# Chiba Port Tower

Chiba Port Tower is a tower located in Chiba Port Park, Chūō-ku, Chiba, Chiba Prefecture, Japan. It is 125.1 m (410 ft) tall and has four stories. It was built in 1986.

## 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 width 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.

## Floor guide

The tower has four stories. First, visitors go up to the fourth floor from the first floor by using the elevator. Then, they go down to the third floor and the second floor. Finally, visitors go down to the first floor from the second floor by using the elevator.
The first floor is the entrance. There is a shop that sells goods related to Chiba and an exhibition room that explains the role of Chiba Port. Also, there is a theater and a kid's room.
The second floor is the view room which is at a height of 105 m (344 ft). There is a wall mural painted with special luminous paint called “Aqua Fantasy”. After sunset, the painting is lit up by a black-light, and the mysterious underwater view looks three-dimensional.
The third floor is the view coffee shop “Café La Plage” which is at a height of 109 m (358 ft). There are 50 seats and visitors are able to eat and drink while enjoying the view. It may be rented for private events such as wedding and parties.
The fourth floor is the main observation floor which is at 113 m (371 ft). It is the best viewpoint of the tower. There is an open space between the first floor and the second floor. Therefore, visitors are able to see the scenery of the sea while taking the elevator.
At the top of the tower there is a system called dynamic damper. It weighs about 15 tons and moves in the opposite direction from that which the main body of the tower moves, so that it cancels-out the oscillations of the tower, protecting it in earthquakes and 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.
