A Long-Awaited Collaboration with Three Beloved Anime Masterpieces! In-App Event "3 Consecutive Tatsunoko Pro Festival!!" Featuring Hakushon Daimaou, Yatterman, and Gatchaman Announced

17LIVE Inc. (Shibuya-ku, Tokyo, Representative Director: Jiang Honghui, URL: https://jp.17.live/), operator of Japan's largest live streaming app "17LIVE", announces that it will hold an in-app event, "3 Consecutive Tatsunoko Pro Festival!!", from Wednesday, April 1, 2026, to Thursday, April 30, 2026. The event will feature consecutive collaborations with the national classic anime "Hakushon Daimaou," "Time Bokan Series Yatterman," and "Science Ninja Team Gatchaman," produced by Tatsunoko Production Co., Ltd. (Musashino-shi, Tokyo, President and Representative Director: Jun Togawa), a studio known for producing beloved classic animations over many years.

At "17LIVE", we hold various collaboration projects and events every day with the hope that liver (live streamers) who are already streaming and those who have never streamed before will enjoy live streaming. This time, through a collaboration with "Hakushon Daimaou," "Time Bokan Series Yatterman," and "Science Ninja Team Gatchaman"—works that still enjoy high popularity and support from a wide range of generations even half a century after their broadcast began—we decided to implement this event in the hope that it will provide an opportunity for more people to experience the fun and approachability of live streaming.

TV broadcasting began in 1969 for "Hakushon Daimaou", 1977 for "Time Bokan Series Yatterman", and 1972 for "Science Ninja Team Gatchaman". All of these works gained immense popularity, especially among children, and even now, about 50 years later, they continue to receive high support from many generations, with remakes and live-action versions being produced and merchandise being sold.

The three in-app events held as the "3 Consecutive Tatsunoko Pro Festival!!" are open to anyone who is a user of "17LIVE". During the event period, original collaboration gifts (paid) with motifs of each anime work will be available. Users who achieve certain conditions based on the number of points earned from gifts or those ranked high will be awarded collab digital prizes for each work and exclusive original goods limited to this event.

Please pay attention to this event, which marks the first collaboration with "Tatsunoko Production", a studio that has produced numerous anime works beloved by a wide range of age groups even after half a century.

■ About Hakushon Daimaou
Hakushon Daimaou is a wizard who pops out of a magic bottle whenever someone sneezes to grant the wishes of the person who summoned him.
However, the clumsy demon king constantly fails when following the orders of Kan-chan, the elementary schooler who became the owner of the bottle.
Furthermore, the mischievous demon king's daughter Akubi, who pops out when someone yawns, joins in, causing huge uproars throughout the town.
A side-splitting slapstick gag comedy unfolding with a cast of highly unique characters.
Numerous sequels and spin-offs have been produced, and its characters continue to be loved by various generations over many years.

■ About Gatchaman
To counter the evil secret society Galactor plotting world domination, Dr. Nambu of the International Science Organization forms the Science Ninja Team, a special team of five boys and girls.
The Science Ninja Team confronts Galactor, who plunges the world into chaos, by utilizing Science Ninja Arts and various mechas.
While it is a rewarding-good-and-punishing-evil hero story depicting the battle between justice and evil, it is also a monumental sci-fi hero action work that gained fans across a wide age range by raising the alarm on social issues like war and pollution, and depicting profound human drama such as friendship among comrades and parental love.

■ About Yatterman
The second installment of the Time Bokan series. Over the Skull Stone, which is said to indicate the location of a great gold ingot, the heroes of justice Yatterman and the villainous trio Dorombo Gang travel the world engaging in a fierce contest.
The definitive hero gag comedy that established the popularity of the series.
