I designed 8 meter height Bamboo Fibonacci Tower for the TANABATA Festival in Shizuoka Japan.
The TANABATA is an Asian Celestial Festival like Christmas in western culture.
The silhouette of the tower is catenary curve, that is, Antoni Gaudi used it frequently.

The volunteer girls sawed off the thick bamboo poles.

In parallel, volunteers made bamboo stakes.
We must prepare 300 stakes at least.

It took for two days to cut the bamboo poles then I curried them by my small truck.

We brought the bamboo poles in the museum's garage.
The garage was full of bamboo!

I marked the points for drilling precisely.
The error must be within 1mm.

I drilled pilot holes.
It must be as vertical as possible.

In parallel, I prepared such wooden members for wall using 2*12 lumbers.

3rd of June.
Usually I don't like high altitude.
But I have to be the highest altitude because of my own responsibility.

I hung very heavy metal bell from top of the tower.
It makes the tower very stable against earthquake.
It is a seismically isolated structure like the five-story pagoda that Japanese ancient carpenter invented more than 1000 years ago.
