Lake Biwa (琵琶湖) is Japan's largest lake, covering 670 km² and holding 20% of Japan's freshwater. The lake has sustained life for 4+ million years, making it one of the world's oldest lakes. Lake Biwa provides drinking water for 14 million people in Kansai region and serves as recreational hub for boating, fishing, cycling, and beach activities.

The lake's scale creates inland sea atmosphere — shoreline stretches 235km with beaches, ports, wetlands, and mountains. The combination of water activities, Mt. Hiei views, cycling routes, and accessible location makes Lake Biwa popular day-trip destination.

Insider Guide

Premium

**Biwaichi cycling:** The 235km lakefront cycling route (nicknamed Biwaichi, 'around Biwa') is Japan's premier long-distance cycling course. The route is 90% dedicated bike paths with clear signage, rest stops every 10–15km, and bike-friendly accommodations. Most cyclists complete it in 2–3 days (75–120km/day), staying in lakeside hotels. Single-day rides (150–200km) are possible for experienced cyclists starting at dawn. Rent bikes in Otsu or Hikone (¥1,500–3,000/day for sport bikes). **Lake cruise value:** The 80-minute cruise from Otsu Port provides water perspective of Mt. Hiei, Otsu cityscape, and lakefront villages. The experience is scenic but slow-paced (tourist-oriented narration, dated boat interior). Better value: rent a small boat or kayak (¥3,000–5,000/2 hours) for self-guided lake exploration with more freedom and engagement. **Best lakefront areas:** Omimaiko Beach (near Omi-Maiko Station) offers widest sand beaches and swimming areas (July–August only). Shirahige Shrine's torii gate standing in the lake creates iconic photo opportunity (accessible from shore). Omihachiman's historic canal district combines lake access with traditional architecture.
