Welcome to Kofun Park
Hello there!
This is Asukarando, your friendly SaruKuma writer.
Today’s destination is
Iwabaru, Kaou-machi, Yamaga City, Kumamoto Prefecture,
the wonderful “Kofun Park”.
Welcome to Kofun Park, where ancient burial mounds and historical buildings come together! \(^o^)/
There’s a small parking area for several cars right below the park.
Below that, there’s an even larger parking lot, complete with spacious restrooms (^з^)-☆
The closest restrooms to Kofun Park itself are at the neighboring Kaou Bussankan (a local produce market and restaurant) (^-^)
There are even charming stone tables and chairs scattered around the park (^з^)
A covered rest area is also available (^-^)v
Since it’s right next to the playground, parents can sit back, relax, and watch the kids play to their hearts’ content (*^^*)
Top Highlights of Kofun Park
And here’s the star of the show — the Kofun Park playground! (⌒0⌒)/~~
Two side-by-side roller slides come tumbling down from the top of the hill (^з^)-☆
Here’s the view from above (^-^)/
The playground equipment has a wonderfully nostalgic feel, but everything is still safe and a blast to ride! ☆
There’s another slide over here, too (^-^)v
Kids can climb up from any direction!!
So exciting! (⌒0⌒)/~~
Check out this slide, too (^з^)-☆ It might take a little courage on your first try! (^з^)-☆
There’s a smaller slide perfect for little ones, too (^-^)v
And here’s a special Kofun Park feature — a traditional takayuka-shiki (raised-floor) house, just like the ones you’d see in a Japanese history textbook!
Visitors can actually go inside (^o^)/ It feels just like a secret hideout — kids will absolutely love it! Just be aware the stairs are a bit steep, so keep an eye on smaller children (^^)
And here’s the breathtaking view from the highest point in the park (*^^*)
With a wide grassy field too, why not stop by Kofun Park — the park where ancient Japan comes to life — for a memorable day out? (⌒0⌒)/~~
