Iâm not going to be too much help here, since Iâm actually not a fan of Apple, so I donât use any of their devices. 
But I would guess that there moght be a Bookwalker app, and you could just purchase through bookwalker. Kindle app is probably a thing too, to keep the same purchase ecosystem, but Iâm not certain what issues youâve been running into on there. I could probably walk you through that, at least, since kindle is the only thing I use.
I would love to do everything in my kindle app but seems impossible, I tried everything 
let me explain the issues.
I tried purchasing in my kindle app from ipad but it tells me that I cannot buy from the app for some reasons:
So I went on the amazon app, where there is the same message:
At this point, after spending several hours trying to get back into my japanese account, I make it and try to order the books but it very weird: I donât just buy the kindle copy with a quick payment as for everything I buy on amazon, I simply create an order (of the kindle copy) that remains awaiting for forever. (Ordered Hagakure 2 weeks ago and still waiting, canât find out why, not used to the japanese amazon)
I begun losing hope, but I try my last card: buying on Kindle. Except that suddenly I receive a message from my bank app, telling me that the payment is not authorized. I tried fifteen times and different fixes but nothing works, do you know how to do it?
I donât use the app. I use the website: amazon.jp
That might be the issue. The apps are geolocked for purchases, Iâm fairly sure.
Do you mean that through a VPN I may be able to bypass the problem?
Anyway, the last part of what I wrote, I did on website (still on iPad tho), but couldnât solve nothing 
A VPN might help, yes. Iâve had to use one once or twice, and then never again. Lol
Just downloaded a VPN, Iâm downloading books without problems from the apple books app (just bought éȘćœ) but on the amazon kindle app I still canât buy stuff, so weirdâŠ
By the way, since Iâm using a free trial and will have access to the vpn for a short period of time, does anyone have books suggestions? 
Edit: Iâm exploring the world from VPN and I love it, I think I will get the yearly subscription. Japanese netflix is incredible, I think I can get rid of crunchyroll now⊠only thing is, there are only japanese subtitles so Iâm considering of embarking in a suicidal mission: only watch content with jap subtitles. Considering how few of everything I understand atm, would you guys think this may be productive or I better wait to improve?
So donât have a lot of experience with apple as I donât use apple either⊠but I did use bookwalker.jp to buy a bunch of stuff (honestly I already own)âŠso I had something to read in Japan on my tabletâŠwas going to carry the physical copies but being there for a month and luggage space just gave bookwalker more money. The tablet is a Samsung and works fine with bookwalker.
However, I did find there were a couple of books that I couldnât buy outside of Japan which I thought was strange⊠VPN to Japan and then I could buy them, but then I had to pay taxes on them lolâŠbut it worked and now that I have them donât need the VPN to read them. The upside of the bookwalker app is I can use it on my phone or tablet and it works fine. Just make sure that you are logging into the bwjp vs bw us (or other country) âŠ
But you do recall correctlyâŠI do still prefer paper and I just read the first ch of vol 12 so I could click that button @anon99047008 
The upside of paper is none of that DRM bsâŠI just want to be able to buy it and read it FFS
I am fully convinced all that DRM copy crap and greedy licensing controls just further encourages more illegal copying⊠very annoying when you just wanna hand over money and readâŠhence a paper copy wonât let you down (especially when kindle or bookwalker change names or the servers disappear or what not⊠you still have the book right!)
This is true but still requires to get the product shipped so it takes more time.. what taxes do you refer to? Iâm seeing the prices and stuff looks as convenient as ever, just bought a nobel prize awarded book for 2 eurosđ€Ż also, do you have any book recommendation (book or LN that I can buy on apple books, not manga)?
so buying the e-version there was no sales tax in japan when buying from the US (non-vpn) IIRCâŠwas last sep/oct donât remember but I do remember the prices of the other books when I went by VPN taxes were tacked on (Japan taxes)âŠnot US taxesâŠ
yeah shipping takes time but I usually order from CDJapan and with DHL to LA is usually less than a weekâŠand with the time travel factor ⊠itâs sometimes 3 days ⊠quick and convenient âŠ(no import taxes unless the value is above some very high number maybe 800 usdâŠdonât recall, havenât ever hit that threshold )⊠not sure about how all that works in EuropeâŠknow the taxes and what not are different over thereâŠ
Editâbooks ⊠hmâŠ
if you want a bookclub book that already has vocab and past threadsâŠ
You could go with éć„łăźćź
æ„äŸż (Kikiâs Delivery Service)
or something similar * é§ăźăăăăźă”ăăăȘçș (The Mysterious Town Beyond the Mist)
thereâs also : * ć€ă«ă㧠(Night Cafe)
might want to check out this thread:
Alternatively there is GJBu and there are some books that have 5 min stories in them⊠(will take you more than 5 min) but browse aroundâŠIâm sure youâll find plenty of easy ways to part with that cash haha
utopia fo me, i think to get takagi-san vol 1-6 i waited 2 weeks (was actually happy about how fast they were)
sorry forgot to answer your questions about books - edited the previous post for you
Well at this point nothing scares me so I would adventure in books that donât have a book club as well (not that I improved at japanese, I just got braver)
thatâs the purpose will give a check to your suggestions, thanks!
foolish mortalâŠweâve all been thereâŠthen you hit that wall at 100mph lol⊠realize you know nothingâŠjapanese is so âniceâ that wayâŠgood luck!!!
At the moment Iâm running toward that wall at full speed with a big smile and a lot of enthusiasm
hmmâŠI dontâ think I bought them in the appâŠIIRC I bought them through the web and then logged into the app to readâŠbut this is getting outside of my realm of being able to helpâŠ
try using the web browserâŠas long as you do the e-book you should be able to read in a browser or app.
I may as well go back to paper
or the trick is to buy more than you can read ⊠so while you are waiting for your new order you have plenty of backlogâŠ
I think yamamoto tsunetomo suggests doing something along those lines in Hagakure
It shouldnât be Chinese by default, no. I have only ever used it in JP or English. But I alsp donât buy from it that often. It just has a better interface than Amazon for seeing what is free, so I use it to see what things are free and then go download it from Amazon.
@ChristopherFritz would be the better guide for Bookwalker.
To clarify, though, when using the VPN for Amazon, I still had to go to the actual website. Youâll still want to make sure you have a (fake) Japanese address associated with the JP account, or it wonât work.
Sounds like you got Apple working fine for you, though.
