hinoki heaven in california

This order was coordinated by the owners` architects.
We discussed several options, sizes and details.
In a couple of occasions the owner asked some more time to consider the details but the project went on smoothly.
The architect was also very cooperative in taking care of the ISF filing.
Recently, a new regulation has been implemented for ocean freight imports. The importer (the client) has to fill a Importer Security Filing and submit it before the merchandise is boarded in Tokyo port.

The procedure is quite simple but of course it is a headache for every first-timer. Our forwarder`s clumsy english complicated things in the beginning but the client always positive attitude allowed us to literally jump over all the obstacles!

As you can see our tub this time is a minimalist box, L1500mm x W800mm x H640mm (ext. dim.) 530mm(deep) with a L-shape corner (no top frame) This detail required 47mm thick planks @ walls. The material of course is japanese Knotless (quartersawn) Hinoki wood.
and the tub has a copper apron, and wooden dowels details for the corner joint.

We also shipped accessories such as our 100ml Asnaro-Hiba Oil, a Sawara wood large bucket(230D 120H)and Asnaro wood stool (330x220x300H)

This time the local carpenter is going to build a duckboard on site so we send matching material.
The floor planks are readied with anti-warping slits on the back and a full penetration hydro repellent treatment. Planks are knotless L2000mm x W100mm x t15mm while the sleepers are in B grade, L2000mm x 45mm x45mm

If I close my eyes, I can already see the tub surrounded by the floor grating and filled with steamy water!

hinokitiol powder

Hinokitiol is used as a component for soaps, scalp treatments, skin acne treatments.
Chemically, it is tropolone and is extracted from hiba oil with a laborious ultrasonication process which takes about 6 months.

Hiba oil has a yield of about 2% (it takes 50 Kg of wood to obtain 100g of oil)
Hinokitiol content inside the oil is about 1% so it takes 5000Kg of wood to obtain 100g of pure crystallized hinokitiol)
We sell hinokitiol powder in 1g bottles:

hinokitiol-w

In the picture below is 1g of hinokitiol powder.

Hinokitiol has a natural bactericidal action and can prevent skin scaling, dandruff, acne or atopic dermatitis (eczema).
It can be used as a treatment for skin diseases.

(Asnaro)-Hiba tree has a high concentration of hinokitiol (also known as Thujopsene) which has very powerful antiseptic properties. J. Antimicrob. Chemother.-2003-Arima-113-22.pdf

Hiba oil has a very strong forest scent, reminescent of cedarwood, maybe too intense for many people, especially ladies.
Also, even though allergic reactions are very rare, concentrate application of hiba oil directly on skin may cause a temporary rush and itching.

On the other hand, the hiba oil has a natural content of hinokitiol (about 2%) which makes it an asset when used against skin infections or for food preservation.

For this reason, we extracted pure hinokitiol (powder) and add it to hinoki oil which has a more gentle and widely appreciated aroma.

Personality of the hiba cypress

It is called Hiba cypress or “arborvitae”, and refuses to co-exist with other trees.
Hiba is a tree native of Japan, additionally we can say that about 80% of the hiba trees are located in Japan, in the Aomori prefecture. Forests have an average age of 200-250 years, it is a tree that grows over the years slowly tempered by the harsh wind and snow of the northern japanese region. Together with hinoki and sugi pine, hiba is one of the three large trees of Japan and as a building material it is considered “first class” for its resistance to rot.

(above is a photo of 1000 year old hiba wood from the Sarugamori forest on the northern tip of aomori prefecture.)

Hiba is used in construction and together with hinoki it has the honor of being preferred for the construction of shinto shrines.
Hiba hard to rot quality is surprising compared to other trees: we can often find in the mountains leftovers of wood logged 100 years ago and the heatwood is in perfect conditions, it even maintains its fresh fragrance! Hiba is used in history many buildings Including Hirosaki Castle, this is also proves its resistance to rot in the humid japanese weather.

The reason of its resilience is its high content of hinokitiol (also known as Thujopsene).
This natural chemical compound in the family of terpenes and was first isolated in Taiwan hinoki: this is the reason for the name.
Actually, it is contained in very small amount in Taiwan hinoki, and even less in Japanese hinoki.
The plants that contain high value of hinokitiol (about 2% of the weight of the heartwood) are the Japanese Hiba cedar (Thujopsis dolabrata) and the Canary Islands Juniper (Juniperus cedrus)

wedge shaped tub for singapore

We received an information request for this tub on the last day of the year.
The construction work on the apartment was still in progress so the manufacture was scheduled for may. It ends up that the work is ahead of schedule so the production should be anticipated. Luckily, for a shipment to Singapore of a small sized tub, airplane is cheaper than sea-freight so we could cope smoothly with the change of schedule.

The tub is compact and has a slanted side (the flat side will be positioned against the wall)

outdoor tub for the west coast

This project went thru a very smooth process. It took about 2 weeks for deciding the options, 2 weeks for construction and 4 weeks for shipping and delivery.
The client went thru our website carefully and indicated a custom tub close to her image.
The tub is to be used outside so we recommended a thermal cover (to be purchased locally).
During the winter the cold temperature results in a lower relative humidity.
If the tub is winterized we would recommend to wrap the tub with a cellophane sheet before covering it, to prevent the humidity loss.

The tub is in asnaro wood.
Sizes are L1400mm x W900mm x H680mm (ext. dim.) 600mm(deep)
