Interviewing Japanese VB devs?

Hi,

So a while back I supported a Kickstarter for a book on Japanese game development (the history and all that) (details here: http://www.kickstarter.com/projects/1748556728/the-untold-history-of-japanese-game-developers)

I backed the project at a high enough level than I can choose some questions to get asked and I thought it would be a great chance to hear some stuff about developing for the VB (back in the day). However, the guy running the project hasn’t been able to contact anyone – that’s why I’m asking here! Who should he try to contact and what should he ask?

thanks!
