Keroro Wiki

Keroro and Giroro's Pekopon Invasion Radio (ケロロとギロロの地球(ペコポン)侵略ラヂオ Keroro to Giroro no Pekopon Shinryaku Rajio) is a radio program based on the anime and manga series Keroro Gunso.


In each episode, Keroro (Kumiko Watanabe) and Giroro (Jōji Nakata) visit different corners where they converse about the show, or interact with readers from postcards or questions.

Keroro and Giroro's Pekopon Invasion Radio was previously only broadcasted through AniRadio during late nights in Radio Osaka. Although this caused many fans to not have access to the radio program. To solve this issue, Bandai also broadcasted the show on their visual internet radio site "BEAT☆Net Radio!" (as of now this site has been shutdown).

The program would originally air from 24:00 to 24:30, although after April 2007 the time slot was replaced by "CELL DIVISION Keep on Doing". The time was later changed to air from 24:40 - 25:00 on Saturdays. Unfortunately after 2 years and 9 months the radio program would end, and broadcasting would be removed from "BEAT☆Net Radio!".

Main Corners

Listener's Corner

A section in the radio program dedicated to presenting standard letters from fans.

Giroro Bar

A section in the radio program dedicated to Jōji Nakata and Kumiko Watanabe answering questions from fans. In this corner, Kumiko Watanabe and Jōji Nakata do not use their personalities (Keroro and Giroro). Instead they use their normal voice to talk, while a quiet background song is heard to set the bar mood. Although this corner was made to feel more mature, the two voice actors tend to laugh frequently. In result, viewers have tagged this as a funny corner. After this section is concluded, Giroro, the bar owner, ends off with a proverb to close it off. This is one of the most popular corners in this radio show.
