Manchester City winger Ryotaro Meshino is impressing on-loan at Hearts.
Jambos boss Craig Levein says Meshino has been influential in the dressing room despite the many learning curves he is undertaking.
“He isn't fluent in English but he is taking lessons three times a week and that has improved," Levein told The Scotsman.
“The boys are teaching him a few words in the dressing room that maybe they shouldn't be teaching him but he is a bubbly wee character. I think that will help him.
“This is a fair change in culture, it's a fair distance away from his home, it's a different language.
"Most foreign players who come to the UK, particularly from Japan, are very unlikely to be speaking fluent English. He's got that to contend with, plus the football and the weather. He has been more to forefront in the dressing room that I would have thought."
