Social Structure of Ancient Japan!

Bush Tucker Story- Mick Namari Tjapaltjarri

Aboriginal art is a highly distinctive environmental art form associated with the spiritual beliefs of the native people of Australia. Traditionally, Aboriginal art includes rock paintings, dot paintings and bark paintings. Often, aboriginal designs illustrate the “Dreamings” that underpin Aboriginal spiritual and cultural life. Visual Art is only one of the ways of expressing Aboriginal dreaming. It can be expressed by dance, music, story and craft. Aboriginal art comes out of their culture and beliefs. In the artwork (Bush Tucker Story) by Mick Namari Tjapaltjarri, there are a variety of lines and dots that join together to create the swirling design. The semi-circle like figure represents rainbows, clouds and cliffs. On the far right hand side of the artwork there are lines that represent fire, smoke, water and blood. It represents the power of water for the growth of plants, running water over the ground and the sight of rainbows after the rain.

Minamoto no Yoritomo- The first shogun of Japan!


Minamoto no Yoritomowas the founder and the first shogun of the Kamakura period. He created amilitary system that lasted over 700 years, made a lasting impact on the modernday police force and made the Buddhism religion one of the most popularreligions in Japan.

Minamoto no Yoritomowas the founder and first shogun of the Kamakura period. In 1192, Yoritomoconfined the emperor, this lead to Yoritomo being granted the title of shogun.He therefore had supreme authority over the military force in Japan. Yoritomoestablished new governors throughout Japan. Yoritomo was able to rule withoutoverthrowing the emperor. Even now in modern Japan, the emperor has no realpower. 

Minamoto Yoritomo wasalso well known for creating a military system that lasted over 700 years! Thismilitary system Yoritomo created, operated independently of the court. Thistherefore led to Yoritomo controlling the entire military without anypermission from anyone else.  Yoritomoappointed military governors over different provinces. The governors receivedland in return for their work. Yoritomo also appointed stewards to look aftermanors. The stewards received a certain amount of money in return for theirmilitary service.

Another thing Yoritomodid for Japan was making Zen Buddhism a big religion. He did this in thought ofJapan being a calmer and more peaceful place to be. When Yoritomo was young; hespent a lot of his time in a Buddhist temple. Research tells us that Yoritomothought that life should be lived through discipline; he apparently thoughtthis was the only thing that could bring joy. Yoritomo also created Zen Templesand Zen Schools for people to both meditate and learn about Buddhism and why itis important.

Yoritomo’s samuraisystem has had a lasting impact on a modern day police force. The two of them:Samurai and the Police Officer. Took orders, had power and weapons, seek gloryin battle, violent and fight for some sort of payment. The samurai and thepolice officer look similar to each other as well. They wear armour or somesort protective clothing. This was another one of the many legacies Yoritomoleft behind.

Though some say thatYoritomo was savage and ghastly, the legacy he has left behind has beenrevolutionary! He was the founder and the first shogun in the Kamakura period;he has reformed the military system that lasted over 700 years, made a lastingimpact on the police force and took Zen Buddhism to an entirely new level.

Cells!

Cells are the basic units of all living things. The first cell appeared on Earth about 3.5 billion years ago. Today, there are many different kinds of cells. The differences in the cells of organisms are sometimes used to classify them into groups. Although cells may vary in their size, shape, contents and organisation, they all perform functions that are involved in keeping the organism to which they belong alive.A whole new world was discovered just over 400 years ago when an English inventor and scientist used magnifying lenses to observe the basic units of which all living things are made. This led to a new way of thinking about living things that required a new scientific language, new classifications and new inventions to find out more about this new world.In the seventeenth century, Robert Hooke looked at thin slices of cork under a microscope (= very small + view) that he had made himself from lenses. He observed small box-like shapes inside the cork. He called the little boxes that he saw cells. Microscopes opened up a whole new world that had never been seen before.Using microscopes to carefully observe different living things showed that they also were made of these tiny basic units. As the magnification provided by microscopes increased, it could be seen that, although the basic structure of cells was similar, there were quite a few differences. Different groups of organisms often contained different types of cells. It was also discovered that different types of cells could be found within an individual organism.

Emperors and Shoguns

The earliest written histories of Japan date to the early eighth century and are a mixture of fact, myth and legend. In these histories, the emperor is said to be descended from the sun goddess. A grandson of the goddess, Ninigi, settled in northern Kyushu and held three sacred objects:
  • a mirror, a symbol of the sun
  • a sword, discovered in the belly of an eight-headed serpent
  • a jewel.
These objects became symbols of the monarchy.
In AD 794, the emperor Kammu moved the capital from Nara to Heian (modern-day Kyoto), which was to remain the capital for over 1000 years. The emperors and their court lived in a luxury not seen in western European courts until the eighteenth century. The splendours of this life were described in the world's earliest novel, The Tale of Genji, written in about 1004 by a lady of the court named Murasaki Shikibu (AD 978 to c.1016).
To maintain his rule, the emperor needed support from nobles who were sent out to manage the provinces. The nobles were allowed to keep their own armed guards for protection, and these men came to be known as bushi(warriors) or samurai (retainers). Over time the nobles became rich from crops grown on their private estates and taxes they collected and loyalty developed between the nobleman and his samurai.
During the twelfth century, there were struggles between members of the imperial family, and nobles in the provinces took the opportunity to try to seize power. The second half of the twelfth century was marked by fighting throughout Japan, as well as natural disasters such as floods, typhoons and earthquakes. The final victor in 1185 was Minamoto no Yoritomo (1147–1199).
After his victory, Yoritomo made a decision that was to influence Japan's history to the present day. Instead of making himself emperor, he asked the imperial court to recognise his power with the title seii tai-shogun (barbarian-subduing-great-general), but at the same time the emperor was to keep his symbolic position.
Both gained by this. The shogun was given legitimacy in his position rather than being recognised only for his military power, while the emperor was allowed to retain some of his prestige and given a degree of protection. It also meant that there was a line of divine authority from the emperor through the shogun to the nobles beneath him.
During the twelfth and thirteenth centuries, much of Europe and Asia was dominated by the Mongols. The Mongol emperor Kublai Khan (1215–1294) was the grandson of the great Genghis Khan and ruled Korea and northern China. From here, he turned his attention to Japan.
Kublai Khan launched his first raid from Korea in 1274, attacking the coast of the southern island of Kyushu, which was the area closest to Korea. However, this attack failed.
In 1281, Kublai Khan sent a much larger force of about 140 000 men and thousands of ships, this time from both Korea and China. The Japanese had spent the time preparing for a new attack by:
  • building a stone wall around Hakata Bay
  • amassing a large number of troops
  • training these troops in the technique of group fighting used by the Mongols (traditional Japanese fighting was a one-on-one encounter).
The battle lasted for seven weeks but was brought to an end by a great storm. About half of the invaders perished. The Japanese believed this typhoon was sent by the gods and they named it kamikaze, which meant ‘divine wind’. The same name was used in World War II to describe the Japanese pilots who deliberately flew their bomb-laden planes into enemy ships.
The defeat of the Mongol invasion did not bring peace to Japan. There was a brief period when the emperor managed to reassert his power over the shogun, but during the fifteenth and sixteenth centuries, Japan was plunged into a long period of civil war. This was also a period in which Europeans attempted to gain access to Japan: the Portuguese were first, followed by the Dutch. The muskets (guns) of the Europeans, which were more advanced than those of the Mongols, particularly impressed some of the warriors. In 1527, the warlord Odo Nobungaga won a battle in which he used 300 musketeers.
Final victory in the civil wars went to another warlord, Tokugawa Ieyasu (1542–1616). In 1603, Ieyasu revived the title of shogun, receiving the title from the emperor. The role of shogun was to remain with the Tokugawa family until 1868, giving the period its name — the Tokugawa Shogunate.
Ieyasu soon took steps to strengthen his position. The system he developed had some similarities with the feudalsystem in medieval Europe. First, Ieyasu made it clear to the emperor that the position of emperor was only a symbolic one and as shogun he had the right to approve all court appointments.
The shogun controlled about 25 per cent of the land, while the remaining 75 per cent was divided up into domainsruled by about 275 daimyo (lords). A rich daimyo with his samurai could be a threat to the ruling shogun, so Ieyasu placed many restrictions on the daimyo. For example:
  • they could not marry without the shogun's approval
  • they could not build new castles, and the shogun had to approve any repairs to existing castles
  • there was a limit to the number of samurai they could have
  • most bridges were destroyed, allowing travel only along certain pathways so that the movements of daimyo could be controlled.
