Although I had to wait for 20 minutes due to the store's mistake in scheduling the wrong time, the overall experience was great. The guide's English was good enough to communicate. The tour involves driving go-karts to various Osaka attractions for photo opportunities. Note that you won't enter Osaka Castle itself, only view it from a distance. I recommend scheduling this for your first day to get acquainted with the area. Also, unlike other go-kart tours that use smelly diesel engines, this one uses electric vehicles, so you won't have that problem. Driving on the road makes you the center of attention – tourists and locals alike will constantly say it's cool, take photos of you, or wave hello. The traffic is very safe, so no need to worry. The guide will also use hand gestures to guide you appropriately.
