A ninja (忍者?) or shinobi(忍び?) was a covert agent or mercenary in feudal Japan who specialized in unorthodox warfare. The functions of the ninja included espionage, sabotage, infiltration, and assassination, and open combat in certain situations.[1] Their covert methods of waging war contrasted the ninja with the samurai, who observed strict rules about honor and combat.[2] The shinobi proper, a specially trained group of spies and mercenaries, appeared in the Sengoku or "warring states" period, in the 15th century,[3] but antecedents may have existed in the 14th century,[4] and possibly even in the 12th century (Heian or early Kamakura era).[5][6]

In the unrest of the Sengoku period (15th-17th centuries), mercenaries and spies for hire became active in the Iga Provinceand the adjacent area around the village of Kōga, and it is from their ninja clans that much of our knowledge of the ninja is drawn. Following the unification of Japan under the Tokugawa shogunate (17th century), the ninja faded into obscurity, being replaced by the Oniwabanshū body of secret agents.[7] A number of shinobi manuals, often centered around Chinese militaryphilosophy, were written in the 17th and 18th centuries, most notably the Bansenshukai (1676).[8]

By the time of the Meiji Restoration (1868), the tradition of the shinobi had become a topic of popular imagination and mystery in Japan. Ninja figured prominently in folklore and legend, and as a result it is often difficult to separate historical fact from myth. Some legendary abilities purported to be in the province of ninja training include invisibility, walking on water, and control over the natural elements. As a consequence, their perception in western popular culture in the 20th century was based more on such legend and folklore than on the historical spies of the Sengoku period.

There are quite a few products made in Japan, including TVs, and Microwave ovens... etc. Though, Sony, Hitachi, Sharp, Panasonic, Toshiba, etc. are some of the Japanese companies that manufacture products. Also, many different types of Pharmaceutical products and nice sports model cars are made there as well.

I have never lived there or been there myself, but since most of the technology is far more advanced than those in the states, I really want to visit. Hope this helps! :D

very generally, they represent good luck in japan. in china different numbers of fish, including koi, represent different kinds of luck i.e. 9 koi or 9 fish, means good financial luck.

In Japan, the symbolism of koi fish depends on their color.

• Yamabuki: The gold fish represents (of course) gold, wealth and prosperity.

• Ogon: The platinum colored fish represents the fulfillment of wealth in the form of success in business.

• Kumonryu: A midnight black colored fish that is named after a Japanese dragon of transformation - and this fish is said to bring about change in life circumstances.

• Kohoku: A white and red fish (known as a "cap" fish with white body and a red mark on its head) believed to encourage advancement in career.

• Kuchibeni: Also white and red (known as a "lipstick" fish with a white body and red markings around the mouth) said to inspire long lasting, loving relationships.

No. Samurai where made to kill. Killing is never good and very rarely seen as help.
