The Junichi Sato Comedy That Came Before Sailor Moon
Goldfish Warning! is a slapstick school comedy, and international fans will recognize its pedigree the moment they see the staff list. Junichi Sato (series director of Sailor Moon, chief director of Princess Tutu, director of Aria the Animation) was series director on the show at Toei Animation, roughly a year before he took the reins on Sailor Moon at the same studio.
The report from Japanese anime news site Anime Hack on the streaming plan leads with Sato's credit, and it's the obvious hook. Goldfish Warning! never had the global footprint of the magical-girl shows that followed it, so for many viewers outside Japan this will be a first look at an early piece of his career.
The series aired on TV Asahi from January 12, 1991 to February 29, 1992, for a total of 54 episodes. Each broadcast is split into two roughly 11-minute stories, which is why Toei counts the run as 54 episodes but 108 stories.
What the Show Is About
The premise is pure gag-comedy setup. Chitose Fujinomiya, a girl from the city, transfers to a middle school out in the countryside. She brings along Gyopi, a pink goldfish said to be the only one of its kind in the world. Once there, she gets pulled into the chaotic daily routine of Wapiko, a relentlessly energetic classmate, and the rest of the student body.
The episode 1 title on YouTube spells out that setup in two halves: "Tenko Shojo Fujinomiya Chitose!" (Transfer Student Chitose Fujinomiya!) and "Minna Atsumare! Pink no Kingyo no Tanoshii Gakko" (Everyone Gather Round! The Fun School of the Pink Goldfish).
The voice cast is a who's who of early-'90s Toei talent. Mika Kanai plays Wapiko, Yumi Takada voices Chitose, and Minori Matsushima handles Gyopi. Satoru Iriyoshi did the character designs and Takanori Arisawa composed the music.
The anime adapts the manga of the same name by Neko Nekobe, which ran from 1989 to 1993 in Nakayoshi, Kodansha's long-running shojo magazine. The source article lists the magazine as "Nayokashi," which is a typo for Nakayoshi.
How the YouTube Schedule Works
The rollout runs on a fixed weekly schedule. Episode 1 goes up as a YouTube Premiere on September 21, 2026 at 6 p.m. JST on the Toei Animation Museum Channel, Toei's official archive channel for its older catalog. After that, a new episode posts every Monday at 6 p.m. JST.
The catch is the two-week window. Each episode stays online for only 14 days before it comes down, so the channel will have at most two episodes up at any given time. Anyone who wants to follow the whole series needs to keep pace with the Monday drops rather than binge later.
At one episode per week, streaming all 54 broadcasts would take a little over a year if the schedule runs without breaks. Toei hasn't said whether the 1992 short theatrical film will be included.
Looking Ahead
The premiere lands September 21, 2026 at 6 p.m. JST, with episode 2 following on September 28. The episode 1 video is already listed on YouTube as an upcoming Premiere.
Region availability is the open question for readers outside Japan. When we loaded the Anime Hack page, the embedded YouTube player returned a "not available in your country" message, which suggests the stream may be limited to Japanese viewers. Toei hasn't stated a region policy, so treat that as an early signal rather than a confirmation.
There is no announced English-subtitled release of the anime, and we couldn't find an English publisher for Neko Nekobe's manga. If Toei opens the YouTube run worldwide, it would be the first easy official way for most international fans to watch the show.
