Yokosuka Friendship Day Fireworks 2023 (Yokosuka Kaikoku Hanabi Taikai): A Spectacular Tribute to US-Japan Relations

Welcome to the “Yokosuka Friendship Day Fireworks 2023,” known in Japanese as “よこすか開国花火大会2023 (Yokosuka Kaikoku Hanabi Taikai 2023).” This annual event is a highlight in Yokosuka City, located in Kanagawa Prefecture.

Yokosuka holds a special place in history. It’s where Commodore Perry of the United States set foot in 1854, marking a significant turn in Japan’s journey, opening its doors to the world. This event is not just a celebration of that pivotal moment but a symbol of the enduring friendship between Japan and the US.

Furthermore, the US military base in Yokosuka joins in this celebration. Every year, they host the “Friendship Day,” opening the base to the public and culminating in the grand fireworks display. Join us in commemorating this bond and witnessing the spectacular show!

This year, the festival promises to be grander than ever. From the usual 5,000 fireworks, we’re doubling the spectacle with approximately 10,000 fireworks, making it one of the largest displays on the Miura Peninsula!
