Last weekend, after a long walk around Yokohama we ended up in a curious tower. It turns out that it is one of the tallest lighthouses in Tokyo bay (58 meters/192 feet tall), it has an observatory open to the public and it is surrounded by a park. Built in 1986, in the midst of the Japanese economic boom, with a sumptuous design for just being a simple lighthouse. I like the retrofuturistic halo that it has.
