- The Kyuden Voltex club said Vunilagi collapsed after a training session, displayed symptoms consistent with severe heatstroke on Monday, August 3, was taken to a medical facility and died on Friday, August 7.
- The team described players and staff as devastated, offered condolences to his family and asked for privacy while supplying no further medical or investigatory details.
- Reports said temperatures in Fukuoka reached about 35°C (95°F) on the day he fell ill, a factor the club cited when describing his symptoms.
- Vunilagi had joined Kyuden Voltex in July after playing for Tokyo Sungoliath and studying in Japan, and teammates and the wider rugby community marked his death with gestures including a minute’s silence before the Japan v Australia Test.
- No independent medical ruling or detailed timeline of treatment has been published, and the case could prompt closer scrutiny of heat protocols for clubs preparing for the season.
