Murakami City Fireworks Festival in Seiryu Arakawa - Large blooming fireworks reflected on the surface of the clear Arakawa River
The Murakami City fireworks on the clear Arakawa close a two-day programme on 8 August: the eve brings a mikoshi procession and folk-song singing with yukata crowds filling the street before Sakamachi Station, then about 300 shells — memorial bursts and a run of No. 10 shells among them — rise over the riverbed. Free parking holds 700 cars, and bad weather postpones the show to the following days.
A modest, well-loved river-town event of about 2,000 people, where the fireworks are one act in a two-day story rather than the whole story. The water-side setting on the clear Arakawa makes the most of a smaller shell count — reflections do the amplifying. Practicalities are easy: 30 minutes on foot from JR Sakamachi Station, about 10 minutes from Arakawa-Tainai IC, and 700 free parking spaces. The one real variable is weather — rain postpones the launch to the following days, so confirm the day's status with the organisers before travelling.
