A seven-person official delegation will travel to Nagaizumi-cho to celebrate the 30th anniversary of a Whanganui sister-city relationship with the Japanese city.
The August visit coincides with Nagaizumi-cho's annual Waku Waku Festival and included an anniversary ceremony and exchange event.
There would also be an opportunity to present information about education opportunities in Whanganui and New Zealand.
It would cost Whanganui District Council up about $15,000 in airfares while Nagaizumi-cho would pay for accommodation, internal travel and food.
The seven making up the official delegation includes mayor Hamish McDouall, council's chief executive Kym Fell, Whanganui & Partners general manager Phillipa Ivory, New Zealand International Pilot Academy chief executive Phillip Bedford, council principal adviser corporate Marianne Cavanagh, councillor Rob Vinsen and former sister cities co-ordinator Malcolm Hunt.
