Hoshi is also used as a masculine name in Japanese. However, it's more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine". Some evidence for this is that Hoshi is also used as a name element in unisex and masculine Japanese names, such as Hoshihiko, Hoshihito, Hoshiki, etc.Sources: https://en.m.wikipedia.org/wiki/Hoshi (I think) https://forebears.io/x/forenames/hoshi
