- A man calls Kubo in the first scene to ask about T-shirts of the tokusatsu show Mighty Jack.
- Kubo's clothes are Amuro Ray's civilian clothing in the first few episodes of Mobile Suit Gundam.
- When the characters reunite each other in the lift they talk about a Gundam parody.
- Satou brings out a Captain Harlock sticker.
- They talk about a "ditz" in a Minky Momo costume.
- The DVD cover on the main page features Tanaka doing the Vulcan salute from Star Trek.
- At the school festival:
- We see a Godzilla cosplayer in the background.
- Tanaka dresses up as Char Aznable from Mobile Suit Gundam.
- Satou dresses up as Lum from Urusei Yatsura instead of Artesia, because that outfit was sold out.
- We see an image of Sayla (Artesia) and Lalah on a store sign at the festival.
- Tanaka says he'll throw in the blueprints for Zambot 3 if Kubo buys one of his doujinshi.
- When the other Otaku at the festival love-bomb Kubo, we see in order of appearance; Susumu Kodai (Space Battleship Yamato), Joe Shimamura (Cyborg 009), Bright Noa (Mobile Suit Gundam), Lalah Sune holding up a Haro model (Mobile Suit Gundam), Arale (Dr. Slump), Maetel (Galaxy Express 999), Captain Harlock, Arsene Lupin in Green (Lupin III) and a glimpse of Jigen (Lupin III)
- Zooming out we also see, Ken the Eagle (Gatchaman), a Zeon soldier (Mobile Suit Gundam), Doraemon (Doraemon), Sazae San (Sazae San), a Black Tiger fighter pilot (Space Battleship Yamato), Goemon Ishikawa XIII (Lupin III) and a Blonde Baam (Tosho Daimos).
- Kubo also looks like Marty McFly (Back to the Future) from this distance.
- At "headquarters" Tanaka has custom movie poster featuring a VF-1S Valkyrie from Macross and Arsene Lupin.
- Opening the door Tanaka and his friends says Sususmu Kodai's lines when he uses the Wave Motion Gun from Yamato.
- Miyoshi does his best to resemble the XO, Shiro Sanada, from Space Battleship Yamato — including both his haircut and the Yamato T-shirt.
- When Tanaka explains the story for GX's new "Misty May" series, we see a group of girls in the background strongly resembling B-Ko and her Girl Posse from Project A-ko. (Particularly note the Brawn Hilda in the background.)
- Misty May's companion critters, lion cubs Posi King and Negi King are nods to Magical Angel Creamy Mami's cats, Posi and Negi snd Nadia's pet lion, King.
- The background music for the final scene of Tanaka and Kubo approaching the underwater Eltrium sounds a lot like the famous instrumental theme from Gunbuster. Heck, the Eltrium itself even resembles the Gunbuster crossed with the Yamato.
- Each anime segment was ended with a reference and date of an important real-life event in the year in which the segment was set. Near the end, when events start taking place in the not too distant future, the second-to-last reference was to a nuclear waste explosion on the moon causing the moon to be blown out of orbit. The date was said to be September 13, 1999.
