The Ruby Foundation (Location: Minato-ku, Tokyo; Representative Director: Yutaka Ito; hereinafter referred to as "Ruby Foundation"), which aims to create a "Rubiful" society where everyone can learn easily and multiculturalism coexists by appropriately increasing furigana (ruby) in society, announces that a "Rubiful Books" fair is being held at Maruzen Junkudo Shoten, Maruzen Marunouchi Main Store.
In Japanese, it can be difficult to understand content without being able to read kanji, and it is more difficult than looking up English words written in alphabet, making the existence of unreadable kanji a hurdle to reading. The Ruby Foundation believes that if books are appropriately marked with ruby, children and people who are not good at kanji can read books in fields that interest them, expanding their possibilities, and therefore is engaged in selecting "Rubiful Books" with abundant furigana.
Maruzen Junkudo Shoten has been working to create an environment where a wide range of readers, from children to adults, can find books that suit them by establishing a permanent corner for "Rubiful Books" from December 2025.
To commemorate "Ruby Day" on June 2nd, we are holding a "Rubiful Books" fair. At the venue, approximately 200 titles of Rubiful Books from various genres are introduced, categorized into "Full Ruby," "Heavy Ruby," and "Light Ruby," and the award-winning works of the "Rubiful Book Award 2026" are also on display.

◆ About the Rubiful Book Award
The Rubiful Book Award is an award that honors "books that reached readers precisely because they had ruby (furigana)."
The difficulty in reading books lies not only in the content itself but also in "not being able to read kanji." Ruby removes that barrier, opening up opportunities for reading to more people.
This award highlights books that are creating a wider range of "readable people" by having abundant ruby applied.
