Walk a few minutes from Meguro Station along the traffic-filled Meguro-dori, turn in through an unassuming gate, and the noise of the city is soon swallowed by the trees: this is the Institute for Nature Study (Shizen Kyoikuen), attached to the National Museum of Nature and Science, in Shirokanedai, Minato Ward, Tokyo.
It is not a carefully pruned Japanese garden but a green space in the heart of the city where the forest is deliberately left to grow and age on its own, which is why its autumn leaves carry a wildness you would normally only find in the mountains.
Every year from late November, the Japanese maples (iroha momiji), wax trees (hazenoki) and witch hazel in the grounds turn red and yellow one after another, mingling with the evergreen chinquapin woods for colours more layered than in an ordinary park.
The questions people ask most when planning are: when are the autumn leaves at the Institute for Nature Study at their best? How do you walk there from Meguro or Shirokanedai? Can you go on a Monday, and do you need cash for the entrance fee?
This article draws on information published by the Institute for Nature Study and the Japan Weather Association’s tenki.jp to explain the autumn-leaf season, the must-see spots in the grounds, opening hours and fees, access and nearby itineraries all in one place.
If you are planning an autumn walking itinerary in central Tokyo, by the end you will be able to decide which day to fit in the Institute for Nature Study and which spots to pair it with.
Where Is the Institute for Nature Study? Getting to Know This Forest in Central Shirokanedai
The Institute for Nature Study’s address is 5-21-5 Shirokanedai, Minato Ward, Tokyo, and the nearest stations are Shirokanedai Station on the Tokyo Metro Namboku Line and Toei Mita Line, and Meguro Station on the JR Yamanote Line and Tokyu Meguro Line.
Its official name is the Institute for Nature Study, National Museum of Nature and Science; it is managed by the National Museum of Nature and Science in Ueno and is positioned as a research-oriented green space where people can observe nature and learn about ecology in the heart of the city.
The grounds have deciduous trees such as sawtooth oak, zelkova and giant dogwood, evergreens such as chinquapin, oaks and pines, plus grassland of silver grass and reeds, ponds and streams, and the Institute for Nature Study’s introduction page describes it as an oasis in the centre of a great city.
Most of the plants in the grounds have name tags and information boards, so as you walk you can get to know many trees you normally could not name, which makes it very friendly for adults and children who enjoy observing nature.
From a Muromachi-Era Clan Residence to the Shirokane Imperial Estate
The history of this land is longer than you might think: pottery and shell mounds from the Middle Jomon period have been excavated in the grounds, showing that people lived here a very long time ago.
In the Muromachi period a local clan built a residence here, and the remains of the earthworks from that time can still be seen in the grounds today.
In the Edo period, in Kanbun 4 (1664), this became the secondary residence of Matsudaira Sanuki-no-kami Yorishige, lord of the Takamatsu domain, and the “Monogatari no Matsu” and “Orochi no Matsu” in the grounds are thought to be old pines left from the garden of that time.
In the Meiji era the site became a gunpowder store managed by the Navy Ministry and the Army Ministry, and in Taisho 6 (1917) it came under the Imperial Household Ministry (the body at the time was the Imperial Forest Management Bureau, renamed the Imperial Forestry Bureau in 1924) and became known as the Shirokane Imperial Estate.
On 12 April 1949 the land was designated a national Natural Monument and Historic Site under the name “Former Shirokane Imperial Estate”, after which it opened to the public as the National Institute for Nature Study, and since 1962 it has been the Institute for Nature Study attached to the National Museum of Nature and Science.
Why the Autumn Leaves Here Are Different
Because protecting nature has been the priority for many years, most of the trees at the Institute for Nature Study keep their natural shape, and fallen old trees are often left as they are, letting you see the real cycle of a forest.
This also means there are no neatly pruned rows of maples here; the autumn colour is scattered in clumps through the woods, and you have to look for it as you walk before you turn a corner and come upon a particularly bright patch of red.
People who love refined pond gardens such as Rikugien and Koishikawa Korakuen will find a completely different autumn here, with the plain colours of something close to the mixed woodland of Musashino.
When Are the Autumn Leaves at the Institute for Nature Study at Their Best? Timing Your 2026 Visit
Looking first at the usual-year data, the sources point in much the same direction: the Institute for Nature Study is one of the later places in Tokyo to change colour.
The Japan Weather Association’s tenki.jp autumn-leaf page for the Institute for Nature Study gives the usual peak as late November to mid-December, with Japanese maple and soapberry (mukuroji) as the main species.
The Institute for Nature Study’s own monthly highlights are also useful: the wax trees turn red from about early November to early December, the shiromoji (Lindera triloba) turns yellow from about mid- to late November, the witch hazel (mansaku) turns yellow from about late November to early December, and the Japanese maples turn red from late November to late December.
Putting these together, the autumn-leaf window at the Institute for Nature Study is roughly late November to mid-December, and the best time is early December, when you are most likely to see the red of the Japanese maples and the yellow leaves at the same time.
The 2026 Forecast
The Japan Weather Association’s 2026 autumn-leaf forecast, published on 1 October 2026, says that this year the peak across the country will generally be around the usual time or later than usual.
In eastern Japan, which includes Kanto-Koshin, temperatures have stayed high since the second half of September and are expected to remain above normal through November, so the peak at most autumn-leaf spots will be around the usual time or slightly later.
The 2026 forecast on the tenki.jp page is early to mid-December, which overlaps the second half of the usual range and fits the overall view of “around the usual time or slightly later”.
The Japan Weather Association also explains that tenki.jp will update the forecast three or four times up to November, so the safest thing is to check the latest forecast and current status once more a week before you set off.
Choose Your Timing by the Colours You Want to See
If you like the early-season mix of red, yellow and green, aim for late November, when the wax trees have already turned red and the Japanese maples are still slowly changing colour.
If you want to see Japanese maples that are red all over, early to mid-December is more reliable, and the light in the woods also becomes brighter as the leaves fall.
From mid-December the autumn leaves gradually fall and are replaced by red berries such as iigiri (Idesia), manryo and senryo, so people who enjoy observing plants can still find plenty to enjoy.
Must-See Autumn-Leaf Spots: Highlights on a Loop of the Paths
The entrance to the Institute for Nature Study is at the Education and Administration Building; after buying your ticket, follow the path inwards and the main observation areas appear one after another.
You can pick up a map of the grounds at the entrance, and the grounds map and highlights page also introduces each spot, so looking at it before you go in makes it easier to find your way.
Roadside Botanical Garden: Autumn Colour Right Inside the Gate
The Roadside Botanical Garden, just inside the entrance, is an area where you can see plants in every season, and in autumn the wax trees, witch hazel and Japanese maples are the first to show their colours here.
The paths in this area are fairly level, so people with older relatives or pushchairs can take their time here first before deciding whether to go deeper into the forest.
Monogatari no Matsu and Hyotan Pond
Further in you will see the Monogatari no Matsu, an old pine thought to date from the days of Matsudaira Sanuki-no-kami’s secondary residence, and the nearby gourd-shaped “Hyotan Pond” is also thought to have been part of the stroll garden of that time.
In autumn the water reflects the colours of the surrounding trees, making this one of the few corners of the grounds with a hint of a garden atmosphere.
Aquatic Botanical Garden and Mori no Komichi
The Aquatic Botanical Garden is one of the more open spots in the grounds, where the waterside plants set off the surrounding autumn leaves, and it is also one of the places to observe Japanese maples and wax trees.
In fiscal 2025 the Aquatic Botanical Garden pond underwent its first “kaibori” in about 20 years (a traditional clean-up in which the pond is drained and the bed left to dry), and the pond has now been refilled and its ecosystem is slowly recovering.
The Mori no Komichi is a path that runs along the wetland under zelkova and giant dogwood trees, and in autumn the canopy overhead turns from green to yellow, and it is very quiet.
Orochi no Matsu, Mizutori no Numa and the Residence Site
The Orochi no Matsu is a large pine about 300 years old that fell in a typhoon in Reiwa 1 (2019), and the Institute chose to leave it as it fell so that visitors can see the natural form of the tree.
Spot-billed ducks and herons often visit Mizutori no Numa (the Waterbird Marsh), and in autumn and winter, once the leaves have fallen, the birds by the water are actually easier to see.
Near the residence site, U-shaped earthworks are preserved that are thought to be the remains of a medieval clan residence, and coming here lets you sense the layers of history in this land.
Musashino Botanical Garden: Home of the Yellow Leaves
The Musashino Botanical Garden area is planted with many plants common in the Musashino region, and the shiromoji turns bright yellow from mid- to late November.
You can also see red Japanese maples here, so it is a good place to linger if you want to photograph a red and yellow contrast.
Tips for Photographing and Observing the Autumn Leaves
The woods at the Institute for Nature Study are fairly dense, and around midday, when the sunlight filters through gaps in the canopy, the glow of backlit autumn leaves is at its most striking.
On cloudy days the light in the woods is rather dim, but the colours are actually more saturated, so you can focus on close-up details of the leaves and the ground carpeted with fallen leaves.
The paths in the grounds are narrow, so please remember to leave room for others when taking photos, and do not use a tripod that blocks other visitors.
If you want to learn more about the trees in front of you, compare them with the name tags and memorise the leaf shapes of the Japanese maple, wax tree, shiromoji and witch hazel, so that you can recognise them at a glance elsewhere next time.
After the leaves fall in autumn and winter, birds are easier to spot, so bring a small pair of binoculars and you may well see plenty of waterbirds around Mizutori no Numa.
Opening Hours, Fees and Rules
The Institute for Nature Study is not a park open all day, and its opening hours, closing days and fees differ from those of ordinary metropolitan parks, so be sure to check before you set off.
| Item | Details |
|---|---|
| Opening hours (1 September to 30 April) | 9:00 to 16:30, last entry 16:00 |

The information above comes from the Institute for Nature Study visitor information; the grounds sometimes open on closing days as well, so go by the official opening calendar.
Dates to Watch in Autumn 2026
In 2026, Culture Day on 3 November falls on a Tuesday, and under the rules entry is free that day; the next day, 4 November, is the day after a national holiday, so the grounds are in principle closed.
Labour Thanksgiving Day on 23 November is a Monday, so under the rules the grounds are open that day and closed on Tuesday 24 November.
During the peak autumn-leaf season in early to mid-December, Monday is the regular closing day, so when planning it is best to put the Institute for Nature Study on a Tuesday to Sunday and check the opening calendar again before you set off.
Rules
In the grounds, collecting plants or animals, drinking alcohol, smoking, littering, entering fenced areas, and activities such as jogging, exercise and group singing are prohibited.
You also cannot bring in pets, play equipment such as balls or skipping ropes, insect nets and cages, alcohol or musical instruments, and please take your rubbish home with you.
These rules are all there to protect the ecosystem of the grounds, so when taking photos please do not step into fenced areas or onto the grass for a better angle.
Path Conditions and Accessibility
The paths in the grounds are not paved, some sections have steps, and the ground can be slippery after rain, so wear comfortable walking shoes.
Three wheelchairs are available free of charge at the entrance; they cannot be reserved and can be used whenever one is free, so if you are visiting with older relatives, ask at the reception counter.
Access: Getting There from Shirokanedai and Meguro Stations
The Institute for Nature Study has no general car park, so the most convenient way is to take the train to Shirokanedai or Meguro Station and walk along Meguro-dori.
By Tokyo Metro Namboku Line or Toei Mita Line
Leave Shirokanedai Station by Exit 1 and walk along Meguro-dori for about 7 minutes to reach the entrance; this is the nearest route.
The Namboku Line runs direct to Shirokanedai from stations such as Tameike-Sanno and Yotsuya, and the Mita Line runs direct from the Otemachi and Hibiya area, which is very convenient if you are staying in these areas.
By JR Yamanote Line or Tokyu Meguro Line
From the East Exit of JR Meguro Station it is about a 9-minute walk along Meguro-dori, and from the Tokyu Meguro Line, leave Meguro Station by the Main (Central) Exit for a walk of about 9 minutes as well.
The Yamanote Line makes it easy to get to Meguro Station from Shinjuku or Shibuya, and access information is summarised on the Institute for Nature Study access page.
By Car or Private Charter
The Institute for Nature Study has no car park for general visitors, so if you drive you will need to find a coin car park nearby yourself, and spaces are not always easy to find at weekends.
With a private charter or transfer, passengers can be dropped off and picked up along Meguro-dori while the driver arranges a separate place to wait, so there is less to worry about with parking.
How Long to Stay and Suggested Itinerary
The main loop of paths at the Institute for Nature Study is not especially long, but because the paths are dirt and you will often stop to look at the plants, allow 1 to 1.5 hours.
For people who enjoy photography or reading the plant name tags carefully, spending 2 hours would not be unusual; remember that there is no entry after 16:00.
| Time | Suggested plan |
|---|---|
| Morning | Enter the Institute for Nature Study when it opens at 9:00 and walk the Roadside Botanical Garden, Aquatic Botanical Garden and Mori no Komichi while it is quiet |
| Midday | Have lunch around Shirokanedai or Meguro; there are plenty of cafes and restaurants along Meguro-dori in Shirokanedai |
| Afternoon | Move on to other autumn-leaf spots in central Tokyo, such as Rikugien, Koishikawa Korakuen or the Meiji Jingu Gaien ginkgo avenue |
| Evening | If you choose a garden with an evening illumination, you can leave the illumination until last |
Nearby Spots to Combine
Right next to the Institute for Nature Study is the Tokyo Metropolitan Teien Art Museum, and in autumn you can fit both into the same morning, but check the museum’s exhibitions and opening days separately.
Rinshi no Mori Park, also in the Meguro area, can be linked in too, which suits people who want to walk more of the Jonan (south Tokyo) area.
To see plenty of Tokyo’s autumn leaves in one go, see our Rikugien Autumn Leaves Guide, Koishikawa Korakuen Autumn Leaves Guide and Meiji Jingu Gaien Ginkgo Avenue Guide; the peak times at all three are close to those at the Institute for Nature Study.
Planning for Older Relatives and Children
The paths at the Institute for Nature Study are unpaved and some places have steps, so with older relatives you can just walk the Roadside Botanical Garden and Aquatic Botanical Garden near the entrance rather than pushing to complete the whole loop.
Children who come here are easily drawn to the creatures in the ponds and the fallen leaves, but catching insects and taking plants are prohibited in the grounds, so agreeing the rules with your children before you set off makes things go more smoothly.
The Education and Administration Building at the entrance has an exhibition hall, a shop and a rest area, so if you get tired you can come back here to sit for a while, and you can also buy plant-themed postcards and books.
FAQ
Q1: When are the autumn leaves at the Institute for Nature Study at their best?
In a usual year the peak is roughly late November to mid-December, and the best time is early December.
For 2026 the Japan Weather Association forecasts that the peak in eastern Japan will be around the usual time or slightly later, so check the latest forecast on tenki.jp again before you set off.
Q2: Can I visit the Institute for Nature Study on a Monday?
It is in principle closed every Monday, but when that is a national holiday it opens and closes on the following Tuesday instead.
Monday 23 November 2026 is Labour Thanksgiving Day, so it is open that day and closed the next day, 24 November.
Q3: Can I pay the entrance fee by card?
The entrance fee for adults and university students is 320 yen and, as of October 2026, is cash only, so remember to bring change.
High school students and younger and people aged 65 and over enter free, and need to show ID proving their age.
Q4: Is there an evening illumination at the Institute for Nature Study?
The Institute for Nature Study is a research-oriented green space whose purpose is to protect nature; the evening viewing and events fields on the tenki.jp page both say “no information”, and entry is only until 16:00.
If you want to see illuminated autumn leaves, you can schedule another garden in central Tokyo with an illumination for the evening.
Q5: Can I have a picnic or bring a pet?
Drinking alcohol, exercise and pets are prohibited in the grounds, and you must take your rubbish home, so it is better suited to quiet walks and observing plants.
If you want a picnic or a place for children to run around, plan a separate visit to a park with a large lawn.
Final Thoughts: A Quiet Tokyo Autumn in the Forest of Shirokanedai
The autumn leaves at the Institute for Nature Study are not a large, neat tunnel of maples but colours scattered through the forest that you only see if you walk slowly.
When planning, remember three things: the peak is roughly late November to mid-December (best in early December), the grounds are in principle closed on Mondays and on the day after a national holiday, and the entrance fee is cash only, with no entry after 16:00.
With these points sorted, the Institute for Nature Study makes a lovely quiet morning of autumn-leaf viewing in central Tokyo, before you move on to other gardens for more spectacular colours.
