Wow brother... We have received many videos and information that mention Japanese students interpreting emblematic themes and not only that, but traditional music, just as we do it or maybe better. You have interpreted the gaita zuliana, the calipso guayanés, the joropo llanero (that we share with Colombia) and I don't know which other one.... But you have.
In my city, I understand that Japanese engineers were involved in the construction of one or more dams and the installation of several iron ore processing plants.
Hence their interest in learning Venezuelan music in those 70's-80's and maybe more of the last century and taking it with them to your land at the end of the contracts.
Pleased to greet you once again
