IC4DESIGN
IC4DESIGN is a Hiroshima-based illustration and design studio founded in 2006 by Japanese artist Hiro Kamigaki. The studio is known for its highly detailed, hand-drawn visual style, characterized by dense architectural environments, maze-like compositions, humorous background narratives, and bright, pop-art–inspired palettes.
Its best-known creation is the puzzle-book series Pierre the Maze Detective, which has sold more than one million copies and has been translated into over thirty languages. The studio has produced editorial, commercial, and narrative illustration for clients worldwide. Its work has been recognized by major illustration and design bodies, including American Illustration, the Society of Illustrators, and the Art Directors Club of New York.
History
Beginnings
IC4DESIGN traces its origins to 1998, when Hiroshima-born illustrator Hirofumi Kamigaki began working independently after deciding to pursue original illustration and creative autonomy. He had previously worked in a videogame design firm where he felt his work was derivative, and later worked at a design firm and an advertising agency. As a freelancer he began taking commissions from his apartment. His early years were marked by limited business knowledge and the difficulty of client outreach before widespread internet use, an experience he later described as formative in developing both persistence and a willingness to seek work proactively.Founding
Kamigaki formally established IC4DESIGN in Hiroshima in 2006 as a small studio of illustrators working across editorial, commercial, and narrative projects. From the outset, the studio cultivated a collaborative production process involving shared sketching, iterative refinement, and multilayered hand-drawn detail, with some projects requiring years to complete. The group quickly became known for densely composed cityscapes and pop-art–influenced visual storytelling, attracting both domestic and international assignments.International expansion
IC4DESIGN’s early expansion into overseas markets was driven by Kamigaki’s direct outreach: beginning in late 2008, he sent nearly one thousand emails and made about five hundred calls abroad in an effort to secure international representation. This effort landed him a New York agent and, in 2009, a breakthrough commission for the cover of The New York Times Magazine. Although the cover did not immediately raise the studio’s domestic profile, it increased international visibility, and established a foundation for further overseas work. Kamigaki later reflected that working from Hiroshima made pitching to Tokyo and New York feel equally accessible, and the success encouraged him to expand the studio’s global ambitions. Kamigaki and colleague Daisuke Matsubara also cited the 2010 Amtrak National Train Day poster as a formative milestone; selected for the U.S. competition without leaving Hiroshima.By the mid-2010s, IC4DESIGN had gained global recognition and had completed notable commissions from multiple international clients. The release of Pierre the Maze Detective in 2014 further broadened the studio’s audience; the picture book’s elaborate maze-based illustrations were widely exhibited, translated into multiple languages, and contributed to the studio’s growing international reputation. Subsequent volumes extended the series’ reach, with translations into more than 30 languages.
Domestic work and reception
IC4DESIGN’s growing international presence in the late 2000s and 2010s paralleled its continued engagement with domestic clients. Its expanding overseas portfolio boosted commissions within Japan—particularly from Tokyo—and contributed to Kamigaki’s acceptance into the Tokyo Illustrators Society, a form of “re-imported” recognition that he has noted is especially valued by Japanese audiences. At the same time, the studio’s work became widely recognizable in its home city of Hiroshima, appearing across schools, real-estate firms, and other local businesses.Studio
Artistic style
The studio’s style is defined by extremely dense, colorful, and whimsical cityscapes filled with humorous micro-narratives and hidden details. The deliberate and playful visual density and micro-narratives are designed to reward sustained viewing.Their visual language draws clear inspiration from search-and-find traditions such as Where's Wally?, adapting the format into elaborate maze-based scenes that combine storytelling with puzzles. Kamigaki describes the studio’s signature extreme density as a strategic response to the intense competition he faced in overseas markets; producing images that viewers could study “for minutes, not seconds”—a challenge given to him by The New York Times Magazine art director Arem Duplessis— became a defining principle of IC4DESIGN’s aesthetic.
Methodology
IC4DESIGN’s work is grounded in research-driven planning and a meticulous and collaborative production process. When designs are based on real locations, the studio develops illustrations through extensive reference gathering—including photographs, maps, and studies of urban space and local detail—which inform both spatial composition and narrative layering. Projects typically progress through multiple stages, from rough sketches to detailed linework and final color, with some works requiring years of refinement; the production of the first volume of Pierre the Maze Detective, for example, took more than two years to complete.Work is produced collaboratively, with team members contributing to planning, detailing, and execution.
Team and culture
IC4DESIGN is led by illustrator Hiro Kamigaki alongside longtime collaborator and art director Daisuke Matsubara, forming the core of a Hiroshima-based collective with a collaborative approach to illustration. Other team members include Yoko Sugi, Arisa Imamura, Masami Tatsugawa, Keiko Kamigaki, Liang Xiaoming, and later Yujiro Ayano. The studio has cultivated an internally cohesive, family-like working environment, where shared creativity and mutual support shape both daily routines and long-term projects. The team culture combines enjoyment, ambition, and openness to the world.Notable projects
Editorial and commercial projects
IC4DESIGN has built a portfolio of editorial and commercial illustration spanning Asia, the Americas, Europe, and the Middle East. The studio has produced magazine, campaign, and event imagery for clients including Mercedes-Benz, the NFL, Ford, Ogilvy Italy, Adobe Systems, Newsweek, Toyota, Google, Mazda, the Los Angeles Times, and institutions such as the Howard Hughes Medical Institute. Some notable projects include the following.- The New York Times Magazine :The studio’s international reach is closely tied to Hiro Kamigaki’s breakthrough 14 June 2009 "Infrastructure" cover for The New York Times Magazine, commissioned after he shifted his focus from Tokyo to New York and began pitching overseas clients directly. Art director Arem Duplessis asked him to create an illustration so detailed that readers would look at it for minutes rather than seconds, feedback that helped crystallize IC4DESIGN’s highly dense visual style and led to further work for foreign clients. The cover later received industry recognition and became a recurring reference point in media coverage of Kamigaki’s career.
- Amtrak's National Train Day : One of the studio’s subsequent prominent commercial commissions is its work for Amtrak’s “National Train Day” in the United States. Kamigaki and art director Daisuke Matsubara were selected for the project through a major U.S. competition without leaving Hiroshima, then spent two weeks working almost around the clock to complete a large-scale illustration featuring dense crowds, architecture, and rolling stock. The resulting poster, which appeared at more than 180 locations across the country, was described by the Tokyo Illustrators Society as “classic, meticulous illustration” whose scale and quality were comparable to a Japanese Railways-level commission in Japan. Kamigaki later called National Train Day one of his most memorable projects since 1998, crediting it with reshaping his outlook on what a Hiroshima-based studio could accomplish internationally even if it did not immediately transform his day-to-day life.
- UN Women Egypt : The studio also worked on an advocacy project with UN Women in Egypt; a campaign named “Finding Her” created with marketing agency DDB Dubai. The three-piece series, inspired by Where’s Waldo?, depicts cross-sections of a space station, a parliamentary hall, and a scientific research facility, each teeming with male figures but hiding just one woman in the scene. The visuals highlight women’s underrepresentation in Egypt’s emerging sectors of technology, politics, and science, where female workforce participation stood at 23 percent. It was published in multiple Egyptian magazines, and was popular on social media. It was later selected by UN Women as an official global initiative promoting women’s participation in the workplace. It earned a Gold Award at the 2017 Dubai Lynx festival.National Gallery of Bulgaria : In Europe, IC4DESIGN created “The Maze of Sofia,” a large-scale cultural project presented at Bulgaria’s National Gallery. The project presents imaginary labyrinths inspired by the city of Sofia, blending Bulgarian motifs—superheroes, kukeri, rose pickers, and other figures—into Kamigaki’s maze-like urban panoramas. Visitors were invited to navigate the illustrated city with a metaphorical magnifying glass, searching for clues, solving hidden challenges, and engaging in observation exercises reminiscent of the studio’s maze-book work. According to the National Gallery, Kamigaki developed the project through extensive research using photographs, satellite images, urban plans, and studies of local customs. He first created a colorful, utopian version of Sofia in 2021, then visited the city in 2022 and, together with IC4DESIGN, produced a more accurate black-and-white map incorporating textual elements.
The studio has also undertaken projects for global media and technology platforms. IC4DESIGN contributed illustration assets for Google Hangouts emoji design and produced a special Oscars-day wrap cover for the Los Angeles Times, applying its character-dense visual approach to entertainment coverage. In collaboration with Adobe, Kamigaki developed designs for the 2023 Adobe Stock trend “Retro Active,” drawing on 1990s-inspired visual motifs consistent with themes explored in earlier work. For this project, the studio created complete illustrated scenes that were then separated into modular components for reuse within Adobe’s asset marketplace.
In addition to commercial and media-oriented work, IC4DESIGN has accepted commissions from religious and community institutions. During the COVID-19 pandemic, Kamigaki collaborated with Senkoji Temple in Onomichi to create and donate the “Senkoji Temple Illustration,” a detailed image intended to support community morale during a period of restricted travel and public gathering. The illustration incorporates references to local history, films, and events associated with Onomichi and the temple itself, reflecting the studio’s practice of embedding layered cultural detail within its compositions.
''Pierre the Maze Detective'' book series
Kamigaki’s most internationally recognized creation is the puzzle-book series Pierre the Maze Detective, developed with his team at IC4DESIGN. Each volume features sprawling double-page maze illustrations rendered as densely populated cityscapes, fantastical worlds, and interconnected visual narratives. The stories follow the young detective Pierre and his companion Carmen as they pursue the thief Mr. X, whose magical contraptions transform ordinary environments into labyrinths. Each scene includes a characteristic blend of figurative labyrinths, hidden objects, and whimsical details, including animals, ninjas, and futuristic elements.Since the publication of the first volume Detective Pierre Solves the Case, the series has sold over a million copies and has been translated into over thirty languages. The franchise has expanded into multiple activity books, merchandise lines, and a video-game adaptation.
The first volume took over two years to complete. A Hiroshima exhibition presented the full workflow, which showed the project going from rough thumbnail sketches to final linework and coloring, highlighting the intensive work required for each scene.
The video-game adaptation, Labyrinth City: Pierre the Maze Detective, further expanded the series’ reach. Developed by French studio Darjeeling, the game animates environments directly based on artwork drawn by Kamigaki and IC4DESIGN. Players control Pierre as he searches for Mr. X across elaborate, hand-drawn scenes, turning the books’ intricate worlds into explorable digital spaces. The game won multiple awards.
Kamigaki has stated his intention to publish five or six volumes during his lifetime.
Kamigaki also notes that the global popularity of the series increased his domestic visibility and contributed to what he calls the “third phase” of his career. This is marked by frequent approaches from major international brands and an expansion of his creative goals beyond illustration into a wider range of creative projects, including exhibitions and narrative projects. Reflecting on the series’ worldwide reception, he expressed pride that a project born in Hiroshima now reaches audiences around the globe.

Exhibitions
Hiroshima
IC4DESIGN also featured in exhibitions in its home city of Hiroshima.In May 2010, IC4DESIGN opened its first solo exhibition, "Line den City", at Gallery G in Hiroshima. The show featured a mix of commercial and personal works by Kamigaki, including his 2009 New York Times Magazine "Infrastructure" cover illustration and the artwork created for Amtrak's 2010 National Train Day campaign. Displayed as large-format, unframed prints for an informal presentation, the works encouraged visitors to explore the “gimmicks” and hidden details characteristic of IC4DESIGN’s style. Kamigaki remarked that the attention brought a sense of pressure, but he hoped audiences would enjoy discovering the playfulness embedded in each piece.
A 2014 showcase of the production process behind Maze Detective Pierre presented the complete workflow behind the first book, from rough thumbnails to final linework and color. The exhibition displayed the intricately detailed illustrations on large panels and emphasized the two years and three months required to complete the volume. Kamigaki says the finished book feels like his own art collection.
Bulgaria
In 2023, IC4DESIGN presented Sofia’s Labyrinth at the National Gallery’s Kvadrat 500 in Sofia. The exhibition introduced a maze-based illustrated city inspired by the Bulgarian capital, inviting visitors—particularly children—to navigate large-scale works combining Kamigaki’s dense, labyrinthine style with locally inflected imagery. The illustrated scenes incorporated Bulgarian cultural references such as superheroes, kukeri, and rose pickers, and were designed around hidden objects, route-finding tasks, and small narrative challenges.According to the National Gallery, the exhibition materials were developed through a combination of advance research and subsequent on-site study, resulting in both colorful and black-and-white versions of the illustrated city that blend fictionalized space with observed urban detail. During the exhibition period, the National Gallery also organized children’s educational programs connected to Kamigaki’s work and the maze-based format.
