13th generation Oiemoto, died 72 in 1964 (?).
He eliminated a lot of temae in a great streamlining effort:
- Usucha Chawan Kazari
- Natsume Kazari
- Irekodate Koicha
- Nagashidate Koicha
He also made changes to the Okuden:
- Changed the Katakuchi mizutsugi from mage-mono to yaki-mono.
And the Juuden:
- Moved the chashaku from right to left in Gyo no Shin iirc?
