Prime Minister Chris Luxon aims to spend the next few days in Japan, boosting international business opportunities. 

Japan is the world's fourth largest economy, and New Zealand's fourth largest export destination.

Otago University international relations professor Robert Patman says Japan is potentially a very important economic partner for us.

"We are seeing steadily improving trade with them as part of our arrangement - but obviously, we'd like to give it a boost. I think it's a really smart move on the part of the Government."
