I thought about sending a fake ID, but I don't want any bullcrap with my own government coming back to me. Seems like this affects all Japanese forwarding services and all purchases. I have not seen any sites like P-4 doing this. That would suck hard.
I have sent them another disgruntled long winded email reply saying that I have complied with their requests as CLEARLY stated in several places on their web site in the form of a Certificate of Employment. Not really an official document, but again they don't need my ID to send me a frikking TOY. I am not a criminal.
From 1st April 2013 Japanese law has changed to require all forwarding companies such as Tenso.com to obtain proof of identity from their users. The legislation detailing these changes is known as the 'Prevention of Transfer of Criminal Proceeds'. More details are available on the National Police Agency website. http://www.npa.go.jp/sosikihanzai/jafic/index_e.htm
In order to continue to use forwarding services such as Tenso.com, you must submit a form of personal identification which shows your [ Name ], [ Date of Birth } and [ Current Address ]. Please submit a copy of your government-issued identification, such as a Passport, Driver's License, Certificate of Employment, National ID Card (etc.)
