Japanese architecture studio I-IN demonstrates its exceptional command of contemporary minimalism in a stunning new book by Frame Publishers. The publication captures the essence of the firm’s design philosophy, blending sleek modernity with Japan’s rich cultural heritage.
One standout project featured in the book is the Cartier Guest Lounge in Tokyo, a space that embodies luxurious restraint. Captured beautifully by photographer Tomooki Kengaku, the lounge reflects I-IN’s ability to craft environments that are both sophisticated and inviting.
A Deep Dive into I-IN’s Design Philosophy
Founded in 2018 by partners Yohei Terui and Hiromu Yuyama, I-IN has quickly established itself as a leader in minimalist architecture. The studio’s diverse portfolio ranges from futuristic office spaces to serene retail interiors, all unified by a meticulous attention to detail.
The newly released book, aptly titled I-IN, includes an insightful essay by Daven Wu, Wallpaper’s Singapore editor, offering readers an in-depth look at the studio’s creative process. Through a series of case studies, the book highlights I-IN’s ability to merge innovation with timeless simplicity.
Notable Projects: Where Tradition Meets Modernity
1. Kinujo Headquarters – A Study in Subtle Elegance
Located in Tokyo, the Kinujo office (photographed by Ooki Jingu) is a masterclass in understated design. I-IN’s use of clean lines and natural materials creates a workspace that feels both functional and serene.
2. Warp Studio Office – Futuristic Yet Warm
The Warp Studio project showcases I-IN’s talent for balancing futuristic aesthetics with human-centric design. White walls, expansive glass windows, and warm wooden accents define this innovative workspace.
3. Cartier Guest Lounge – Luxurious Minimalism
The Cartier lounge exemplifies I-IN’s ability to craft spaces that feel exclusive yet welcoming. Soft curves, refined textures, and a muted color palette create an atmosphere of understated luxury.
Why I-IN’s Minimalism Stands Out
Unlike stark, cold minimalism, I-IN’s designs exude warmth and approachability. The studio’s expert use of textures, curves, and natural materials ensures that each space feels intentional and lived-in.
As Daven Wu notes in the book’s introduction, many architects strive for a signature style early in their careers. However, I-IN defies this trend—instead of relying on obvious visual trademarks, the studio focuses on thoughtful, adaptable design.
Wu writes:
“For I-IN and its founders, there are no overt markers that make one instantly recognize their work. Instead, it’s their quiet thoughtfulness, clarity, and flexibility that define each project.”
A Rising Force in Architecture
With each new commission, I-IN reinforces its reputation as a studio that prioritizes meaningful, human-centered design. Their work doesn’t shout for attention—it invites contemplation, proving that true minimalism is about substance, not just style.
For those eager to explore I-IN’s architectural vision further, Frame Publishers’ new book is a must-read. It’s a celebration of Japanese design at its finest, where tradition and modernity coexist in perfect harmony.
