KADOKAWA Turns TXQ FICTION's UFO Mountain Into A December 2 Book

The book extends a television mockumentary past its broadcast ending by handing the investigation to the researcher who appeared in the program, so the follow-up interviews and Higa's own trip to Mount Asahi become the reason to buy the print edition rather than a record of what already aired.

KADOKAWA Turns TXQ FICTION's UFO Mountain Into A December 2 Book

KADOKAWA announced on October 2 that the mockumentary program UFO Mountain will be published as a book on December 2, 2026. The fourth TXQ FICTION installment, which aired on TV Tokyo over four consecutive nights in December 2025, follows the death of mountaineer Shuichi Hachiya on Mount Asahi in Hokkaido. The book adds post-broadcast interviews and new material written by UFO researcher Kotaro Higa, with a cover by Machiko Miroco.

The print edition runs 176 pages in Shiroku paperback format at 1,870 yen including tax, with an e-book released the same day. Ryota Kondo provides the original story. Writing is by Kotaro Higa, a UFO researcher who appeared in the program, and the book adds interviews recorded after broadcast with Hachiya's son, Sora Yoshioka, plus a section in which Higa travels to Mount Asahi himself. Purchase bonuses are split by retailer: audio data titled "New Voice Memo Discovered on Mount Asahi" at Amazon, video data titled "New Footage Discovered at a University Near Mount Asahi" at Rakuten Books, viewable on a dedicated page, and image data titled "Kotaro Higa's Investigation Notes" for the e-book.
