日本經濟自1990年起，由「日本第一」落入「流動性陷阱」，而陷入長達10多年的不景氣，主因是日本股市及不動產市場重挫，企業向銀行貸款所提供之擔保品價值下滑，卻因在低利率時代已過度借貸，又經營不善面臨虧損，發生償債困難，一旦財務有所改善，只想提前償還貸款，而無增加貸款意願，故稱為「資產負債表的衰退」（Balance Sheet Recession）。整體經濟景氣蕭條，國內需求不振，亦使振興經濟之寬鬆貨幣政策無法達到預期效果。
日本資產泡沫的破滅使銀行體系的逾放問題日益嚴重。日本政府為了加強銀行體系的健全性，實施金融改革（Big Bang）。使原本以傳統存、放款業務為主的銀行，在面臨國際化浪潮時，也能同時經營證券、保險業務，並將新金融商品引進日本。並由隸屬於內閣府的金融廳(Financial Services Agency)來監督日本銀行及證券業務，負責金融檢查及金融法規企劃業務，落實金融與財政分離之原則。但日本金融業務日益多元化，及衍生性金融商品日趨複雜，對金融監理機關之專業能力，形成新的挑戰。以上所述為日本國內的經濟與金融問題。
至於日圓對外幣的匯率方面，由於日圓利率偏低，套利交易(carry trade) 盛行。投資人趁著日本央行維持低利率之際，借入低成本的日圓資金，然後換成利率較高的外幣轉戰國際市場，追逐收益較高的資產，同時賺取利差、匯率及資產升值的價差，使日圓匯率的走勢疲弱，也造成全球金融市場的波動。

Due to the stock market and real estate market plunge, the deep recession has lasted for over 10 years. The bursting of asset bubbles caused the balance sheets of enterprises to become weaker and weaker. All companies hoped to reduce their debt to banks if they were profitable. They had no intention to reinvest any more. So it was called - Balance Sheet Recession.
Even though the Bank of Japan adopted an easy monetary policy, the financial system remained vulnerable. With the bad debt of commercial banks increasing, the NPL (non-performing loan) problem has been a major concern for city banks and regional banks.
Japan's "Big Bang" reforms radically altered its financial marketplace. The barriers separating banks, securities, and insurance companies were lowered. The Financial Services Agency replaced Ministry of Finance to oversee banking, securities and exchange and insurance in order to ensure the stability of the financial system. As for financial business diversified and derivative products complicated, there were many great challenges facing the financial regulatory authorities.
During the past decade, the yen carry trade has become a target for many investors or speculators. Traders using this strategy attempt to capture the difference between the interest rates of two currencies. Taking USD/Yen for example, they borrowed the cheaper yen and invested in U.S. Treasuries yielding a higher interest rate. It causes the depreciation of Japanese Yen and increases the volatility of financial markets.
This essay describes Japanese financial crisis, Japanese monetary policy, stock market, and real estate market. Besides, I analyze the profitability, capital adequacy, and non-performing problems of Japanese banks. Finally, I give my personal opinions on Taiwan and Japan’s banking industry.
