Abstract: 1. The economies of Japan and South Korea are dominated by banks. 2. This study aims to identify and assess the health of domestic banks in Japan and South Korea for the Covid-19 ex-ante and interim periods. 3. Japanese banks are divided into four clusters, i.e., City Banks, Regional Banks I, Regional Banks II, and Trust Banks. 4. Throughout the timeframe of our investigation, the BOJ and BOK de-ployed monetary policy measures to influence bank conditions. 5. Figures show that the total assets of Japanese banks increased continu-ously, albeit at varied rates, from 2010 to 2019, never falling below 2 per-cent. The increase in bank loan amounts, from ¥8 trillion in 2012 to ¥543.9 trillion in 2021, explains some of the banks’ asset expansion. 6. Japanese banks had relatively low net earnings against their assets in terms of productivity, resulting in a poor return on assets (ROA). 7. Japanese banks’ ordinary profits peaked at 7.39 percent in 2014 and have steadily declined. However, the operational profit data from 2015 to 2020 has formed a U-shaped curve, indicating recent improvement. At the same time, banks' net incomes were significantly lower than their op-erating profits. 8. The efficiency of Japanese banks has remained low for a long time. From 2011 to 2021, none of the Japanese bank clusters met even the less strict efficiency standard of 60%. Even though Covid-19 might the-oretically cut operational expenses, Japanese banks’ overall efficiency ra-tio in 2021 was 83.9 percent. We are constrained by the Korean banks’ operational efficiency data. However, available data for 2020, the year of the COVID-19 outbreak, shows that most of them maintained an effi-ciency ratio of 60% or less. 9. Since 2012, Japanese banks have reduced the percentage of non-performing loans to total loans. Between 2012 and 2020, however, the ratio fell from 2.4 to 1.1 percent. Due to Covid-19, the NPL ratio went marginally up to 1.2 percent in 2021. At the same time, Korean banks had significantly lower NPL ratios than Japanese banks. All banks’ total NPL was 0.25 percent of their loans in 2020. 10. Despite their differences, the study revealed that Korean domestic banks could sustain better health indicators than their Japanese counterparts for much of the study period. Banks in Japan are trying to maintain bet-ter financial health with the ultra-low interest rates imposed by the QE-2 monetary policy. During Covid-19, the profitability and efficiency of the sector have been adversely affected.
