If you've never visited a ninja museum or show before, this would be the place to go for first timers. You can buy tickets for only the museum or the museum & show. Be sure to check the times for the show first before getting tickets. They give you a tour of the house & then you can go downstairs to see the museum. At the exit there is a little shop where you can buy some souvenirs like plastic shurikens. It's worth going to if you have some time from Osaka or time have some time travelling between Tokyo & Osaka.
