The official Japanese Movie 18 website has updated with information on the Next Generation World Hobby Fair '15 Winter. Translations follow:

This winter's Next Generation World Hobby Fair starts Sunday January 18th! It will be held at 4 venues across the country, starting with Nagoya!

The Pokémon booth will be filled with the latest Pokémon information!
Make sure to get information on this year's movie, which title has just been announced as "The Archdjinni of Rings: Hoopa", as well as on the new Pokémon "Hoopa" itself!

At the Pokémon movie corner, we'll give out fliers full of information on the new Pokémon "Hoopa"!
In addition, we will offer an "Appear! Box Challenge", named after Hoopa's "mysterious power that makes it able to summon all kinds of things, Pokémon and people included, with its rings"!
Take the correct Pokémon out of the "Appear!" box and win a special sticker set! In addition, all participants, including those who fail the challenge, will be given a post card!
Come take the challenge at the fair!
