Bookwalker good for access to manga in Japanese?

tl;dr: Is Book Walker a good, legit way to get access to manga in Japanese? Are you able to use their JP app from outside the country? What do you use instead, if not?

I've started reading super easy manga in Japanese, so I've been looking to get more access to manga. I see a few stores in my country that sell them like Kinokuniya. But I'm looking for virtual options, mostly because of space and availability.

After researching, I found lots of recommendations for Book Walker, specifically the JP store. From what I understand from their terms and service, it's ok to have an overseas account, and they'll restrict a few titles based on regional availability. That's totally fine by me, lots of good titles are still available. Decided to test it by reading あしたは土曜日 and it's working well, but I'm not a huge fan of their browser experience. It's manageable tho.

So before going deeper, I thought I'd ask here to see what others have tried and seek advice!
