Does anyone know what happened to Isoda Electric?

Hello, around 2016 I received some samples and custom build cables from Isoda Electric in Japan to be used for resale and for our speaker prototype.
After awhile i lost contact with Mr. Yukido Isoda..........I have tried to look him up but he seems vanished. Do anyone know what happened, is the company gone? sold? taken over by the family and ended up with same destiny like Graaf (Italian OTL tube amp manufacturer)
Curious coz I like to buy a batch of cables.
Best
Mike
