20th Anniversary of Municipal Incorporation: Sanmu City Summer Carnival

Summary

Sammu City in Chiba Prefecture marks 20 years since its founding in 2026, and its Summer Carnival — the city's signature summer event — stages a fireworks show on Saturday, July 25. Between 19:50 and 20:00, 1,500–2,000 shells fire from the plaza in front of the observation tower at Hasunuma Seaside Park: a dense ten-minute finale to a day that starts with a lively samba parade. Around 19,000 people attend in a typical year, and free parking for 1,200 cars sits near the park.

Overview

The Sammu City Summer Carnival is the highlight of summer in Sammu, Chiba Prefecture, drawing visitors from inside and outside the prefecture. In 2026 — the 20th anniversary of the city's founding — the carnival's fireworks display doubles as an anniversary event. By day the grounds move to a samba parade; after dark, the fireworks take over at the plaza in front of the observation tower of Hasunuma Seaside Park. The display itself is short and intense: 1,500–2,000 shells fired between 19:50 and 20:00 on Saturday, July 25. Arrive early — a latecomer risks missing nearly all of it. The venue is reached by airport shuttle bus from JR Matsuo Station (about 15 minutes to the Hasunuma-Nakashita stop, then a 15-minute walk), and 1,200 free parking spaces sit near the park. Food stalls are on site, so plan time for dinner before the shells fly.
