Location

The closest station is Chiba-Minato Station on the Keiyō Line and Chiba Urban Monorail. It takes about 15 minutes on foot from the station to Chiba Port Tower. The tower is close to Chiba Central Post Office and Chiba Prefectural Museum of Art.

History

The tower opened on June 15, 1986. It was built in commemoration of the population of Chiba Prefecture exceeding five million in 1983. This is because the expansion of the commuter belt to Tokyo and the development of the Keiyō Industrial Zone had caused rapid growth in Chiba Prefecture's population from 1970s to 1980s.

Appearance

The tower cross-section is lozenge shaped. The size of lozenge is not so large because Chiba Prefecture wanted to emphasize the slimness of the tower. The length of a side of this lozenge is about 15 m (49 ft). On the outside, the tower is covered with mirrored glass which reflects the sun and makes the tower appear blue in fine weather.

At the top of the tower, there is a system called dynamic damper. It is about 15 tons and it moves in the direction opposite to the direction in which the main body of the tower shakes, so that it decreases the shake of the main body of the tower. Therefore, it protects the tower from earthquakes and the strong wind. The tower can withstand wind up to 60 m (200 ft) per second (134 mph (216 km/h)) and earthquakes up to 7 on the Japan Meteorological Agency seismic intensity scale.[1]
