I have been to owarai performance live show for the first time last week.
Comedians who were in the live show are not famous but it was so funny.
Ticket costs only 1500 yen and they have different kinds of performance show everyday.
You can see it at 5up yoshimoto which is just located in front of Namba grand kagetsu.
They also have an event at Suma beach as well.
It's highly recommended to watch the comedy performance when you visit in Osaka:)
