Many people may feel the pinch with the leaves and maple syrup drawn on the Canadian flag. It features a very hard, white-colored and glossy wood surface. In addition to furniture, it is also used for bowling lanes, musical instruments, exercise equipment, etc., which is resistant to impact. Characteristic heathers such as bird's eye heather and fiddleback heather are used as surface materials for musical instruments and siding boards of houses due to their beauty.
It is one of the world-famous woods that are prized along with mahogany and teak. When you think of walnut trees, I think you can feel familiar with them. Due to its heavy texture, it has been popular as a furniture material in Europe since the Renaissance. In the pioneering era of the west, it is believed that when iron is driven in, the color of the material becomes darker, and nails and bullets were driven in, so bullets may come out of the sawmill.

Cherry blossom

Origin: Russia Primorye / Japan Hokkaido whole │ Category: Beech family
Origin: Japan Hokkaido │ Classification: Rosaceae

The acorn tree oak has been revered as the "king of the forest" for its majestic tree shape and vitality. Since it is a slow-growing hardwood, it is most valuable as a furniture material that is over 150 years old. The unique striped pattern of tiger called "Torafu" is one of the characteristics of oak. It has excellent properties and has been used for a long time in architecture, furniture, ship materials, etc. In addition, the tannins and polyphenols contained in the materials dissolve in alcohol to give a rich fragrance, so they are also used in aging barrels for whiskey and wine. In addition to Russia, some Hokkaido oak is also used.
We use "Yamazakura" from Hokkaido. Since the material is tenacious and strong, easy to cut, and has little warpage, most woodblocks used for printing Ukiyo-e and books in the Edo period were Yamazakura. Although it grows to a diameter of about 1 m at the height of the chest when growing up, nowadays cherry tree can not take large materials, so there is a part where the redness and the white thick part that are characteristic of cherry blossom are clearly separated, and nature weaves You can enjoy beautiful colors. Changes relatively quickly, and the more it is used, the more it becomes glossy and turns reddish brown.
