looking for information from wheelchair using people who live here or have been here temporarily and can tell me what the biggest struggles were or what could be improved.

Most every time the Japanese-enrish phrase "バリアプリ/Barrier-Free" is used in Japan, it's a lie.

What Japanese mean is that a place has some half-assed consideration to accessibility...like a so-called "wheelchair ramp" that ends in three stair steps.

"biggest struggles"???

On-site building/construction inspection for accessibility is zero, as is any testing of the accessibility provisions (which never fully work). All Japanese building inspectors (may they all burn in Hell) do is rubberstamp construction plans. Nobody checks if the faux barrier-free provisions actually work.
