Lake Biwa is not simply a large lake. At 670 square kilometres, it is Japan’s largest body of freshwater, and its shores have been inhabited, crossed, worshipped, and fought over for at least fourteen centuries. The lake predates the oldest surviving structures on its banks; its name derives from the biwa lute, whose shape the water body loosely resembles when viewed from the surrounding mountains. For overseas visitors who know Shiga at all, they tend to know it as the prefecture that contains Lake Biwa — and they are right to think of the lake first, because everything in Shiga orbits around it.

The access story is one of Japan’s best-kept secrets. Otsu, Shiga’s prefectural capital and the lake’s southern gateway, is just eight minutes from Kyoto Station by JR Biwako Line (¥240). From Osaka, the journey to Otsu takes around 40 minutes. The combination of extraordinary proximity to two of Japan’s most visited cities and a landscape that feels genuinely apart from them makes Lake Biwa a logical half-day or full-day addition to any Kansai itinerary.

Understanding the Lake

Lake Biwa divides roughly into a large northern basin and a smaller, shallower southern section separated by a narrow neck of water near the city of Moriyama. The northern basin contains the most dramatic scenery: wider expanses of open water, the Biwako Valley mountains to the west, the Suzuka Range to the east, and the sacred island of Chikubu floating offshore. The southern basin is calmer, more accessible from Otsu and Kyoto, and home to several of the lake’s most photographed landmarks.

The lake’s ecology is ancient. Several fish species — including the endemic nigorobuna crucian carp used in funazushi fermented sushi — have evolved in Biwa’s waters over millions of years and exist nowhere else on earth. The lake is treated as a living cultural landscape as much as a natural one. Understanding this context deepens a visit considerably.

Seasons on the Water

Each season offers a different relationship with the lake. Spring brings cherry blossoms along the lakefront promenades and clear water before summer algae. Summer is warm and bright, ideal for cruises and cycling, though crowds peak in late July and August. Autumn brings the most dramatic light: low sun over the water, changing colours on the western mountains, and the start of winter mist season in late November. Winter fogs on Lake Biwa are dense and mythologically resonant — the lake disappears into white silence and the shore feels genuinely isolated from the wider world.

Otsu and the Southern Lake

Otsu is the logical starting point for most visitors arriving from Kyoto. The city itself is often dismissed as merely functional, which is unfair — its lakefront Biwako Otsu area has a pleasant promenade, several notable historic temples, and the departure point for the main lake cruise.

Biwako Otsu Cruise

The Biwako Kisen cruise operates from the pier adjacent to Otsu Port, a ten-minute walk from JR Otsu Station. The standard cruise loops across the southern basin and returns without landing, taking approximately 50 minutes. Adult fare is ¥1,540. The view from the water is categorically different from the view from shore: the full width of the lake opens up, the Hira Mountains appear above the western bank, and the Otsu cityscape recedes into its correct proportions against the landscape behind it. Seasonal evening cruises and longer excursions to Chikubu Island in the north are also available; check the Biwako Kisen website for current schedules as they vary significantly by season.

Ishiyamadera Temple

A short distance south of central Otsu, Ishiyamadera is one of the most venerable Buddhist temples in the Kansai region. Founded in the eighth century, it houses Tang dynasty architectural elements and is celebrated above all for its literary connection: Lady Murasaki Shikibu is said to have begun writing The Tale of Genji here in the year 1004, inspired by the view of the lake from the temple’s rocky promontory. The rock itself — natural wollastonite that erupts dramatically from the temple grounds — is the reason for the name: Ishiyama, Stone Mountain. Entry is ¥600. The temple is accessible by Keihan Ishiyama-Sakamoto Line from JR Ishiyama Station in about ten minutes.

Hikone and the Eastern Shore

Hikone sits on the eastern shore of the lake, 45 minutes from Kyoto by JR Biwako Line (¥1,340 from Kyoto Station). The city is home to Hikone Castle, one of only twelve original surviving castle keeps in Japan and one of just four designated National Treasures — the highest designation in Japanese cultural heritage law. That designation places it alongside Matsumoto, Himeji, and Inuyama as one of the most significant castle structures in the country.

Hikone Castle

The castle donjon dates to 1622 and retains its original timber structure throughout. The climb through three interior floors is steep — the ladders are more vertical than staircase — but brief, and the view from the upper floor across the lake and the surrounding mountain ranges is among the finest castle views in Japan. Entry to the castle and garden is ¥800. The garden below the castle, Genkyuen, is a classical pond-stroll garden with a teahouse that operates during cherry blossom and autumn seasons. The castle is also associated with Hikonyan, a white cat mascot that performs at the castle grounds on a fixed schedule; the schedule is posted at the gate.

The castle sits on a hill directly above the lake shore, and the combination of stone walls, white plaster donjon, and water in the background produces one of Japan’s most photographed castle compositions, particularly in spring when the surrounding cherry trees bloom.

Shirahige Shrine and the North

The northern portion of the lake offers the Shirahige Shrine, whose orange torii gate stands directly in the lake water off the Makino coast, roughly 90 minutes from Kyoto by JR Biwako Line and Kosei Line (¥1,170 to Omi-Takashima Station, then 15 minutes by bus or taxi). The gate rises from the surface just offshore, backed by the wooded hillside above the shrine, and is most striking at sunrise when the light crosses the water from the east. The visual parallel with Miyajima’s famous Otorii gate is often made, but the setting here is quieter and the crowds far thinner. The shrine itself is dedicated to longevity and is one of the oldest in the Omi region.

Nagahama

Further north, Nagahama is a compact castle town with a well-preserved historic centre around Nagahama Station. The town is best known for Kurokabe Square, a cluster of former bank buildings and Edo-period merchant houses that have been converted into glass craft workshops, cafes, and specialty shops. The glass-blowing tradition here is genuine and the quality of work on display is high. Nagahama is approximately 70 minutes from Kyoto by JR Biwako Line and Kosei Line services (¥1,520).

Cycling Around the Lake

The full circuit of Lake Biwa — known as Biwako Cycling Road or Biwichi — covers 240 kilometres and is a serious undertaking requiring two days at a strong pace. However, individual sections of the route are excellent for day trips. The southern lake section from Otsu to Hikone along the eastern shore covers approximately 60 kilometres on well-marked dedicated cycling infrastructure and is manageable for a fit recreational rider in five to six hours. Bicycle rental is available at major stations including Otsu and Hikone, typically from ¥1,500 to ¥3,000 per day depending on bike type.

Omi Beef — the Lake’s Table

Omi beef is among Japan’s three historically pre-eminent wagyu brands, alongside Matsusaka and Kobe. Many Japanese connoisseurs consider Omi beef superior to its more internationally famous rivals — it has been supplied to the imperial court since the seventeenth century. The cattle are raised in the lake basin and fed on rice straw from the paddy fields that surround the water. Dedicated Omi beef restaurants cluster in Hikone and around the Otsu lakeshore area. A proper sukiyaki lunch in Hikone using Omi beef costs approximately ¥3,000 to ¥5,000 and constitutes one of the most genuinely distinctive culinary experiences in the Kansai region.

Practical Tips

From Kyoto, the JR Biwako Line is the primary access route; a single IC card covers the full eastern shore from Otsu to Nagahama. The Biwako Free Kippu pass (available at major JR stations in Kansai) covers unlimited travel within Shiga and includes entry discounts at several attractions; check current pricing at Kyoto or Osaka stations before travel. Hiring a car from Kyoto or Otsu is the most efficient approach for covering the full lake perimeter in a single day, particularly for reaching the less-served western shore.
