Japanese Yen Exchange Practical Guide: Breakdown of 4 Major Options and the Best Timing

The NT$ to JPY exchange rate has reached 4.85 (December 2025). The surge in travel demand to Japan and the dual need for JPY hedging have driven the currency exchange market to heat up. But did you know? Choosing the wrong channel for exchanging JPY can result in a loss of over NT$1,500 just from the exchange rate difference.

This article compares the most practical 4 JPY exchange paths in terms of cost, time, and flexibility, helping you find the most suitable solution.

Why is now a good time to exchange JPY?

Surge in travel and lifestyle needs

Japan’s consumption still relies mainly on cash, with only about 60% credit card penetration. Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, cash demand is urgent. Plus, scenarios like purchasing agents, online shopping from Japan, and studying abroad have made exchanging JPY a daily financial need for Taiwanese.

Dual value as hedging assets

The Japanese yen is one of the world’s three major safe-haven currencies alongside the USD and Swiss Franc. Taiwanese investors can allocate JPY to hedge against Taiwan stock market fluctuations. For example, during the Russia-Ukraine conflict in 2022, when the stock market fell 10%, the yen appreciated 8%, effectively buffering portfolio losses.

Additionally, the Bank of Japan’s rate hike expectations are heating up (Governor Ueda Kazuo is expected to raise rates to 0.75% at the December 19 meeting, a 30-year high), indicating a clear long-term strengthening trend for the yen. Since the beginning of the year, the NT$ to JPY has appreciated 8.7% (from 4.46 to 4.85), offering considerable exchange gains for investors.

Clear explanation: Cash rate vs. Spot rate

Before diving into the 4 exchange options, two core concepts must be understood.

Cash Rate is the buy/sell rate banks offer for physical banknotes, usually 1-2% worse than the market spot rate. The advantage is immediate cash receipt; the downside is the highest cost.

Spot Rate is used for electronic transfers, settled within T+2, closer to international market prices, with lower costs. But it requires waiting for settlement.

Understanding this difference helps determine when to use cash and when to opt for account transfers.

4 Major JPY exchange paths: Cost and time comparison

Option 4: Online exchange + foreign currency account (investment-oriented)

This method is best for monitoring exchange rates, entering gradually at low points (e.g., NT$ to JPY below 4.80). Yushan Bank app offers exchange, with withdrawal fees equal to the rate difference, minimum NT$100.

Next steps for JPY asset allocation

After exchanging JPY, don’t let your money sit idle without interest. Here are 4 options suitable for small-scale beginners to build a steady portfolio:
