Thought it’s in Osaka, it’s one station from Kyoto by JR Special Rapid.
“A good place to get away from people”
Walk along the river. Go to the left. Don’t cross the bridge. You will cross the bridge when you go back. On the way back, cross the bridge, pass a bathtub, turn left, there will be a bus stop.
A good place for long exposure photograph. Image belows are from testing ND1000 and ND2-32 filters on a mobile phone camera (Samsung S20 Ultra, uneditted).
