A newlywed Japanese man suddenly collapsed and died in Singapore on Wednesday, the last day of his honeymoon, officials said Friday.

Hiroyuki Oyama, 34, died around 10:30 p.m. after collapsing in the departure hall at Changi airport.

Singapore's Straits Times reported Friday that Oyama had complained of chest pains.

Oyama and his 31-year-old wife were about to return to Japan after holidaying in Indonesia and Singapore.
