Fish for carp in the city, no gear needed
A tsuribori is a fishing pond stocked with fish, where you pay by the hour to fish. Rods and bait are rented on site, so you can walk in empty-handed, sit by the water and watch your float, whether or not anything bites. No experience is needed, so it makes an easy, quiet break between sightseeing stops.
A fishing pond right beside Ichigaya Station, set in the old outer moat of Edo Castle, where trains run past along the water as you fish. Rent a rod and bait and fish for carp; no booking is needed. The fish must be released, so you cannot take them home.
A fishing pond surrounded by trees inside Wadabori Park, a large green park in a residential part of western Tokyo. Rent a rod and bait and spend a slow hour by the water. It is closed on Tuesdays.
