The 24-year old Jubilo Iwata ace is a target for Hoops boss Neil Lennon but will undergo some trial-like training at Lennoxtown for the next week.
Lennon has previously spoken highly of Yamada, telling the Daily Record last month: "He can play left side or off the striker. He looks okay but we'll not have a real idea until we've seen him over here.
"I don't think there would be any money involved - he's a free."
Yamada has been with Jubilo since 2011 and has also represented Japan on two occasions, both which occurred this year.
