Katsuhito Tokuhisa missing fights

[Mastrangelos]

I found YT channel with fights of this guy that are not mentioned on boxrec.
This one I believe is Katsuhito Tokuhisa - Sumiyoshi Nohira. There is a date on this fight also, but I don't know if it's reliable for you.

Also, here is footage of his fight against Juan Manuel Chavez:

At the beginning you can hear announcer reading judges name, if you have someone from JApan here, he should be able to catch those names(I have problem with that). Also, at the end you can see video creator writing the scorecards, but I don't know if it's reliable for you.
I don't know if you'll find a way to confirm it and find date and venue, but I thought I will post.
