(Shinagawa, Tokyo / Representative Director and President: Tatsuya Nanjo), announced on Wednesday, March 25, 2026, the start of distribution of the electronic versions of the four existing books in the "Oshiete! Sanrio Characters" series on U-NEXT "Kids Unlimited Reading". U-NEXT monthly plan subscribers can enjoy these books at no additional charge.

"Oshiete! Sanrio Characters" is a picture book series where children can learn essential knowledge about their bodies and minds from an early age, together with Sanrio characters, to live a better future.

The themes vary, including "Anata no Karada wo Daiji ni Suru Hon" (A Book to Cherish Your Body), which deals with body safety such as private parts, and "Ironna Kimochi Okorutte Naani?" (Various Feelings: What is Anger?), which addresses basic emotions that deepen understanding in early childhood. The series gently and clearly conveys important but often difficult-to-explain themes within the world of Sanrio characters.

Since its launch in December 2024, this highly popular series has seen continuous reprints. It is particularly well-received by children aged 3 to 7, especially around school entry, and their families.
