Part of the Mito Komon Festival, this show launches about 5,000 shells over Senba Lake in the middle of Mito City, with the water doubling every burst as a mirror. It is a manageable, city-scale festival — big enough for two-shaku-class shells and music-synced starmines, small enough that you can arrive at dinnertime and still find a lakeside spot.

Planning for 2027

The 2026 edition of Mito Kairakuen Fireworks Festival (Mito Komon Festival) was held on Sat, Jul 25. It is usually held on a Saturday in late July, as part of Mito Komon Matsuri. The organiser sets each year's date itself, so treat that as a planning window and confirm it before you book anything fixed.

The 2027 date has not been published yet. This page is re-checked against the official source and updated as soon as it appears, so it is worth a look again before you book anything non-refundable.

Background

The Mito Komon Festival honors the city's famous Edo-period lord Tokugawa Mitsukuni (the 'Mito Komon' of TV drama fame), and the lakeside fireworks night has been its summer centerpiece for over 60 years.

Getting there

Senba Lake is a 15-minute walk south of JR Mito Station (Joban Line limited express, about 75 minutes from Tokyo/Ueno). The whole lake perimeter functions as the viewing area.

Tips

The west bank facing the launch pontoons gives the closest view; the east side pairs the bursts with their reflection for photos.
It's an easy day trip from Tokyo — trains back to Ueno run late enough that lodging isn't necessary.
Rain slides it to the following evening rather than cancelling, unusual for a mid-size festival.
Combine with Kairakuen garden at sunset — one of Japan's three great gardens is a short bus ride away.
