The Japanese yen (JPY) is one of the most widely traded currencies in the world, serving as a key player in international finance and global trade. Like all currencies, its value fluctuates based on various economic and geopolitical factors. But what exactly does it mean when people say the yen is “strong” or “weak”? And how does that affect travelers, businesses, and the global economy?
This guide provides a detailed yet easy-to-understand explanation of what a strong or weak yen means, how it’s measured, what influences its movement, and how it impacts different groups—from tourists to investors.
Understanding Currency Strength
What Does “Strong” Mean?
A strong yen refers to a situation in which the value of the Japanese yen rises relative to other currencies, especially the U.S. dollar (USD), euro (EUR), or Chinese yuan (CNY). This means:
- You get more foreign currency when exchanging yen.
- It costs less for Japanese consumers and businesses to import goods.
- It costs more for foreigners to buy Japanese goods and services.
For example, if the exchange rate shifts from ¥150 to ¥100 per US dollar, the yen has strengthened.
What Does “Weak” Mean?
A weak yen is when the value of the yen drops compared to other currencies. In this case:
- You get less foreign currency when exchanging yen.
- Imported goods become more expensive in Japan.
- Japanese exports become cheaper and more attractive abroad.
If the rate changes from ¥100 to ¥150 per US dollar, the yen has weakened.
Measuring the Yen’s Strength
Exchange Rates as a Benchmark
The strength or weakness of the yen is typically measured using foreign exchange (forex) rates, such as:
- USD/JPY – The number of yen needed to buy one US dollar.
- EUR/JPY – The yen’s value against the euro.
- CNY/JPY – The yen compared to the Chinese yuan.
A lower number (e.g., ¥100 per $1) means the yen is stronger; a higher number (e.g., ¥150 per $1) means it’s weaker.
Real Effective Exchange Rate (REER)
The Real Effective Exchange Rate takes into account inflation and trade-weighted averages. It offers a more accurate long-term picture of the yen’s strength compared to just looking at bilateral rates.
Causes of a Strong or Weak Yen
Interest Rates and Central Bank Policy
The Bank of Japan (BOJ) plays a major role in the yen’s strength through monetary policy. For example:
- Low interest rates: Often lead to a weaker yen, as investors seek higher returns elsewhere.
- Rising interest rates: Can strengthen the yen by attracting more foreign capital.
In 2025, Japan’s central bank has begun slowly shifting from ultra-loose monetary policy, influencing the yen’s global performance.
Economic Performance
The yen reacts to key economic indicators such as:
- GDP growth
- Inflation rates
- Employment statistics
- Trade balances
A strong economy generally leads to a stronger yen, and vice versa.
Global Events and Investor Sentiment
Geopolitical stability, trade wars, pandemics, and financial crises can all affect the yen. Interestingly, during times of global turmoil, the yen often strengthens because it’s seen as a “safe-haven” currency.
Impact of a Strong Yen
Effects on Japanese Exports
A strong yen makes Japanese goods more expensive overseas. This can hurt manufacturers like Toyota, Sony, and Nintendo, which depend heavily on exports.
Benefits for Japanese Consumers
On the flip side, a strong yen makes imported goods—such as foreign food, fashion, and electronics—cheaper for Japanese consumers.
Travel and Tourism
A strong yen makes Japan more expensive for foreign tourists but makes overseas travel cheaper for Japanese residents.
Impact of a Weak Yen
Boost for Exporters
A weak yen is often good news for Japanese companies that export goods abroad. Their products become more competitively priced in global markets, boosting sales and profits.
Rising Import Costs
However, a weaker yen makes imported items—like oil, gas, and food—more expensive, which can lead to inflation within Japan.
Tourism Surge
For tourists, a weak yen means their dollars or euros go further in Japan, often resulting in a boom in international tourism.
Who Gains or Loses?
Winners When the Yen is Strong
- Japanese travelers going abroad
- Importers and consumers of foreign goods
- Investors holding assets denominated in foreign currencies
Losers When the Yen is Strong
- Japanese exporters and manufacturers
- Foreign tourists visiting Japan
- Domestic tourism and hospitality sectors
Winners When the Yen is Weak
- Export-driven companies
- Foreign tourists visiting Japan
- Domestic tourism and production-focused sectors
Losers When the Yen is Weak
- Japanese households (due to higher import prices)
- Travelers going abroad
- Companies relying heavily on imported materials

How This Affects Travelers in 2025
Real-World Impact on Tourists

Smart Traveler Tips
- Monitor exchange rates before booking your trip.
- Use international debit/credit cards that offer favorable forex rates.
- Convert small amounts at a time if the yen is highly volatile.
Investment and Financial Strategies
Hedging Against Currency Risk
Investors and multinational companies use financial instruments like:
- Forward contracts
- Currency swaps
- Forex options
These tools help protect against yen volatility, especially in uncertain economic times.
Investing in Japan During Currency Shifts
When the yen is weak, Japanese stocks become cheaper for foreign investors. On the flip side, repatriating profits in a strong-yen environment can increase returns.
Conclusion
The strength or weakness of the Japanese yen is more than just numbers on an exchange board—it influences international trade, investment flows, tourism trends, and the everyday lives of millions.
