The most popular way to explore Lake Biwa is by bicycle, as the 200-kilometer circumference route, known as Biwaichi, is well-marked and mostly flat, making it suitable for cyclists of varying skill levels. Most riders complete the circuit in one to two days with overnight stops in lakeside towns. Alternatively, the JR Kosei Line runs along the western shore while the Keihan Ishiyama Sakamoto Line serves the eastern side, allowing visitors to explore different areas by train. Rental bicycles are available at major stations including Otsu, Hikone, and Nagahama.
