Mitsu Nature Observation Park, popularly known as the World Plum Garden, is located in Kurosaki, Mitsu-cho, Tatsuno City, Hyogo Prefecture. Opened in 1993, the park was developed to provide a welcoming place where local residents and visitors can relax, learn about nature, and enjoy outdoor recreation, while also supporting tourism and regional industry.
The park is home to approximately 1,250 plum trees representing 315 varieties collected from across East Asia, including Japan, China, South Korea, and Taiwan. This remarkable collection creates a colorful landscape during the flowering season and offers visitors the opportunity to appreciate the diversity of plum blossoms from different countries and regions.
The park has been designated as one of the Nishiharima Flower Villages, a regional initiative celebrating places known for their flowers and natural beauty. In spring, plum blossoms take center stage, accompanied by a variety of other flowers that bring color to the grounds.
One of the park’s distinctive features is its collection of Chinese-style buildings. Constructed by Chinese craftspeople, these structures introduce an atmosphere inspired by traditional Chinese architecture and give the garden an international character. The combination of flowering trees, landscaped grounds, and distinctive buildings makes the park a memorable place to explore.
Tobaikaku is one of the park’s signature structures and a symbol of its Chinese-style plum garden. Designed as an observation pavilion, it offers sweeping views across the Seto Inland Sea and the surrounding coastline.
In spring, the contrast between the blue sea and the plum blossoms in full bloom is especially beautiful. The combination of flowers, water, and distant islands creates a peaceful setting for photography and sightseeing.
Tobaikaku is a Chinese-style viewing structure designed to create an atmosphere reminiscent of traditional Chinese gardens. As one of the park’s central landmarks, it provides an excellent vantage point from which to enjoy the Seto Inland Sea and the surrounding landscape.
Shumbaikan is a museum dedicated to plum trees and their cultural significance. Exhibits introduce the history of plum cultivation, different varieties, and growing techniques. Visitors can learn how plum trees have spread across East Asia and the important role they play in horticulture and regional traditions.
Raikakuken is a rest facility established to promote friendship between Japan and China. Its Chinese-inspired architectural style complements the surrounding garden, while the peaceful setting provides a pleasant place to take a break and enjoy the scenery.

Baieha is an artistic feature in which the form of plum trees is depicted in the stone paving. As visitors walk through the garden, they can appreciate the design and the way it harmonizes with the surrounding trees and landscape, adding an artistic dimension to the traditional garden scenery.
On January 1, the park opens specially for visitors wishing to watch the first sunrise of the New Year, even though it is normally closed on that day. Many people gather to welcome the year in the peaceful surroundings and enjoy the first light appearing over the landscape.
The Mitsu Plum Festival is held every year on February 11 and marks the beginning of the plum-viewing season. Organized by the festival committee, local neighborhood associations, and Tatsuno City, the event brings together residents and visitors to celebrate the region’s seasonal flowers and local culture.
Festival highlights include food stalls featuring local specialties, particularly oysters from the area, as well as entertainment such as hero shows for children. The event offers a lively introduction to the plum season and is a popular occasion for families and visitors.
Admission is charged from February 11 through March 25 each year, during the main plum-viewing season. The park is free to enter during the rest of the year.
Regular opening hours are from 9:00 a.m. to 4:30 p.m. The park is normally closed on Mondays and from December 29 through January 3. Because the plum blossoms are a seasonal attraction, visitors planning a spring trip should check the flowering conditions before setting out.
