Known in Japan under the title Otoko wa Tsurai yo, his Tora-san series features traveling merchant Torajirō, who is always unlucky in love. Since the lead role in every Tora-san movie was played by Kiyoshi Atsumi, his death in 1996 put an end to the series and Yamada moved on to other movies. Although Yamada is known for his long-running series of movies—four films in the A Class to Remember series, 13 in the Free and Easy (Tsuribaka Nisshi) series—none has reached the prolific numbers of the Tora-san series. Over a period of about 25 years, 48 Tora-san films were made, all of them starring Atsumi, and the majority written and directed by Yamada.
