Lake Biwa’s 40th Fireworks Festival
One of Kansai’s most famous fireworks spectacles returns on August 6, 2026 as the Lake Biwa Great Fireworks Festival once again draws massive crowds from Osaka, Kyoto, and across the region to Otsu for panoramic lakefront fireworks, mountain reflections, and one of Japan’s great summer night traditions.
Every summer, long before sunset, trains departing Osaka and Kyoto gradually fill with people carrying picnic bags, folding fans, cameras, and summer festival clothing as crowds head north toward the shores of Japan’s largest lake. The destination is Otsu City in Shiga Prefecture, where the Lake Biwa Great Fireworks Festival returns on August 6, 2026 for its milestone 40th anniversary edition — one of the region’s biggest and most visually dramatic summer fireworks nights.
Even though the festival is technically outside Osaka Prefecture, Lake Biwa Fireworks has long functioned as part of the broader Kansai summer tradition for Osaka residents. The trip from central Osaka to Otsu takes less than an hour by train, making the event feel less like a distant destination. For many people living in Osaka, attending the Lake Biwa fireworks is a yearly excursion tradition.
The Lake Biwa fireworks unfold above an enormous open lake framed by dark mountain silhouettes and broad panoramic skies. Fireworks reflections stretch across the water while launches erupt from multiple positions near the Otsu lakeshore, creating a scale and depth difficult to replicate anywhere else in Kansai. The visual atmosphere feels expansive in a way that Osaka’s urban fireworks rarely can.
The practical rhythm of the day also feels different from a normal city fireworks event. Visitors arrive gradually throughout the afternoon from Osaka-Umeda, Kyoto, Kobe, and surrounding areas before spreading across the lakeshore around Otsu Port, Biwako-Hamaotsu, and nearby waterfront areas. Some secure official paid seating sections well in advance, while others search for free or unofficial lakeside viewing spots farther from the controlled zones. Hotels, cruises, restaurants, and train stations throughout Otsu become part of the event atmosphere as the city transforms into one of Kansai’s largest temporary summer gathering spaces.
Recent editions have featured approximately 10,000 fireworks launched over the water during a tightly choreographed one-hour program that combines large shells, wide starmines, and expansive panoramic effects designed specifically for the lakefront setting. The reflections across the surface of Lake Biwa are part of the spectacle itself, creating layered compositions where explosions fill both the sky and the water simultaneously. For photographers, couples, families, and longtime Kansai fireworks fans, that scenery is part of what makes the event feel fundamentally different from the region’s urban hanabi festivals.
The festival itself has evolved into a highly organized large-scale operation. Official paid seating now forms a major part of the experience, with controlled viewing areas, reserved camera sections, smartphone-based electronic ticketing, route restrictions, and extensive crowd-management systems spread throughout the waterfront.
For Osaka visitors this is one of the defining summer outings of the Kansai fireworks season.

THE SCENE: FAQ’s
ACCESS
Where is the Lake Biwa Great Fireworks Festival held?
The festival takes place along the Lake Biwa waterfront in Otsu City, Shiga Prefecture, centered around the Otsu Port and Biwako-Hamaotsu area.
Main viewing zones spread along the lakeshore surrounding Otsu Port, with both official paid seating areas and unofficial/free viewing areas extending across nearby waterfront sections.
Although the event is held in Shiga Prefecture, it is widely considered part of the broader Kansai summer fireworks tradition for Osaka residents because of its easy train access and longtime regional popularity.
How do I get there from Osaka City?
The easiest route from central Osaka is usually:
Osaka Metro → JR Osaka Station → JR Kyoto Line / Biwako Line → Otsu Station
Most visitors coming from Osaka first connect from Osaka Metro lines into JR Osaka Station before taking JR trains toward Kyoto and Otsu.
Typical transfer examples include:
Osaka Metro Midosuji Line → Umeda Station → walk to JR Osaka Station
Osaka Metro Tanimachi Line → Higashi-Umeda Station → walk to JR Osaka Station
Osaka Metro Yotsubashi Line → Nishi-Umeda Station → walk to JR Osaka Station
From JR Osaka Station, many trains continue directly onto the Biwako Line without requiring a transfer in Kyoto.
Travel time from Osaka to Otsu is typically around 40–45 minutes depending on train type and congestion.
What are the nearest stations?
JR Kyoto Line / Biwako Line → Otsu Station
Approximately 15–20 minutes on foot depending on the viewing area.

Very close to the lakeshore viewing areas, though this station becomes extremely congested before and after the fireworks.

INFO & TIPS
Is photography popular at the event?
Very much so.
The Lake Biwa Great Fireworks Festival is considered one of Kansai’s premier fireworks photography events because of:
- wide lake reflections
- mountain silhouettes
- panoramic launch spacing
- large-scale waterfront compositions
- open skies above Japan’s largest lake
Dedicated camera seating sections have been offered in recent editions for photographers using tripods and professional equipment.
What makes Lake Biwa different from Osaka’s fireworks festivals?
Unlike Osaka’s urban river fireworks events, Lake Biwa offers a much broader panoramic setting built around open water, reflections, mountain backdrops, and expansive skies rather than dense city skylines.
The atmosphere feels more like a regional summer excursion than a neighborhood city festival.
Why do so many Osaka residents go to this event?
Even though the festival is held in Shiga Prefecture, the event has long been part of the broader Kansai summer tradition for Osaka residents because Otsu is easily accessible from Osaka by train in under an hour.
For many people in Osaka, attending Lake Biwa Fireworks is treated as a seasonal summer trip rather than simply another local fireworks show.
Is the event family friendly?
Yes. Families, couples, photography enthusiasts, and longtime fireworks fans all attend the festival. However, the scale of the crowds can be overwhelming for very small children late at night around stations and major exit routes.
What should visitors bring?
Recommended items include:
- drinks and hydration supplies
- portable fans or cooling items
- picnic sheets for unofficial viewing areas
- rain gear
- portable phone chargers
- comfortable walking shoes
Visitors attending unofficial/free viewing areas should also prepare for long periods of waiting and limited personal space.
What should visitors wear?
August evenings around Lake Biwa remain hot and humid even after sunset. Lightweight summer clothing is strongly recommended.
At the same time, visitors should prepare for long walking distances and heavy crowds around stations and waterfront areas.
Are drones allowed?
Visitors should follow all official safety regulations and operational restrictions announced by organizers. Drone use near large Japanese fireworks festivals is typically heavily restricted or prohibited for safety reasons.
Are cruises or hotels part of the experience?
Yes.
Many visitors turn the event into a full overnight Kansai summer trip by:
- booking hotels in Otsu or Kyoto
- reserving lakefront restaurants
- joining sightseeing cruises
- staying after the fireworks to avoid peak train congestion
For many attendees, the broader lakeside atmosphere is part of the appeal of the event itself.
What is the biggest challenge of attending?
Crowds and transportation.
The area around Otsu Station, Biwako-Hamaotsu Station, and the lakeshore becomes extremely congested before and especially after the fireworks. Visitors should expect:
- long station queues
- slow walking routes
- crowded trains back toward Kyoto and Osaka
- heavy congestion throughout the waterfront district
Planning transportation in advance is strongly recommended.
