About Nikko Botanical Garden
Nikko Botanical Garden, formally known as “Nikko Branch Garden, Botanical Garden, Faculty of Science, Graduate School of Science, Tokyo University,” is an educational and research facility affiliated with Tokyo University, established for the purpose of plant science education and research. As a branch garden of the Koishikawa Botanical Garden in Bunkyo Ward, Tokyo, it was opened near the Toshogu Shrine in 1902 (Meiji 35) and relocated to its current location in 1911 (Meiji 44). With over 100 years of history, this botanical garden continues to serve as an important center for academic research, taking advantage of Nikko’s favorable natural environment.
Location and Natural Environment Characteristics
Nikko City in Tochigi Prefecture, where Nikko Botanical Garden is located, is blessed with diverse natural environments, including mountains over 2,000 meters in elevation such as Mt. Nantai, Mt. Nannei, and Mt. Shirane; various lakes and wetlands including Lake Chuzenji; and wetland areas like Senjogahara and Odashiro-hara. These favorable location conditions enable the botanical garden to cultivate alpine plants and cool-climate plants in environments close to their natural habitats.
The vast grounds, covering approximately 106,980 square meters (approximately 32,361 tsubo), house plants that grow naturally in Nikko and those from temperate to subarctic regions, maintaining a total of approximately 2,200 plant species, including about 130 species of ferns, approximately 70 species of gymnosperms, and about 2,000 species of angiosperms.
Highlights and Attractions of Nikko Botanical Garden
Collection of Alpine Plants and Cool-Climate Plants
The greatest feature of Nikko Botanical Garden is its comprehensive display of alpine plants and cool-climate plants, taking advantage of Nikko’s cool climate. The ability to observe rare plants that normally can only be seen at high elevations in a relatively accessible environment is a unique charm of this botanical garden.
Within the garden, alpine plants that would normally require climbing difficult mountains can be observed up close, making it a valuable learning venue for those for whom mountain climbing is difficult and for plant enthusiasts. While maintaining the academic character and old-fashioned atmosphere of a traditional botanical garden, the displays are organized to be enjoyed by general visitors as well.
Seasonal Plant Highlights
Spring (April–May)
Nikko Botanical Garden opens in mid-April, and spring is the most vibrant season. Skunk cabbage reaches its peak in mid-April, with pure white flowers enchanting visitors. Cherry blossoms also bloom, spreading landscapes typical of spring’s arrival. From early May onward, plants throughout the garden simultaneously enter their flowering period, allowing visitors to enjoy flowers in a multitude of colors.
During this period, the greatest variety of flowers bloom throughout the year, making it the most crowded season at the botanical garden. Combined with the beauty of fresh green foliage, this is a special time that allows visitors to feel the vitality of spring.
Early Summer (June–July)
In June, Japanese irises and water irises reach their peak. Purple and blue flowers blooming on the water’s edge create a beautiful landscape symbolizing early summer in Japan. Additionally, day lilies begin to bloom, adding bright colors to the garden.
Though this is also the rainy season, the sight of plants wet with rain has its own charm, allowing visitors to enjoy the moist atmosphere of the botanical garden.
Summer (August–September)
Summer provides a comfortable walking environment through Nikko’s cool climate. Due to the high elevation, it remains more pleasant even in midsummer compared to urban areas like Tokyo, making it ideal for plant observation combined with summer retreat. With approximately 100 plant species in constant bloom at any given time, visitors can enjoy some flowers regardless of when they visit.
Autumn (October–November)
From early October through late November is the foliage season, when Nikko Botanical Garden enters its most colorful period of the year. Cherry tree foliage begins in early October, followed by the yellow leaves of katsura, witch hazel, beech, and oak. As late October approaches, the foliage of maple and azalea species progresses, transforming the garden into shades of red, yellow, and orange.
During the foliage season, experiencing the varied colors, shapes, and scents of fallen leaves from various plants is a unique pleasure of Nikko Botanical Garden. The ability to observe foliage from a botanical perspective allows visitors to learn about plant ecology, not merely appreciate scenic beauty.
Winter (December–March)
Nikko Botanical Garden is closed during winter (December 1 – April 14). This period coincides with plant dormancy, and snow and freezing conditions make safe pathway maintenance difficult. Winter closure is a measure to protect plants and ensure visitor safety.

Nikko Botanical Garden opened in 1902 (Meiji 35) near Toshogu Shrine. From its inception, it was established as an affiliated facility of Tokyo University (then Tokyo Imperial University) for the purpose of plant science education and research. Following its relocation in 1911 (Meiji 44) to the current location in Hanaishi-cho, it has contributed to plant science research in Japan for over 100 years.
Role as an Educational and Research Facility
Nikko Botanical Garden serves as an important educational training facility for Tokyo University students. Practical training in plant taxonomy, plant ecology, plant physiology, and other subjects is conducted, allowing students to deepen their specialized knowledge through observation of actual plants.
It also plays an important role as a research facility, with studies on the ecology and conservation of alpine and cool-climate plants being conducted. Research utilizing Nikko’s climate conditions contributes to clarifying the impacts of climate change on plants.
Significance of Public Access
While serving as an academic research facility, Nikko Botanical Garden’s public opening fulfills the important role of promoting plant science among citizens. As a venue where the results of specialized research can be experienced by the general public, it holds high value from a scientific education perspective.
Like Koishikawa Botanical Garden, it maintains the academic character and traditional atmosphere of a classical botanical garden while remaining open to all people interested in plants.
Precautions and Etiquette During Visits
Clothing and Belongings
Since Nikko Botanical Garden has vast grounds covering approximately 105,000 square meters, comfortable walking shoes are recommended. As the terrain is uneven, sneakers or athletic shoes are appropriate.
