The yen's real effective exchange rate peaked in April 1995 at 193.95 and has since fallen to roughly a third of that level. The yen has weakened against a wide range of currencies, including the U.S. dollar and euro, as well as the Chinese yuan and Thai baht. One major factor is the prolonged slump in the Japanese economy, known as the "lost decades," following the collapse of the bubble economy. Japan's potential growth rate, which was around 1% in 1995, was stuck in the low-0% range in the late 2010s, according to the Bank of Japan. The weak growth potential led to extremely low inflation and interest rates, resulting in a prolonged decline in the real effective exchange rate. With both prices and wages rising recently, the BOJ is working to normalize monetary policy. The bank has indicated plans to continue raising the policy interest rate above the current 0.75%.
