Just for your information I contacted the FCC Wireless Bureau and the ITU. If you attempt to bring two way radios of any kind into Japan without a license you will be imprisoned by the JARL report. Also if you attempt to bring any radio in not authorized in their frequency band (GMRS and FRS are not) you must have a permissable purpose. ie. transporting them to a manufacturering or servicing facility for service or repair is the only one that you could use. If you transmit on the radios, the minimum penalty is 90 days in jail and 100,000y. I don't know if this a lot or not today but it is too much for a penalty of this kind.
