Kaiseizan Park (Fukushima Prefecture) Complete Cherry Blossom Guide | Japan’s Oldest Somei Yoshino and 1,300 Cherry Blossoms
Kaiseizan Park in Koriyama City, Fukushima Prefecture, is known as one of the prefecture’s premier cherry blossom viewing spots. The cherry tree-lined paths, nurtured alongside the history of Asaka land reclamation during the Meiji era, continue to captivate many hanami visitors today. This article provides detailed information to help you enjoy cherry blossom viewing at Kaiseizan Park, from the charm of the blossoms to the best viewing seasons and access methods.
Kaiseizan Park Overview | Cherry Blossoms Blooming at the Foundation of Koriyama’s Development
Kaiseizan Park is the city’s largest comprehensive park, located near the center of Koriyama City. Centered around Isuzu Lake, the approximately 30-hectare grounds feature an outdoor music hall, baseball fields, track and field stadiums, and rose gardens, serving as a gathering place for citizens throughout the year.
Symbol of Asaka Land Reclamation
The history of Kaiseizan Park traces back to the Asaka land reclamation project in the early Meiji era. Launched as part of the samurai stipend policy following the Meiji Restoration, the Asaka reclamation became a major undertaking that laid the foundation for Koriyama’s development. The cherry trees planted by the Kaisei-sha company in Meiji 11 (1878), which promoted this reclamation project, are among Japan’s oldest Somei Yoshino cherry trees, some of which remain in the park today.
Due to this historical value, Kaiseizan Park’s cherry blossoms are designated as constituent cultural properties of the Japan Heritage site “The Water Route That Opened the Future,” giving them cultural significance that transcends being merely a cherry blossom viewing spot.
Japan’s Oldest Somei Yoshino | Characteristics of Kaiseizan Park’s Cherry Blossoms
What sets Kaiseizan Park apart from other cherry blossom viewing spots is the presence of among Japan’s oldest existing Somei Yoshino cherry trees.
Historical Value of Trees Planted in Meiji 11
The Somei Yoshino planted in Meiji 11 (1878) is considered among the oldest existing specimens. The Somei Yoshino variety began to spread from the late Edo period through the early Meiji era, and the trees at Kaiseizan Park are precious individuals planted during this early period. Despite more than 140 years passing, these trees continue to produce beautiful blossoms—they are living witnesses to the history of Asaka land reclamation.
A Landscape Woven by Approximately 1,300 Cherry Trees
Combined with the adjacent Kaiseizan Daijingu Shrine, approximately 1,300 cherry trees are planted in the area. About 1,100 are in the park itself, with roughly 200 at Kaiseizan Daijingu Shrine, the majority being Somei Yoshino. Additionally, Yamato cherry and Kanzan (a variety of double-flowering cherry), among others, are also planted, allowing visitors to enjoy cherry blossoms over extended periods due to their different blooming times.
The cherry blossoms blooming around Isuzu Lake and along park paths create a tunnel-like landscape. Especially at full bloom, the blossoms covering the sky create breathtaking beauty, and the spot is known for being used as a filming location for the movie “The Girl Who Leapt Through Time.”
Kaiseizan Park Cherry Blossoms | Typical Peak Season and Bloom Period
The cherry blossom bloom timing in Koriyama City, Fukushima Prefecture, varies somewhat year to year depending on climate conditions, but understanding typical patterns allows you to plan an optimal visit.
Typical Peak Season
Kaiseizan Park’s cherry blossoms typically reach their peak from early April to mid-April. Specifically, the general schedule is as follows:
- Bloom period: Early April (around April 5)
- Full bloom period: Mid-April (approximately April 10-15)
- Peak viewing period: Approximately one week from full bloom
The bloom period varies depending on temperature trends, so it’s recommended to check the latest bloom forecasts and current bloom status before visiting. In recent years, a trend toward earlier blooming due to global warming has been observed.
Differences in Bloom Timing by Cherry Tree Variety
While Somei Yoshino forms the main body of Kaiseizan Park, Yamato cherry and the double-flowering Kanzan are also planted, allowing visitors to enjoy cherry blossoms even after the Somei Yoshino peak season passes. Kanzan produces deep pink double flowers from late April to early May, making it possible to view cherry blossoms during the Golden Week period.
Night Cherry Blossoms and Illumination Information at Kaiseizan Park
During the cherry blossom season at Kaiseizan Park, nighttime illuminations are conducted, allowing visitors to enjoy an enchanting atmosphere different from daytime viewing.
Illumination Period and Hours
In coordination with cherry blossom bloom status, illuminations are typically held from early to mid-April. The illumination hours are generally from sunset to around 9:00 PM. However, since implementation periods and times may change from year to year, it’s recommended to check the latest information from Koriyama City’s official website or the tourism association before your visit.
Night Cherry Blossom Viewing Highlights
Illuminated cherry blossoms reveal a refined beauty different from their daytime brilliance. The sight of blossoms reflected in Isuzu Lake’s water surface is particularly beautiful and popular for photography. Additionally, the lantern light of food stalls along the Kaiseizan Daijingu approach, combined with the cherry blossom illumination, creates a festive, celebratory atmosphere.
When viewing night cherry blossoms, temperatures often drop, so bringing an outer garment for warmth allows for more comfortable enjoyment.

Kaiseizan Daijingu Shrine, adjacent to Kaiseizan Park, is also known as a cherry blossom viewing spot. Visiting both together provides a more enriching hanami experience.
About Kaiseizan Daijingu Shrine
Kaiseizan Daijingu Shrine was founded in Meiji 9 (1876) by enshrining a branch spirit from Ise Grand Shrine and is affectionately known as “the Ise Shrine of Tohoku.” It was established as the spiritual pillar of the Asaka land reclamation project and, together with Kaiseizan Park, symbolizes Koriyama’s history.
Food Stalls Lining the Approach
