Mahjong Demon 2: With a White Blade on His Back(1993)

A young professional mahjong player, Sakurai Shoichi (Shimizu Kentaro), who graduated from university, was employed at a real estate company. While on a business trip with the company president (Hamada Akira) to a secluded hot spring town, he learns that an elderly couple who are the president's benefactors are in trouble. The old man was a former gambler who ran the town with honor and compassion, but his business was taken away by an emerging gangster (Hiura Tsutomu). When Sakurai Shoichi finds out that the emerging gangster is making a shady profit from mahjong, he offers to play as a substitute for the player without payment.
