Hi!
All of the old Japanese banknotes issued since the end of World War II are still valid and redeemable at the Bank of Japan. That is my understanding.
The only catch is that you have to be present at the counter at the Bank of Japan or appoint someone to be your agent to exchange the old notes there.
That is my problem right now because I have a tidy amount of old Japanese banknotes that I would like to exchange. But I could not because I am not in Japan or know anyone in Japan who could assist me in exchanging them.
If you have any good suggestion or helpful advice, it would be greatly appreciated!
Thanks!
Nekosasori,
Since you are based in Ireland, I think you should exchange your Japanese banknotes at the banks for euros. Otherwise, they will not exchange "old" banknotes for you because they are not the Bank of Japan.
Or you can always hold onto your Japanese notes until you return to Japan. Then, you can go to the Bank of Japan to exchange them.
Good luck!
