Avoid APA at all costs, especially outside touristic areas. APA is used by everyone for all things, legal or not, and the state of your room may vary wildly.
I'm from the UK where even a crap hotel costs $80-100/night, so being able to pay under $40 for the quality APA provides (even if the rooms are small) is insane to me.
Meaning the ones used by drunks, drug addicts, and prostitutes.
APA does not provide top notch maintenance for its hotels in Kiyosumi-Shirakawa, Nishi Kasai, Meidaimae, or any non important area.
If you stay in the hotel close to the central station of a small town - that's touristic. Japanese tourists are staying there.
What I mean is that APA is really bad off the beaten path, and since the article recommends branching off, using APA is a very bad idea.
Other major business hotel chains:
* Toyoko Inn
* Dormy Inn (almost always has a bath on the top floor!)
* Candeo hotels (same!)
* M's hotels (there are many variations on the "M's" name)
* Unizo
* Smile hotel
* Hotel mystays
* Hotel livemax
* Daiwa Roynet
...and tons of others that are less universal. While there are subtle differences between them (e.g. some have better beds, others have laundry facilities, some have public baths on the top floor), virtually all "business hotels" have the same set of features, down to the layout of the rooms, and can usually be had for $50-$100 a night. That said, they are small, and you will not be happy if you're the kind of tourist who lugs multiple large suitcases everywhere you go, or if you're seeking a "luxury" experience.
Business hotels are cheap places to crash for a night and little more.
Although it is true that Japan is a bit of a struggle if you are overweight or especially tall.
It's more that Japan (and many other places) have a product class at a pricing point that Americans do not so Americans think they've gotten a great deal but instead it's a product they're not expecting and not familiar with.
Maybe you want that, just know what you're buying.
Also, this list specifically recommends the APA hotel chain, whose president leaves copies of his revisionist history book denying the Nanking Massacre in their hotel rooms, often in foreign languages[1]. There are quite a few nationwide hotel chains in Japan like Dormy Inn and JR METS as well as thousands of independents, most of which are listed on price comparison websites and will come in around the same cost as a room at APA. Please consider supporting another hotel, ideally a local one, before APA :)
