KIST 20th Anniversary

K.20 Celebration

K. International School Tokyo is celebrating the 20th anniversary of its founding, and there is much to celebrate! From its humble beginnings with just one student, KIST has developed into one of the leading international schools in Tokyo with more than 650 students representing 45 different nationalities. Although 2017 is not yet over, it has been a big year for KIST starting in February when the school received full accreditation from the Council of International Schools (CIS), to July with the announcement that its Grade 12 graduating class had achieved an average IB DP score of 38.03 - the highest in the school's history - making KIST the highest ranking school offering the DP in Japan for the third year in a row.

To commemorate our 20th anniversary, we are planning a special celebration! To celebrate our achievements and to thank all those connected to KIST for their support over the last 20 years, we will be holding a special once-only event known as the "K.20 Celebration" at our Kiyosumi-Shirakawa campus. As a result, our school festival, KISTival, which normally takes place at the end of October, will not be held this year in its regular format, though some aspects of K.20 will be similar to the festival.

Details of K.20:

  • Saturday, October 28, 2017 from 11:00 a.m. to 3:00 p.m.
  • Displays depicting the past, present and future of KIST
  • Friendship points for members of each school year (1997 - 2017), including past students and alumni, to gather
  • International food court with sales by professional vendors
  • Stage performances
  • Games and activities
  • Grand raffle with great prizes

To add to the festivities, visitors are encouraged to wear colorful costumes as per the regular KISTival. The bazaar booth will not be held this year, but will return next year for KISTival 2018.

Although K.20 is geared specifically to our school community, members of the general public who wish to come along are welcome to do so; however, entry will be restricted only to those who have purchased entry tickets in advance. Tickets will be available from the school reception counter from October 16 through 26 for 100 yen. Tickets will not be available at the gate on the day of the event. Those without tickets who are not members of our school community will not be able to enter. Members of our current school community (students, parents/guardians, staff) as well as past students and alumni will receive an invitation and complimentary entrance tickets prior to the event.

We look forward to celebrating with you at the K.20 Celebration!
