Note 2: The migration process has closed in May 2020 (or so).
Note 3: Japanese mobile numbers are now required if you wish to create a Yahoo! Japan account 😦 – I recommend checking BookWalker for international-friendly accessibility for manga in Japanese and English (global store).
I will go into detail about the merging of eBookJapan with Yahoo! Japan’s Bookstore (their ebook retail arm). Read it here.

Page 1 This page is for existing users. Read more after the cut.
Page 2 for creating a new account.
Page 3 is how to login on Android.
Page 4 is the out-of-date guide for the now defunct eBookJapan Initiative website.
Note: This post is heavy on graphics/screenshots.
This page is for existing users migrating from the old to the new site.
1. Go here to initiate the migration process.
You need to be logged in. Select the third and last button at the bottom of the page.
There’s a lot of graphics about their merging but go to the bottom.
I think most users would have a Yahoo! Japan account linked by now.
If you haven’t, go get it linked. (Check page 4 for more info.)
Reminder: It might be best to have an active credit card on file so it’ll be transferred to the new website. If you want to buy any released e-books, buy it before migrating your account. (Read more about purchasing e-books on the new app. Big thanks to @funkytachi!)
2. Then you’ll be brought to this page. Review your account info, make sure everything’s correct and press the big pink button at the bottom. You’ll be notified by email when the migration is done. (Though bookshelves would take some time to reflect on the new website.)
(Still under construction. I’m still in the process of migrating my account.)
