The Wicked Reporter (1993)

More than his indie debut Skinless Night, this was the film that launched Mochizuki on his distinctive trajectory through the crime and yakuza genres. Matsuzaki (Eiji Okuda) is a racing tipster for a sports paper, a lowlife who spends half his time drunk, hangs out with yakuza and other riff-raff and complicates his sex life by succumbing to advances from his girlfriend's sister. As played by Okuda, he's also a figure of considerable hangdog charm. Less a plot-based movie than a guide to the several forms of high stakes gambling in Japan, this centres on his attempt to help a friend swindled in a bent mahjong game. Hakuryu appears (memorably) as an inscrutable yakuza in a black leather jacket. The film's success led to two sequels.

Unfortunately the movie The Wicked Reporter is not yet available on HBO Max.
