Learning to Love, Loving to Learn

Strengthening our Seisen bond, Spreading Seisen spirit

Seisen Former Students' Association was established in August 2010 to unite all former students of Seisen. Our key mission is to establish a global community of Seisen former students and provide a network for everyone to connect with each other, remain connected to Seisen, and keep updated on the school's current news and events. Our association is 5,000 former students strong. Ninety-five percent of our former students live outside Japan. We work together from across the globe to strengthen our Seisen bond, spread Seisen spirit, and make our association as great as it can be.

THE OFFICERS OF THE SEISEN FORMER STUDENTS' ASSOCIATION:

  • President Mary Chu (‘81)
  • Vice President Nozomi Shinoda ('76)
  • Secretary Marie Gaardahl ('10)
  • Treasurer Kazue Yoshimura ('80)

Seisen on Social Media

    We would like thank the Seisen Former Students for their ongoing support and understanding of our community effort to safeguard students during the regular school day by checking in at the Main Office, following our visitor etiquette, and proudly wearing their Former Student visitor tag.

    Visiting Seisen

    We love having former students come to visit but would ask as a courtesy that if possible you let us know a few days in advance through info@seisen.com so as we can arrange a tour for you. We love hearing the memories evoked as you take the tour and your impressions of any changes or improvements to the campus since your time as a student. Ms Rogers is always happy to chat and answer any questions you may have about the school, former students, and former teachers.

    If you are a more recent former student (from 2014 on) who may still have family, former teachers, and friends at Seisen we welcome you to drop by but to still follow the requested procedures and sign in at the Main Office to receive your Former Students badge.

    Former students and colleagues are always welcome to attend games and concerts.

    Welcome “Home”!
