I got a “日本語上手” for the first time

Hi this is my first time in japan and while exploring Tokyo national museum i got to talk with an old man explaining japan history and he told me 日本語上手 after i spoke Japanese it although im still N4 but I managed to get a good conversation , in general I didn’t know that i really can speak Japanese better than i thought in my head so to anyone there learning Japanese you probably better than you think
