Apparently Harper Collins used to make massive oversized books printed in English. I'm not sure if they sold them in Japan or if they were bought outside of Japan, but I haven't had much luck finding them locally (I'm far away from any major city) or online. I own two and I'm looking for more.
So far I have searched on Amazon (shipping directly to Japan) and Amazon.jp, as well as Merucari, AbeBooks and Englishbooks.jp. I haven't been able to find anything that matches the size of the books I own (appx 34cm by 46cm), and the books that I have found tend to max out at about 28cm or so.
Ideally, I'd like to find a few more of these books online, either new or used. I wonder if my search terms in English aren't getting any hits, particularly on Merucari. Whatever search terms I'm using in Japanese also don't seem to be getting me anywhere, but it's entirely possible that these books are not common in Japan.
Any leads on where to find these books or useful search terms in Japanese would be much very helpful!
