Lake Biwa Travel Guide: Japan’s Ancient Waters

Japan is often defined by its frantic neon capitals or its quiet, misty mountains. But somewhere between the rush of Kyoto and the rural heartland lies a body of water so vast it feels like an inland sea. This is lake biwa, the largest freshwater lake in Japan and one of the oldest lakes in the world. For travelers weary of the typical "Golden Route" tourist traps, this region offers a refreshing plunge into authentic Japanese culture, history, and nature.

Having spent time cycling its perimeter and exploring its sleepy lakeside towns, I’ve found that Lake Biwa isn't just a scenic spot; it is the lifeblood of the Kansai region. It supplies water to millions, yet retains a spiritual quietness that is hard to find elsewhere. Whether you are a history buff chasing the footsteps of samurai or an outdoor enthusiast looking for the perfect cycling route, this guide will help you navigate the wonders of Shiga Prefecture’s crown jewel.

Why Lake Biwa Matters: More Than Just Water

To understand the significance of this lake, you have to look at the timeline. Scientists estimate that lake biwa is approximately 4 million years old. This places it in an elite club of "ancient lakes," alongside Lake Baikal and Lake Tanganyika. Because of its isolation and age, it has become an evolutionary laboratory. There are over 60 endemic species here—fish and mollusks that exist nowhere else on Earth.

But beyond biology, the lake is historically pivotal. Its proximity to Kyoto (just a 10-minute train ride away) meant that for centuries, it served as a critical transportation hub. Rice, salt, and fish were ferried across its waters to feed the imperial capital. When you walk the streets of towns like Omihachiman or Hikone, you aren't just seeing old buildings; you are walking through the legacy of the wealthy Omi merchants who built their fortunes on these waters.

The Spiritual Heart: Chikubushima

One of my most vivid memories of the region was taking a ferry from Nagahama to Chikubushima. It’s a small, uninhabited island that feels miles away from the modern world. As the boat cuts through the dark blue water, the island rises steeply, covered in dense green foliage.

Chikubushima is known as a "Power Spot" in Japan—a place of concentrated spiritual energy. It is home to the Hogon-ji Temple and Tsukubusuma-jinja Shrine. Climbing the steep stone steps to the temple, the air smells of incense and damp earth. The architecture here is stunning, particularly the Karamon Gate, which is a National Treasure. Legend has it that the island is the dwelling place of the Benzaiten, the goddess of everything that flows: water, words, music, and wealth.

Visitors often participate in kawarake nage here. You purchase small clay discs, write a wish on them, and try to throw them through a specific torii gate overlooking the water. It’s harder than it looks—the wind off the lake is tricky—but watching your wish sail out toward the horizon is a strangely satisfying ritual.

Cycling the "Biwaichi"

For the active traveler, the best way to experience the scale of lake biwa is on two wheels. The route is known as "Biwaichi," a roughly 200-kilometer loop around the lake. It has been designated as a National Cycle Route, meaning the infrastructure is excellent. Blue lines painted on the
