Mitsuru (Man) Senda *1941, architect, Tokyo

Born in Yokohoma, Japan. Graduated from Faculty of Architecture of Tokyo Institute of Technology in 1964. Established Environment Design Institute, Tokyo in 1968. From 1982 on he was Professor, at Ryukyu University, later at Nayoya Institute of Technology and from 1992 on at Tokyo Institute of Technology.

A crucial element for Send's play environements is the vertigo (illinex) as Roger Callois described it: "The pursuit of vertigo ... consists of an attempt to destroy the stability of perception and inflict a kind of voluptuous panic upon an otherwise lucid mind."

Most of Senda's Play structures are based on circularity:

"An investigation of children's behavior revealed that on equipment which encourages games, play follows a circular route. Most playground games involve some form of chase and so include a natural end to the route. An investigation of primal landscape taught me that children stake out a playground they can run around but one with a shortcut, and further that this playground always has a open area where the children may gather. These structural elements of play form the thesis of my essay.

And, looking further into the circular route, the shortcut, and the necessary gathering spot on playgrounds, in architecture and at parks, I found that within this circular route the experience of some confusion is necessary. Also, a high space, place or thing is necessary as a symbol, and that overall the encircling route must be loose, offering several points of choice or diversion from the route, in other words, spatially full of holes."
(Zitat: Process: Architecture No 79, Environment design. Strategies of Man Senda+Environment Design Institute, p. 4.)

The Giant Play Structure was the first design concept in 1968. The idea behind it was that play structures must be in the nature of large trees. The first Giant Play structure was in Sendai (1968).
The linear Giant play structure are not very good for generating circulation play.
In 1982 Senda published a paper with a new type of play structure, the circular play system: Circulation, G Play Structure, Fortress of Winds, Möbius Band, Orbic, Running circle, Maze Place.

Community play structures structures are based on two concepts: the group play and the aesthetic value: "Play structures must be public art just like sculptures."

They are called Escargot, Ping Pong, Cosmos, Abacus Slider, Panel Tunnel, House of Winds, Sky Net, W Station, Bid Seesaw, Red House, Red Shoe, Möbius Ring, Tubie I and II, Super Log , Big Horn. They were designed for mass production, or in other words were created as industrial design, produced 1979 by Kotobuki, a Japanese furniture maker.
(Senda, 1992, pp. 20-75.

Circular Play Systems
- there must be an overall circulation of play
- children must be able to experience variation within the circle.
- the circle must contain a symbolic high point.
- the circle must contain a place where children can experience "dizziness".
- the circle must contain large and small gathering places.
- there must be shortcuts
- the circle must be accessible through a number of points so that it comprises a "porous" space.
