The official Pokémon movie website has updated. Translations follow:

A Status Report from the Next Generation World Hobby Fair '17 Summer!

The Next Generation World Hobby Fair '17 Summer was held at Makuhari Messe Saturday June 24th and Sunday June 25th.
Since the movie is going to premiere soon,
the Pokémon Booth was filled with tons and tons of info on "Pocket Monsters the Movie: I Choose You!"
The "Latest Pokémon Movie News Stage Show" was hosted by Abareru-kun and Rinka Otani on day 1,
and by Shoko Nakagawa and Rinka Otani on day 2.
These shows were packed with content: They'd play "Fully Powered Pose 1-2-3!" with the visitors,
hold quizzes, occasionally have concerts... and lots more.
When they asked "Are there any dads or moms here that watched the first movie,
"Mewtwo Strikes Back!", as a kid?"
several people raised their hands,
truly letting you relive the 20 years of history that Pokémon now has.
The fact that so extremely many people showed up
strongly got across how much everyone anticipates this movie!



The Pokémon Booth also had the "Okido Laboratories", which let you experience the world of "Pocket Monsters the Movie: I Choose You!"
Lots of people were lined up here as well,
in order to search for Pikachu inside the laboratories!
There was also the "I Choose You!! shouting contest",
which measured how high the visitors shouted "xxx! I Choose You!"
Lots of visitors wanted to try this, so the excitement level was high!



The Pokémon Booth also had a trial play area featuring the first Pokémon game for the Nintendo Switch,
"Pokkén Tournament DX".
Lots of people were lined up here to play this game early.
There was also a "Japan's First Pokkén DX Battle Show" held at the Pokémon Booth stage,
and lots of visitors raised their hands in order to challenge self-appointed Pokkén Master Akira!



The "Z-Move Battle Laboratory & MonCollé Stage Show" was filled with fun,
including a presentation of the "Get Fully Powered with Rotom! Z-Move Laboratory" toy scheduled for release in July,
a 20th anniversary MonCollé quiz, and more!
And at the "Special Pokémon Ga-Olé Concert",
not only was the "Special "I Choose You Cap Pikachu" Ga-Olé Disk" you receive when you go see the movie battled with,
Hideaki Takatori, Aya Ikeda and Tatsuyuki Kobayashi also showed up and performed the Pokémon Ga-Olé theme song live,
all to great excitement from the audience!



The "Pokénchi Presents A Special "Pocket Monsters the Movie: I Choose You!" Stage Show" was held at the Next Generation WHF Stage Saturday June 24th!
Pokénchi residents Shoko Nakagawa, Hyadain, Abareru-kun and Rinka Otani were there,
all wearing Satoshi hats!
And of course, Pikachu later appeared as well, leading to the venue breaking out in excitement!
Professor Ichiohka came on stage as well,
bringing with him an aluminium balloon that accurately replicated the legendary Pokémon "Houou"'s actual size.
When the aluminium balloon spread its wings, it became as big as the entire stage itself,
shocking both the hosts and the audience.

Later, Satoshi's voice actress Rica Matsumoto showed up as a special guest!
After enjoying a fun Pokémon Quiz with the audience,
everyone watched a special trailer for the movie together.
This special trailer was filled with nothing but intriguing scenes,
including Satoshi's first meeting with Pikachu and his subsequent profound dialogue, a look at Marshadow, and more!



After that,
Hyadain and Abareru-kun had a Pokémon battle where they used the mythical Pokémon "Marshadow",
which you receive in "Pocket Monsters Sun/Moon" when you go see the movie,
and which you can't meet during normal gameplay!
Everyone were surprised at how powerful Marshadow's exclusive Z-Move "Soul-Stealing 7-Star Strike" was!

Finally, Rica Matsumoto sang the opening theme for this year's movie,
"Mezase Pokémon Master 20th Anniversary"!
Her powerful singing voice got everyone into a great mood!
