Konan in Shiga reflects the Shiga Prefecture Lake Biwa southern position adjacent to Konan Alps, with vehicle traffic on surrounding roads and the manufacturing, Miho Museum tourism, and agricultural corridor contributing local sources. Consistent Lake Biwa breezes provide natural ventilation, while the outstanding lake setting generally maintains Konan at moderate to good conditions for a Japanese Shiga Prefecture lakeside city throughout most of the year.
