Basically the only thing you have to do in Japanese is find the book and put the book in the cart (green button that says カートに入れる). Then go to the cart (カート, shopping cart-shaped button toward the top right) - once you go into the cart, there a button at the top right for language, so you can switch the checkout/payment screens to English. If you don’t have an account already, the account creation/sign-in pages can be switched to English too, it seems.
In terms of finding the book to read (once you’ve bought it), you just have to click the gear button (マイページ) at the top right (then you can switch to English again and go to My Library -> find book and hit この本を読む).
I think I’m actually going to try e-reading for this one too :o
Because the thought of adding another physical book to my already-overflowing bookshelf of unread Japanese (and English) books is giving me weird anxiety ahaha I’m never going to finish all of these ><
Went to Book Off. No luck there although all the manga tended to be either 100 yen or “reduced” and in not much of an order so I spent a while there and because everything was so cheap it was tempting to buy a lot (which I did but at 100 yen why not?)
The Book Off I went to didn’t have any labels to distinguish which section you were looking at other than “100円” and "レディウス”.
Kinokuniya on the other hand had the 青年 section clearly labeled with the publisher. Found ゆるキャン easily there.
You mean レディース? that’s the woman equivalent of 青年. It would be very strange for a bookoff to not have 少年 and 青年 sections. They can be hard to find, though. When trying to find flying witch, I had to ask where the 少年 section was, cause I couldn’t find it. Turns out it was on a different floor.
When you can’t find, the best option is always to ask.
