The Sapporo Lilac Festival began in 1959 at the urging of cultural figures who proposed “holding cultured events in the season when lilacs bloom,” and it heralds the arrival of early summer in Sapporo. Centered in Odori Park, where about 400 lilac trees blossom, the festival features a variety of programs such as the Lilac Music Festival, a wine garden, and a stamp rally. The Kawashimo venue, where more than 200 varieties are in full bloom, is also included, and the festival will be held in May 2026.
