There are several possibilities for you to set one up- depending on the visa you are in Japan with, as well as your Japanese language abilities. As a tourist it seems to be impossible though.
Why would you need a bank account?
What do you need to apply for a bank account?
Which banks are best?
From experience we know that many Japanese banks do refuse foreign customers for several reasons, mainly visa- or language ability related. The friendliest are those two:
The Japanese Post Bank Yûchoginkô ゆうちょ銀行 is very friendly and even with a Working Holiday Visa it is rather easy to set up a bank account. You find it within the post offices.
Mitsui Sumitomo Bank Mitsuisumitomoginkô 三井住友銀行seems foreigner friendly, but you must speak and write Japanese enough to be able to understand the staff and fill the forms correctly. The big ones in the main tourist areas also provide a currency exchange service. The one in the pictures is right at Kaminarimon in Asakusa.
Beware, some while ago a new rule had been established. One is that transferring money from abroad to Japan or the other way around will not be allowed until you are here for 6 months already, but you may set up a bank account right on the day you are arriving in Japan if you are not on a tourist visa. Ask the bank if you can do transfers within Japan already.
The most important vocabulary concerning banks:
