Although I had to wait 20 minutes because the shop made a mistake with the time, the overall experience was great. The guide's English was good enough for communication. The tour involves driving go-karts to various Osaka attractions for photos. However, please note that you won't enter Osaka Castle itself, only view it from a distance. I recommend scheduling this tour for your first day to get a good overview. Other go-kart companies use diesel, which can be smelly, but this one uses electric vehicles, so that's not an issue. Driving on the road, you'll be the center of attention; tourists and locals alike will constantly say how cool it is, take pictures of you with their phones, or wave hello. Traffic is very safe, so there's no need to worry, and the guide will also give you appropriate hand signals.
