What Is Senshu Park?
Senshu Park (Senshū Kōen) is Akita's signature historical park, created on the site of the former Kubota Castle in the heart of Akita City.
After the Battle of Sekigahara, Yoshinobu Satake, the first lord of the Akita Domain who was transferred from Hitachi to Akita, built Kubota Castle in 1603 (Keicho 8) by making use of the natural plateau of Mt. Shinmei, forming the foundation of the Akita castle town.
Kubota Castle was a hirayama-style castle built on a hill in a plain, without stone walls or a main keep, and it served as the residence of the Satake clan of 200,000 koku for 12 generations over 267 years.
In 1896 (Meiji 29), the site was developed into a park based on the design of Yasuhei Nagaoka, a pioneer of modern park design in Japan, and it was named "Senshu Park" by the Confucian scholar Ryōchi Kanō.
Today, Senshu Park is beloved by Akita residents and travelers alike as a place where water, greenery, and castle history can all be experienced together.
Historical Sights to See at Kubota Castle Ruins
The first place to visit is the Kubota Castle Main Gate (Omotemon).
This two-story turret gate served as the main entrance to the honmaru (central bailey) and was reconstructed in 2000 (Heisei 12) based on historical documents and archaeological research, still conveying the dignity of the castle's main gateway.
The Kubota Castle Osumi-yagura (Corner Turret), located at the northwest of the honmaru, is another must-see while walking through Senshu Park.
The Osumi-yagura served both as a watchtower and a "yagura" (weapons storehouse), and has been reconstructed as a two-story structure with the top floor arranged as an observation deck.
Inside the turret, panel exhibits introduce the history of the Satake clan, and from the observation deck on the top floor, visitors can enjoy a sweeping view of the Akita cityscape.
Opening hours are 9:00 a.m. to 4:30 p.m., and hours may be extended during events such as the Cherry Blossom Festival.
The turret is closed in winter.
The Kubota Castle Omonogashira-gobansho (guardhouse) is the only remaining government building from the feudal period within Kubota Castle, and is designated as a cultural property of Akita City.
Estimated to have been built between 1758 (Horeki 8) and 1778 (An'ei 7), it served as the office of the monogashira officials in charge of opening and closing the second gate (Nagasaka-mon), guarding the castle town, and fighting fires.
It is a valuable structure that deepens one's perspective of the castle site as a historical ruin.
If you would like to learn more about the Satake clan and the Akita Domain, visiting the Akita City Satake Historical Museum in the ninomaru (second bailey) will help you put everything in context.
Permanent exhibition admission is 500 yen for adults, and free for high school students and younger.
In addition to materials related to the Satake clan and the Akita Domain, the museum also offers video-based introductions.
Combining visits to the Satake Historical Museum, Osumi-yagura, and Omonogashira-gobansho makes it easy to see that Senshu Park is more than a simple walking spot; it is a place where you can explore Akita's history from multiple angles.
Enjoying the Four Seasons at Senshu Park
One of the biggest attractions of Senshu Park is how easily you can feel the changing of the four seasons.
The cherry blossoms are especially well-known: about 630 trees, mostly Somei Yoshino, have been planted throughout the park, making it one of Akita City's most famous cherry blossom spots.
It has been selected as one of "Japan's Top 100 Cherry Blossom Spots" by the Japan Cherry Blossom Association, and the blossoms usually reach peak bloom from mid to late April, with nighttime illumination during the Cherry Blossom Festival.
After spring, the lotus flowers in the moat are the next highlight to look out for.
In the moat of the Otemon (main gate), a lotus variety called "Gyozan Koren" blooms from around early July to mid-September, filling the water's surface with soft pale-pink flowers.
During summer, events related to the lotus are sometimes held, and the park is also popular as a nighttime walking spot.
In autumn, from late October to mid-November, zelkova and maple trees turn brilliant colors, and the combination of the Kubota Castle Main Gate with the fall foliage creates a picture-perfect scene.
In winter, starting in December, the trees in the park are fitted with yukitsuri (rope-and-pole snow protection), giving the park a distinctive snow-country atmosphere.
Since the same location looks completely different depending on the season, a good approach is to walk the entire park on your first visit, then return in another season to revisit your favorite spots.
An Easy-to-Follow Route Around Senshu Park for First-Time Visitors
If you are coming by train, Senshu Park is about a 15-minute walk from JR Akita Station to the ninomaru site, or about a 5-minute walk to Pocket Park.
It is easy to work into a stroll through the city center from the station, and this accessibility is one of Senshu Park's strengths.
If you have time, walk along the Otemon Moat Promenade (about 254 meters long and 3 meters wide) that opened in 2024 (Reiwa 6), enjoy the waterside scenery on the way in, then head up toward the honmaru to visit the Main Gate, Osumi-yagura, Omonogashira-gobansho, and Satake Historical Museum, allowing you to experience both nature and history comfortably.
The promenade is a floating-pier-style walkway designed as a new pedestrian route from JR Akita Station to Senshu Park, also aimed at enhancing lotus viewing and creating a welcoming waterside space.
Including visits to the museum and Osumi-yagura, touring the main sights typically takes about 2 to 3 hours.
The promenade is closed during winter (from December through March) and cannot be used after lights-out (from 10:00 p.m. to sunrise).
For evening walks, it is safer to use the regular park paths.
Etiquette and Things to Note Before You Visit
Senshu Park is a tourist attraction, but it is also a public park that is part of the daily lives of local residents.
Walking calmly, not blocking the paths, and yielding to others during busy times all help make for a pleasant visit.
Visitors are asked to avoid driving private cars into the park or parking in non-designated areas.
The use of open flames within the park is also prohibited, and on the Otemon Moat Promenade, bicycles, skateboards, scooters (including electric scooters), riding, smoking, collecting plants or animals, and feeding animals are not allowed.
Pre-school children must be accompanied by a guardian.
When visiting historical facilities, follow the instructions on the exhibits and from staff members.
