The "古河花火大会" (Koga Fireworks Festival), held in 古河市 (Koga City), 茨城県 (Ibaraki Prefecture), is one of the largest fireworks festivals in the Kanto region. It is particularly renowned for launching two of Japan's largest "三尺玉" (San-shaku-dama) fireworks, which open to an impressive diameter of approximately 650 meters, captivating spectators with their overwhelming power. Set against the expansive banks of the 渡良瀬川 (Watarase River), a magnificent display of fireworks, including extra-large wide starmines, illuminates the night sky for about 70 minutes.

Highlights of the Fireworks Festival

The greatest appeal of the Koga Fireworks Festival lies in its dynamic presentation, leveraging the expansive location of the Watarase River riverbed. The following two points are particularly noteworthy:

Kanto's Largest "Sanjakudama" Lights Up the Night Sky

The "Sanjakudama" (三尺玉, three-shaku shell), weighing approximately 300 kg (660 lbs) with a diameter of about 90 cm (3 feet), is synonymous with the Koga Fireworks Festival. Launched approximately 600 meters (1,970 feet) into the sky, this massive firework blooms into a grand flower with a diameter of about 650 meters (2,130 feet), overwhelming spectators with its scale. According to official announcements, the program is scheduled to feature two of these magnificent Sanjakudama. The thunderous roar and the shower of light filling the night sky will undoubtedly be an unforgettable experience.

"Tokudai Wide Star Mine" Synchronized with Music

Another major highlight of the Koga Fireworks Festival is the "Tokudai Wide Star Mine" (特大ワイドスターマイン, Super Large Wide Star Mine), designed by Nomura Hanabi Kogyo Co., Ltd. (野村花火工業株式会社), a leading company in the fireworks industry, to utilize the venue's unique terrain. Hundreds of fireworks are launched in rapid succession, synchronized with music, spreading horizontally across the night sky in a dazzling display. The ultra-large wide star mine that concludes the festival is breathtakingly beautiful, promising to create a truly moving summer memory.

Venue and Map

The venue for the Koga Fireworks Festival is 古河ゴルフリンクス (Koga Golf Links) (渡良瀬川河畔 - Watarase River banks), located at 10-1 Nishimachi, Koga City, Ibaraki Prefecture. As it is a spacious riverbed, there are few buildings obstructing the view, making it relatively easy to see the fireworks.

Access

Using public transportation is highly recommended for accessing the Koga Fireworks Festival venue.

  • Access by Train

    • From JR宇都宮線 (JR Utsunomiya Line) 古河駅 (Koga Station): The venue is approximately a 20-minute walk. Along the way from the station, numerous food stalls line the streets, allowing you to enjoy a festive atmosphere as you head to the venue.

    • Notes on Crowds: Both stations will be extremely crowded on the day of the festival.

Hidden Gems

The area around the venue can be extremely crowded, so consider these hidden spots where you can enjoy the fireworks comfortably from a slightly more distant location.

Watarase River Embankment near Shin-Koga Station

This spot is relatively close to the launch site, allowing you to enjoy the full scope of the wide starmines. Access from 新古河駅 (Shin-Koga Station) is excellent, and it tends to be less crowded than the Koga Station side. While lower-altitude fireworks might be harder to see, the impact is still substantial.

Riverbed Downstream from the Venue

The riverbed slightly away from the paid seating area offers more space and is less crowded than the main venue. If you arrive early and spread out a leisure sheet, you can comfortably watch the fireworks.

古河公方公園 (Koga Kubo Park) (古河総合公園 - Koga Sogo Park)

This is a recommended spot for families with small children. You can relax in the spacious grounds while enjoying the fireworks.

渡良瀬遊水地 (Watarase Retarding Basin)

Although a bit of a distance from the venue, this spot is recommended for those who want to enjoy the fireworks leisurely in a wide-open space.

Around AEON Koga Store

The rooftop parking lot of イオン古河店 (AEON Koga Store) is also cited as a hidden gem. While it's further from the venue, you can get a good view of the fireworks, and the advantage is easy access to food and restrooms. However, please note that it may not always be freely accessible.

Along 十間道路 (Jikken Doro Road)

Known as a point where you can avoid crowds and enjoy a clear, unobstructed view of the fireworks.

What to Bring & Attire

Even on a summer night, the riverbed can be breezy and get chilly. To ensure a comfortable fireworks experience, prepare the following:

  • Leisure Sheet / Cushion: Essential for sitting comfortably for extended periods.
  • Insect Repellent: Mosquitoes can be prevalent near the river.
  • Light Snacks & Drinks: While food stalls will be available around the venue, they can get crowded, so preparing some items beforehand is a good idea.
  • Light Jacket or Cardigan: Nights can get cool, so a light layer is recommended.
  • Rain Gear: In case of sudden weather changes, a raincoat is preferable to an umbrella as it won't obstruct others' views.
  • Trash Bags: Please take all your trash with you.

Nearby Dining & Sightseeing

Before or after the fireworks festival, take the opportunity to explore the charms of Koga City. Known as "Ibaraki's Little Kyoto," Koga is a city rich in history and culture.

  • Immerse yourself in history at the Koga Historical Museum (古河歴史博物館) or the Tenkoku Museum (篆刻美術館).
  • Stroll through the streets that retain the atmosphere of a prosperous post town from the Edo period.
  • Enjoy a meal at local restaurants. On the day of the fireworks, establishments like Denny's Koga Store (デニーズ古河店) in the vicinity are also available.
