Found this interview with Dad from 2011.  He was only 88 at the time.  There is both text and a nice video. I enjoyed spending those two hours with him telling stories from his past.  Reminded me how much he had seen and done, and overcome.

Yutaka Kobayashi served on the board of directors of the Nisei Student Relocation Commemorative Fund scholarship fund from 1992 to 2021, and as president from 1998 to 2002. We are so lucky and grateful to have benefited from his wisdom, generosity, commitment, and “big picture” optimism for the Fund and its future. He is greatly missed. – NSRCF Board of Directors (www.nsrcfund.org)

We were sorry to hear of the passing of Uncle Yutaka. Our deepest condolences. He will be greatly missed.

Dan and Amanda Kobayashi.
