Rotorua welcomed its sister city and its new mayor, Yasuhiro Ngano, with a pohiri at the Government Gardens.
Councillor and cultural ambassador Trevor Maxwell said the two cities had a strong and beautiful relationship.
"We are really lucky," Mr Maxwell said.
Beppu in Japan and Rotorua have been sister cities since 1987, when the Rotorua mayor at the time, John Keaney, established the relationship.
Since then it has been strengthened by a former mayor, Grahame Hall and over the past two years by the incumbent Steve Chadwick.
