Japan Carrier Co., Ltd. said Mineo Maruyama will become representative director and president on April 1, 2026. On the same date, Toru Kubo will step down as representative director and president and assume the role of chairman. The company is the Japanese unit of Carrier Global Corporation.
Maruyama joined Toshiba Corporation in 1995 and worked in sales and business planning in the social infrastructure and consumer electronics businesses. He later held overseas assignments in Asia centered on Singapore, as well as in Russia and the United States, and was involved in the management of global operations.
After joining Toshiba Carrier Corporation in 2018, Maruyama held senior roles in the overseas business strategy function and also served as president of the company’s local subsidiary in China. After returning to Japan Carrier, he led the transformation and growth of the domestic business, became vice president in July 2025, and promoted the transformation and growth of the field service business. In January 2026, he took charge of overseeing the air-conditioning business division, sales division, overseas business division, and data center business promotion division.
Kubo became president of Toshiba Carrier in 2018, when the company was the predecessor of Japan Carrier. Since August 2022, he has served as president of Carrier’s Japanese unit and, according to the company, led major internal transformation. As chairman, he will work on maintaining and enhancing the corporate brand and strengthening relationships with the air-conditioning industry, broader industry groups, and key customers.
Commenting on his appointment, Maruyama said: “What we value most is to stand from the perspective of everyone involved in air conditioning. The voices of not only customers who use our products, but also those who work with technology every day in design, installation, and maintenance, are our starting point and the source of our growth.” He added that Japan Carrier will provide products and services that balance environmental performance and economic efficiency in the Japanese market.
