Announced on Twitter, some translated tweets coming:
"Thank you for attending my Christmas concert!! We announced this during the concert, but my next song will be an opening theme for the anime "Pocket Monsters XY"!! It will premiere in January next year, so look forward to it!!!"
"Thank you so so much for today. It was a real pleasure to spend Christmas with you all. Thank you so much for celebrating my birthday, too! (*his birthday is the 26th of December) Me doing a Pokémon OP is also a miracle that happened because you've all always been cheering me on. There's so much I want to do for you next year as well, so bear with me from here on too."
"The title of the song is "Getta banban". It's an upbeat, positive song filled with the kind of things I love, made with Pokémon in mind. It's a really cool song. Make sure to check out this Pokémon OP, which starts next year!!!"
"I love Pokémon, so I'm really really happy about this. Next year will be so fun I'm all embarrassed thinking about it."
"You'll get to hear a bit of my new OP that premieres next year during the Pokémon special on December 31st! Check it out!!!"
"My dream is to become a Pokémon Master! I'll work hard!!! It still hasn't been decided when the next song will be released, but we want to do a lot of release events all over the country! This year there were so many times I didn't get to meet many of you due to the lack of such... Please treat me well when that time comes."
