He has signed on to a team in the highest tier of Japanese football, where he will play until October.
The youngster, who is now 20, has been at the club since he was 16 years of age.
This will be his first spell away from the Molineux team, having played for their under-18s and under-21s.
Pathways manager Steve Davis said: We were looking for a loan for Justin, maybe in the summer rather than now, but the opportunity came along.
Osaka made contact and we followed it up. They were after a center back because they'd had an injury to one of their key players at the back and with Justin's link with Indonesia in that Asia market, we felt it would be a good one for him.
It's a different market for him to be in, different sort of league. The style of football in the J1 League is very strong and it will be a really good challenge for him. We just felt that for his footballing development, that would be a great step and a good challenge.
He's been doing really well in the under-21s and has had a good season. He just needed more of a challenge and the J-League will give him that step up he needs now moving forward."
