I'm not very successful with Japanese women so probably not the best person to answer that question but for the sake of diversity maybe my answer might be worth something to the OP.
I have dated at least 60 girls in 5 years (that number comes from the fact that as far as I can remember not a month has gone by without at least one date). My success rate is rather low with Japanese women and high with other Asian nationalities (notably Chinese, Vietnamese and Filipinos) non-existent with Western women (our paths simply don't cross). I think my problem with Japanese women comes from the fact that I have difficulties adjusting to the tatemae culture and that I find it a lot harder being myself with them.
As for the kind of women I like: outspoken, with strong opinions (including political), curious about stuff slightly outside the mainstream (being a classical/avant-garde music and cinema buff, that's very important to me), DEFINITELY not into the kawai/anime/disney/J-K pop culture, with some interest in history and foreign cultures, ideally in her late 20's or early 30's (I'm 37), speaks at least some English (my Japanese is only average), is independent both emotionally and financially (not living with her parents), doesn't want to have children and is not obsessed with marriage and having me meet her parents. Better if she has her own friends and hobbies and is not relying on me being available 24/7 to entertain her. Weird but without any crippling mental illness. Physically, not too skinny and doesn't wear too much make-up.
Since I mostly rely on dating and conversation apps to meet women, my criteria are completely out of line with the kind of people you meet there so I'm not really holding my breath.
