You will be able to find ATMs everywhere including in a post office and a convenience store, so you probably wouldn’t need to go to a bank at all during your stay in Japan. The Bank of Tokyo-Mitsubishi UFJ is the largest bank in Japan. Its head office is in Marunouchi business district in Central Tokyo. In addition, there are several different banking systems, such as Development Bank of Japan (DBJ) and ‘Net Bank’. DBJ provides investment, loan and advisory services both domestically and internationally. ‘Net Bank’ is a new form of Internet banking or direct banking in Japan, which basically operates online or telephone banking without having a physical bank.
