Iām not going to be too much help here, since Iām actually not a fan of Apple, so I donāt 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 Iām not certain what issues youāve 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 donāt 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, canāt 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 donāt use the app. I use the website: amazon.jp
That might be the issue. The apps are geolocked for purchases, Iām 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 couldnāt solve nothing 
A VPN might help, yes. Iāve had to use one once or twice, and then never again. Lol
Just downloaded a VPN, Iām downloading books without problems from the apple books app (just bought éŖå½) but on the amazon kindle app I still canāt buy stuff, so weirdā¦
By the way, since Iām using a free trial and will have access to the vpn for a short period of time, does anyone have books suggestions? 
Edit: Iām 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 nowā¦ only thing is, there are only japanese subtitles so Iām 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 donāt have a lot of experience with apple as I donāt use apple eitherā¦ but I did use bookwalker.jp to buy a bunch of stuff (honestly I already own)ā¦so I had something to read in Japan on my tabletā¦was 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 couldnāt buy outside of Japan which I thought was strangeā¦ VPN to Japan and then I could buy them, but then I had to pay taxes on them lolā¦but it worked and now that I have them donāt 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) ā¦
But you do recall correctlyā¦I 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 bsā¦I 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 copyingā¦ very annoying when you just wanna hand over money and readā¦hence a paper copy wonāt let you down (especially when kindle or bookwalker change names or the servers disappear or what notā¦ 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? Iām seeing the prices and stuff looks as convenient as ever, just bought a nobel prize awarded book for 2 eurosš¤Æ 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) IIRCā¦was last sep/oct donāt remember but I do remember the prices of the other books when I went by VPN taxes were tacked on (Japan taxes)ā¦not US taxesā¦
yeah shipping takes time but I usually order from CDJapan and with DHL to LA is usually less than a weekā¦and with the time travel factor ā¦ itās sometimes 3 days ā¦ quick and convenient ā¦(no import taxes unless the value is above some very high number maybe 800 usdā¦donāt recall, havenāt ever hit that threshold )ā¦ not sure about how all that works in Europeā¦know the taxes and what not are different over thereā¦
Editābooks ā¦ hmā¦
if you want a bookclub book that already has vocab and past threadsā¦
You could go with é儳ć®å®
ę„ä¾æ (Kikiās Delivery Service)
or something similar * é§ć®ćććć®ćµćććŖēŗ (The Mysterious Town Beyond the Mist)
thereās also : * å¤ć«ćć§ (Night Cafe)
might want to check out this thread:
Alternatively there is GJBu and there are some books that have 5 min stories in themā¦ (will take you more than 5 min) but browse aroundā¦Iām sure youāll 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 donāt have a book club as well (not that I improved at japanese, I just got braver)
thatās the purpose will give a check to your suggestions, thanks!
foolish mortalā¦weāve all been thereā¦then you hit that wall at 100mph lolā¦ realize you know nothingā¦japanese is so āniceā that wayā¦good luck!!!
At the moment Iām running toward that wall at full speed with a big smile and a lot of enthusiasm
hmmā¦I dontā think I bought them in the appā¦IIRC I bought them through the web and then logged into the app to readā¦but this is getting outside of my realm of being able to helpā¦
try using the web browserā¦as 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 ā¦ so while you are waiting for your new order you have plenty of backlogā¦
I think yamamoto tsunetomo suggests doing something along those lines in Hagakure
It shouldnāt be Chinese by default, no. I have only ever used it in JP or English. But I alsp donāt 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. Youāll still want to make sure you have a (fake) Japanese address associated with the JP account, or it wonāt work.
Sounds like you got Apple working fine for you, though.
