Material: 510 green bamboo 3m long
Size: 3mx3mx3m

More than 600 green bamboos, freshly cut from the neighbouring bamboo forest, were prepared.
All the bamboos were cut to a length of 3 m.

The basic structure of the MUMAGARI was discovered in 1992 (PatentNo. 3493499).
As a giant quasi-crystal sculpture of bamboo, it has been made in Chichibu, Innsbruck, Zurich, Atlanta, Tokyo, Sao Paulo and elsewhere. This time, the challenge was to use freshly cut green bamboo. Natural bamboo is usually curved and uneven. Freshly felled bamboo is also heavy and soft.
In general, it is a tricky material to use in structures.
Taking advantage of this irregularity, I decided to try to construct the MUMAGARI in a hyperbolic spatial way.

When I actually started to assemble the bamboo, the work was more difficult than I had imagined, although I felt that I had a good handle on it.

Almost completed.
In the end, it took 10 days to complete.
The total weight exceeded 500 kg.

View from the upper floor.

On the last day, with the help of 10 people, it was moved into position.

The work is located in the TAKE LABO, Ethical Bamboo's laboratory.
It will be displayed by its entrance.

View from the five-fold symmetry axis.
The work was hard, but the hyperbolic spatial composition united them more firmly than in previous works, and the symmetry of the dodecahedron appeared of its own accord with the bamboo's own elasticity.
