There are different Japanese courses in Hong Kong. According to students' age, Japanese language schools and centres provide courses for children, parent-child combinations, and for adults. As for students who aim at the JLPT exam, they can take N1-N5 courses or other intensive courses. There are also private tuition courses (including native Japanese living in Hong Kong), training students' conversational skills. Some teachers are willing to teach you one-on-one at your place.
