Ryōgoku Peter Pan 2010: Summer Vacation (両国ピーターパン2010 〜夏休み ああ夏休み 夏休み〜, Ryōgoku Pītā Pan 2010: Natsuyasumi Aa Natsuyasumi Natsuyasumi) was a professional wrestling event promoted by DDT Pro-Wrestling (DDT). The full official name of the event could be translated as "Summer vacation! Ah! Summer vacation, summer vacation...". The event took place on July 25, 2010, in Tokyo at the Ryōgoku Kokugikan. The event featured nine matches, three of which were contested for championships.[1][2] The event aired on Fighting TV Samurai and the dark match was broadcast on ustream.
As in the previous year, Michael Nakazawa's anal blast was held as the opening ceremony. The amount of gunpowder was twice that of the previous year. Announcer Hidekazu Tanaka was the host of the ceremony and Masahiro Chono triggered the detonation.
The next match involved Tajiri from the newly founded Smash promotion.
In the sixth match, Naomichi Marufuji from Pro Wrestling Noah was originally supposed to face Kota Ibushi, however, due to Ibushi suffering an injury before the show, his tag team partner Kenny Omega was named as his replacement. Because of this, Omega had to vacate the Sea of Japan 6-Person Tag Team Championship he was holding with Mr. #6 and Riho since June 13,[4] and Great Kojika was declared champion on July 20 so that he could defend the title at Ryōgoku Peter Pan 2010.
