Ben Johnston (Papamoa), who has just been called up to the team, also has Sanyo Cup experience under his belt, having represented New Zealand at the 2015 event.
The team also includes some newcomers to the high-performance programme - Claudia Kelly (East End), Samalulu Clifton (Mairangi Bay) and Atakura Julian (Lyall Bay), who is also a new addition to the team.
Coach Danny Morrison said he and team manager Steve Vaughan could not be happier to have Jess lead this year's team.
"Jess stood out as someone who has really taken control of her own destiny in the sport and is very driven to make the step up to the next level of international competition.
"Being her third trip to Japan, and having completely dominated the Ironwoman in the 2016 event, the selectors and management team are very confident that she can provide some real value to the team on and off the beach. She has a great surf head on her shoulders and has shown a level of maturity that will help her make the most of this role."
Jessica said she was honoured to be selected as captain and to have the opportunity to lead and race with a talented bunch of athletes on an international stage.
As she had raced twice before in Japan, she was looking forward to sharing her knowledge about racing conditions and the culture with her teammates.
"That will be awesome to share with the newbies. Last year the racing was tough and it was awesome to see the Japanese really putting their foot in the door."
The two days of racing will include events such as surf race, board race, oceanman/woman, beach flags, beach Sprint, board rescue, tube rescue, oceanwoman relay and beach relay.
New Zealand will join teams from Australia, United States, Great Britain, Netherlands, South Africa, Hong Kong and Japan.
