A Fijian rugby player with a Japanese professional team has died after being taken to hospital with symptoms consistent with severe heatstroke, his club Kyushu KV said on Saturday.

The 26-year-old Saimoni Vunilagi was hospitalized in Fukuoka after a team practice on Monday and died on Friday morning. Temperatures in Fukuoka reached 35°C (95°F) on Monday.

Vunilagi, a back-row forward standing 196cm (6ft5in) and weighing 117kg (258lb), attended university in Japan and began his professional career in 2023.

The club stated: "The players, staff, and all team associates are devastated by this sudden news. Although Saimoni had only recently joined Kyushu KV, his generous spirit and powerful style of play had raised high hopes for his contributions in the upcoming season. We humbly pray for the repose of his soul and extend our heartfelt condolences to his bereaved family."

Japan sweltered through its hottest summer on record last year, and parts of the country have hit 40°C (104°F) in recent weeks. Nearly 18,600 people were hospitalized for heatstroke between July 20 and 26, with 45 pronounced dead on arrival, according to the fire and disaster management agency.

Japan experiences about 1,300 heat-related deaths annually and aims to halve that number by 2030. Three lions at a Tokyo zoo died from suspected heatstroke, and others are under treatment.

Scientists say human-induced climate change is increasing the frequency and intensity of extreme heat events in Japan and elsewhere. The country's highest recorded temperature of 41.8°C (107°F) was registered on August 5, 2025, in Isesaki.

Authorities have adjusted the timing of several cultural and sporting events in recent years because of the heat, including the World Cosplay Summit in Nagoya, which held its final summer edition last weekend.
