What is “Kokosake”? A Moving Anime Set in Chichibu City, Saitama Prefecture
“Koko ga Sakebe Kitai Yatterun da.” (commonly known as “Kokosake”) is an animated film released in 2015. With a screenplay by Okada Mariko and direction by Nagai Tatsuya, this work garnered significant attention when the staff from “Anohana: The Flower We Saw That Day” reunited once again.
The setting of the story is Chichibu City, Saitama Prefecture. Despite being located just about 2 hours from central Tokyo, Chichibu is a fascinating region with rich natural beauty and historic streetscapes. In “Kokosake,” actual landscapes of Chichibu are depicted carefully, and after the film’s release, many fans began visiting for sacred site pilgrimages.
The work is a youth ensemble drama centered on Naruse Jun, a girl who has lost the ability to speak due to childhood trauma, depicting the conflicts and growth of high school students. Chichibu’s beautiful scenery becomes an important backdrop to the story, richly expressing the emotional states of the characters.
Why Chichibu City Was Chosen as the Setting for “Kokosake”
Chichibu City was chosen as the setting for “Kokosake” for several reasons.
First, the production staff had already used Chichibu as the setting for the previous work “Anohana,” and a relationship of trust with the region had already been established. Chichibu City was also proactive in anime tourism from a regional revitalization perspective and was cooperative in providing filming support and information.
Next is the geographical characteristics of Chichibu. The landform of a basin surrounded by mountains matches perfectly with the sense of confinement the main characters feel and the structure of the story in which they are freed from it. In particular, the view of the city below from Chichibu Muse Park is effectively used in important scenes of the work.
Furthermore, Chichibu City has a good balance of historical buildings, natural landscapes, and modern facilities, functioning as a setting for diverse scenes. Hot spring districts, shrines and temples, schools, residential areas—all the elements needed for the story were conveniently located within walking distance.
“Kokosake” Sacred Site Pilgrimage: Complete List of Must-See Spots
Chichibu Muse Park
Chichibu Muse Park is the most iconic filming location in “Kokosake.” In particular, the view from the observation deck was used in the film’s poster and key visuals, making it an unmissable sacred site for fans.
Within the park is a concert hall, which is said to be modeled after the venue where the main characters perform a musical in the film. The vast grounds feature scenic walking trails and sports facilities, allowing you to enjoy not just the sacred site pilgrimage but also leisurely strolls.
The park offers beautiful scenery throughout the seasons—cherry blossoms in spring, fresh greenery in early summer, and autumn leaves in fall. The scenery at dusk is particularly special, evoking the film’s atmosphere, and many fans visit to take photographs.

Chichibu Shrine
Chichibu Shrine appears in scenes where the main characters visit for New Year’s prayers. This shrine, with over 2,000 years of history, is revered as the guardian shrine of the Chichibu region.
Within the grounds is the main hall, said to have been reconstructed by Tokugawa Ieyasu, featuring elaborate carvings. In particular, the carvings of the “Dragon of Unity” and “Tiger of Child-Rearing” are must-sees. The Chichibu Night Festival is held in December and is one of Japan’s three major wagon festivals, attracting many visitors.
Combined with “Kokosake” sacred site pilgrimage, this is an important spot where you can experience Chichibu’s history and culture.

From the bridge, you can take in a panoramic view of Chichibu’s mountains and the clear waters of the Arakawa River, making it an excellent photo spot to experience the world of “Kokosake.” The scenery is especially beautiful at dusk, evoking memorable scenes from the film.
Near the bridge, walking trails have been developed, allowing you to enjoy Chichibu’s nature while strolling along the riverbank.

Hitsujiyama Park
Hitsujiyama Park is located on a small hill overlooking Chichibu’s city center and is depicted as a place the characters visit in the film.
It is particularly famous for the “Shibazakura (Moss Phlox) Hill,” where approximately 400,000 moss phlox flowers bloom in spring, covering the hillside in a colorful tapestry of pink, white, and purple. This is Chichibu’s iconic spring sight.
The park also features a viewpoint called “The Scenic Outlook,” offering panoramic views of Chichibu’s city center and Mount Buko. You can immerse yourself in the world of “Kokosake” while enjoying Chichibu’s natural beauty.
Access: About 20 minutes on foot from Seibu-Chichibu Station, or about 20 minutes on foot from Mishihana Station on the Chichibu Railway

Around Chichibu Municipal Hospital
The area around Chichibu Municipal Hospital, said to be modeled after the hospital depicted in the film, is also a sacred site pilgrimage spot. However, since it is an active medical facility, please view only the exterior quietly when visiting.
The atmosphere of the surrounding residential streets is faithfully reproduced in the work, allowing you to feel the daily lives of the main characters.
Note: Since the hospital is a medical facility, please refrain from entering the grounds or speaking loudly.
Various Stations on the Chichibu Railway
The stations and trains of the Chichibu Railway also appear in the film. In particular, Mishihana Station (Shibazakura Station) and Chichibu Station are depicted as the route the main characters take to school.
The retro atmosphere of the station buildings and the trains running through pastoral countryside are emblematic of “Kokosake’s” world view. We also recommend actually riding the Chichibu Railway to enjoy the same scenery as the characters in the film.
The Chichibu Railway also operates the SL Paleo Express (limited to operating days), which is also popular with railway enthusiasts.
Shopping Streets in Chichibu City Center
Chichibu’s city center retains old-fashioned shopping streets and appears in the film as part of everyday scenery. Walking through streets like Banba-dori or Honmachi-dori will make you feel as if you’ve stepped into the world of “Kokosake.”
There are many local Japanese confectionery shops and restaurants, so you can enjoy Chichibu cuisine during your pilgrimage. Be sure to try Chichibu’s specialty dishes such as wara waraji katsudon (large breaded pork cutlet), Chichibu soba, and miso potatoes.

The weather is also stable, making autumn one of the most suitable seasons for sacred site pilgrimages. Particularly from October to November, you can comfortably enjoy walking tours.
Winter (December-February)
Chichibu winters are cold, but the air is clear and scenery particularly beautiful. Especially the view from Chichibu Muse Park at dusk has a winter-specific transparency.
