Send the IPMO to:

Sanpei Shohji Company  
Postal Code 164
Take-mori Haitsu 102 
4-8-20, Chuhoh, Nakano-ku, Tokyo, Japan

and make out the IPMO to:

Sanpei Shohj Company 
Yamaoka Building 3F 
Kyoubashi 2-2-1 Chuhoh-Ku 
Tokyo, Japan 

I just received my last order fromn Mangaya, so I 
guess it worked OK.

Hope this helps.
