Hot Air Balloon and Moomin

Moomin Day fireworks and celebrations annually on August 9th.

In 2019, Metsa Village had a popular fireworks called Forest and Lake and Fireworks. It may have become an annual event had it not been for the pandemic. They did actually have a variation of the event in 2020, but they had to cancel it in 2021. The fireworks came back in 2022, but with a new name. And going forward, they will now be on annually on August 9th for Moomin Day. The tickets for the 2023 event are on sale now (July 11th 2023). Moreover, this year (2023) there are also free “Saturday night fireworks” on select dates.

Miyazawa Lake site of the Metsa fireworks 2020

Metsa is located by the Miyazawa lake which is one of Saitama’s scenic Autumn leaf viewing locations. We timed it wrong last year, and missed the vibrant colors. However, Metsa is always picturesque thanks to the lake and forest. But adding fireworks to that combination will make for an Autumn night to remember!
