SIJ 2023 will be held in Oita City and Kunitachi City only as a one-day intensive seminar


Thank you for your many inquiries and application requests for Summer in JAPAN.

For 2023, we will not be holding the “7-day English Seminar” and “Sumire Hirotsuru and Friends Concert,” both of which would have been led by Harvard students. We apologize for any inconvenience this may cause.

This summer program started in 2012, the year that Sumire Hirotsuru, co-founder of SIJ, was accepted to Harvard University, and has been a great success with many talented and bright Harvard students joining over the years.

An International exchange between Japan and the U.S.,

a wide variety of classes were held in English for elementary, junior high, and high school students from all over the world.

SIJ was a place for Japanese university students, students from Asia, and top American university students to make friends.

An institution that creates new education

The program continued for more than 10 years as an institution that pioneered a new path for education. We are proud of the achievements of our elementary, junior high, and high school students!

“I love SIJ more than my school!”

“I wish every day was SIJ!”

“I learned not only English, but diversity etiquette!”

“I am better at public speaking!”

It is very rewarding to hear them say with smiles, “I learned not only English but also diversity manners!”

We would like to thank you all for your warm support.

We are taking a break in 2023 because we have decided that the times are moving so fast that our mission of reforming English education and promoting global education alone is not enough to contribute to the development of the talents of the children and university students who will be responsible for the future.

Please wait until we can present our program to you with a new, more impactful mission.

The two-day SIJ seminar in Kunitachi and Oita will be held as usual. The first day will be in July 2023 and the second day in early August.

Thank you for your continued support.

Mari Hirotsuru

Founder, President, Summer inJAPAN
