'Ehon no Kutsushita Grand Prix 2026' Starts in June! First Fan Voting Event for the Series Surpassing 1 Million Pairs Sold

Oyako no Jikan Kenkyusho (operated by Live Enterprise Co., Ltd.), which plans and manufactures picture book character merchandise, is holding the first-ever fan voting event, 'Ehon no Kutsushita Grand Prix 2026,' for its apparel series 'Ehon no Kutsushita' (Picture Book Socks). The event will take place starting in June at bookstores across Japan that feature 'Ehonya-san MOE' sections (with some exceptions).

This event invites users of the 'Ehon no Kutsushita' series—which currently has a lineup of over 100 designs—to vote for their favorite designs along with the memories they associate with the picture books.

■ Voting based on 'memories,' not just 'designs.' A new attempt to connect fans and picture books

'Ehon no Kutsushita' has been developed to accompany the daily lives of picture book fans. The lineup has now expanded to over 100 varieties.

This event is not simply about ranking favorite designs. It aims to have fans vote based on their 'memories of picture books' associated with their socks, using this feedback to guide future product development that resonates with fans. The goal is to create an event where mutual thoughts and feelings can be shared.

■ Bookstores nationwide turn into a 'small picture book library'! Delivering the 'excitement of choice' unique to physical stores

Votes for this event can be cast via QR codes on store POP displays where 'Ehonya-san MOE' sections are located, or via a special website. The sight of 'Ehon no Kutsushita' lined up on store shelves creates an exciting atmosphere like a 'small library.' In an age where online shopping is the mainstream, this project creates an opportunity for customers to visit physical stores, providing the experiential value of 'enjoyment of choice' at the bookstore.
