bk1 decided to merge with honto. If you were a previous customer of bk1, all your points and past orders can be moved over to honto as well. In order for that to happen though, you would have to log in to honto with your old bk1 account information. For those who don’t know how to do it, refer to this picture of the login page:
Once you log in, it would ask you to confirm your information to register with honto. After registering with honto, you would not be able to log in from the bk1 section (on the left side of the login page). Instead, you would login as a honto member (on the right side) using your bk1 login information (same email/password).
honto has a different interface than bk1. the merge gives bk1 a more competitive edge to other online bookstores like amazon.
They have more personalized customer pages. For example, on マイページ (My Page), they have a マイ本棚 (My Shelf), where they put all your previous orders’ books into a bookshelf for you to view. You won’t have to look at your own bookshelf at home to see if you own the book already or not… 便利. Lots of other cool things too. Please check it out if you haven’t yet.
They currently have a campaign running from 5/17 until 6/19. If you buy anything from honto, you would get 3x the points. More information can be found here (in Japanese).
