Hokkaido: Lake Shikaribetsu railway line

I went to see the underwater railway tracks at Lake Shikaribetsu, which is within a day's drive from Obihiro, Hokkaido. I love eastern Hokkaido and go there every year, and my destinations are becoming less and less standard, but I found it on social media and went there. The railway tracks at the bottom of the lake. It's not an abandoned line, but it seems to be a railway track for lifting pleasure boats onto land. #summerweekendtrip #hokkaidotrip #keihangroupcampaign
