We moved this website on a faster server for your convenience. Anyway, due to this reason this homepage and email experienced some down time in the period 1/28 ~ 2/5.
We sincerely apologise for the unconvenience. If you contacted us by mail or by our request form, chances are that we did not receive your kind request.
These are some pictures kindly participated by a client and friend who owns a large knotty hinoki tub. He refurbished a country house in central Italy and is the lucky owner of this unique bath house…
how can I properly comment these pictures?
I come up with this haiku (short japanese poem):
samui fuyu ni / kokoro atatameru / kimi no aijo
in the cold winter / warming up my heart / your friendship
In these pictures it is easy to understand how the side walls of a hinoki tub are laminated.
First the material is assorted so that knots or other imperfections get discarded and of course, so that the total width of the planks is equal on the four sides of the tub. This is also a way to optimize the use of the material and avoid loss.
The wood is hand sawn by overlapping 2 planks so that with one single cut two perfecly matching planks are cut.
The pictures show the phase when the planks are drilled and connected with woodes plugs (dabo). The planks are joined with a waterproof bond and kept in the press overnight.
The corner of the tubs are realized with a more complex joint which is sealed by the insertion of hinoki wood bark which acts as a kind of natural gasket. Moreover, this bark has excellent fungicidal property and prevents mold stains in the most vulnerable point (the corners).
What am I doing here!?
Actually, today we showed our material and products to a perspective customer from Germany who is visiting Japan.
It is always a pleasure to have a tea together and exchange thoughts with fellow westerners who share with us passion for japan and fine hand crafts.
We looked at the plans and after some talking, we felt it might be easier just to try one tub, as you would do with a pair of boots. We had an “outlet” tub and the client could enter and get a more direct idea of the size and of the feeling of the tub.
Even a smaller tub seems spacious and comfortable when you try it. No big surprise, the sizes we were recommending actually did fit perfect, anyway after trying the tub the client could feel reassured and move forward without worry.
If you visit Japan, drop by for a tub fitting (if you let us the time we can pick you up at JR Maihama station).
Well, we wanted to show you how it works so I found the good excuse to enter the tub myself…
These large round tubs were made for a hot spring luxury hotel near Mt. Fuji.
They are so beautiful to look at that I could stay here staring for hours…
Can you imagine how would it be to take a hot bath inside?
Just for your information, round tubs of this size go for 16,000 + per piece, without transportation cost…
On the other end, how much is our physical and mental health worth?
We do not have statistical data but it is known that a relaxing bath a day improves almost all body functions and extend life-span. Additionally it is also believed to improve relations and productivity.
This may be the reasons that made a client comment “In this time of financial uncertainty, a japanese tub is actually the best investment I made. Under all points of view.”
Here is how we are building the 100% natural tub in the traditional way.
The shape most suitable is the “TARU” which is assembled like a barrell with vertical planks of hinoki. The water pressure distributes uniformly on the perimeter and is collected by the stainless steel bands hammered from the bottom up.
The hinoki planks are cut with variable angles so to match eachother seamlessly. Between these we used a natural bond made of rice starch called “SOKOI”. This is 100% natural and does not contain anything but rice and water!
