Yuya Ogawa
Co-founder and CTO of Diamond Hands. He's the tech guy for Diamond Hands and is responsible for developing of Diamond Wallet etc. He's kind of low-profile but he's built a lot of interesting Lightning products in the past.
Kishin Kato
The up-and-coming Bitcoin and Lightning developer from Japan. He's getting more active outside Japan recently and I'd expect he'll make name for himself in the future.
He also did a great job moderating and speaking on multiple sessions at Bitcoin Tokyo.
Teruko Neriki
She works for Fulgur Japan and she's also a co-organizer of Bitcoin Tokyo 2024. She's also known as the Japanese translator of Bitcoin Standard and other Bitcoin related books.
Joe MIyamoto
A solid Bitcoin developer and also a funny guy from Japan. He now works for a local exchange but seems to be suffering from working on non-Bitcoin related stuff. Somebody save him!
