What do you do on a Sunday...?
I liked this photo, called "Playing by the River" (川遊ぶ Kawa asobu) on the Hidaka sightseeing website.
Near Koma station, there is a special place called Kinchakuda. Now, in the middle of September, bright red lilies of the Lycoris radiata species can be seen there in all their brief splendour. The river is Kamagawa, and Kinchakuda is a name that refers to she shape of the route of the river, as it looks like a silk purse (Kinchaku).
