Background

He joined Denso in April 1981, became a Managing Officer in June 2008 and a Senior Managing Officer in June 2014, and President in June 2015. He is a career employee with repeated overseas postings. Among major shareholders for the fiscal year ended March 2015, Toyota Motor held 22.31%, Toyota Industries 7.85% and Towa Real Estate 3.77%, with the Toyota group occupying the top spots.

Education: Kyoto University, Faculty of Engineering (1981)

Selection

In June 2015 he succeeded Nobuaki Kato as President. In the fiscal year ended March 2015, the year before, consolidated revenue was ¥4,308.7 billion and operating income ¥331.4 billion, down from ¥377.7 billion in FY ended March 2014. The Ministry of Economy, Trade and Industry and others estimated that about 11,000 of the roughly 30,000 parts in a car would become unnecessary with the shift to EVs, and the stock market was marking down parts makers with a high dependence on internal combustion engines. The appointment appears to have entrusted him with reshaping the company toward electrification.

Initiatives

In October 2017 he set the Denso Group 2030 Long-term Policy and the 2025 Long-term Vision, targeting revenue of ¥7 trillion and an operating margin of 10% in fiscal 2025 across four fields: electrification, advanced safety/automated driving, connectivity and non-automotive. In November that year Denso raised its stake in Fujitsu Ten from 10% to 51%. In April 2020 it launched MIRISE Technologies, an automotive semiconductor company owned 51% by Denso and 49% by Toyota. Following the large-scale fuel pump recall of March 2020, the provision for product warranties reached ¥254.3 billion at the end of March 2020.
