Studio Aroha has posted a gem of anime history onto YouTube. In 2001 Hidekazu Ohara, an animator who has worked on anime such as classics like Akira and Nausicaä of the Valley of the Wind, as well as commercials such as the Studio 4°C Volvic Water spot, contributed short Keikaku (Lords of the Sword) to the Digital Juice anthology. Then, around 2007, with Katsuhiro Otomo as supervisor, a new Keikaku pilot preview was produced.
From that later, currently unrealized Keikaku (Lords of the Sword) project...
More recently, Ohara did design work for Otomo's Hi-no-youjin segment of the Short Peace anthology. Like Keikaku, it is a period piece, though set in 1657 Edo era rather than the Muromachi period (1337 to 1573).
Hi-no-youjin concerns an Edo era fire fighter brought together with his childhood love during the Great Fire of Meireki, which destroyed more than half of the capital.
