Ban Dainagon Ekotoba

Ban Dainagon Ekotoba (伴大納言絵詞) is a late 12th century emakimono (handscroll painting) depicting the events of the Ōtemmon Conspiracy, an event of Japan's early Heian period. The painting, attributed to Tokiwa Mitsunaga of the Tosa school, is over 20m long and about 31.5cm tall.

The full-color painting depicts the events of March 866, in which Ban Dainagon, also known as Tomo no Yoshio, set fire to the Ōtemmon gate of Kyoto. He then blamed one of his political rivals, Minister of the left Minamoto no Makoto for the fire. However, the true culprit was soon discovered, and Tomo no Yoshio was banished to Izu province.

Stylistically, the scroll is interesting because it is done using a combination of the otoko-e and tsukuri-e styles. Calligraphic lines are used to define figures, which characterizes the otoko-e style used in the shigisan-engi scroll. However, thick coats of bright colors are used in some scenes, typical of the tsukuri-e style used in the Genji Monogatari Emaki.
