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


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.


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.


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. 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[edit]

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. There is a wall painting “Aqua Fantasy” painted with special luminous paint called. After sunset, the painting is lit up by a black light, and the mysterious submarine view looks three-dimensional.

The third floor is the view coffee shop “Café La Plage” which is at a height of 109 m. There are 50 seats and visitors are able to eat and drink looking a fine scenery. Also, they are able to reserve it for a wedding or a party.

The fourth floor is the main observation floor which is at 113 m. It is the best view point 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 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 meters per second (134 miles per hour) and earthquakes up to 7 on the Japan Meteorological Agency seismic intensity scale.[1]
