Two Indoor Playgrounds
1. Aeon Mall outside the East Gate (also called the Diamond City Mall) Pricey but really fun, this indoor playground is called Børnelund. It features a jumpy raceway, jungle gym with slides descending into a field of plastic balls, a large […]

2. Aeon Mall out the Fussa Gate (Hinode) : Yu Kids Island is less expensive, a bit smaller, but tons of fun all the same. This indoor playground is about 6km from Fussa Gate. It features many large movable objects – things that rotate around or rock back and forth that kids can climb up or hang from. There are two balloon stations where kids can hit at balloons being blown around. This place is the right size to be able to stay in one place and watch your kids play. I went with kids ages 18 months to 41/2 years and they all had a great time. Costs a flat ¥600 per child for unlimited play during the week and 60 minutes of play on the weekend. Note, with the unlimited weekday play you cannot come and go. It is unlimited play until you leave. It is located on the third floor near the food court with a great kid-size bathroom right next to it. Open 10am but starts opening early during the Christmas season when the mall opens earlier. Phone for Hinode Aeon: 042-588-8000. GPS: 35.73349, 139.27547.
DIRECTIONS: Go straight out Fussa Gate. Cross one set of tracks and stay right at the “Y” split. After you pass over the second set of tracks (with the Fussa train station on your right), make an immediate right where you must (or you will drive the wrong way into a one-way street.) Then take the next left onto the main street. The train station is now behind you and this street becomes Route 165. Follow route 165 over the Tama river, and keep going straight. You will see fuschia Aeon Mall signs directing you. One warns when you have 3km to go. And the next, just after the entry to the expressway, will be on the right, telling you to turn left. Drive a few blocks and you will see the mall at your 2’o’clock position. – Sarah Straus, 2012
