The anime Demon Slayer: Kimetsu no Yaiba is set in the Taisho Era (1912–1926), a time of rapid modernization mixed with strong traditions. This unique cultural fusion is vividly expressed through the contrast between the Demon Slayer Corps in traditional attire and Muzan Kibutsuji surrounded by Western modernity. Understanding this era helps foreign viewers fully grasp the depth of the story’s atmosphere and themes.

What Was the Taisho Era Like?

The Taisho Era refers to the 14 years from 1912 to 1926. The Western culture introduced during the Meiji Era spread further in cities, where people in kimonos and those in Western suits walked side by side. Gas lamps and electric lights illuminated the streets, while trains and automobiles became part of daily life, shaping modern urban culture.

In contrast, rural areas still retained traditional lifestyles, creating noticeable differences in culture and values depending on region. Politically, the era is known for “Taisho Democracy”, where liberal ideas spread through newspapers and magazines, stimulating public debate. However, events such as the Great Kanto Earthquake and World War I shook people’s lives and kept society under constant tension.

How the Fusion of Japanese and Western Elements Shapes the Story

One of the key charms of Demon Slayer is its unique world where Japanese and Western influences coexist. The Demon Slayer Corps wears kimonos and wields swords, representing the spirit of samurai and Japan’s traditions. In contrast, Muzan Kibutsuji favors Western suits and lives in a Western-style mansion, symbolizing Western modernity.

This contrast is not just for aesthetics but reflects the tension between tradition and modernity in society. For foreign audiences, the juxtaposition of Japanese aesthetics with Western styles leaves a striking impression and serves as a gateway to understanding Japan’s layered cultural identity.

The Taisho Era as an Age of Change and Conflict

The Taisho Era was truly an era of change and conflict. The post-World War I economic boom ended quickly, leaving behind recessions and social unrest. In 1923, the Great Kanto Earthquake devastated the capital, destroying infrastructure and altering urban life.

In Demon Slayer, demons are not depicted as simple evil beings, but as entities born from human suffering and despair. This mirrors how rapid social changes left many unable to adapt, creating inner turmoil. Meanwhile, the protagonists bear the weight of family bonds and traditions while also being forced to make their own choices about the future. This tension between tradition and individuality strongly resonates with the lived experience of people in the Taisho Era.
