Three of Britain's Olympic mixed relay champions will compete in Japan: Alex Yee, who finished third in last year's WTC Series, 2020 winner Georgia Taylor-Brown and 2019 runner-up Jessica Learmonth.
Their gold medal-winning team-mate Jonny Brownlee, the 2012 world champion, will focus on the Leeds round on 11-12 June as he builds towards the Commonwealth Games in Birmingham later this year.
Elsewhere, Norway's Kristian Blummenfelt and Bermuda's Flora Duffy will be aiming to defend their world titles.
