Summary
Iwai Beach in Minamiboso, Chiba hosts the finale fireworks of the Iwai BEACH Fes. on August 5. About 1,200 shells, centered on star mines, rise over the evening sea from a launch point a mere 140 meters from the viewing area — close enough to feel the thump with the sound of the waves. The beach program starts at 16:00 with a row of food trucks, and JR Iwai Station is a 10-minute walk; the free lot is limited, so public transport is worth considering.
Overview
The gentle shore of Iwai starts its day in the glow of the setting sun, with beach events and food trucks from 16:00. The finale belongs to the sky: roughly 1,200 shells, mostly star mines, launch close to shore so that the sound arrives as a physical wave over the water. Viewing is free, and the front of the beach fills earliest — arrive 30–45 minutes ahead if you want the immersive close-range stretch. The free parking is limited in number, so the 10-minute walk from JR Iwai Station or an early arrival by car are the sensible plans.
