Dates and cost of studying at the International Study Institute
Did you know that Japanese language schools in Japan have 4 key start dates per year?
The start date you choose not only defines when you start your studies, but also the maximum duration of your visa. For example, if you start in April, you can opt for a full 2-year program, which is the maximum duration allowed. On the other hand, if you choose July, October or January, the visa time will be adjusted to the duration of the course you select, which can range from 1 year and 3 months to 1 year and 9 months.

July (1 year and 9 months): An option that covers all course content with added flexibility.
October (1 year and 6 months): Perfect for those who want an intensive program that accelerates their learning.
January (1 year and 3 months): A shorter duration but equally focused on achieving results.
