【Social Studies】Building a Nation Centered on the Emperor: The Era When Japan’s Foundation Was Laid
Hello everyone! From today, let's learn about a new chapter in history: "Building a Nation Centered on the Emperor."
You might think, "History has so much to memorize, it seems tough..." But don't worry! This era is like the "startup phase of Japan," a thrilling time when the rules and systems that form the foundation of the Japan we live in today were established. Let's enjoy the story of how historical heroes like Prince Shotoku and Prince Naka-no-Oe dreamed of a future and took action to lead the country!
1. Prince Shotoku’s "New Nation Building"
About 1,400 years ago during the Asuka period, Prince Shotoku (Prince Umayado) became the regent (an assistant to the Emperor) for Empress Suiko. He sought to transform the country from a land governed separately by powerful clans (Gozoku) into a unified nation centered on the Emperor.
① The Twelve Level Cap and Rank System
Until then, your future rank was decided solely by the family you were born into. However, Prince Shotoku created a new system where "people are appointed to government positions based on talent and merit, regardless of family background." This is the Twelve Level Cap and Rank System.
[Analogy] Imagine if a company had a rule that said, "You're the next CEO because you're the boss's son," and it was changed to, "Anyone who is good at their job can become a manager!" That makes you want to work harder, right?
② The Seventeen-Article Constitution
These were the rules that outlined the mindset government officials should hold. The most famous is Article 1: "Harmony is to be valued." It means that everyone should discuss things and work together in peace.
Key Point: Remember that this was not a set of laws for all citizens, but strictly a "code of conduct for government officials."
③ Sending Envoys to the Sui Dynasty
At the time, our neighbor China (the Sui Dynasty) was a very advanced nation. Prince Shotoku sent Ono no Imoko and others there to study China’s advanced culture and political systems.
Fun Fact: In a letter sent to the Chinese Emperor, it was written, "The Son of Heaven where the sun rises sends this to the Son of Heaven where the sun sets..." This is said to be Prince Shotoku’s strong message that "Japan and China are on equal footing."
[Summary of this section]
Prince Shotoku tried to build a strong nation centered on the Emperor using three pillars: "Meritocracy," "Rules for Officials," and "Knowledge from Abroad."
2. The Taika Reform: A Challenge for Big Change
After Prince Shotoku’s passing, a clan called the Soga clan once again gained immense power and began governing selfishly. Standing up against them were Prince Naka-no-Oe and Nakatomi no Kamatari.
From Coup to New Politics
In 645, they defeated Soga no Iruka. The political reforms that began as a result are called the Taika Reform.
This was the first time an era name (nengo), "Taika," was used. The root of the "Reiwa" era we use today lies right here!
The System of Public Land and Citizens
A major goal of the Taika Reform was to take land and people away from the control of powerful clans and make them "belong to the Emperor (the state)." This is called Kochi Komin.
[Study Tip] You can remember the year 645 as "Let's steam some rice (6-4-5) for the Taika Reform!"
[Summary of this section]
Prince Naka-no-Oe and his allies defeated the over-powerful clans and brought land and people under state control, cementing a system centered on the Emperor.
3. Heijo-kyo and the Nara Capital: A Splendid Era
In 710, a large-scale capital city called Heijo-kyo was built in what is now Nara Prefecture. This marks the beginning of the Nara Period.
City Planning Like a Go Board
Heijo-kyo was modeled after Chang'an, the capital of the Tang Dynasty (present-day China). It was laid out like a "Go board," with roads running straight and orderly in a grid pattern.
[Common Mistake] Remember the year 710 as "A truly (710) splendid Heijo-kyo." Be careful not to mix it up with Heian-kyo (794)!
The Wish Behind the Great Buddha
During the Nara Period, the country went through tough times with epidemics (smallpox) and political infighting. To stabilize the country through the power of Buddhism, Emperor Shomu ordered the construction of the Great Buddha at Todai-ji Temple.
Key Point: Emperor Shomu called for "everyone in the nation to cooperate in building it." A monk named Gyoki contributed by helping the people, building bridges, and assisting those in need.
Treasures of the Shosoin
The Shosoin Repository at Todai-ji still safely stores items associated with Emperor Shomu and treasures from as far as West Asia and Persia that arrived via the Silk Road, showing how internationally connected Japan was.
[Summary of this section]
The Nara Period was an era where a magnificent capital called Heijo-kyo was built and a very international culture flourished, with the government aiming to protect the nation through the power of Buddhism.
Finally: Important Test Points!
It might feel difficult at first, but if you think of the flow of this era as "the process of turning a scattered Japan into one team (nation) centered on the Emperor," it’s actually quite simple!
