The Railway Museum in Saitama on a Sunday: Me and many kids and parents. It's a great family place - inexpensive and lots of room to run. Who'd wear out first: My nearly 64-year-old arthritic joints or the children?
You take the New Shuttle from JR Omiya Station. It's a bit of a walk, but not bad. Just stay inside the building. The signs by the door can make it seem like you go outside. Buy a one-way or round-trip ticket at a machine (190 yen or 380). The shuttle is not just for museum-goers, but for locals too.
The museum is the first stop and the ride is only a few minutes long. The entrance to the museum is immediately after you exit the station. I bought a ticket online the day before and mistakenly ended up with a same-day ticket. I was prepared to buy another but two kind staff members assisted me.
All of the buildings, restrooms, and restaurants are accessible. There are ramps throughout but you need to be able to take stairs to get up close to some of the rolling stock. It's an extensive collection on the main floor. A lot of upstairs is kid-directed but that doesn't mean adults wouldn't enjoy it. There are escalators and elevators.
At 10:30 I went to the 4th floor of the South building, a short walk away, and ate at the View Restaurant. It's a small menu with items for adults and kids. Order at a machine first (English available), select your main dish by itself or of your want to bundle it with a drink. (No diet soda.) There are only two machines, and the far one takes only Suica/IC cards. I think there are only two machines so neither the kitchen nor the dining room gets overwhelmed. Turn in your ticket at the counter behind you and you'll get a buzzer that will notify you when it's time to pick up your food. I had hamburg steak with karaage chicken, ham, and fried egg. Rice and cabbage too, of course. It was fresh and tasted good. Tables next to the window have an unobstructed view of passing Shinkansen; of course those get filled immediately. (The museum is sandwiched between the Shinkansen tracks on one side and local and freight train tracks on the other.)
Just outside the restaurant is a terrace with tables and where you can watch Shinkansen and other trains go by. You can eat in the train car restaurant or get ekiben at a little outside stand between the main and South buildings. The ekiben selections include special train-themed containers.
There are drink vending machines sprinkled around, and benches at ground level in various places so you can watch local and freight trains go by. Naturally I had to spend a little money in the souvenir shop before departing.
I saw kids running laps through and around cars, followed by parents desperately trying to corral them. In one case, a child was literally bouncing off the seats. A little girl in a princess dress lovingly hugged a bag that had a Shinkansen model peeking out of the top. A freight train ambled past while commuter trains moved more quickly on several different tracks.
My joints began to really ache around noon, necessitating more time seated and pain medication. So I guess my body gave out before the kids. But it doesn't matter because we all had a good time.
