McClutchie left this week to prepare for the January to May Top League comp and will return to the Bay for the Maddison Trophy rounds in club rugby and the Magpies 2020 campaign.
"The opportunity provides Lincoln with an ideal chance to continue developing and working on his rugby while the chance to experience another culture and lifestyle will enable him to return to our environment a vastly improved and more mature player. Training and playing alongside a player like Marty Banks can only be of benefit to Lincoln and in turn the Magpies when he returns,'' Hawke's Bay Rugby Union CEO Jay Campbell said.
Docomo is located in Osaka, a city of just over 2.5 million people, and a city known for its love of rugby.
"Hawke's Bay club rugby has benefited from having a number of promising players from Docomo playing in our premier club competition over the past few years and it's exciting that Lincoln becomes the first Magpie to head in the other direction which can only be of benefit to him as I know how much he wants to prove himself and secure a Super Rugby gig."
McClutchie is expected to be Banks' deputy but given the limited number of foreign players on the Red Hurricanes roster he should receive plenty of game time.
Hawke's Bay has another link to the club with former Magpies front rower Greg Fleming the Docomo forwards coach.
"Having Flem around will be great for Lincoln as he will help him settle in and he can keep a watchful eye on him as he transitions into life in Japan. Lincoln is such a resourceful and hardworking young kid and I'm positive this experience will be the making of him," Campbell added.
"A large part of our role is to promote as many of our players to Super Rugby. In this instance, with Lincoln, it's a promotion to a great opportunity where he can train as a professional for six months and work fulltime on his rugby in Japan. I'm really happy for Lincoln and I look forward to his return and seeing the growth in him both as a player and also a more confident young man," Magpies head coach Mark Ozich said.
McClutchie will be one of two current Magpies playing in the 2020 Top League. Lock Tom Parsons will turn out for the Toshiba Brave Lupus who are coached by former Crusaders mentor and All Blacks captain Todd Blackadder.
The pair are expected to provide major boosts to their respective clubs, Tamatea and Central, when they return to the Bay in May.
