25 basis points to 0.75% expected on December 19 (a 30-year high). At the same time, the yen, as one of the world’s three major safe-haven currencies (USD, CHF, JPY), naturally carries a protective halo during periods of global economic instability.

In fact, the use of the yen has long surpassed tourism: travel expenses (shopping in Tokyo, skiing in Hokkaido), purchasing agents and online shopping (Japanese cosmetics, anime merchandise), and even investment hedging (JPY fixed deposits with 1.5-1.8% annual interest, ETF dollar-cost averaging). In the second half of the year, Taiwan’s foreign exchange demand grew by 25%, mainly driven by these three needs.

The showdown of exchange channels: which method is most cost-effective?

Many think that exchanging for yen at banks is enough, but in reality, the spread alone can cost you several cups of bubble tea. Based on the latest data in 2025, we’ve summarized four major exchange channels and estimated costs using a benchmark of exchanging 50,000 TWD.

Option 1: Foreign currency ATM—fast but limited

Using a chip-enabled financial card at a bank’s foreign currency ATM to withdraw cash in JPY supports 24-hour operation, with a cross-bank fee of only 5 TWD. E.SUN Bank’s foreign currency ATM allows withdrawal from a TWD account, with a daily limit of 150,000 TWD and no exchange fee. However, after the new regulations in 2025, many banks’ third-category digital accounts have lowered their daily limit to 100,000 TWD.

Advantages: instant withdrawal, high flexibility, low cross-bank fees
Disadvantages: limited locations (~200 nationwide), fixed denominations (1,000/5,000/10,000 JPY), cash may sell out during peak hours
Estimated cost: about 800-1,200 TWD loss on 50,000 TWD
Suitable for: urgent needs, no time to visit banks, busy professionals valuing immediacy

Option 2: In-branch cash exchange—most traditional but most expensive

Carrying TWD cash directly to a bank branch or airport counter to exchange for cash JPY. This is the most traditional method but uses the “cash selling rate” (about 1-2% worse than the spot rate), making it more costly overall. Many banks like Taiwan Bank and Mega Bank offer free counter service fees, but others like E.SUN and Taipei Fubon charge 100-200 TWD per transaction.

Advantages: safe, full denominations, assistance from staff
Disadvantages: worst exchange rate, limited business hours (9:00-15:30 on weekdays), possible additional fees
Estimated cost: about 1,500-2,000 TWD loss on 50,000 TWD
Suitable for: seniors or beginners unfamiliar with online procedures, small amounts for urgent airport needs

Option 3: Online exchange + in-branch cash pickup—balanced choice

Using bank’s website or app to convert TWD to JPY at the “spot sell rate” (about 1% better than cash selling rate), then depositing into a foreign currency account. If cash is needed, it can be withdrawn in-branch or via ATM, but with a currency conversion fee (starting around 100 TWD). E.SUN Bank offers this service with favorable rates but requires opening a foreign currency account first.

This method suits those monitoring exchange rates, entering in batches when the rate is low (e.g., TWD/JPY below 4.80). Many investors use this to accumulate JPY and then invest in JPY fixed deposits (currently around 1.6% annual interest).

Advantages: 24/7 operation, ability to average costs over multiple purchases, better rates
Disadvantages: need to open a foreign currency account first, withdrawal incurs additional fee
Estimated cost: about 500-1,000 TWD loss on 50,000 TWD
Suitable for: experienced forex traders, regular foreign currency account users, planning to invest in JPY deposits

Option 4: Online currency exchange + airport pickup—traveler’s favorite

No need for a foreign currency account, just fill in currency, amount, pickup branch, and date online. After completing the transfer, bring ID and transaction notification to pick up in person. Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (only 10 TWD if paid via TaiwanPay), with about 0.5% favorable exchange rate.

This is the best pre-departure booking method, especially at Taoyuan Airport where Taiwan Bank has 14 branches (2 open 24 hours). Mega Bank also offers similar services with appointment options for airport branch pickup.

Advantages: favorable rates, often no handling fee, can choose airport pickup
Disadvantages: requires prior reservation (1-3 days), pickup during bank hours, branch cannot be changed
Estimated cost: about 300-800 TWD loss on 50,000 TWD
Suitable for: planned travelers, those wanting to pick up cash directly at the airport

Example costs for exchanging 100,000 JPY

Based on calculations for each method, the TWD cost of 100,000 JPY at different channels (using December 2025 rates):

• In-branch cash: about 20,600-20,800 TWD (highest loss)
• Online exchange + pickup: about 20,500-20,700 TWD (moderate loss)
• Online exchange + airport pickup: about 20,450-20,600 TWD (less loss)
• Foreign currency ATM: about 20,500-20,650 TWD (depending on cross-bank fees)

The difference can reach up to 400 TWD, which is significant for large exchanges (over 500,000 TWD).

Is it worthwhile to exchange for JPY now?

As of December 10, 2025, the TWD/JPY rate is about 4.85, compared to 4.46 at the start of the year, representing an appreciation of approximately 8.7%. Under the pressure of TWD depreciation, the exchange gains from JPY are quite substantial.

However, the yen remains volatile. USD/JPY has fallen from a high of 160 at the start of the year to around 154.58 now, with short-term fluctuations possibly returning to 155, but a medium- to long-term forecast suggests below 150. The BOJ’s rate hike supports the yen, but global arbitrage unwinding or geopolitical conflicts (Taiwan Strait/Middle East) could suppress it.

Advice: stagger your exchanges to avoid converting all at once. For investment purposes, JPY as a major safe-haven currency can hedge against Taiwan stock market volatility, but short-term risks include arbitrage unwinding, with potential swings of 2-5%.

After exchanging for JPY: 4 ways to grow your money

Shift to stable income or growth investments—don’t let your money sit idle with no interest:

1. JPY fixed deposit: most stable, open with E.SUN or Taiwan Bank, starting from 10,000 JPY, annual interest 1.5-1.8%
2. JPY insurance policy: medium-term holding, Cathay or Fubon savings insurance, guaranteed interest 2-3%
3. JPY ETFs: growth-oriented, e.g., Yuanta 00675U tracking JPY index, buy fractional shares via broker app, suitable for dollar-cost averaging
4. Forex trading: directly trade USD/JPY or EUR/JPY, long and short positions, 24-hour trading, small capital required but higher risk

Quick FAQs

Q. What’s the difference between cash exchange rate and spot rate?

Cash rate applies to physical cash transactions, with higher risk for banks, so the rate is usually 1-2% worse than the spot rate. Spot rate is used for electronic transfers and T+2 settlement, close to international market prices, more favorable. Simply put, cash exchange is more expensive, electronic is cheaper.

Q. What should I bring to exchange 100,000 JPY?

For in-branch cash exchange, locals need ID card + passport; foreigners need passport + residence permit. For online booking, also bring transaction notification. Large amounts (over 100,000 TWD) may require source of funds declaration. Minors under 20 need parental accompaniment.

Q. What’s the daily withdrawal limit at foreign currency ATMs?

Post-2025, many banks have adjusted limits. CTBC Bank’s card limit is equivalent to 120,000 TWD per day; Taishin Bank’s is 150,000 TWD; E.SUN Bank’s own card is 150,000 TWD daily. Consider spreading withdrawals or using your own bank card to avoid cross-bank fees.

Summary

The yen is no longer just “pocket money” for travel; it’s an asset with hedging and investment value. When exchanging JPY, choosing the right channel is key—if you have time, use online exchange and airport pickup; for urgent needs, rely on foreign currency ATMs; for small investments, do batch online exchanges. The amount of 100,000 JPY in TWD depends not only on the rate but also on your chosen method, with differences up to 400 TWD.

Follow the two principles of “staggered exchange” and “don’t leave your money idle after exchanging,” to minimize costs and channel your JPY into fixed deposits, ETFs, or swing trading, achieving multiple growth opportunities. Whether for travel or market hedging, yen can be a smart addition to your asset allocation.
