작은 어촌이었던 도쿄는 어떻게 일본의 수도가 됐을까?｜개꿀잼 세계사

Overview

The video explains how Edo (modern Tokyo), once a remote rural backwater, became Japan’s de facto capital despite Kyoto and Osaka being long-established centers.

Historical Imbalance (Kansai vs. Edo)

For much of Japan’s history, the Kansai region—especially Kyoto and Osaka—was the cultural and economic center because it had favorable agriculture and easier trade with China and the Korean Peninsula.

By contrast, Edo (Tokyo) was comparatively underdeveloped—described as dense bamboo with only about 100 houses.

Power Consolidation in the Late 16th Century

The shift begins during Japan’s unification era under Toyotomi Hideyoshi. Hideyoshi expands control over regional powers, including the Hojo.

However, he distrusts Tokugawa Ieyasu (partly because they had been enemies). To keep Ieyasu contained, Hideyoshi relocates him, stripping his existing domain and giving him the Kanto region, connected to the former Hojo lands.

Choosing Edo Strategically

After Hideyoshi’s death and the outbreak of the Imjin War, Ieyasu rises to power as shogun. He decides the shogunate’s center should be Edo, not Kansai.

The video argues this was deliberate and based on several advantages:

• Land and agricultural potential: The Kanto region is described as a vast fertile area (referred to as a large “Pyongyang” in the subtitles), though at the time it is wetland-covered, implying it could be reclaimed and developed for farming.
• Transport and logistics: Edo sits on an estuary with many rivers feeding into it, plus access to the sea to the east, supporting supply transport.
• Political distance from old power: Centering authority in Edo while keeping Kyoto at a safe distance helps reduce interference from traditional power structures tied to the court.
• Military defensibility: Edo is protected by Hakone Pass (described in the subtitles as steep and slippery terrain), making it hard for rebel forces from the west to reach the capital region on horseback.

Urban Development and Rapid Growth

Ieyasu’s administration improves waterways and builds canals to manage flooding and expand farmland. As a result, Edo rapidly increases in value and population, reaching over one million by the 18th century—larger than major European and Asian cities such as Paris, London, or Beijing (per the subtitles).

Notably, Kyoto remains the official capital, and the emperor continues to reside there.

Meiji Restoration and the “East Capital” Compromise

In 1868, the Edo shogunate collapses due to the Meiji Restoration. The new government faces a dilemma:

• Kyoto is the historic official capital
• Edo has become the real center of Japan

They keep Kyoto as the capital while making Edo the capital of the east, leading to the renaming of Edo to Tokyo (“capital of the east”). Thus, Tokyo becomes the de facto (functional) capital, while Kyoto remains symbolic.

Overall Conclusion

The video frames Edo’s transformation as the outcome of strategic leadership, infrastructure and logistics development, and political design—likening the planning to a “SimCity” enthusiast mindset: turning a bamboo-covered backwater into Japan’s practical capital.
