Stand on the long staircase at Honmyo-ji Temple, where old candle stands line the steps, and the castle keep rises over the city below. On a clear day Mt. Aso sits behind it. That pairing — a hilltop view and a castle — is the shape of a good day in Kumamoto.
The city suits travellers who like castles, gardens and hills more than nightlife, and who are happy to use trams, buses and their own legs. Spring brings cherry blossoms to the castle grounds; the last weekend in March brings the Nighttime Cherry Blossom Festival at Honmyo-ji.
This guide covers the sights worth your time, with practical notes on how to combine them, followed by a one-day plan and answers to common questions.
Top things to do in Kumamoto
1. Kumamoto Castle
The city's most famous landmark, and one of the most beautiful castles in Japan. The current keep is a concrete reconstruction, but several ancillary wooden buildings from the original castle remain. The grounds took severe damage in the April 2016 earthquakes; the main keep has since re-opened, while other surrounding buildings will take years to rebuild.
Go in cherry blossom season, when the grounds fill with hundreds of blossoms. Admission is ¥800, opening hours are 09:00–17:00 with last admission at 16:30.
2. Suizenji Gardens
A renowned Japanese traditional garden, considered one of the four best in Japan. You walk a course of trees and mini hills covered in grass — one of them representing Mount Fuji — in the middle of the city. Food stalls sit in the immediate vicinity.
Pair it with the Suizenji area, which is also home to Suizenji Municipal Stadium.
3. Honmyo-ji Temple
One of the most famous temples in Kumamoto, built in honor of Kato Kiyomasa, the builder of Kumamoto Castle. A long staircase lined with old candle stands leads up to it; beyond the temple another staircase climbs to a park with a statue of Kato Kiyomasa and a viewpoint over the city, with Mt. Aso in the background on clear days.
Time your visit for the last weekend in March, when the Nighttime Cherry Blossom Festival brings live music and lit-up cherry blossoms and candles all the way to the top of the hill.
4. Hosokawa Gyōbutei
The family home of the Hosokawa Clan, in the north-west of the castle site, and a picturesque place to visit. The building suffered damage in the 2016 Kumamoto Earthquake, so visitors are permitted to walk the perimeter to enjoy the garden during special openings, but the house can no longer be entered.
Combine it with the castle, since it sits within the castle's outer walls.
5. Fujisaki Hachimangu Shrine
The most famous shrine in the city, north of Kamitori and not far from downtown. It is the most crowded shrine in the city every New Year, and crowded for other festivals too — most famously the Decorated Horse Parade held every September.
Pair it with a walk through the Kamitori and Shimotori arcades afterwards.
6. Reigando (Miyamoto Musashi's cave)
The "Spirit Rock Cave" lies to the west of Kumamoto and became a temporary home to Miyamoto Musashi, who from 1643 spent many of his last months here meditating and writing his Book of Five Rings. His tomb is situated close by.
It is accessed easily by bus from Kumamoto City and nearby Tamana.
7. Mt. Kinpō
About 11 km from downtown, with a view over Kumamoto and Nagasaki at the top. The city lights are the draw, and you can see the peaks of Mt. Aso in Kumamoto and Mt. Unzen in Nagasaki. There is a temple on top and a fence full of locks that couples have attached to the observation deck.
There is no ropeway, so you hike or take a car. A bus reaches the area, but you then hike about an hour to the top.
8. Hanaokayama
A hill near Kumamoto Station that looks over downtown and has a great night view, with Mt. Aso towering behind the city on a clear day. There is a temple and a huge shrine gate at the top.
You can go up by car, which most couples do, or hike about 15 minutes to the top. The Peace Pagoda, the first of over 80 built by Nichidatsu Fujii and his followers, was erected atop Mount Hanaoka.
9. Lake Ezu
A lake in the city, useful as a slower counterpoint to the castle and garden circuit.
Treat it as a leg-stretching stop rather than a scheduled sight, and check locally for the best access from where you are staying.
10. Shimotori and Kamitori arcades
The downtown commercial district is centred on these two shopping arcades, which extend for several city blocks. The main department stores are here along with a large number of smaller retailers, restaurants and bars, and many local festivals are held in or near the arcades.
This is the natural place to end an afternoon, since Fujisaki Hachimangu Shrine is north of Kamitori.
11. Kumamoto City Hall
In the heart of downtown at Tetorihoncho. Go to the fourteenth floor for a free view of the castle and the downtown area.
It costs nothing, which makes it a sensible first stop if you want to get your bearings before walking the arcades.
12. Kumamoto Prefectural Traditional Crafts Center
Exhibits the various traditional crafts for which Kumamoto is well-known, and includes a gift shop.
Pair it with the Suizenji area, and use the shop if you want something made locally rather than a castle souvenir.
13. Shiki no Sato Park
A park with its own natural hot springs and animal park.
It sits in the Suizenji area, so it works as an add-on to a garden visit rather than a separate trip.
14. Fujisakidai Baseball Stadium
To the west of Kumamoto Castle, and a good occasion to watch amateur baseball. Entry is free.
Check whether a game is on before you build your day around it, and combine it with the castle since the two are neighbours.
15. Kumamoto Prefectural Museum of Art and Kumamoto Prefectural Theater
The city's cultural venues, useful when the weather turns — Kumamoto has significant precipitation throughout the year, especially in June and July.
Keep them as a wet-day alternative to the hills and gardens rather than a fixed slot in a short trip.
If you only have one day
Morning: Start at Kumamoto Castle when it opens, since last admission is at 16:30 and the grounds reward a slow walk. From there, walk the perimeter of Hosokawa Gyōbutei in the north-west of the castle site, then continue to Fujisakidai Baseball Stadium to the west if a game is on.
Afternoon: Head to Suizenji Gardens and walk the course of trees and mini hills, picking up food from the stalls nearby. Add the Kumamoto Prefectural Traditional Crafts Center and, if you have time and energy, Shiki no Sato Park in the same area.
Evening: Climb to Honmyo-ji Temple for the staircase and the viewpoint over the city, then finish downtown in the Shimotori and Kamitori arcades for restaurants and bars. If you would rather have a night view than a temple, swap in Hanaokayama near Kumamoto Station, which you can reach by car or a short hike.
Frequently asked questions
When is the best time to see cherry blossoms in Kumamoto?
During cherry blossom season, when the castle grounds are filled with hundreds of blossoms. If you are in the city in the last weekend in March, Honmyo-ji Temple holds its Nighttime Cherry Blossom Festival, with live music and lit-up cherry blossoms and candles along the route to the top of the hill.
Is the castle open all day?
No. Kumamoto Castle is open 09:00–17:00, with last admission at 16:30, and admission is ¥800. The main keep has re-opened to the public, but other surrounding buildings damaged in the April 2016 earthquakes will take years to rebuild.
Can I visit Hosokawa Gyōbutei?
Only in a limited way. The building suffered damage in the 2016 Kumamoto Earthquake, so visitors are permitted to walk the perimeter to enjoy the garden during special openings, but the house can no longer be entered.
Do I need a car to reach the viewpoints?
Not necessarily. Hanaokayama can be reached by car, which most couples do, or by hiking about 15 minutes to the top. Mt. Kinpō has no ropeway, so you hike or take a car; a bus reaches the area, but you then hike about an hour to the top. Reigando is accessed easily by bus from Kumamoto City and nearby Tamana.
Decide which hill you want to be standing on at dusk, check the castle hours around it, and the rest of your Kumamoto plan falls into place.
