refused to take any royalties from the games at all, proudly boasting that "not a single yen has gone in my pocket."
The series' DS royalties alone are over 2.4 billion yen -- about 22 million dollars USD -- half of which Kawashima is entitled to (the other half going to Tohoku University, his employer). Rather than taking the money, Kawashima is content to support his family of four with his own wages, which are around $100,000 USD.
A self-declared workaholic, Dr. Kawashima has dedicated his life to his research into the aging of human brain, which was the genesis of the Brain Training games. We're happy you like your job so much, but don't you think your wife and four sons could benefit from a bit of that brain money?
