Oubliettes and other Sealed Rooms in the Middle of Nowhere in Anime and Manga.
- In the American dub of the 1st Movie of Cardcaptor Sakura, Clow Reed sealed his student (and former girlfriend) in an alternate dimension after she started practicing dark magic. Although she is long dead, her spirit is stuck in there, waiting for him to come back and set her free. Whether or not he ever intended to do so and when is unknown. Sakura has to set her free and help her move on to the afterlife, as this (very) unfriendly ghost attacks her and her friends.
- In the original Japanese version, however, it is not an example of this trope, but rather of a Soul Jar, as the "seal" was voluntary on the sorceress' part (since she was waiting for Reed, her rival and secret crush, to return).
- Clear Card revisits this trope when Sakura's room turns into one of these as a result of one of the new cards. The room seemly has no way out, and pushing on the walls only causes it to stretch. It soon begins to actively try to kill them, but they find a way to escape rather quickly when they realize it's made of rubber and so can be popped with a sharp object like you can a balloon.
- In The Castle of Cagliostro, Lupin III is dropped down an oubliette into a dungeon filled with bones that date across centuries.
- Code Geass R2: After having (seemingly) lost Nunnally in the FLEIJA explosion and getting betrayed by the Black Knights, Lelouch pulls this with his then immortal father inside the World of C by destroying the entrance from the inside in order to take him down with himself as his then would be final act.
- In Dragon Ball Z, the Hyperbolic Time Chamber becomes this if one stays in it for more than two days, or if the door is destroyed, as happens during the Buu saga.
- In Himitsu no Akko-chan episode 32 (the original 1969 series) Atsuko "Akko-chan" Kagami, to gain an empathic insight about her new deaf-mute friend, wishes herself deaf and mute as well. After realizing that not only she got her wish, but she got it so literal that her magic mirror took the liberty to remove her ability to vocalize as well, she runs away in distress, falling in a ravine. She then realizes that a. she can't hear, so she can't possibly know if someone is approaching the edge of the crevice and b. even if she somehow managed to know that, she'd still be unable to cry for help.
- In Kirby: Right Back at Ya!, Kirby himself may be considered a Sealed Room In The Middle Of Nowhere. In one episode, he inhales a Dedede doll, which means he also inhaled Dedede himself due to the circumstances. At the end of the episode, Dedede and said doll are shown floating in what looks like outer space. This makes for less of a room and more of an alternate dimension of nothingness. It is never explained how Dedede escaped, but one can presume that the other characters figured out what happened and convinced Kirby to let him go.
- Maria no Danzai: This is the fate that Maria sentences Kumiru Shikimi to. It certainly didn't hurt to force Kumiru to injure her face beforehand, or subject her to Creepy-Crawly Torture as she dies, mirroring the torments she put Kiritaka through. But ultimately, Maria couldn't think of a more perfect way to kill a bully who manipulates everyone around her and uses her appeal to get attention and money than to simply leave her to die alone in an abandoned well, with no chance of rescue.
- In Rurouni Kenshin, Hell (or The Underworld, depending on your translation) is this... inside of a pocketwatch.
- Sailor Moon: In the Anime, this is basically how Nehellenia's Can works from her perspective, though she also seems to have been asleep for awhile too. It also seems to function as a Year Inside, Hour Outside, since Nehellenia, having failed to seize immortality through the Golden Crystal, regains her youth when Queen Serenity's curse re-seals her. Disturbingly, she doesn't even try to escape it, outright admitting that she accepts eternal isolation if she can truly be beautiful forever. It's actually kinda hard not to feel sorry for someone whose self-worth is that low.
