【History】Early Modern Japan: From Unification to the Edo Shogunate

Hello everyone! Let's dive into the period known as the "Early Modern" era. You might feel like history is just a mountain of things to memorize, but don't worry! This era is actually a super dramatic and exciting time when the foundations for modern Japan's rules and culture were first built. Let's have some fun tracing how famous heroes like Oda Nobunaga and Tokugawa Ieyasu united Japan and paved the way for a peaceful era!

1. The Road to Unification: Nobunaga and Hideyoshi

At the end of the Warring States period, two key figures emerged to pull a fragmented Japan together: Oda Nobunaga and Toyotomi Hideyoshi.

(1) Oda Nobunaga’s Innovative Strategies

Nobunaga expanded his power using groundbreaking ideas that broke away from tradition.
・Battle of Nagashino: He used the then-cutting-edge "matchlock gun" in a tactical, organized way to defeat the Takeda cavalry, which was considered the strongest at the time. ・Rakuichi Rakuza (Free Markets): He abolished trade monopolies, allowing anyone to do business freely. This was all about keeping the cities buzzing with activity.
【Key Point】 Remember Nobunaga as the person who "broke old rules to create new systems!"

(2) Nationwide Unification by Toyotomi Hideyoshi

Hideyoshi succeeded Nobunaga and finally united Japan. Two of his "Major Surveys" are exam classics:
・Taikō Kenchi (Cadastral Surveys): He surveyed the size and crop yield of fields across the country, creating a system to reliably collect annual tax (nengu). ・Sword Hunt (Katanagari): He confiscated weapons from farmers. This made the distinction between "samurai" and "farmers" very clear (separation of warrior and farmer classes).
【Did you know?】 Hideyoshi is the only person to rise from a lowly foot soldier (ashigaru) to the very top. Perhaps that’s why he understood better than anyone how dangerous it was for farmers to revolt.

【Summary】 Nobunaga built the foundation, and Hideyoshi cemented national unity through "land rules (surveys)" and "class rules (sword hunts)."

2. The Establishment of the Edo Shogunate

After Hideyoshi passed away, Tokugawa Ieyasu won the Battle of Sekigahara in 1600 and established the Edo Shogunate in 1603. This kicked off the Edo period, a time of peace that would last for about 260 years.

(1) Controlling the Daimyo

To prevent the daimyo (regional lords) from rebelling, the Shogunate created strict rules.
・Buke Shohatto (Laws for Military Houses): Laws that daimyo had to follow. It included strict rules like "don't repair your castle without permission" or "don't get married without approval." ・Sankin-kōtai (Alternate Attendance): A system requiring daimyo to travel back and forth between Edo and their own domains every other year.
【Analogy】 Think of Sankin-kōtai like being "forced to take an incredibly expensive, family-wide moving trip every year." By making them spend so much money, they didn't have the spare cash to buy weapons for an uprising.

(2) Social Structure

The Edo period had a rigid class structure. The Samurai were the ruling class, followed by Hyakusho (farmers) and Chonin (artisans and merchants).
*Modern textbooks don't use the term "shi-no-ko-sho" as much, but the important thing is that the distinction between samurai and everyone else (farmers and townspeople) was strictly enforced.

【Common Mistake】 "Hyakusho" doesn't just mean farmers. It also includes fishermen, woodcutters, and more. Back then, they made up over 80% of the population!

3. Relations with Foreign Countries and "Sakoku"

The Shogunate feared that Christianity would spread and unite the people against them, so they strictly limited contact with the outside world. This is called Sakoku (National Isolation).

(1) Steps Toward Isolation

1. Prohibit Christianity (Edict on Religious Prohibition). 2. Prohibit Japanese people from traveling abroad and returning home. 3. Prohibit Portuguese ships from coming to Japan.
4. In 1641, the Dutch trading post was moved to Dejima in Nagasaki, completing the policy!

(2) The "Four Windows" Left Open

Japan wasn't completely shut off from the world. In reality, they kept four routes open for trade and diplomacy:
・Nagasaki: Trade with the Netherlands and China (Qing). ・Tsushima: Korea (the Joseon Tongsinsa diplomatic missions). ・Satsuma: Ryukyu Kingdom (modern-day Okinawa). ・Matsumae: The Ainu people (modern-day Hokkaido, etc.).

【Memorization Tip】 Just remember that "Even with isolation, the 4 windows of Nagasaki, Tsushima, Satsuma, and Matsumae stayed open!"

4. Development of Industry and New Culture

As peace continued, agriculture and business flourished, and a culture centered on townspeople (chonin) began to blossom.

(1) Economic Growth

In agriculture, tools like the "senba-koki" (thresher) appeared, leading to much larger rice harvests. Osaka became the hub where tax rice from all over the country was gathered, earning it the nickname "the Nation's Kitchen."

(2) Two Major Cultural Periods

・Genroku Culture: First half of the Edo period. It flourished mainly in Kamigata (Osaka and Kyoto). Famous works include Chikamatsu Monzaemon's puppet theater (ningyo joruri) and Matsuo Basho's haiku (The Narrow Road to the Deep North). ・Kasei Culture: Second half of the Edo period. It flourished mainly in Edo. Famous works include Katsushika Hokusai's ukiyo-e woodblock prints (Thirty-six Views of Mount Fuji) and Ino Tadataka's map of Japan.

【Key Point】 The shift from "Kamigata (Kansai)" in the first half to "Edo" in the second half is the defining feature!

Final Note: Mastering the Early Modern Era

At first, you might think, "There are so many names and years, it's too hard!" But history is like a puzzle.
"How did they unite Japan?" → "Nobunaga and Hideyoshi's ingenuity"
"How did they keep the peace?" → "The Shogunate's control over the daimyo"
If you focus on the reason (the story) behind why those rules were made, memorization becomes so much easier.

Don't rush—try looking up a warlord or a cultural trend that interests you first. I'm rooting for you!
