Is there any currency exchange shop in Japan who can accept exchanging SAR to YEN‏

Hi,

I’m contacting you in regard of getting help from you about currency exchange shops. I’m from Saudi Arabia and the currency I’ve with me is the Saudi Arabian Riyal [SAR] I found out that all the currency exchange shops I went to in Tokyo and Osaka don’t accept SAR so I would like to know if there’s any currency exchange shops you know who can accept exchanging SAR to YEN.

Regards
