[Okazaki City] Starting Heatstroke Prevention at Public Baths: 'Heat Acclimatization'

Okazaki Rakunoyu (Okazaki City, Aichi Prefecture), operated by Nakashiro's Raku no Yu Group, is partnering with Otsuka Pharmaceutical to conduct public awareness activities for heatstroke prevention, themed around 'heat acclimatization.'

Starting from May 5, 'Heatstroke Prevention Day,' awareness posters have been displayed at the facility to encourage local residents to take preventative measures. A seminar on heatstroke prevention is also scheduled for Wednesday, May 27, 2026.

With the recent increase in extremely hot days, the risk of heatstroke is considered particularly high before the peak of summer when the body is not yet accustomed to heat. 'Heat acclimatization'—the process of training the body to endure heat and develop a habit of sweating—is gaining attention. Public baths and saunas are noted as accessible ways to sweat naturally in daily life.
