What are simple ?
They are completely different between "No parts are wasted." and "With nothing.".
Simple avoiding any inefficient parts is very difficult.
It would result in ultimate with tireless pursuant, and it would be one of the best approach.
"Beauty of Shaving off" would be unique to Japan, thus, it might be inherited from ancestors through DNA, however, it is still difficult.
It would be true to take care of tractability in manufacturing, which would directly impacts costs and stable supply, when considering consumers in our mind, however, we frequently observe crafts called simple which are made solely from the point of manufacturers. I would call them as "Simple with nothing."
The difference between "no parts are wasted" and "with noting" would come from starting point of mindset and object of enthusiasm, i.e, whether consumers or manufacturers.
So, I always pursue genuine simple thinking about those who use furnitures.
What are required for chairs from the point of comfortableness, functions. They would be comfortableness under longer usage, longer term endurance, easy to move.
Considering all above, I pursue to shave 1mm and/or 1g off.
I continue to try manufacturing furniture with minimum volume and the smallest number of parts with meaningful shapes and structures.
And, in order to reduce costs, highly productive structures and processing together with the best fit number of production lots.
I always try to make furnitures seeking these kinds of aspects, however, it is difficult to achieve.
This time, I choose cedar.
Cedars are soft, thus, not suitable for wood for furnitures, however, light and warm.
It has unique aroma which calms down tense.
It is also unique tree in Japan.
However, it is not suitable as materials of chairs at all given its softness.
And it requires unique structures.
It is also difficult to scrape with planes and/or swords.
The difference between cedars and other wood materials would be something like between drawing paper and tissue paper.
I thought through of the shape of parts to be strong enough with half-pipe, R-shape, rib-shape without thickness.
It is achieved through technique fully utilizing plans and swords.
It weigh slightly above 4kg.
It is about half compared to one made of walnut.
It would be very light in this kind of personal chair.
It would be about perfect in terms of strength and comfortableness in sitting.
However, it would not still enough.
Further better would be possible.
While I would have kind of sense what are missing, I cannot make it due to inadequate technique and experiences.
I have another thought relevant to making chairs from cedar.
Many talk about utilizing thinned wood, which seem to be nonsense.
Thinned woods tend to be just scrap woods in order for main wood to grow.
Some manufactures tend to use the word as sales pitch.
Given 100 years of great cares through multiple generations, final cutting woods have value.
So, it can be made of final cutting woods which would not have cracks and knots with larger portion of red-colored core materials. It cannot be made of less strong thinned woods with almost entirely occupied with white-colored peripheral material.
I have been seeking for true nature, which is not easy.
It always changes.
I have gained more insight through experiences.
Then, I have noticed new essences.
So, occasionally what had been beloved may be completely changed.
Actually, I do not care about every changing nature of essences because the further stepping forward, the closer to true nature.
I need to understand that today's best may be tomorrow's rubbish.
It would be flexibility and element of growth.
I would like to be open to something new as if I re-born everyday.
It would be the most important in manufacturing and running companies.
Anyway, I would like to make valuable works which make people happy.
I continue to think highly of taking care of others without ingratitude.
Other people make me feel so.
I have been always inspired by surrounded people with seeking true nature.
So, surrounded people themselves are value of me.
