They'll attend Moruya High School, live with host families and teach the school's Japanese students a thing or two about their homeland.

The school's Japanese teacher, Matt Cusack, said the seven and their teacher arrived last Sunday and would stay for three weeks.

30 students from Japan travelled to Australia via the LABO organisation, and Moruya took the highest number of students each trip, Mr Cusack said.

"They will be helping Moruya High School students practiase their language skills and teach them Japanese craft and culture," he said.

They would also teach a few Japanese cooking and origami classes.

"They're loving it. A lot want to come out with this organisation and only 30 make it," he said.

The girls won the school over early when they sang "Waltzing Matilda" at a school assembly.

Mr Cusack said the assembly had joined in with clapping by the second verse and was singing along by the chorus.

He said the girls' English was a bit stilted, but he said they'd improve by the end of their time in Moruya.

Exchange student Haruka Sadamasu had been thrilled with Australia so far.

"Moruya is a good place, and has a good teacher," Ms Sadamasu said.

"Yesterday, in morning, I see kangaroo in front of my house. I think it was a great experience. There is no kangaroos in Japan."

Ms Sadamasu was surprised Canberra was the nation's capital when Sydney was so much bigger.
