Studio Ghibli’s immortal masterpiece “Spirited Away.” The model for the impressive red bridge that appears in its fantastical world is said to be the “Kajika Bridge (かじかばし)” located in Ikaho Onsen in Shibukawa City, Gunma Prefecture. The landscape where the vermillion drum bridge that shines and nature in all four seasons intertwine is truly the world of the film itself. In this article, we will thoroughly introduce everything from the charm of Kajika Bridge to how to visit it and surrounding tourist spots—information that is a must-see not only for Ghibli fans but for everyone.
The Relationship Between Spirited Away and Kajika Bridge
The Model for the Red Bridge Leading to the Bath House
In “Spirited Away,” the bathhouse called “Yubaba’s Bathhouse” is where the protagonist Chihiro ends up working. The impressive red bridge that leads to its entrance appears many times in important scenes that symbolize the film. This bridge, depicted as a sacred bridge crossed by the gods, is said to be modeled after the Kajika Bridge in Ikaho Onsen.
Director Hayao Miyazaki is known to have conducted research on hot spring areas and historic structures throughout Japan during the production of this work. Ikaho Onsen is said to be one of these candidate locations, and it is believed that the vermillion railings of the Kajika Bridge and the natural environment surrounding it had a major influence on shaping the world of the film.
Why the Kajika Bridge is Said to Be the Model
There are multiple reasons why the Kajika Bridge is considered to be the model. First, its vivid vermillion railings and the shape of the drum bridge are strikingly similar to the bridge in the film. Second, the rich natural environment surrounding the bridge creates a mysterious atmosphere appropriate for expressing the world of the gods. Third, the overall hot spring atmosphere of Ikaho Onsen overlaps with the bathhouse world that serves as the setting for the film.
However, Studio Ghibli has not officially stated a specific model location. Nevertheless, many Ghibli fans and tourists visit and are moved by the similarities, so it is widely recognized as a sacred site from “Spirited Away.”
Basic Information and History of Kajika Bridge
What is Kajika Bridge
Kajika Bridge is a wooden drum bridge spanning near the hot spring source of Ikaho Onsen. At approximately 20 meters in length, the bridge is short, yet its presence is overwhelming. Its characteristic features are the vermillion-painted railings and the elegant curved shape of the bridge, which creates a beautiful landscape in harmony with nature in all four seasons.
The name of the bridge comes from the “kajika frog (Kajika Gaeru)” that inhabits the surrounding area. The kajika is a frog that lives in clear streams, and its beautiful calls have been beloved by Japanese people since ancient times. It is a tasteful name befitting the clear mountain streams of Ikaho.
Ikaho Onsen’s History and Kajika Bridge
Ikaho Onsen is one of the most renowned hot springs in the Kanto region, with a history of over 1,300 years. Its name is even mentioned in the Man’yōshū (Collection of Ten Thousand Leaves), indicating its long-standing fame since ancient times, and it was enjoyed as a healing center by many people during the Edo period. In particular, the unique structure of the hot spring town centered on the stone steps is said to have been organized by the Sanada clan during the Sengoku period.
The current form of Kajika Bridge was organized relatively recently, after the Showa era, but this location has long been an important point leading to the hot spring source of Ikaho Onsen. The construction of the vermillion bridge as an entrance to the sacred place where the hot spring source gushes forth is believed to have been intended to express the status and tradition of the hot spring area.
The Charm of Kajika Bridge Through All Four Seasons
Spring: The Season of Fresh Green
From mid-May to mid-June, the area around Kajika Bridge is enveloped in vibrant fresh greenery. The contrast between the green of young leaves and the vermillion bridge is beautiful, and you can enjoy a walk in refreshing air. This period also has relatively few tourists, making it easy to take photos at leisure.
The murmuring of the mountain stream and the chirping of birds echo throughout, truly allowing you to experience a sense of unity with nature. If you visit early in the morning, you may encounter a fantastical landscape enveloped in morning mist.
Summer: Seeking Coolness
In summer, Kajika Bridge is surrounded by dense green foliage, creating a refreshing atmosphere. Located at approximately 700 meters elevation, Ikaho Onsen is relatively comfortable even in summer and is popular as a summer retreat. The area along the mountain stream near Kajika Bridge is particularly cool, allowing you to forget the summer heat of the city.
If you’re lucky, you may hear the beautiful calls of the kajika frog, after which the bridge is named.
Autumn: A Spectacular View of Autumn Foliage
Kajika Bridge shines most beautifully during the autumn foliage season. The peak typically occurs from late October to early November, when the surrounding Japanese maples and other trees turn brilliant shades of red and yellow. The contrast between the vermillion bridge and the autumn foliage is breathtakingly beautiful, attracting many tourists and photographers.
Of particular note is the nighttime illumination that takes place during the autumn foliage season. The vermillion bridge floating in the darkness and the illuminated autumn leaves create a fantastical scene that is truly like the world of “Spirited Away.” Enveloped in a mysterious atmosphere, Kajika Bridge presents a completely different appearance than during the day.
The illumination is typically conducted during the period from late October to mid-November for a limited time, from sunset until around 10 p.m. (subject to change by year). Crowding is expected during this period, so it is recommended to visit in the early evening hours or on weekdays.
Winter: The Beauty of Silence
In winter, Kajika Bridge is quiet, with few visitors. On snowy days, the vermillion bridge stands out against the white winter landscape, creating scenery reminiscent of ink wash painting. While the cold is severe, the contrast between the steam from the hot springs unique to hot spring areas and the snowy landscape is a charm only winter can offer.
