Stretching across the heart of Shiga Prefecture, Lake Biwa (Biwako) is Japan's largest freshwater lake and one of the oldest lakes in the world. More than four million years old, the lake has shaped the history, culture, economy, and spiritual traditions of central Japan for thousands of years. Today, it remains one of Kansai's most rewarding destinations, offering historic castles, sacred islands, lakeside towns, scenic cruises, cycling routes, beaches, and mountain views—all within easy reach of Kyoto and Osaka.
Despite its size and historical importance, Lake Biwa is often overlooked by international visitors. Those who venture beyond Japan's famous cities are rewarded with a destination where ancient temples, samurai history, nature, and local culture come together in a way few places can match. Whether you're planning a relaxing day trip, an outdoor adventure, or a deeper exploration of Shiga Prefecture, Lake Biwa offers experiences for every type of traveller.
Where is Lake Biwa?
Lake Biwa is located in Shiga Prefecture, immediately east of Kyoto in Japan's Kansai region. Covering approximately 670 square kilometres, it occupies nearly one-sixth of the prefecture and supplies drinking water to more than 14 million people, including residents of Kyoto and Osaka.
Thanks to its convenient location, Lake Biwa is easily reached by rail from many of Japan's major cities. Kyoto is less than 15 minutes from the southern lakeshore, while destinations such as Nagahama and Hikone in northern Shiga can be reached in around one hour. Visitors travelling from Nagoya can also access the lake quickly via the JR Tokaido Line and Shinkansen connections.
The lake is surrounded by historic towns, scenic mountains, temples, shrines, and recreational areas, making it an ideal destination for day trips as well as longer stays.
Why Visit Lake Biwa?
One of the World's Oldest Lakes
Lake Biwa is estimated to be more than four million years old, making it one of the oldest lakes on Earth. Its remarkable age has allowed a unique ecosystem to develop, with dozens of endemic species found nowhere else in the world. The lake has also supported human communities for thousands of years, shaping the history of the Kansai region long before Kyoto became Japan's imperial capital.
The Heart of Shiga Prefecture
Life in Shiga has always revolved around Lake Biwa. For centuries, the lake served as an important transportation route connecting eastern and western Japan, while its waters supported fishing communities, agriculture, commerce, and religious pilgrimage. Even today, the lake remains central to daily life, providing drinking water, recreation, and countless opportunities for sightseeing.
Easy to Explore from Kyoto and Osaka
One of Lake Biwa's greatest advantages is its accessibility. Visitors staying in Kyoto or Osaka can reach many of the lake's highlights in less than an hour, making it one of the easiest day-trip destinations in the Kansai region. Whether you're interested in history, hiking, temples, cycling, or simply escaping the city, Lake Biwa offers an excellent alternative to Japan's more crowded tourist destinations.
The History of Lake Biwa
Lake Biwa has influenced Japanese history for thousands of years. Long before written records, its shores were home to early settlements that depended on the lake for food, transportation, and trade. During Japan's ancient and medieval periods, the lake became an important route linking Kyoto with eastern Japan, helping merchants, monks, nobles, and military leaders travel across the country.
The lake also played an important spiritual role. Sacred mountains, islands, and springs surrounding Lake Biwa became centres of both Shinto worship and Buddhism. Chikubu Island emerged as one of Japan's most important religious sites, while nearby Mount Hiei became the home of Enryaku-ji, one of the country's most influential Buddhist monasteries.
During the Sengoku (Warring States) period, control of Lake Biwa meant control of key transportation routes. Powerful figures including Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu all recognised the region's strategic importance. Castles such as Hikone Castle and Nagahama Castle were built to protect trade routes and demonstrate political power, leaving behind a rich samurai heritage that visitors can still explore today.
The Best Things to Do Around Lake Biwa
Whether you're interested in history, nature, outdoor adventure, or traditional culture, Lake Biwa offers something for every type of traveller. From National Treasure castles and sacred islands to mountain viewpoints and charming lakeside towns, the region is filled with rewarding day trips that are easily reached from Kyoto, Osaka, and Nagoya.
Visit Chikubu Island
One of Lake Biwa's most unforgettable destinations is Chikubu Island (Chikubushima), a sacred island that has welcomed pilgrims for more than 1,300 years. Home to Hōgon-ji Temple and Tsukubusuma Shrine, the island is accessible only by ferry and combines beautiful lake scenery with centuries of religious history.
Explore Hikone Castle
Designated a National Treasure, Hikone Castle is one of only twelve original castles remaining in Japan. Climb the historic keep, walk through its impressive defensive gates, and enjoy panoramic views across Lake Biwa before exploring the beautifully preserved castle town below.
Discover Nagahama
Founded by Toyotomi Hideyoshi, Nagahama is one of northern Shiga's most attractive towns. Wander the historic streets of Kurokabe Square, browse local shops and cafés, visit Nagahama Castle, or use the town as your gateway to Chikubu Island.
Visit Shirahige Shrine
The floating torii gate of Shirahige Shrine is one of Lake Biwa's most photographed landmarks. Standing just offshore, it appears to rise directly from the water and is particularly beautiful at sunrise and sunset.
Ride the Ropeway to Biwako Valley
High above the western shore of the lake, Biwako Valley offers spectacular views from Biwako Terrace, one of Kansai's most famous scenic viewpoints. Visitors can enjoy hiking in the warmer months and skiing or snowboarding during winter.
Discover Local Food and Culture
No visit to Lake Biwa is complete without experiencing Shiga's local cuisine. Try famous Omi Beef, sample traditional freshwater fish dishes such as funazushi, enjoy regional sake, or explore historic towns where centuries-old food traditions continue today.
Visit Lake Biwa Museum
Located in Kusatsu, the Lake Biwa Museum is one of Japan's leading freshwater museums. Interactive exhibits explore the lake's four-million-year history, unique wildlife, archaeology, and the relationship between Lake Biwa and the people who have lived along its shores for thousands of years. It's an excellent stop for families and anyone interested in understanding the lake beyond its scenic beauty.
Experience Lake Biwa by Boat
Lake Biwa has served as an important transportation route for centuries, and today one of the best ways to appreciate its size and beauty is from the water. Whether you're visiting sacred islands, enjoying a leisurely sightseeing cruise, or travelling between lakeside towns, a boat trip offers a unique perspective of Japan's largest freshwater lake.
Several different cruise experiences are available throughout the year:

Outdoor Activities Around Lake Biwa
Lake Biwa is one of western Japan's premier outdoor recreation destinations, offering activities throughout the year for visitors of all ages.
Cyclists from around the world travel to Shiga to complete Biwaichi, the approximately 200-kilometre route that circles Japan's largest lake. While some riders complete the entire circuit over several days, shorter sections are ideal for casual cyclists wanting to experience the lakeside scenery.
During spring and summer, the lake becomes a playground for outdoor enthusiasts. Popular activities include kayaking, canoeing, stand-up paddleboarding (SUP), sailing, fishing, and lakeside camping. Omi-Maiko Beach is one of the region's most popular swimming areas, offering clear water, sandy beaches, BBQ facilities, and family-friendly campsites.
In the colder months, Biwako Valley transforms into one of the Kansai region's best ski and snowboard resorts. Even outside the snow season, its ropeway, hiking trails, and Biwako Terrace provide breathtaking panoramic views across the lake and surrounding mountains.
