ⅠArt
Contemporary Art
Recipient of seventeen international art awards. Exhibiting across Europe, Asia, and the Americas, and featured in art books and academic journals, Hirokawa creates work grounded in a distinctly Japanese sense of prayer — exploring collective psychology, the structures of perception, and fundamental consciousness.
Beneath these works lies a way of seeing time not as a flow but as a chain of causation. The images trace the boundary between dream and reality — where human consciousness, beauty, and decay intersect — in the twin languages of poetry and mathematics.

It was not that I wanted to know humanity. Something wanted to know humanity — and through this body, it watches the ways of the heart.

ⅡApps
iPhone / Android Apps
Technology, too, can be a vessel for beauty. Designed with the same eye as the artworks, these apps have surpassed 50 million downloads and are used every day by more than 3 million people each month.
Japanese Woodblock Art App
Ukiyo-e Wallpapers
More than 1,000 masterpieces by Hokusai, Hiroshige, Utamaro, and Sharaku. Each print is individually restored — creases and stains carefully removed — to preserve the vivid crimson and indigo of the originals.
Wish & Habit Support App
Law of Attraction Everyday
Putting a wish into words, and returning to it every day — an app designed for these two practices. Compose your own affirmation from around 200 sample phrases, and let it grow into a daily habit.
Sleep & Relaxation Sounds App
Relaxing Healing
Healing music and ambient sounds — rain, birdsong, waves. As sleep approaches, the timer lets each sound recede little by little.
Love cannot be taken apart, nor can it be combined. What admits nothing smaller and nothing larger is what we call an axiom.

ⅥProfile & Awards
About Masaki Hirokawa
Masaki Hirokawa — Contemporary Artist & Digital Creator. A graphic and contemporary artist and app developer, recipient of 17 international art awards. Through exhibitions across Europe, Asia, and the Americas, and features in art books and academic journals, he creates work grounded in Japan’s distinctive sense of prayer — exploring collective psychology, the cognitive world, and fundamental consciousness.
Drawing on natural symbolism, philosophical reflection, and imagery inspired by contemporary science, he seeks to soften the divide between the sacred and the secular, and to restore the subtle bonds between human beings and the natural world. Across his practice, subtle synesthetic sensibilities and a quietly mystical inspiration coexist.
Beginning with self-taught web design in 1997, his path led through systems engineering, writing for design publications, and game development to founding an independent app business in 2013. Since 2019 he has resumed full-scale art production — bridging art and technology, pursuing expressions that inhabit the space between the digital and the poetic.
