In Mukojima, a little up from Asakusa and on the other side of Sumida River, a stone lantern or "joyato" (常夜燈) from the Edo period, marks the spot where Ushijima Jinja (牛嶋神社), a shrine that has now been moved further down the road and the Takeya Passage (竹屋の渡し) used to be; the passage was used by ferry boats bringing visitors from the part of Edo/Tokyo west of the river. Nowadays, the people pass using the bridges (the nearest one is Sakura-bashi/桜橋) but the joyato remains as a reminder that Mukojima was then, as it remains today, one of the best spots to see the cherry-trees in the spring, the fireworks in the summer and the geisha anytime.
