Matsushita, 43, was killed at Ballacrye in the north of the island on Monday, with the race session immediately red-flagged as a result of the incident.
He is the 21st rider to die at the Isle of Man TT since 2000.
The experienced rider, from Saitama in Japan, had only entered the race with Tyco Suzuki hours earlier - joining Lincolnshire's Guy Martin and Australian BSB star Josh Brookes.
On his entry being announced, Matsushita had revealed that 76-year-old former Suzuki rider Mitsuo Ito - the only Japanese rider to ever win a TT - would be helping him prepare for the physical and mental challenge.
He also spoke about how much it meant to him to compete on the Isle of Man.
The ACU wishes to pass on their deepest sympathy to Yoshinari's family and friends.

"As a member of this great team for the TT, I draw the full power to be able to use their experience to fight this monster course at best," Matsushita had told the official Isle of Man TT website.
"For several years, I have wanted to fulfil my ambition to race in the Supersport 600 class."
Matsushita first competed at the TT Races in 2009, finishing fifth in the 2011 TT Zero for electric bikes, as well as racing in the superbike and superstock classes.
Gary Thompson, Clerk of Course at the Ile of Man TT, said: "Yoshi was a really popular competitor who had a large number of friends in the TT Races paddock.
"He was a genuine and friendly character who always had time for everyone. He will be sorely missed."
An investigation into the circumstances of the crash is underway.
