Hama Yumi
The is a sacred bow (''yumi'') used in 1103 A.D. in Japan. This bow is said to be one of the oldest and most sacred Japanese weapons; the first Emperor Jimmu is always depicted carrying a bow. According to legend; at that time, the Imperial Palace was taken over by an evil demon, which caused the Emperor to fall ill with great anxiety and suffering. When the Imperial High Priests tried and failed in their efforts to destroy the demon and dispel the Imperial household of its influence, they were at a loss. Finally, an archer, Minamoto no Yorimasa, was summoned to the Imperial Palace in the hopes of slaying the demon with his bow and arrow, ridding the palace of this plague. With a steady hand and a heart, Yo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bowstring
A bowstring joins the two ends of the bow stave and launches the arrow. Desirable properties include light weight, strength, resistance to abrasion, and resistance to water. Mass has most effect at the center of the string; of extra mass in the middle of the string slows the arrow about as much as at the ends. String forms Most bowstrings may be described as either simple, reverse-twisted, or looped. Simple strings may be made of any fiber, twisted into a single cord. Such strings have been used in many parts of the world and are still effective and fairly quick to make. However, they tend to be weaker for their weight, and they may also come apart if not kept constantly under tension. They are normally secured to the bow by a knot/round turn and two half-hitches at each end. Reverse-twisted strings are traditional in Europe and North America for most natural materials. Linen and hemp fiber have been widely used. The form is also used for modern materials. A reverse-twisted ...

Vermilion
Vermilion (sometimes vermillion) is a color family and pigment most often used between antiquity and the 19th century from the powdered mineral cinnabar (a form of mercury sulfide). It is synonymous with red orange, which often takes a modern form, but is 11% brighter (at full brightness). Etymology and common name Used first in English in the 13th century, the word ''vermilion'' came from the Old French word ''vermeillon'', which was derived from ''vermeil'', from the Latin ''vermiculus'' the diminutive of the Latin word ''vermis'' for worm. The name originated because it had a similar color to the Kermes (dye), natural red dye made from an insect, '' Kermes vermilio'', which was widely used in Europe. The first recorded use of "vermilion" as a color name in English was in 1289. The term cinnabar is used in mineralogy and crystallography for the red crystalline form of mercury sulfide HgS. Thus, the natural mineral pigment is called "cinnabar", and its synthetic form i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Yin And Yang
Originating in Chinese philosophy, yin and yang (, ), also yinyang or yin-yang, is the concept of opposite cosmic principles or forces that interact, interconnect, and perpetuate each other. Yin and yang can be thought of as complementary and at the same time opposing forces that interact to form a dynamic system in which the whole is greater than the assembled parts and the parts are as important for the cohesion of the whole. In Chinese cosmology, the universe creates itself out of a primary chaos of primordial qi or material energy, organized into the cycles of yin and yang, force and motion leading to form and matter. "Yin" is retractive, passive and contractive in nature, while "yang" is repelling, active and expansive in principle; this dichotomy in some form, is seen in all things in nature—patterns of change and difference. For example, biological, psychological and seasonal cycles, the historical evolution of landscapes over days, weeks, years to eons. The origin ...

Female
An organism's sex is female ( symbol: ♀) if it produces the ovum (egg cell), the type of gamete (sex cell) that fuses with the male gamete (sperm cell) during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes (unlike isogamy where they are the same size). The exact mechanism of female gamete evolution remains unknown. In species that have males and females, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Characteristics of organisms with a female sex vary between different species, having different female reproductive systems, with some species showing characteristics secondary to the reproductive system, as with mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender in the social sense of gen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Male
Male (Planet symbols, symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or Egg cell, ovum, in the process of fertilisation. A male organism cannot sexual reproduction, reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and Asexual reproduction, asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineage (evolution), lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamy, isogamous species with two or more mating types with gametes of identic ...

Ya (arrow)
is the Japanese word for arrow, and commonly refers to the arrows used in . ''Ya'' also refers to the arrows used by samurai during the feudal era of Japan. Unlike Western arrows, the ''ya'' is close to a metre long or longer. Traditional c:Ya, ''ya'' are made from natural materials, usually bamboo, while modern ones may use aluminium or carbon fiber. Parts of the ''ya'' ''No'' (shaft) The ''Commons:No (ya), no'' are made from ''Phyllostachys bambusoides, yadake'' bamboo and can have different shapes – straight or tapered – depending on the use of the arrow in long-distance shooting or target practice. Lighter arrows can lose their stability when shot from a strong bow, heavier arrows have a trajectory that arcs more. Typically they use bamboo from the Kantō region, Kanto area. This is for a purely practical reason: bamboo will not grow fast enough in a cold area and the joints are too close together, whereas in a warm area the bamboo grows too fast and the joints a ...

The Japan.html" ;"title="Toi gold mine museum, Japan">Toi gold mine museum, Japan. Gold leaf is gold that has been hammered into thin sheets (usually around 0.1 μm thick) by a process known as goldbeating, for use in gilding. Gold leaf is a type of metal leaf, but the term is rarely used when referring to gold leaf. The term ''metal leaf'' is normally used for thin sheets of metal of any color that do not contain any real gold. Gold leaf is available in a wide variety of karats and shades. The most commonly used gold is 22-karat yellow gold. Pure gold is 24 karat. Real, yellow gold leaf is approximately 91.7% pure (i.e. 22-karat) gold. Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years and is still done by hand.

Rattan
Rattan, also spelled ratan (from Malay language, Malay: ''rotan''), is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed-Canopy (biology), canopy Old-growth forest, old-growth tropical forests of Southeast Asia, though they can also be found in other parts of tropical Asia and Africa. Most rattan palms are ecologically considered lianas due to their climbing habits, unlike other palm species. A few species also have tree-like or shrub-like habits. Around 20% of rattan palm species are economically important and are traditionally used in Southeast Asia in producing wickerwork furniture, baskets, Walking stick, canes, woven mats, Rope, cordage, and other handicrafts. Rattan canes are one of the world's most valuable non-timber forest products. Some species of rattan also have edible scaly fruit and heart of palm. Despite increasing attempts in the last 30 y ...

Urushi
''Toxicodendron vernicifluum'' (formerly ''Rhus verniciflua''), also known by the common name Chinese lacquer tree, is an Asian tree species of genus '' Toxicodendron'' native to China and the Indian subcontinent, and cultivated in regions of China, Japan and Korea. Other common names include ''Japanese lacquer tree'', ''Japanese sumac'', and ''varnish tree''. The trees are cultivated and tapped for their toxic sap, which is used as a highly durable lacquer to make Chinese, Japanese, and Korean lacquerware. The trees grow up to 20 metres tall with large leaves, each containing from 7 to 19 leaflets (most often 11–13). The sap contains the allergenic compound urushiol, which gets its name from this species' Japanese name urushi (); "urushi" is also used in English as a collective term for all kinds of Asian lacquerware made from the sap of this and related Asian tree species, as opposed to European "lacquer" or Japanning made from other materials. Urushiol is also the oil ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Arrow
An arrow is a fin-stabilized projectile launched by a bow. A typical arrow usually consists of a long, stiff, straight shaft with a weighty (and usually sharp and pointed) arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and a slot at the rear end called a nock for engaging the bowstring. A container or bag carrying additional arrows for convenient reloading is called a quiver. The use of bows and arrows by humans predates recorded history and is common to most cultures. A craftsman who makes arrows is a fletcher, and one who makes arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Archery'' p. 56 History The oldest evidence of likely arrowheads, dating to years ago, were found in Sibudu Cave, current South Africa.Backwell L, d'Errico F, Wadley L.(2008).
