South of Kyoto Station and north of central Nara, on the hills between the two, there is a prefectural park themed on the Japanese satoyama landscape: this is Keihanna Commemorative Park (Keihanna Kinen Koen).
The park’s official name is a long one, “Kyoto Prefectural Kansai Science City Commemorative Park”; it is in the town of Seika in Soraku District, Kyoto Prefecture, and was created to commemorate the building of Kansai Science City (Keihanna).
In autumn the main attraction is Suikeien, the Japanese garden in the paid area, where the maples of Momiji Valley are set off by small waterfalls and ponds, and when you look down from the elevated Kangetsu Bridge, the autumn colour of the whole garden spreads out before you at once.
On the nights of the autumn-leaf light-up, the waterfalls in Suikeien are stopped and the pond becomes a “water mirror” that reflects the red maples, the most iconic autumn image of Keihanna Commemorative Park.
The questions people ask most when planning are: when are the autumn leaves at Keihanna Commemorative Park at their best? Which days is the 2026 night light-up held, and what time does it start? And how do you get there from Kyoto or Nara without a car?
This article draws on information published by the park management, the Japan Weather Association’s tenki.jp and the autumn-leaf information site Walkerplus to explain the autumn-leaf season, the must-see spots, the light-up schedule, admission, access and itineraries, all in one place.
Where is Keihanna Commemorative Park? Getting to know the satoyama park in Seika
Keihanna Commemorative Park is at 6-1 Seikadai, Seika, Soraku District, Kyoto Prefecture, in the south of Kyoto Prefecture on the Keihanna Hills, roughly between central Kyoto and central Nara.
According to the overview published by the park, it opened in April 1995 and covers 24.1 hectares, preserving a satoyama environment of 15.1 hectares.
The park was also developed as part of the project marking the 1,200th anniversary of the founding of Heian-kyo, so the whole park is themed on landscapes that express Japanese culture and climate.
The park is divided into a free area and a paid area, and the two feel very different, so when planning your autumn-leaf visit it is best to be clear first which one you are going to.
The free area: the lawn, the valley and the visitor centre
The free area has a large lawn where you can roam freely, with play equipment for children and a stream to paddle in, and in spring about 300 cherry trees bloom here.
The valley (Taniai) is an area that expresses a quiet satoyama, with a small river, a bamboo grove and a plum grove, and as you walk through it you can hear the rustle of bamboo leaves and the sound of flowing water.
The visitor centre introduces how the park came about, its natural environment and event information, and you can also use it as a place to rest.
The paid area: Suikeien and Mebuki no Mori
The real autumn-leaf highlights are in the paid area: Suikeien, a modern Japanese stroll garden, and Mebuki no Mori, the satoyama woodland around Nagatani Pond.
Suikeien is characterised by the way you can enjoy a space where nature and human design are interwoven from different distances and angles, and it is a public garden where adults and children alike can stroll at ease.
A loop of Mebuki no Mori is about 1.2 km and takes about 30 minutes on foot; there are azaleas in spring, and in autumn you can see the woodland change colour.
The park is currently run by the Kyoto landscape gardening company Ueyakato Landscape as the designated manager, which is responsible for garden maintenance and event planning in the park.
When are the autumn leaves at Keihanna Commemorative Park at their best? Pinning down the 2026 season
Looking first at the usual timing, the sources differ slightly, but they all fall within November.
The Japan Weather Association’s tenki.jp page for Keihanna Commemorative Park gives the usual peak as mid- to late November, and the 2026 peak forecast as late November to early December.
The autumn-leaf information site Walkerplus page for Keihanna Commemorative Park says the leaves usually start to turn from late October to early November, with the usual peak from early to late November.
The Japan Weather Association’s autumn-leaf peak forecast published on 1 October 2026 says that temperatures from western Japan will stay above average until November, and the peak in the Kinki region will mostly be around average or later than average.
The Japan Weather Association also explains that it will update the forecast on tenki.jp three to four times up to November, so you can check the latest forecast period again before you set off.
Putting all this together, the autumn-leaf window at Keihanna Commemorative Park is roughly mid-November to early December, and the time we recommend most is late November.
Late November also happens to cover the last two weekends of the autumn-leaf light-up, so you can see Momiji Valley by day and the water-mirror reflections by night, fitting both kinds of scenery into one trip.
The park updates the colour status of the maples in Suikeien on the “Momiji no Irozuki Joho” (maple colour information) page of its official website, and also posts “the park now” photos on its social media accounts, so it is safest to check the latest status before you set off.
Order of colouring: Suikei-dana first, then Momiji Valley
The colour information published by the park says the area around Suikei-dana turns earlier, while Momiji Valley can be viewed from Kangetsu Bridge, where you can watch the colour spreading down towards the valley floor.
If your dates fall in mid-November, you can focus on Suikei-dana and the area around Kangetsuro; if it is late November, there is a better chance of Momiji Valley having turned red all over.
| Source | Usual peak | 2026 information |
|---|---|---|
| Japan Weather Association tenki.jp | Mid- to late November | Peak forecast late November to early December |
| Walkerplus | Early to late November | Leaves usually start to turn late October to early November |
| Our recommendation | Mid-November to early December | Late November recommended most |
Must-see autumn-leaf spots at Keihanna Commemorative Park: Momiji Valley, Kangetsu Bridge and Suikei-dana
The main sights of Suikeien are clearly explained on the park’s English-language Suikeien page, and they are set out below in the order you would walk them.
Momiji Valley: a garden of maples and small waterfalls
Momiji Valley is the main autumn-leaf area of Suikeien; the maples are carefully arranged with several small waterfalls among them, and in autumn the red leaves and the sound of water combine into a garden scene with real depth.
The autumn-leaf species listed by tenki.jp are Japanese maple (iroha momiji), mountain maple (yama momiji) and large-leaf maple (o momiji), and Walkerplus also lists species such as maples, konara oak and cherry.
Walking through Momiji Valley, you can see the maple leaves together with mossy rocks and streams close up, which feels completely different from looking down from the bridge, so we suggest trying both viewpoints, from above and below.
Kangetsu Bridge: looking down on the garden from a lattice bridge ten metres up
Kangetsu Bridge is an elevated lattice bridge, 123 m long and 4 m wide, with its deck more than 10 m above the water, and it is the best viewpoint over the whole of Suikeien.
Looking down from the bridge, you can fit Momiji Valley, the pond and the distant woodland into one frame, and this is the composition that appears most often in photos of the autumn leaves at Suikeien.
Kangetsu Bridge has a very modern design, unlike the wooden or stone bridges of traditional Japanese gardens, and the contrast between its steel lattice and the autumn leaves is a key feature of this “modern stroll garden”.
Suikei-dana: stepped water features like rice terraces
Suikei-dana is a water feature that links Nagatani Pond with the pond below through tier upon tier of water basins, shaped like rice terraces, with stepping stones you can walk across the water on.
In autumn the maples around Suikei-dana change colour earlier, and the red leaves are reflected in the basins, making it a good place to take photos at a leisurely pace.
Iwagumi and Kangetsuro
Suikeien also has an “iwagumi” (rock arrangement) made up of about 500 granite blocks from Inujima in Okayama Prefecture, about 6 to 7 m high, with most of the stones weighing between 20 and 40 tonnes.
These huge rocks give the garden a weighty presence that contrasts with the delicacy of Momiji Valley.
Kangetsuro is at the centre of Suikeien and houses a rest area, an observation deck, a training room, “Gallery Tsuki no Niwa” and the Sagara Momen (Sagara cotton) heritage hall, so you can go in and sit down when you are tired.
Mebuki no Mori and the arbour in the bamboo grove
If you have enough time, you can do a loop of Mebuki no Mori, following Nagatani Pond into the satoyama woodland to enjoy natural autumn colour that is different from the garden.
Nagatani Pond is known locally by the nickname “Nagatan”, and the pond and surrounding satoyama woodland are a wildlife sanctuary where you can see waterbirds in winter.
Suikeien also has a thatched arbour surrounded by a bamboo grove, a quiet little corner in the autumn-leaf season.
2026 Keihanna Commemorative Park autumn-leaf light-up: dates, times and water-mirror reflections
The 2026 autumn-leaf light-up has been announced: it runs from 3 November to 29 November, but only on Fridays, Saturdays, Sundays and public holidays.
The light-up runs from sunset to 21:00 with last entry at 20:30, the venue is Suikeien, it goes ahead in the rain and no advance booking is needed.
The fee is simply the garden admission fee, and admission is free on 3 November and 15 November, so if you want to save on tickets you can plan your visit for one of these two days.
On light-up days the car park can be used until 21:30, so drivers do not need to worry about being unable to get out of the car park after the light-up.
2026 light-up dates at a glance
Based on the 2026 calendar, the light-up days that meet the “Fridays, Saturdays, Sundays and public holidays” condition are listed below; please check the park’s latest announcements for the actual dates.

Events held alongside the light-up
On 15 November (Sun) there is a “Hoshizora Cafe” (starry sky cafe) held together with the autumn-leaf light-up, and on 21 November (Sat) there is “Momiji Light-Up x Nihon no Geino” (Japanese performing arts).
On 22 November (Sun), 23 November (Mon, public holiday), 28 November (Sat) and 29 November (Sun) there are also “Momiji Light-Up Tours”, so if you would like a guided tour you might prioritise these days.
For details of the events and whether booking is needed, please check the latest information on the light-up page before you set off.
How to see the water-mirror reflections
The highlight of the light-up is the waterfalls stopped for the night and the still pond surface: the water becomes as calm as a mirror and reflects the illuminated autumn leaves perfectly.
For clear reflections, it is best to choose a windless night and find a spot by the pond where you can see both the real scene and its reflection at once.
Kangetsu Bridge is also a great viewpoint at night, letting you look down on the illuminated Momiji Valley from above, which feels different again from the daytime view.

Parking
The park car park is on the west side and holds 200 ordinary cars and 10 large vehicles; it costs 500 yen per visit for ordinary cars and 1,700 yen per visit for large vehicles.
The car park is open from 8:30 to 17:30, extended when the park opens at night, and on light-up days it can be used until 21:30.
The car park payment machine takes cash only, and does not accept 5,000-yen or 10,000-yen notes, so remember to have 1,000-yen notes or coins ready.
The park also specifically asks visitors not to park at nearby commercial facilities and to use the park car park.
Food and rest
There is no permanent shop or restaurant in the park, and “Mori no Cafe Nagatan”, featured on the park’s food and drink page, mainly opens on Sunday and some public holiday afternoons.
The cafe is on the ground floor of Kangetsuro and opens from 12:00 to 16:30 (last orders 16:00); its opening days in November 2026 are the 1st, 3rd, 8th, 15th, 22nd and 29th.
At weekends in spring and autumn, food trucks occasionally set up on the lawn or in front of Suikeien, but not at fixed times, so if you want to eat in the park it is best to bring some simple food with you.
How to get to Keihanna Commemorative Park: train, bus and car
The park’s access page lists two options, train plus bus or driving; the nearest stations are Hosono Station on the JR Gakkentoshi Line and Shin-Hosono Station on the Kintetsu Kyoto Line.
Train + bus: from Hosono or Shin-Hosono Station
JR Hosono Station and Kintetsu Shin-Hosono Station are right next to each other; from in front of the station take a Nara Kotsu bus on route 56 bound for “Gakken-Nara-Tomigaoka Station”, and you will reach the park in about 9 minutes.
If you are going to Suikeien, get off at “Koen Higashi-dori”; if you are going to the lawn, get off at “Keihanna Kinen Koen”.
If you are starting from Gakken-Nara-Tomigaoka Station on the Kintetsu Keihanna Line, you can take a Nara Kotsu bus on route 56 towards Hosono Station, which takes about 18 minutes.
From central Kyoto, you can take the Kintetsu Kyoto Line from Kintetsu Kyoto Station to Shin-Hosono Station and change to the bus.
From Osaka, you can take the JR Gakkentoshi Line to Hosono Station, or the Kintetsu Keihanna Line, which runs through from the Osaka Metro Chuo Line, to Gakken-Nara-Tomigaoka Station.
Driving: Seika-Gakken Interchange on the Keinawa Expressway
If you are driving, leave the Keinawa Expressway at Seika-Gakken Interchange and follow Seika-odori west for about 1 km.
If you are on National Route 163, turn north at the Inuidani-nishi junction for about 2 km, then follow Seika-odori east for 300 m.
If you are on the Yawata-Kizu prefectural road, head west for about 2.2 km from the junction with Seika-odori.
Getting back after the night light-up
The light-up ends at 21:00, and Nara Kotsu buses still run towards Hosono Station in the evening, but weekend and weekday timetables differ, so check the timetable linked from the park’s access page before heading back.
When you take older relatives or children to the light-up, waiting at a bus stop and changing trains at night can be tiring, and arranging a private charter or transfer makes things much easier.
Suggested time and itinerary for Keihanna Commemorative Park
If you only visit Suikeien, the author suggests allowing 1.5 to 2 hours so that you can take your time over Momiji Valley, Kangetsu Bridge and Suikei-dana.
If you also want to do a loop of Mebuki no Mori, add another 30 minutes to an hour, including time for photos and rests.
| Time | Suggested plan |
|---|---|
| Morning | Visit other autumn-leaf spots in southern Kyoto or Nara |
| 14:00 to 16:30 | Enter Suikeien to see Momiji Valley, Suikei-dana and Kangetsu Bridge (enter before 16:30) |
| 16:30 to sunset | Rest in the free area or in the car while waiting for the light-up (whether you need to re-enter between the day and evening sessions depends on that day’s announcement) |
| Sunset to 20:30 | On light-up days, enter Suikeien to see the water-mirror reflections (enter before 20:30) |
| After 21:00 | Take the bus back to Hosono Station, or go straight back to your hotel by private charter |
The table above is for light-up days; on other days we suggest visiting Suikeien from midday into the afternoon so you are not shut out after 4:30 pm.
Nearby autumn-leaf spots to combine
East of Soraku District, where Keihanna Commemorative Park is located, is Mt Kasagi, famous for its cliff-carved Buddhas; see our Mt Kasagi Autumn Leaves Guide, Kyoto.
To the north you can link up with the temple autumn leaves of Uji, for example in our Mimurotoji Temple Autumn Leaves Guide, Uji, and to the south is central Nara with our Nara Park Autumn Leaves Guide.
All three directions are within range for a day trip, but train connections between them are patchy, so driving or a private charter makes them easier to arrange.
Keihanna Commemorative Park autumn leaves FAQ
Q1: When are the autumn leaves at Keihanna Commemorative Park at their best?
The usual peak is around mid- to late November, and tenki.jp’s 2026 peak forecast is late November to early December; taking everything into account, we recommend late November most.
Q2: Which days is the 2026 autumn-leaf light-up held?
The 2026 autumn-leaf light-up is held on Fridays, Saturdays, Sundays and public holidays from 3 November to 29 November, from sunset to 21:00, with last entry at 20:30.
Q3: Do I need a separate ticket for the light-up?
No separate light-up ticket is needed; you just pay the Suikeien admission fee, and on 3 November and 15 November admission is free.
Q4: Is there anywhere to eat in the park?
There is no permanent restaurant or shop in the park; the cafe in Kangetsuro opens on Sunday and some public holiday afternoons and food trucks sometimes come at weekends, so we suggest bringing a light snack or eating near the station beforehand.
Q5: Is it easy to visit with older relatives or a pushchair?
The park has barrier-free design on its main paths and in its buildings, there are lifts in the buildings, and wheelchairs can also be borrowed.
However, there are still slopes, changes in level and narrow spots in the park, so please take it slowly on Kangetsu Bridge and in Momiji Valley.
Final thoughts: between Kyoto and Nara, save an evening for the water-mirror autumn leaves of Suikeien
What makes Keihanna Commemorative Park special is the way it brings together the modern design of Kangetsu Bridge and a traditional autumn-leaf garden, so you can see a different autumn by day and by night.
When planning, remember three things: late November is the best time to go, the light-up is only on Fridays, Saturdays, Sundays and public holidays from 3 to 29 November, and the car park takes cash only.
With these points sorted, Keihanna Commemorative Park fits nicely between southern Kyoto and Nara as a quiet and distinctive evening stroll on your autumn trip.
