Go Boards


Photo shows an 8-inch thick tenmasa kaya board. The scroll in the background features calligraphy by the Nobel Prize-winning writer Kawabata Yasunari. The characters read Shin'o Yugen, which mean `subtle and profound mysteries'. It is a term often used to refer to the fascination of go.		 Traditional boards with attached legs are usually made from the wood of kaya (torreya nucifera) or katsura (Japanese Judas tree). Boards made of kaya are superior in their color, brightness, and hardness. Aesthetically, kaya boards are considered ideally suited to the shell and slate stones. After being cut into blocks from trees over 700 years old, the boards are classified into two main types: itame (bent or irregular grain) and masame (grain running straight across the top of the board). Masame boards are further classified into tenmasa (grain running straight across the top) and tenchimasa (grain running from the bottom to the top as well as straight across the top). Besides these characteristics, the natural grain of the wood, defects in the wood, seasoning of the wood, and length of time elasped since the wood was cut into a board, are all taken into account in setting the price. Other valued attributes of kaya boards are that their color mellows with age and they produce a lively click when struck with a stone.

Kaya trees are found all over Japan. However, it is the trees found in Miyazaki prefecture, Japan, which are the most highly prized, in particular, the trees harvested from Mount Aya in Hyuga. Because of the warm Japan Current, which runs past Miyazaki, boards cut from these trees have a closer grain and a more pleasing color.

Katsura is the most widely used wood for boards in Japan (both for traditional boards with legs and for folding boards) because it is abundantly available and it is hard and durable. However, traditional katsura boards are always made with an itame grain and they lack the color and brightness of kaya boards.

Caution

Recently, both in Japan and in the West, boards said to be made from Chinese kaya trees are being sold at very low prices. However, these are not really kaya, but a related species of kaya. These boards have a strong tendency to crack and warp. The surfaces are also prone to chapping or flaking.

Another wood that is being used for go boards is spruce. It is marketed as shin-kaya, but it is a very inferior wood to be used for go boards. It is a soft wood and, after a short time, small dents will be made by stones striking the surface. The boards initially look very nice and the grain is almost always masame or tenchimasa, but the wood deteriorates rather quickly.

Go Stones

Go stones sold by Kiseido are manufactured in Japan with a standard diameter of 2.12 cms for the white stones and 2.18 cms for the black stones. The black stones are made slightly larger to compensate for the optical illusion that makes them appear smaller.

"Glass stones" are not made purely of glass. They are a composite of various ceramic materials that make them (under normal use) highly resistant to the chipping or breaking that one might experience when using cheaper stones.


Prices for Glass Go Stones
Code Description Thickness Price
S221 Glass Go Stones 6.0 mm $60
S222 Glass Go Stones 7.0 mm $65
S223 Glass Go Stones 8.0 mm $70
S224 Glass Go Stones 9.0 mm $75
S225 Glass Go Stones 10.0 mm $80




Shell and Slate Stones

Shell and slate stones manufactured in Japan are regarded by go players in Japan, China, and Korea as the finest stones available. Their weight, their color and grain, their pleasant feel, their responsiveness when placed on the board makes these stones the preferred choice for the games played in international tournaments.

The black stones in these sets are made from nachiguro slate mined in Wakayama prefecture, Japan. The white stones are made from a clam called hamaguri. These clams used to be harvested in Hyuga, Miyazaki prefecture, on the southern Japanese island of Kyushu and processed there into stones. Because of the Japan Current the grain of the stones made from these clams is aesthetically more pleasing. However, because of overfishing, clam shells from Hyuga are scarce, so today almost all shell stones made and sold in Japan are from shells harvested in Lower California, Mexico.

Shell and slate stones are manufactured in thicknesses ranging from 7 to 12mm. However, most players agree that a thickness of about 9.2mm is ideal. Many players feel that stones more than 10mm thick are too fat and it becomes awkward to place them on the board; this is a matter of personal preference.

Besides thickness, the white stones are classified into three grades: yuki, tsuki, and jitsuyo. Yuki stones have clear grains which run straight across the top. Tsuki stones have grain which curves across the top. Jitsuyo stones have either irregular or indistinct grain lines.

Yuki grade shell stones with the grain highlighted. The photo on the extreme right shows the approximate color of the stones.

Go Bowls

In Japan, you will find a large variety of go bowls made from different kinds of wood. Each has their own distinctive color and character. The most commonly used bowls are made of Chestnut; you will find them in many company offices where workers play go during their lunch breaks. Because of their durability, plastic bowls are often used in go clubs. (They won't crack if they accidently fall off the table).

Keyaki bowls are well regarded because of their durability and masame grain pattern. Their golden yellow color also matches the color of the highly prized kaya boards. The color of the cherrywood bowls are also well matched to the kaya boards. Rose keyaki are actually stained keyaki. They are made from keyaki wood whose original color and grain pattern is substandard. But these are sturdy attractive bowls that go well with the darker katstura boards.

The best bowls are made of mulberry, in particular, those that come from two neighboring islands, Miyake and Mikura, which are about 100 kilometers south of Tokyo. The bowls from Mikura are particularly highly regarded. They come in two basic colors: golden yellow and a reddish hue. The reddish ones are particularly beautiful. As you tilt them in the light, the color changes to a golden hue. Many of them have markings or prominent grain patterns which glisten when the bowls are turned in the light.

Unfortunately, a volcano erupted on Miyake island about five years ago that devastated the mulberry trees there and the ash that fell on Mikura island did a lot of damage to the trees there as well. Consequently, there are not many mulberry bowls left and the finest among them are quite expensive. (Click here to view some of these bowls.)

Choosing a Set of Board, Stones, and Bowls

In choosing a go set, the most important consideration is the balance in the quality of the board, stones, and bowls. If you own a fine tenmasa kaya board, it is aesthetically required that you have the finest set of yuki stones to go with it, preferably ones made from clams harvested in Hyuga. You would also want to store them in a pair of high-quality mulberry bowls. You would never want to use a set of yuki stones on a wooden folding board, nor would you use a set of glass stones on an expensive kaya board.

If you are using a traditional katsura board, there is no need to purchase an expensive set of yuki stones; a set of tsuki stones would best match the board. If you want to use the stones and board every day, but you want to play on fine equipment, a 2-inch katsura table board with jitsuyo stones (jitsuyo means `practical') would be adequate.

Chestnut bowls should be used with glass stones. If you decide to purchase a set of shell and slate stones to be used with a katsura table board or a katsura board with legs, then you should certainly move up to cherrywood bowls or keyaki bowls along with a set of jitsuyo or tsuki stones.

If you were to purchase an expensive kaya board, aesthetic balance demands that you match it with a set of yuki stones and bowls made from mulberry that grows on Miyake or Mikura island in Japan.

When you decide to purchase a go set, Kiseido would be happy to advise you as to what kind of set would best fill your needs. From the manufacturer's warehouse, we can select a wide range of equipment, from folding boards to traditional boards up 7.5 inches thick, glass stones, shell and slate stones up to 12 mm thick, and a variety of bowls to suit any taste.
