Sponsorship of the 'YONEX LADIES GOLF TOURNAMENT 2026'

Thermos K.K. (Headquarters: Minato-ku, Tokyo; President: Yuji Kataoka), a global leader in vacuum-insulated products proposing comfortable and eco-friendly lifestyles, will sponsor the 'YONEX LADIES GOLF TOURNAMENT 2026,' a professional women's golf tournament held over three days from June 5 (Fri) to June 7 (Sun), 2026, at the Yonex Country Club (Nagaoka City, Niigata Prefecture). Following last year's event, the company will present 'Vacuum Insulated Sports Bottles (FJU-751/1001)' to participating players and caddies, and hold a raffle for spectators. Participants can enter the raffle using the number on their ticket stub, with 100 winners each day (300 in total) receiving a 'Vacuum Insulated Mobile Mug (JNL-S500).'

Purpose of Sponsorship Thermos sponsors the tournament to promote the information that hydrating with beverages between 5°C and 15°C is effective during sports activities. The goal is to encourage players, caddies, and spectators to maintain proper hydration during the hot summer months. By promoting the use of personal bottles that keep drinks at this optimal temperature, Thermos aims to spread awareness of heatstroke prevention.

(*Note: The 'Thermos 5-15°C PROJECT' is an initiative based on experiments proving that 5-15°C is the optimal temperature range for hydration in high-temperature environments.)

Sponsorship Details 1. Donation of 'Vacuum Insulated Sports Bottles' to players and caddies. 2. Raffle for spectators to win one of 300 'Vacuum Insulated Mobile Mugs.'
