Can men also filter their search results by the number of stars?

Maezawa here—I’ll answer too. Since “rating (number of stars)” isn’t available as a search filter, you can’t narrow the results down that way. However, there is an option to sort by “highest-rated,” so if there are currently only a few highly rated women, you can still look for those with the best ratings. (There doesn’t seem to be an option to sort by lowest rating.) Looking at Nonta’s percentage of women rated four stars or higher, the figure is unusually low only in Tokyo, so it’s possible they’ve been slacking on updating the ratings. (We’d need to look into it properly to know for sure.) If they’re quick to lower ratings but don’t bother raising them, that’s a bit of a problem.
