An yearly output of charcoal is about 1, 300, 000 tons in our country and Japan is the richest in charcoal in the world.
Japanese made charcoal is superior in quality and this superiority is due to the long period of histories and traditions in a method of charcoal making.
There are three kinds of charcoal making methods in Japan, Heaping method that is an ancient primitive charcoal making method in Japan, Oven carbonization which is believed come from China and modernistic charcoal making method. But the greater part of charcoal is made by oven heating method which produces white and black charcoal.Japanese charcoal is connected with a tea ceremony, Cha-no-yu and an ext-ernal appearance of charcoal is important in estimation of quality.
A charcoal was used for home fuel mostly but is increasing for business and industrial use now.
Japanese made charcoal is expensive and unfit for industry for the reason of the han-dicrafting method, and an expensiveness of raw wood meterials and labor shortage is affecting to the possibility of conventional charcoal making process gradually.Then mo-dernistic charcoal making method with much amount of waste in wood industry appeared.A charcoal has pualities of high chemical accesibility and high porosity, there fore an industrial application with these characters is much expected to come in future.

Wood distillation products are charcoal, pyroligneous liquor, wood tar, and wood gas.Wood turpentine and pine tar are obtained by the destructive distillation of such resinous woods as pine stumpwood.
Charcoal may be used into the domestic and specialized fuel and industrial fields just like the one from kiln-burning methods.
Pyroligneous liquor has miscellaneous uses as a disinfectant, weed killer, deodorizer, antioxidant, and as raw materials for making preservative, insecticide, and crude iron acetate: Distilled pyroligneous acid has many uses as a coagulating medium for rubber latex on rubber plantations, besides the uses in pyroligneous liquor.Distilled pyroligneous acid is refined by redistillation and special treatments.Refined pyroli-gneous acid can be used as a smoked flavouring for fish and meat, as a deodorizer and a preservative in the cooking for fish, meat, and other foods.
The phenolic fraction of wood tar is the raw material for medicinal creosote oil.Pine tar is used chiefly for softening agent of reclaimed rubber in making truck tires.
Wood turpentine contains small amounts of medicinal creosote oil.Refined wood turpentine is used chiefly as a volatile thinner and solvent for leacquers, as ingredients for insecticides, and as a raw material for making softening agent of reclaimed rubber.Wood gas is used only as a fuel in the plants where it is produced.

Among of the industrial products using charcoal as main reducing agent, is there silicon metal.This paper describes its properties, process of produ-ction, specification, and utilization together with what is required for charcoal in the process of silicon metal production.In Japan, researches on the refining of silicon metal have been carried out in recent years so as to obtain the good quality of charcoal needed for the production of silicon metal.In this paper, the author pointed out that the charcoal for silicon metal should be low and uniform in calcium content.Actual calcium content of charcoal is very different between duramen and cortex, and between kinds of wood and producing ficld.The author emphasized that from the view point of producing silicon metal establishment of standards for charcoal and improvement of charcoal producing method should be made in the near future.

In Japan, 4-5 sets of blast furnaces, using charcoal as fuel and reduc-ing agent, produces about 40, 000 t of special pig iron, that is charcoal pig iron, which needs about 24, 000t of charcoal aunually.A great amount of charcoal used for special pig iron is the domestic one, which needs no special properties.However, the anthor describes its desirable properties for the charcoal blast furnaec together with its behavi-our in the blast furnace.

Carbon disulfide is mainly used for the productions of rayon, staple fiber and cellophane, and the total production of carbon disulfide in 1961 amounted to about 120, 000t, for which about 26, 000t of charcoal was consumed.At prent, cha-rcoal is the most excellent as the carbon source for carbon disulfide production.Its optimum properties are as followings: kinds of charcoal: white, charcoal, kinds of wood: oak, Japanese oak, etc., volatile Matter: under 5%, ash content: under 3%, moisture: under 10%, and hardness: 5-10°.
