Agreement with Rakuten

Boku (AIM: BOKU), the world's leading independent direct carrier billing company, is pleased to announce it has signed an initial deal with Rakuten Collection, a division of the Rakuten Group, to provide carrier billing solutions for Rakuten Collection's e-commerce site, focused on the Japanese market. This is Boku's first major agreement to provide carrier billing services for physical eCommerce in Japan.

Rakuten Collection is an e-Commerce site that specializes in the sale of limited edition, collectible trading items that are popular in Japan. Boku's carrier billing service was recently activated for Rakuten Collection and the two companies are now exploring ways to expand Boku's service to other Rakuten offerings. Rakuten operates over 70 services including Rakuten Ichiba (eCommerce shopping mall), Rakuten Kobo (eBooks), Rakuten TV (streaming video), and Rakuten Travel (travel bookings).

Jon Prideaux, CEO of Boku Inc., commented: "Japan is a very exciting territory for us because it offers the unique opportunity to expand carrier billing into any eCommerce channel including those that sell physical goods. Rakuten is one of the top two eCommerce operators in Japan and we intend to work closely with them to offer more of its customers the option of charging any Rakuten purchase to their mobile phone bill."
