Winger Natasja Behan feels that Ireland needs to improve on the result despite the convincing result last Saturday
"We’re excited to hit the ground running and get a win under our belts.
“But we had a few errors in the first Test so we need to put in the hard work to fix them and put in another good shift this week.”
The Ireland squad arrived in Tokyo ahead of Saturday's second Test on Monday. Nicole Cronin will not be available for selection this week through injury, while Vicky Irwin has been called up and has joined the group in Japan.
