Yasuo Masumoto, chairman and president of Kubota Corp has died while staying in a Tokyo hotel. He was 67.

The executive failed to leave his room after breakfast and was found collapsed in the bathroom after the company raised concerns, a spokeswoman for the Osaka-based manufacturer said by telephone today, declining to be named in line with policy. The cause of death hasn’t been determined, she said.

Vice President Masatoshi Kimata takes over as acting president, the spokeswoman said. Kyodo News reported the death earlier.

Masumoto joined Kubota in April 1971 and rose to the rank of president in 2009, adding the position of chairman two years later, according to data compiled by Bloomberg. He held stock in the company worth about $893,401, the data show.

He oversaw Kubota’s purchase of Norway’s Kverneland ASA, which was completed in May 2012. The Japanese industrial machinery maker also bought Shin Fujikasui Engineering Co. the same year.
