We took a high-speed train from Kyoto to Shin-Osaka station and are staying at a hotel attached to the station. The next day, we took a local train to see the Osaka Palace. This train has "women only" cars. Our Tokyo tour guide told us about these train cars, necessitated by men groping women on trains.
Osaka Palace has an observation tower where you can view the town. We chose not to ascend the tower, but here's a picture of the turret.
With all of the shrines, temples and palaces on this trip, we were feeling too cultured and decided to do something kitschy, so we visited a ramen museum.
