Actor Hayate Ichinose's Delighted Comment Arrives & First Look at New Photos! "Ichinosekai," a Book Compiling His Popular Series from "BoyAge," to be Released on Wednesday, April 8, 2026

KADOKAWA Corporation (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Tsuyoshi Natsuno) will release "Hayate Ichinose 'Ichinosekai'," a compilation of the popular project by actor Hayate Ichinose serialized in the mook "BoyAge," on Wednesday, April 8, 2026.

The challenge project from the "BoyAge" mook series, where Hayate Ichinose takes on new things to expand his repertoire as an actor, has finally become a book.

Hayate Ichinose has previously challenged himself with flower arrangement, camping, drumming, acrobatics, latte art, golf, painting, soba noodle making, and basketball. For this book publication, he undertook two new experience projects and photoshoots in Singapore: "bartender" and "butler." The book also includes many new photos taken exclusively for this publication.

In response to the massive feedback received immediately after pre-orders began, it has been decided to sell additional slots for the online event.

Along with this, a joyful comment from Ichinose himself, filled with gratitude for his fans, has arrived.

Comment from Hayate Ichinose

I am sincerely happy to be able to deliver "Ichinosekai," where I have challenged various things, to everyone as a book!

It has become a volume packed with the raw and serious Hayate Ichinose that you don't usually see, so I would love for you to pick it up!

To the editors, photographers, writers, hair and makeup artists, stylists, my manager, all the staff who have supported me in continuing this series that I love and is very important to me, and now turning it into a book, and to everyone who will pick it up,

I want to express my heartfelt "thank you."

Let's go on a journey to various "Ichinosekais" together!
