Nurturing our Passions

We offer a wide range of student activities across physical, creative, intellectual, and service-oriented pursuits. Students learn best when engaged with their passions; our activities nurture students' dreams for life-long learning, personal growth and fun.

Our elementary school activities (ESA) program includes a range of sporting, games, music, art, dance and recreational activities for students in kindergarten - Grade 5, supervised by school staff, parents and visiting instructors or leaders. Students are given a wide variety of opportunities to develop their skills and extend their experiences, and we encourage all students and teachers to participate. Parents are likewise able to become involved in the program as they are often invited to help out as chaperones for the various activities.

Elementary activities vary from year to year depending on teachers’ interests. Choices continue to change and evolve, and updated information is listed in the elementary activities catalog posted before the start of each season.


The ESA program runs over three sessions, on Mondays, Wednesdays, Thursdays and Fridays, beginning in September, January, and March. Activities start at 3:15 pm and finish at 4:00 pm, unless otherwise notified.

Prior to each session, we post a catalog of the activities available for that session and a link to online activity signup via the parent portal. We make every effort to place children in at least one of the activities they request, but families should be aware that activities are not necessarily offered on a first come, first served basis. Rather, we take into consideration a variety of factors (e.g., activity size, age and gender balance, etc.) in selecting the activity groups. The great majority of our activities are supervised by YIS staff and do not involve any extra fees. There are a few activities offered by outside providers (such as aikido and individual music instruction), which involve a separate activity fee.


Once enrolled in an activity, students are expected to attend all sessions unless they are absent from school. On occasions where it is unavoidable for students to miss a session or withdraw from an activity, parents should notify the activity supervisor. Students are expected to leave the school premises as soon as their activity has concluded. Parents collecting children should do so promptly from the playground.


Activities may be canceled in the event of inclement weather or other circumstances, such as illness of the activity supervisor. Whenever possible, we will try to provide advance notice of cancellation via email and parents are also advised to check the school website.



We offer an abundant variety of clubs and activities for middle and high school students, ranging from sports to music and drama, service, student government and much more. Offerings may be found in our Secondary Activities Catalog.


Most clubs and activities take place after school (usually 4:00 – 6:00 pm but occasionally up to 7:00 pm) but some meet before school (8:00 – 9:00 am) or during lunchtime. Some activities, for example many of the sports games/tournaments, also take place on the weekends. Students sign up online via the student portal during the designated period in early September.

Some secondary activities run for all three seasons, while most are held for one or two sessions. The great majority of our activities are supervised by YIS staff and do not involve any extra fees. In the case of some high school activities with matches or tournaments outside the Yokohama/Tokyo area, students are responsible for covering travel fees.






It is important that students carefully select activity schedules in light of overall time commitments, including study needs, commuting times, etc. We encourage a healthy balance among academics, sports, fine arts and service programs. While we believe that an active and involved student is a healthy student, we also believe that it is important for students and their families to make informed decisions about the level of that involvement. Too little involvement can mean that a student is not taking advantage of his or her school years, while too much involvement can impact on academic success.

If students are to opt for, and be successful in, gaining a place in a team or in a performance, they have a responsibility to commit to the activity. In particular, students studying for DP courses should remember that these academic programs are rigorous and will require time, energy and commitment. Therefore, when selecting activities, students and parents need to discuss and plan time commitments carefully.

Communication with coaches, directors and classroom teachers is important – if students are having difficulties, please make sure they raise these with the relevant people.

We recognize that it is perhaps impossible to fully achieve ‘balance’ to everyone’s satisfaction. Clearly, there are students who can comfortably participate in numerous activities, whereas for some students this may adversely affect their classroom progress. Our policy, therefore, is that students may undertake up to four activities at one time.
