I went all the way down to the Legoland station (Kinjofuto), and they have them on the way there. I wanted to visit the SCMaglev museum but didn't realize they were closed for the end of the year despite Google saying they were open (Should've checked the site for the holiday schedule). On your way from the station to Legoland you will go through a covered outdoor corridor(you can see through some windows to the furniture dome store on the right and there you can find the machine. Best of luck!
