What if the gya, gyo, gyu as in gyudon became pronounced as J which causes the merger of /gj/ and zj and kya, kyo, kyu as in Kyoko became pronounced as Ch merging /kj/ with /tj/ how would this affect the orthography of Japanese.
I read some dialects have words that shifted from /gj/ and /kj/ to /zj/ and /tj/
I am planning to use a Japanese AH conlang with these changes for example Gyoza is pronounced as Joza in my conlang.
