Thank you kkday for this product; it makes booking a trip to Chikubu Island in Lake Biwa very easy. I booked a round trip from Imazu Port to Chikubu Island. Traveling from Kyoto, I transferred to the Kosei Line at Yamashina Station and got off at Omi-Imazu Station. It's about a five-minute walk to Imazu Port, very easy to reach. There were very few foreign tourists, making it a rare and relaxing trip. Perhaps in the future I'll consider traveling from Imazu Port to Chikubu Island, then disembarking at Nagahama Port, taking the JR train around the east shore of Lake Biwa, and then transferring to public transportation back to Kyoto. Traveling by public transport is itself part of a wonderful trip.
