It's been decided that 2-hour specials will be shown across 2 weeks, on Saturday July 6th and Thursday July 11th, to celebrate the premiere of "Mewtwo Strikes Back Evolution"!

First off, we will air the 20th anniversary Pokémon movie that tells the story of how Satoshi and Pikachu met,
"Pocket Monsters the Movie: I Choose You!",
on Tv Tokyo Saturday July 6th at 12:30pm.



Then, we will show the "2 Hour Pokémon Special in Celebration of "Mewtwo Strikes Back Evolution"'s Premiere! Let's Watch "Everyone's Story" with Everyone"
on all 6 stations on the TV Tokyo Network on the eve of the movie's premiere, Thursday July 11th at 6:55pm.
This will be the world's first ever TV brodcast of the 2018 movie "Pocket Monsters the Movie: Everyone's Story"!
And not only that...! We'll also have a live "Mewtwo Strikes Back" last minute pre-premiere segment!!
Hyadain, Abareru-kun and Sunshine Ikezaki are looking forward to the movie premiere. These good Pokémon friends (=Pokénds) have decided to watch "Everyone's Story" together! Shoko Nakagawa will also join them towards the end of the broadcast!



In addition, the TV data broadcast will be linked to Twitter, so everyone's tweets will be shown on-screen as the movie is airing!
We'll make this a "supportive broadcast" where we'll all talk together and support the characters as we watch the movie.
If you attach the hashtag ＃ミュウツーの逆襲前夜祭 to your tweets, your tweets may be shown on the TV screen!
Let's all enjoy "Everyone's Story" together while looking at the supportive comments, everyone!
*The Twitter data broadcast link will only be used in the TV Tokyo Network broadcasts.
*The tweets will not be displayed in recordings of the program.

In addition, just like last year, we'll broadcast a live commentary show via Twitter Periscope starting roughly 6:30pm on Thursday July 11th!
This will be a program providing live commentary alongside the broadcast of the "A 2 Hour Let's Watch "Everyone's Story" with Everyone Pokémon Special"!
The hosts' excitement over the movie as they watch it will be broadcast live on Twitter!
We will also invite Tetsuo Yajima, who directed "Everyone's Story", and have him tell us exclusive behind-the-scenes secrets about the movie!
The hosts will also tweet supportive tweets themselves as they check the viewers' tweets, using Twitter to make this viewing of "Everyone's Story" alongside everyone in Japan even more special!
