Kenzo Tsujimoto, founder and chairman of game maker Capcom Co., sees similarities in managing the game business and one of his recent interests: wine-making.

The 68 year-old's private business passed a milestone last year as it launched the first vintages from his winery in Napa, Calif., in the fall.

The first shipment — 600 cases — sold out quickly. Buyers included upscale restaurants, including Koju, a Michelin three-star restaurant in Tokyo's Ginza district.
