If you’re new to Japan and looking for an affordable place to take your children, finding a good day-trip destination can feel overwhelming.
But here in Kanagawa, there’s a wonderful, inexpensive spot that many visitors don’t know about: the Isehara Children’s Science Museum and its planetarium.
It’s fun, educational, and very affordable.
And the best part?
It’s within walking distance of Isehara Station, and there’s also a bus if you prefer not to walk.
Where It Is & How to Get There
The Isehara City Children’s Science Museum is located in Isehara City along the Odakyu Line.
If you live nearby or anywhere along the line, it’s an easy and inexpensive place to visit.
It’s about a 15‑minute walk from Isehara Station.
The route is generally calm and easy to follow, but there are a few gentle slopes and several crossings, so if you have small children or a stroller, it might feel a bit long.
In that case, you can also take a bus.
Walking from the station (about 15 minutes)
Exit from North Exit (北口) and walk toward the Isehara City Hall.
The streets are generally calm and easy to walk with children.
Along the way you’ll see small cafés, flowers planted along the sidewalks, and — on a clear day — a beautiful view of Mount Ōyama.
When you reach the City Hall area, you’ll see a blue building next to it. That’s the library and the science museum.
Access by Bus
From Isehara Station North Exit
- Take the bus（Route 伊74) from Track 2
- Route: For Aikoishida Station (via Tanaka/Tokai University Hospital)
- Get off at “North Entrance of City Office” (Isehara Shiyakusho Kitaguchi)
From Isehara Station South Exit
- Take the bus（Route 伊06) from Track 4
- Route: For Tokai University Hospital
- Get off at “In front of Administration Center” (Gyōsei Center-mae)
It’s a two‑minute walk from these bus stops to the Isehara Children’s Science Museum.
Buses run infrequently, so be sure to check the timetable before you go.
A Full Day of Fun from Just ¥100 for Children
At the entrance, you’ll find a ticket machine.
You can buy:
- Science museum only
- Planetarium only
- Or both
Elementary and middle school students can enter for 100 yen.
The planetarium requires an additional 200 yen, but it’s optional.
Inside the Science Museum
The museum has two floors of hands-on exhibits. Kids can push buttons, move levers, and try small science experiments.
It’s lively but friendly — children from toddlers to older elementary students all play together.
Your ticket allows free re-entry on the same day, so you can leave for lunch and come back.
Even if you don’t speak much Japanese, many of the exhibits are hands-on, so children can learn by touching, trying, and experimenting.
The Planetarium Experience
The planetarium room is large, with over 100 seats.
Front seats recline; back seats don’t, but the dome is easy to see from anywhere.
Before the main show, a staff member explains the night sky for that day — how to find constellations, how to spot the Big Dipper, and what stars are visible in the current season.
Even if your Japanese is still basic, the visuals make it easy to enjoy.
The Main Planetarium Program
The program changes regularly.
During a recent visit, the main program was a planetarium adaptation of Night on the Galactic Railroad (銀河鉄道の夜), a famous Japanese story.
The animation filled the entire dome — beautiful, dreamy, and surprisingly realistic.
If you get motion sickness easily, be aware that the immersive visuals can feel intense.
But for most people, it’s a magical experience.
The planetarium program changes every few weeks or months, so the show you see may be different from the one described in this article.
Check the official schedule before you visit.
