Introduction: The Walled City in a Mountain Town

"Attack on Titan" (進撃の巨人 / Shingeki no Kyojin) — Hajime Isayama's manga (2009–2021) and its anime adaptation — is set in a world where humanity survives inside enormous walled cities defending against gigantic human-eating titans. The visual design of the series draws on specific real-world sources, and the pilgrimage community has documented these sources with considerable thoroughness.

Hajime Isayama was born and raised in Ōyama Town (大山町), now part of Hita City (日田市) in Oita Prefecture — a fact that establishes the primary seichi connection between the series and a real place that most international Attack on Titan fans have never heard of.

Hita City: The Hometown Connection

Hita City has embraced its connection to the world's most-read manga with a specific combination of local pride and tourism development. Several permanent installations make the city a legitimate pilgrimage destination:

The Isayama Hometown Visit (出身地の日田): The neighborhood of Ōyama where Isayama grew up — now featuring mounted illustrations and explanatory signage connecting the physical landscape to the manga's visual development.

Hita City Museum (日田市内の施設): Local exhibitions covering Isayama's upbringing and the development of Attack on Titan, with some original art and documentation.

Wall Maria Gate (壁マリアの門): A recreation of the distinctive arched gates of the manga's walled city, installed as a permanent landmark at a key point in Hita city — the visual centerpiece of the dedicated seichi experience.

Levi Sculpture: A large bronze statue of the character Levi Ackermann (one of the most popular characters in the series) installed in Hita, specifically as a pilgrimage anchor point.

The European Architectural References

Attack on Titan's fictional world is visually referenced to central European medieval architecture — specifically the Germanic half-timbered buildings (Fachwerk / 木骨構造) of towns like Quedlinburg (Germany) and Colmar (France). These European architectural references were intentional choices by Isayama to create a specific cultural distance from typical anime visual vocabulary.

For pilgrims interested in the visual architecture of the series rather than the biographical connection:

Nagasaki's Huis Ten Bosch (ハウステンボス): The Dutch-themed theme park near Nagasaki, whose brick-and-gabled architectural environment closely resembles the series' visual tone — not a source reference, but the closest physical analogue available in Japan to the series' aesthetic.

Additional Referenced Locations

Tomonoura (Hiroshima)

The historic port town of Tomonoura — covered in the dedicated article — shares certain visual characteristics with the manga's harbor town of Trost District, and some fan analysis has identified it as a potential reference location, though the connection is more interpretive than the biographical Hita connection.

The Oita Pilgrimage Circuit

Combining Hita City with the Oita Prefecture's other major attractions (Beppu, Yufuin — both covered in dedicated articles) creates a natural travel circuit for Attack on Titan fans visiting Kyushu, with the pilgrimage element complemented by the region's onsen culture.
