Highlights

Koga Fireworks Festival Overview

The Koga Fireworks Festival is one of the largest-class events in the Kanto region, known for its huge “sanshakudama” shells and elaborate starmine displays that deliver both power and production.

The Impact of a Sanshakudama

The 90 cm-diameter sanshakudama blooms into a massive firework spanning several hundred meters, spreading with a thunderous roar from around 600 m altitude—its signature spectacle.

Starmine Highlights

From music-synced fireworks to extra-large starmine sequences and a finale super-wide starmine, the night sky is filled with continuous showpieces.

Typical Schedule

It’s typically held in early August (often the first Saturday). Launch times are usually in the 19:00–20:00 range, so confirm the official announcement each year. The venue is around Koga Golf Links.

Getting There by Train

From Tokyo, take the JR Utsunomiya Line (Shonan-Shinjuku Line) to Koga Station in about 60 minutes, then walk about 20 minutes to the venue.

Potential Viewing Areas

Koga Golf Links (main venue), the levees along the Watarase River (good for wider views), and slightly farther riverbanks (often a reference point for lighter crowds) are commonly mentioned options.

Tips to Avoid Crowds

Arriving early (around 16:00 as a guideline) and adjusting your departure time—leaving a bit earlier or later—can make congestion easier to manage.

Frequently Asked Questions

A. The Koga Fireworks Festival is held on the Watarase River riverbed in Koga City, Ibaraki (Koga City). Reflections on the water are part of the appeal, so framing a slightly wider shot that includes the river surface adds impact.
A. It is typically scheduled for an evening in early August (Koga City). Daytime spot-saving can be harsh in the heat, so arriving in the late afternoon and securing a place near an “exit side” can reduce stress when leaving.
A. The venue is announced as the area around Koga Golf Links (Watarase River riverbed) (Koga City / tourism association). The embankment is dark at night, so a small light can be safer for footing than relying only on a phone light.
A. By train, it’s listed as about a 25-minute walk from JR Utsunomiya Line “Koga Station” West Exit, or about a 20-minute walk from Tobu Nikko Line “Shin-Koga Station” East Exit (Koga City Tourism Association). Stations get crowded after the show, so checking your IC card balance beforehand makes things smoother.
A. Viewing is enjoyed on the riverbed, and some years paid seating is set up (Koga City Tourism Association). Even in free areas, grassy slopes can be slippery, so a leisure sheet with anti-slip backing feels more stable.
A. It may be canceled in severe weather, with updates posted on the city website and the event’s official social media (Koga City). Mobile networks can get congested, so taking a screenshot of the latest post before you go can make it easier to check onsite.
A. Toilets on the riverbed can get crowded, so checking their locations right after you arrive helps. For families, putting a noticeable hat on kids and deciding a clear meeting point makes moving around easier.
A. The riverbed has few buildings to block views, which makes it good for shooting (Koga City Tourism Association). Rather than relying only on night mode, lowering exposure slightly and using burst shots often reduces misses and captures water reflections too.
