Experience transformation through carefully curated programming

Participants arrive in Toyama and prepare for IAC27. Students joining the homestay program meet their host families and begin their two-night homestay experience.
The evening is intentionally relaxed, allowing students to share dinner, conversation, and everyday family life with their hosts.

A Welcome Reception / International Exchange Program is also being considered in collaboration with relevant partners.

The second competition day brings IAC27 to its official conclusion with final competition sessions, awards, and the closing program.
Homestay participants leave their host families in the morning, and participants requiring accommodation transition to their hotels following the event.

Participants and families may extend their IAC27 experience with an optional full-day Tateyama tour.
Discover Toyama’s spectacular mountain landscape through scenic transportation, nature, walking, and time together with other IAC27 families.
Stay with a local family in Toyama and experience everyday life in Japan beyond the competition. Share meals, connect across cultures, and create friendships that go far beyond the classroom.
