Iwao Ōtani

Iwao Ōtani (Japanese: 大谷 巌, Hepburn: Ōtani Iwao, born 1919) is a Japanese recording engineer who has worked with influential film directors Akira Kurosawa and Kenji Mizoguchi.
Ōtani worked on Kurosawa's 1950 film Rashomon in Kyoto. Due to setbacks and some lost audio, the crew took the urgent step of bringing actor Toshiro Mifune back to the studio after filming to record another line, which Ōtani added to the film along with the music, using a different microphone.
He won the Mainichi Film Award for Best Sound Recording for the 1953 film Ugetsu. In 2000, he worked on the sound for Kon Ichikawa's film Dora-heita.
