From now on you can purchase Hatena Color Stars with Rixty, the leading cash-based payment platform for games and digital content.
Please note it will remain possible to purchase subscriptions to Flipnote Hatena Plus by credit card after May 31, 2012.

We look forward to your continued enjoyment of Hatena's online services.
