The original song of this song is Chen Ming, which belongs to a lively and affectionate pop song. In the interpretation of saxophone, we usually pay attention to the accurate transmission of melody and the profound expression of emotion, rather than adding additional language elements.
So unless there is a particularly creative version, it is generally impossible to add a Japanese dialogue unrelated to the original song at the beginning. Individual performers or arrangers may add unique elements to music works, such as short sentences in different languages, to increase the diversity or expressiveness of the works. This situation is rare, but it does exist.
If this saxophone version is based on the version of "Hao's Bulk Japanese Songs" discussed online, there may be special treatment, because the original content does involve the cover of bulk Japanese songs.
