Here are a few words related to Japanese tonkotsu.

>kotsu – 骨, bone, same character is gol in Korean, gu in Mandarin.
>KATSU – カツ, English “cut” from “cutlet”. I capitalized it since it’s a new foreign word, sort of like karaOKE からオケ, “empty orchestra” or orchestra with no lyrics.
>gyu – 牛, cow/ox (original Japanese: ushi) and there IS such a thing as “gyukotsu” ramen. Same character is u or oo in Korean, niu in Mandarin.
>cho – bird, chicken (鳥/鶏) (original Japanese: tori). Same character is jo in Korean, niao in Mandarin.
>gara – がら, an original Japanese word meaning leftovers or skeletal remains, so torigara soup　would be poultry bone-based or chicken bone-based.
