If you’re even the least bit interested in railways and train paraphernalia, this is the spot for you: the Tobu Railway’s own museum displays the company’s achievements in a way that appeals to train geeks of all ages. Dioramas and miniatures aside, the building houses several retired train cars (most of which can be entered) and a couple of train simulators (stopping at the station can be surprisingly difficult!), while the room on the top floor is where you can peek through the rail-level windows to see trains passing or making a stop at Higashi-Mukojima Station. Many of the displays move or display special features at set hours throughout the day. Finding the entrance can be a bit tricky: step out onto the east side of Higashi-Mukojima Station, take a right and you should see the doors on your right side.
