"I've lined up a number of business meetings in Beppu and Tokyo with people involved in these sectors and I have site inspections arranged for some of Beppu's spa and hot springs developments.
"I'm also going to be looking at some examples of geothermal power generation for tourism facilities and 'jigoku mushi' - cooking using geothermal-generated steam.
"Our council wants to see the unique natural geothermal attributes of our own at Kuirau Park substantially developed in the future so the park can become a focal point of Rotorua's geothermal experience.
"At present, Kuirau Park is not realising its potential. It's under-developed, under-utilised and falls short as a quality international visitor attraction, so this is a chance to look at ideas for transforming Kuirau Park into something special," Mrs Chadwick said.
Beppu became a sister city of Rotorua in 1987. There have been numerous visits to Rotorua by groups and individuals from Beppu.
The council's sister-city agreements provide for official visits every three years.
Mrs Chadwick will be accompanied by her husband John, councillor and cultural ambassador Trevor Maxwell and Rotorua-based Japanese business woman Yumiko Kawano-McGovern as interpreter.
The delegation leaves tonight and returns next Monday.
