Odoi historic earthwork encircling Toyotomi's Kyoto city

On the ground today

Odoi (御土居) is encountered in Kyoto not as a single continuous wall but as scattered embankments, parks and parcel lines inside the modern city. Several surviving stretches are maintained in public or temple grounds, and portions were designated a national Historic Site in 1930 (eight locations) with one additional area added in 1965. You will find Odoi fragments on school grounds, in small parks and under the footprint of some shrine buildings; one section is within the Shōzan Kōetsu Art Village and another is preserved as an Odoi historic park.

From trains you can also glimpse traces: a surviving stone-faced section of Odoi is visible briefly from the San’in Main Line high bridge that crosses near the Seventh‑street route. The commonly repeated claim that JR Kyoto Station’s 0 platform sits atop Odoi fill is incorrect; that platform dates to 1914, though a 1993 excavation at the platform’s west end did recover a muddy layer interpreted as the remains of a former moat.

Where the ring ran: size and course

The original Odoi formed a vertically elongated ring around Kyoto with a north–south span of about 8.5 km and an east–west span of about 3.5 km; its total length measured roughly 22.5 km. The north end lay near present‑day northern Kita Ward close to the grounds of Kamo River Middle School; the south end lay just south of Tō‑ji in Minami Ward. The eastern line ran roughly along today’s Kawaramachi street; the western limit lay near the area of Enmachi Station on the San’in Main Line.

In parts the embankment made use of existing rivers as its outer ditch: the Kamo River on the east and the Shiyakawa (Tenjin River) on the northwest served as the moat in those sections. The line was not a simple rectangle — especially on the west side it shows several concave and convex turns. A small west‑side projection near present Kitano Middle School was long called the Odoi “sleeve.” Place names that mark old crossing points through the embankment survive in Kyoto: names such as Kuramaguchi, Tambaguchi, Awataguchi and Kojinguchi retain the memory of the former “mouths” where roads pierced the earthwork.

How it looked and what the surveys recorded

The first systematic scholarly survey of Odoi was carried out from 1918 to 1920 by the Kyoto Prefectural historic‑sites committee. Their measured cross section shows an earthwork in trapezoid form: a base about 20 metres wide, a top of about 5 metres and a height of roughly 5 metres. Outside the bank (or inside in some western stretches) ran a ditch whose width was a little over ten metres and whose depth reached about four metres at maximum. In many western stretches the ditch was simply the existing Shiyakawa; in the east the Kamo River played that role.

The embankment’s top was intentionally planted with bamboo. The Jesuit chronicler Luís Fróis reports that Hideyoshi ordered trees (bamboo) be planted for reasons of appearance. Archaeological finds also show that stone Buddhist images are occasionally recovered from within Odoi deposits; the source of those buried figures is not resolved by the records.

Why Hideyoshi built Odoi

Odoi was one of several large projects that accompanied Toyotomi Hideyoshi’s remodelling of Kyoto (alongside the Jurakudai palace, the Teramachi arcade and contemporaneous land redivisions). Contemporary and later documents recorded multiple rationales for its construction, and scholarship treats several functions as coexisting.

One clear role was to mark the boundary between the urban inner area (Rakuchu) and the surrounding countryside (Rakugai). A late chronicle preserves a tradition that Hideyoshi sought to define the city’s bounds after unification; the area enclosed by Odoi became the frame by which later land surveys and tax decisions treated “inside” and “outside.” Records of surveys and of a 1591 (Tensho 19) exemption of certain land taxes show administrative consequences tied to whether land lay within that ring.

Odoi also carried hydraulic and landscape functions. Its eastern run beside the Kamo River served as a flood embankment: the long northward reach of the bank was intended to keep floodwaters from entering the city in that sector.

Scholars have long debated its military meaning. Odoi resembles the medieval practice of enclosing towns with a defensive ring, yet several features complicate an interpretation of Odoi as a purely military curtain wall: it enclosed an area far larger than the contemporary urban core (increasing the length to man); the bamboo on top impaired sightlines and troop movement; contemporary maps show gate openings without the kinds of obstructing works used in castle fortifications; and in part of the western line an inner moat layout would have made holding the embankment tactically awkward. For these reasons researchers treat defensive, administrative, landscape and traffic‑control purposes as overlapping intentions rather than a single exclusive aim.

The earthwork could also restrict or channel rites and movement tied to major shrines. For example, bridges and river crossings used for access to the Gion shrine were removed at construction and required temporary rerouting until a new passage was opened in 1601.

Later history: Edo, Meiji and preservation

Construction began in January 1591 (Tensho 19, including the intercalary month) and by February of the same year the bulk of the work was reportedly complete. After Hideyoshi’s death and the Tokugawa takeover, many segments that had blocked roads were removed and numerous new openings were cut; a blocked section near today’s Shijo Kawaramachi was taken out in 1601. Along the Kamo River the development of the Takase River and riverside commerce pushed the urban line outward and, after the completion of a new bank in 1670, parts of Odoi were sold to temples and aristocratic households or otherwise redeveloped.

During the Edo period the remaining embankments were often managed as bamboo groves. From 1669 to 1791 the Sumino‑kura family managed much of the Odoi; later the town magistracy assumed direct control. In the Meiji years and into the Taisho era, municipal expansion and housing development removed many stretches. To protect what remained, eight Odoi fragments were designated a national Historic Site on 8 July 1930; an additional fragment was added to the protected range on 27 October 1965. Even after designation, the 1960s saw further loss from development, and a July 9, 1967, landslide triggered by heavy rain destroyed about 100 metres of a surviving stretch.

Surviving fragments and place names to look for

The 1930 / 1965 Historic‑Site designations name several surviving fragments across Kyoto wards. Notable locales called out in the designation or later documentation include sections in Kita Ward (including stretches near the grounds of Kamo River Middle School, the Omiya Doicho area, parts preserved inside the Shōzan Kōetsu Art Village and an Odoi historic park), Nishino Doicho and Hirano Torii‑mae‑cho; a stretch in Kamigyo Ward at the Rozanji area; and a segment in Nakagyo Ward where a shrine occupies the Odoi top. The 1965 addition protects a fragment within the precincts of Kitano Tenmangu in Kamigyo Ward. Other surviving traces appear in school yards such as the Kitano Middle School site and in small municipal parks like Omiya Traffic Park. Several Kyoto street and district names (for example variants of “Doicho,” “Nishidoi,” and related road names) preserve the embankment’s memory, and in places ward boundaries still track the old Odoi line.
