Introduction

Cycling the southern part of Lake Biwa reveals a stunning interplay of water and mountains—capturing the essence of Japan’s natural beauty. Starting and finishing at RBRJ (Lake Biwa), this 55 km loop blends sections of the official Biwaichi cycling route with detours into the quiet farmlands and rolling hills of Shiga. It’s a rewarding half-day ride best suited for experienced cyclists looking to explore beyond the beaten path.

Shiga may not be a well-known prefecture, but its peaceful scenery and rich historical sites quickly show why it’s one of Japan’s best-kept secrets.

Since opening RBRJ (Lake Biwa), we are discovering that there are a lot more cycle routes in Shiga, than the national cycle route of Biwaichi. The RBRJ Lake Biwa Southern Loop offers a nice balance of following the Biwaichi blue chevrons blended with more remote areas away from the blue markings. This route is perfect for those looking for a cycling adventure beyond Shiga’s main attraction but still wanting to see the sights of the southern area of the lake.

Route Highlights

Seta-no-Karahashi To the Lake Biwa museum

Starting from RBRJ Lake Biwa, ride across Seta no Karahashi, a historic bridge with deep cultural significance. This is also the official starting point of Biwaichi, the full cycling loop around Lake Biwa. From here, dedicated cycling lanes guide you along the lakeside.

After cycling about 15 km, with scenic views of Lake Biwa framed by mountain ranges, you’ll arrive at the Lake Biwa Museum. The museum features one of Japan’s largest freshwater aquariums, showcasing rare species found in Lake Biwa and other parts of the world.

Lake Biwa Cyclists’ Sanctuary Monument

After the museum, you’ll turn right and follow the path next to the Yamaga River to the Melon Kaido. Cycling through the flat and serene farmlands along the Melon Kaido. At the end of the Melon Kaido, you’ll pass through the Biwako Forest of Global Citizens before reaching the Lake Biwa Cyclists’ Sanctuary monument. The Cyclists’ Sanctuary Monument by Lake Biwa is a scenic photo spot with a stunning view behind it. It’s the perfect place to take a commemorative photo when cycling around Lake Biwa.

Lake Biwa Ohashi

After visiting the monument, you’ll make your way to the Lake Biwa Ohashi. Lake Biwa Ohashi is a 1.4-kilometer bridge that connects the cities of Otsu and Moriyama in Shiga Prefecture. The observatory on the bridge offers breathtaking panoramic views of Lake Biwa and the surrounding mountains, making it a memorable highlight of any Biwaichi journey. Also, listen out for the melody of the “Biwako Shuko no Uta” (Lake Biwa Rowing Song) as vehicles drive over the bridge. This is achieved by grooves cut into the road surface that create musical notes as vehicles drive over them at the designated speed. Very Clever!

Above Sakamoto

After crossing Lake Biwa Ohashi, make your way through Katata, over to pick up Route 313. The blue cheverons will lead you as you ascend the hills north of Sakamoto. After a quick but fun forest ascent and descent, the route leads to Saikyo-ji and Hiyoshi Taisha at the foot of Mt. Hiei.
It is the head shrine of over 3,800 Hiyoshi shrines across Japan, known for its National Treasure hall, vibrant autumn foliage, and unique guardian monkeys called Masaru, which are believed to bring good fortune.

The scenic mountain road in the surrounding area is lined with refreshing greenery, making the ride especially pleasant. This area is a real gem, offering a tranquil escape and a rich cultural experience that even gets overlooked by locals.

Omi Jingu & Miidera

A little further along the route, you’ll arrive at Omi Jingu Shrine, dedicated to Emperor Tenji, who introduced Japan’s first water clock.
The shrine is deeply connected to Hyakunin Isshu poetry and is well known as a key setting in the popular manga and anime Chihayafuru. The vivid vermilion buildings and peaceful forest setting make it a beautiful and culturally rich stop.

After Omi Jingu, you’ll descend down to Miidera Temple, one of Shiga’s most historic and culturally significant temples, renowned for its National Treasure main hall and deep spiritual legacy. Nestled at the foot of Mt. Hiei, it’s especially beloved for its spectacular cherry blossoms in spring and vibrant autumn foliage, making it a popular destination year-round for both pilgrims and seasonal visitors.

Returning to RBRJ (Lake Biwa)

Dropping back through Otsu to the shoreline, you’ll pass Lago, a newly opened restaurant in April 2025, offering a refined dining experience with stunning views of Lake Biwa. In addition to its beautiful setting and great food, you can also find famous traditional Japanese sweets here, perfect for souvenirs. Take home a piece of Japan’s sweet heritage to share with loved ones or as a treat for yourself.
