Kihachi Okamoto
In 1981, Japanese director Shohei Imamura produced his film "Eijanaika", which gives a deliberately historically incorrect interpretation of the events but nevertheless catches the unstable and tense atmosphere of the age. Imamura had previously helped write the 1957 Yuzo Kawashima film on the period . This era was also depicted in the 1969 Kihachi Okamoto-directed Toshirō Mifune film . The "ee ja nai ka" activities, hitherto unknown as part of Japanese history during the Bakumatsu, have in recent years been included and alluded to in mainstream historical productions, such as the NHK Taiga dramas "Ryōmaden" and "Yae no Sakura".
