"Pokémon Radio Show! The Rocket-Dan's Secret Empire" (Pokémon Radio Show! ロケット団ひみつ帝国) was a radio show that was broadcast on 76.1 interFM in Tokyo, Japan. The 30 minute radio show aired every Sunday evening from 7:00pm until 7:30pm JST from July 1st, 2012 until December 23rd, 2012. 

The premise of the radio show is that Musashi (Megumi Hayashibara), Kojirou (Shi-ichiro Miki), and Nyarth (Inuko Inuyama) are trying to recruit the earth's population of 7 billion people into the Rocket-Dan to help their beloved boss Sakaki realize his dream of world domination. To do this, the Rocket trio decide to have a secret radio show every week to entice listeners to join them.

Ms. Hayashibara, Mr. Miki, and Ms. Inuyama would perform the entire radio show in-character. Their guests would be introduced as either people who have raised certain Pokémon or as friends of the human characters.  Yuuji Ueda, for example, was introduced as Takeshi's friend (Yuuji Ueda does the voice of Takeshi) and as someone who's raised a Sonansu (Yuuji Ueda also does the voice of the Rocket-Dan's Sonansu). While there is generally an attempt to keep things as in-universe as possible, discussions about the voice actors' auditions and the work they've done for other TV series pop up from time to time as well.

The radio show was first announced via a special Twitter account (which has since been deleted) created just for the show. Masafumi Mima (三間雅文), the sound director for every Pocket Monsters series since the first one back in 1997, got the project off the ground and was put in charge of organizing the show. According to this tweet made by Mr. Mima on his Twitter page, it took a year and a half of planning to finally get the radio show off the ground.

Segments

The show had a number of recurring segments throughout its 26 episode run. These include:

Opening Sketch (冒頭) - Musashi, Kojirou, and Nyarth perform a mini play, often ending on some kind of joke. These sketches would often be parodies of various well-known stories -- Little Red Riding Hood, detective dramas, Star Wars, etc.

"Welcome, Pokémon Day Care Worker!" (ポケモンの育て屋さん、いらっ しゃーい) - Musashi, Kojirou, and Nyarth invite other Pocket Monsters voice actors to the studio and talk with them for about ten to fifteen minutes. In the context of this show, the guests weren't voice actors who voiced certain Pokémon; they were "Day Care Worker Specialists" who "raised" certain Pokémon. Some voice actors were better at playing along with this than others. The Day Care Worker Specialists (voice actors) would bring (perform the voices of) Pokémon on the show and tell stories about raising them (voice acting). Each of these segments began with an introductory rap.

"The Rocket-Dan is Quizzed on Their Knowledge of the Super Short Intros" (ロケット団知識チェック ぎゅうっと短いイントロクイズ) - Nyarth has Musashi and Kojirou listen to the first one or two seconds of a Pocket Monsters song and has them guess what the title is. The quiz would sometimes be made more difficult by playing the intros at double speed, playing the intros backwards, or by throwing non-Pokémon songs into the mix.

"The 'Orders from Double-Q - Try These New Items Out Ahead of Time' Segment" (QQ指令 先取り 新アイテムためしてなんぼのコーナー) - Double-Q, introduced in Episode 02 as being the Rocket-Dan's Weapons Development Division (ロケット団新兵器開発部) gives the Rocket trio products -- most of them food -- to try out on air. Pictures of the products being promoted would be posted on the Rocket-Dan's Twitter account.

"How Well Do You Know Pokémon?  The Drawing and Crying Marumine Segment" (ポケモン知識チェック 描いて泣いてマルマインのコーナー) - Musashi, Kojirou, and Nyarth are given 30 seconds to draw certain Pokémon / Pokémon characters purely from memory. They would then take turns guessing what each other's drawings were. Pictures of their drawings were posted on the Rocket-Dan's Twitter account so listeners could play along.
