About INSTINCTOY

INSTINCTOY is a Japanese designer toy brand founded in 2005 by artist Hiroto Ohkubo, known for premium soft vinyl figures built around the Erosion Monster concept — characters that infest or merge with hosts, most notably Muckey (introduced 2013) and Monster Fluffy (2019). A 2019 collaboration with Takashi Murakami produced a sofubi edition sold through the MoMA Design Store. INSTINCTOY partnered with Pop Mart in 2020, launching the Relax and Shock blind box series and expanding into plush pendant and gift series. TOYSEZ maintains a complete database of all INSTINCTOY blind box series, limited editions, and secret figures — including release dates, collection URLs, and a full chronological series guide for collectors.

Designer: Hiroto Ohkubo

Hiroto Ohkubo is the founder and sole creative force behind INSTINCTOY, the Japanese designer toy brand he established in 2005 at the age of 22. Self-taught through years of collecting, Ohkubo began producing his first original soft vinyl figures in 2008, developing a signature aesthetic rooted in what he calls the Erosion Monster concept — creatures that infest, merge with, or inhabit other characters, resulting in forms that sit uneasily between cute and disturbing. In 2013 he introduced Muckey, a bear character whose head is partially overtaken by Fluffy, a symbiotic flying creature. The relationship between host and parasite — and the expressiveness achieved through movable parts — became the defining language of his work. In 2019, a collaboration with Takashi Murakami produced a sofubi edition of Murakami's Mr. DOB sold through the MoMA Design Store, one of the highest-profile institutional validations of the designer toy form. That same year, Ohkubo launched Monster Fluffy as a standalone figure and began his collaboration with Pop Mart, which brought the Relax and Shock series to international audiences starting in 2020. INSTINCTOY's 20th anniversary was marked in December 2025 with an archive exhibition in Daikanyama, Tokyo.
