Kai Yokoyama : 横山快
Kai Yokoyama Photographer, Satellite Data Artist & Data Storyteller
Kai Yokoyama is a Tokyo-based photographer and Satellite Data Artist who bridges the gap between scientific truth and overwhelming visual beauty. While his roots lie in architecture and documentary photography, his current practice focuses on "Data Storytelling"—translating intricate satellite observations into powerful narratives that define our relationship with the planet.
A recipient of the LensCulture Journeys Award (1st Place, 2020) and a Carolyn Drake mentee at Magnum Photos (2021), Yokoyama has long operated at the frontlines of visual expression. His work, which has been featured in The Washington Post, Marie Claire Italy, and Foam Magazine, is characterized by a visceral commitment to "Context."
Recently, Yokoyama has evolved his practice to address global environmental challenges. By leveraging AI and multi-spectral satellite data, he creates "The Context Archive"—a series of works that resist the oversimplification of our changing Earth. As a guest contributor for the Sustainable Space Economy (SSE) Initiative, he provides insights into how orbital perspectives can foster corporate responsibility and global ownership.
He is a member of Native Agency and Diversify Photo, and has served as a juror for the ADC 101st Annual Awards. Currently, he is accepting select commissions for ESG visual storytelling and corporate art installations for Q2 2026.
横山 快 写真家 / サテライトデータアーティスト / データストーリーテラー
横山 快は、東京を拠点に活動する写真家であり、科学的な真実と圧倒的な視覚美の融合を追求するサテライトデータアーティストです。建築学（埼玉大学）から写真の世界へと転身し、東京綜合写真専門学校で研鑽を積んだ彼のルーツは、ドキュメンタリーと建築的視点にあります。現在は、複雑な衛星観測データを、地球と私たちの関係性を定義する力強い物語へと翻訳する「データストーリーテリング」を活動の核としています。
2020年にはLensCulture Journeysアワードで1位を獲得、2021年にはマグナム・フォト（Magnum Photos）にてキャロリン・ドレイク氏のメンターシッププログラムを受けるなど、長年、視覚表現の最前線で活動してきました。彼の作品は『The Washington Post』、『Marie Claire Italy』、『Foam Magazine』などの国際的なメディアに掲載され、「Context（文脈）」への深いこだわりを特徴としています。
近年、横山は地球規模の環境課題に取り組むべく、その活動を進化させています。AIとマルチスペクトル衛星データを活用し、変わりゆく地球の姿を過度に単純化することに抗う作品群「The Context Archive」を展開。また、宇宙の持続可能性を追求する「Sustainable Space Economy (SSE) Initiative」のゲストコントリビューターとして、軌道上からの視点がどのように企業の社会的責任やグローバルな当事者意識を育むかについて発信しています。
ADC第101回年次賞（ニューヨーク）の写真部門審査員を務め、Native AgencyおよびDiversify Photoのメンバーとしても活動。現在、2026年第2四半期（4月以降）に向けた企業のESGビジュアライゼーションやオフィスへのアート設置、ブランディングコンサルティングの案件を限定的に受け付けています。
