Australian captain Michael Hooper will play overseas for the first six months of 2021 and miss most of the Super Rugby season.
The Wallabies and Waratahs flanker is expected play in Japan next year. Rugby Australia (RA) said he will return to Australia in time for their 2021 Test calendar.
A set number of current players will be granted six-month releases from their contracts after the Rugby Union Players Association and RA signed an interim pay deal in April due to the financial impact of the COVID-19 pandemic.
"This is a great opportunity for me to learn in a new rugby environment and develop a different perspective on the game," Hooper, who has been capped 99 times by Australia, said in a statement.
"I'm really excited in the direction of Rugby in Australia both at a Super Rugby level and at the Wallabies too under Dave (Rennie)."
RA interim chief executive Rob Clarke said the governing body was "incredibly supportive" of Hooper's move.
"It's a prudent decision, especially for someone who has been a devoted servant to the domestic game here in Australia for over 10 years now," said Clarke.
"While he will head overseas for the first six months of next year, Michael has made it abundantly clear how committed he is to Australian Rugby until at least the Rugby World Cup in 2023."
