I went and translated the image and it seems to say this "7,700 yen (including tax) Uses 1 AA battery (sold separately)" so we can see a price and says it uses 1 AA battery. Whether its motorised or not its a 50/50 as I can kind of see a rubber tire in some shots but more over it could be for lights but that's nether here nor there. overall they do look nice and have been thinking of getting some other non-themas related tomy trains maybe try and get a Shinkansen that I had a very long past.
I liked tomy ever since I found out about it
