What is “Otsukai”?
If you want to buy Japanese anime goods or comics which you can get only in Japan, you can ask a Japanese member to purchase and send it to you through the Otsukai website.
When you’ve decided to purchase, your payment is sent to the Otsukai office via PayPal. Then Otsukai will pay to a Japanese member after the item has arrived.
A new user (Japanese people only) now gets an Amazon gift code
Now Otsukai holds a promotion campaign to increase Japanese members in the service. Probably, that will make interaction between users of the service more active.
