Quick answer: Tokyo's two best-known botanical gardens are Koishikawa Botanical Gardens in Bunkyo Ward, run by the University of Tokyo, and Jindai Botanical Garden in Chofu. Koishikawa is known for its history and research collections, while Jindai is known for roses and seasonal displays. Both charge a modest admission fee and are closed on Mondays, so check the official pages before visiting.

Two gardens, two characters

Koishikawa Botanical Gardens and Jindai Botanical Garden are the two gardens that most visitors mean when they search for a botanical garden in Tokyo. They share a Monday closing day and a modest admission fee, but they feel different. Koishikawa is a research and teaching garden in the middle of the city, with a long history. Jindai is a large public garden in the western suburbs, organized around areas of related plants.

Both are good choices when you want a slower day. They suit travelers who like trees, flowers and quiet paths more than famous landmarks, and they work for a morning or an afternoon. Choosing between them often comes down to location and season, and the sections below explain what each offers.

Koishikawa Botanical Gardens

Koishikawa is run by the Graduate School of Science at the University of Tokyo as a teaching and research facility for botany. The garden's own site says it began as the Koishikawa Oyakuen, a medicinal herb garden run by the Tokugawa shogunate from 1684, and that it became a University of Tokyo garden in 1877. The garden's site calls it the birthplace of modern botany in Japan, with about 161,588 square meters of grounds and roughly 4,000 plant species. According to Wikipedia, it was designated a National Historic Site and a National Place of Scenic Beauty in 2012.

The official site names several highlights: a medicinal herb garden, a camellia garden, an azalea garden, a glasshouse, a cool temperate house, Somei-Yoshino cherry trees and a plum grove, along with an apple tree grafted from one linked to Newton and a grapevine linked to Mendel. The address is 3-7-1 Hakusan in Bunkyo Ward, and the garden's access page has directions. The site also notes that it is a botanical garden and not a general park.

Jindai Botanical Garden

Jindai Botanical Garden is in Chofu, on the edge of the Musashino plateau just above Jindaiji Temple. According to Wikipedia, it has thirty areas, each devoted to one type of plant, and a large greenhouse built in 1984 that holds tropical plants. Wikipedia says it received its current name in 1961. It also describes a wetland annex that grows aquatic plants such as irises.

Jindai is especially known for its rose garden, and the large greenhouse houses tropical plants. Exact plant counts and the layout of the displays are updated by the garden, so use its current visitor information for details.

Seasonal highlights

Jindai is usually described as rewarding across the year. Spring is the classic season for cherry blossoms, azaleas and roses, summer suits water plants such as irises and lilies, autumn brings turning leaves, and winter brings plum blossoms and camellias. Roses are the best-known draw and typically bloom in late spring and again in autumn, though exact timing depends on the weather, so check the garden's notices before traveling.

Koishikawa's site has a What's in Bloom page with current flowering and autumn foliage updates, which is the best way to time a visit. Its camellia garden, azalea garden, cherry trees and plum grove suggest that late winter and spring are rewarding, and autumn foliage is covered there too. Because blooms depend on the weather, a quick check before leaving prevents disappointment.

Hours, admission and rules

Koishikawa's visitor guide gives opening hours of 9:00 a.m. to 4:30 p.m., with last entry at 4:00 p.m. The garden is closed on Mondays and, according to the guide, open from January 4 to December 28. Adult admission is listed at 500 yen and 150 yen for children, with free entry for children under six and on May 4, and re-entry is not allowed after you leave. Check the official pages for current prices.

The visitor guide also lists separate hours for some buildings: the greenhouse is listed as open from 10:00 a.m. to 3:00 p.m., which is shorter than the garden itself. If the glasshouse is a priority, plan to reach it well before mid-afternoon. The Shibata Memorial Hall on the grounds is listed with its own hours of 10:30 a.m. to 4:00 p.m., and the garden's site notes a herbarium of about 800,000 specimens at the university, which shows how much research stands behind the plantings.

Wikipedia lists Jindai's hours as 9:30 a.m. to 5:00 p.m., with the ticket window closing at 4:00 p.m., and says it is closed on Mondays (the following day when Monday is a national holiday). The same page lists adult admission at 500 yen, with lower prices for children and seniors, as of early 2024. It is also usually closed around the New Year holidays. Both gardens publish additional rules on their sites, so read them before you go.

Rules, pets and picnics

Koishikawa's general information page says pets and other animals are not allowed, though guide dogs and service dogs are exempt. It also asks visitors not to collect or damage plants or animals, and lists smoking, drinking alcohol, tents, drones, musical instruments and model shoots among the prohibited activities. Eating and drinking (except alcohol) is permitted, and visitors take their trash home, so a quiet snack or packed lunch is fine.

Many paid gardens in Tokyo do not admit pets, and smoking is usually limited to designated areas, so check Jindai's current rules on its official page. Picnic rules at Jindai could not be confirmed here, so look for signs on site and the garden's current notices rather than assuming picnics are allowed. Visitors who need a wheelchair, a stroller or other assistance should contact the garden before traveling to ask what is available, since facilities and loan arrangements can differ between gardens and change over time.

Choosing and combining visits

Choose Koishikawa if you want a history-rich garden in central Tokyo, and Jindai if you want roses, a large greenhouse and an excursion to the western suburbs. Wikipedia notes that from Chofu Station a bus runs to the garden in about ten minutes, and the temple next door makes a natural pairing.

For a relaxed day, arrive close to opening, walk the main paths first and leave time for the greenhouse. Bring water, a hat in summer and comfortable shoes. Because blooms, hours and fees can change, look at each garden's official page on the morning of your visit.
