Weather could play havoc with Ireland's Rugby World Cup hopes.
A typhoon-watch warning has been issued for their final pool game against Samoa in Fukuoka on Saturday night.
Typhoon Hagibis is developing off the south coast of Japan, and could bring heavy rain and high winds this weekend.

If the match is called off, the two sides would share the points, taking Ireland's quarter-final ambitions out of their hands.
Should Scotland beat Russia with a bonus point and follow that with victory over Japan, the Irish would miss the playoffs and a potential final-eight showdown with the All Blacks.
World Rugby is monitoring the situation with local authorities and haven't ruled out shifting the match to another location.
Ireland defence coach Andy Farrell said World Rugby was as "keen as we are to get this game played", the BBC reports.
"The weather forecast changes all the time anyway, so we won't probably know until 48 hours out from the game," Farrell said.
"The boys haven't even spoken about it - we just go from day to day, get on with our preparations."
