Barely 48 hours after US President Donald Trump left Japan, a helicopter has crashed, leaving at least four people dead.

The private helicopter crashed in a mountainous area and went ablaze on a bridge in the small village of Ueno, a good distance away from the capital Tokyo.

"Four people on board the AS332-L Super Puma helicopter were found dead," a transport ministry official told AFP on Wednesday.

Trump first landed in Japan on Monday on a five-country tour of Asia, where he discussed business and security with president Shinzo Abe.

Trump left Japan for South Korea on Tuesday and has arrived in China on Wednesday. He will also visit Vietnam and the Philippines.

Though the helicopter crash has no link to Trump’s visit, we can't help but note the timing?
