Why the Yen Is Plunging and What It Means for Japan Travel

South Korean tourism to Japan is increasing as the Japanese yen has fallen to the 800-won range for the first time in 20 months, according to a July 27, 2026, report from Daum. The currency devaluation has lowered travel costs for Korean visitors, leading to a surge in crowds at major Japanese tourist destinations during the summer vacation period.

Yen Exchange Rate Hits 20-Month Low

The exchange rate for the Japanese yen has dropped to the 800-won level, a valuation not seen in approximately one year and eight months. This shift has made Japan a primary target for South Korean travelers seeking affordable international trips during the 2026 summer season, as noted by Daum.

The lower cost of the yen relative to the Korean won reduces the price of accommodation, dining, and shopping for visitors. This economic incentive has resulted in a visible increase in the number of South Koreans visiting cities such as Tokyo, where travelers are choosing the destination specifically due to the favorable exchange rates.

Drivers of Yen Weakness

The continued weakness of the yen is tied to the divergence in monetary policy between the Bank of Japan and other global central banks. While many nations raised interest rates to combat inflation, Japan maintained a low-interest-rate environment for a longer period, which typically weakens a currency’s value on the global market.

This gap in interest rates encourages investors to move capital out of yen-denominated assets and into currencies with higher yields, such as the U.S. dollar. The resulting selling pressure keeps the yen suppressed, which in turn lowers the cost for foreign tourists entering the Japanese economy.

Impact on Japanese Tourism Sector

Japanese tourist sites are experiencing a significant influx of Korean visitors. The combination of the 800-won exchange rate and the timing of summer holidays has concentrated this growth in high-traffic urban areas and popular regional attractions.

The surge in visitors provides a boost to local businesses, including hotels and retail stores, though it can lead to increased congestion at major landmarks. The trend reflects a broader pattern where currency fluctuations directly dictate the flow of short-haul international travel between South Korea and Japan.
