Not to worry, convenience won't interfere with the view—it's located on the first floor of the existing east rest house across from Osaka-jo Hall, a 16,000-seat arena that's been on the grounds since 1983.

The Osaka Castle Lawson includes an eating area with seven seats, and you can pick up Osaka Castle souvenirs as well. Six more mini-shops will be opened on the grounds after May 2016. So now if you feel in the mood for a Premium Roll Cake, you don't even have to leave the safety of the castle walls!
