Collin said later the same day he went to play a round of golf with Wilson.
The pair played several holes when the defendant advised he "needed to do something'', picked up a golf club and walked away.
"Fearing something was wrong, the victim followed him.''
Wilson tried to stop Yoshimine and calm him down, however, he started running towards his place of employment, went to the rear of a business portacom and struck a closed glass sliding door with the club.
He was taken to the ground by the victim and eventually calmed down.
"However, without warning, he approached the victim and struck him once with a closed fist to the left side of his face.
"He was restrained by staff and customers holding him on the ground as he yelled and lashed out.''
Lawyer Joseph Mooney said Yoshimine put the incident down to "work-related stress''.
"He is very eager to return to Japan and go to a hot spring for a few days and de-stress, so to speak.''
On both charges he was convicted and his sentence deferred for six months
