Thirty minutes over Tokyo

Do you know the episode which is named "Thirty minutes over Tokyo?"

It has never been aired in Japan even it describes about Tokyo.
The reason might be some descriptions in the episode are not appropriate to be aired in Japan.
For example, Homer throws a Japanese Emperor. And even its title is a parody of "Thirty seconds over Tokyo" which describes about the Doolittle Raid.
