Tachikawa was born in Yokohama, Japan. He studied architecture at Hosei University, graduating from its Faculty of Engineering in 2004. He subsequently studied at the Graduate School of Science and Technology at Keio University, completing his master's degree in 2006. While studying architecture, Tachikawa began working under the name NOSIGNER in 2006. His practice developed across multiple disciplines, including product design, graphic design, branding, architecture and spatial design.

Following the 2011 Tōhoku earthquake and tsunami, Tachikawa initiated OLIVE, an open-source platform for sharing practical knowledge and design ideas for people affected by disasters. The project collected and distributed information on improvised tools, shelters and other techniques that could be used in emergency situations. In 2015, Tachikawa and NOSIGNER worked on Tokyo Bousai (Tokyo Disaster Preparedness), a disaster-preparedness manual commissioned by the Tokyo Metropolitan Government. Tachikawa was involved in the project's art direction, graphic design and editing. The project received the Good Design Gold Award in 2016. His later work has included ADAPTMENT, a design framework addressing climate-change adaptation through approaches inspired by biological evolution and ecosystem resilience.

In 2014, Tachikawa served as concept director for the Japanese government's Cool Japan Movement Promotion Conference. From 2020, he participated as a creator in developing the basic concept for the Japan Pavilion at Expo 2025 in Osaka, Kansai. In 2021, Tachikawa became president of the Japan Industrial Design Association (JIDA), serving until 2025. During this period, Tokyo hosted the World Design Assembly 2023, the first WDO General Assembly held in Japan in 34 years. Tachikawa was elected to the WDO Board of Directors for the 2023–2025 term. During the term, he served as chair of the Membership Committee and vice-chair of the Programmes Committee. At the World Design Congress in London in 2025, he was re-elected to the WDO Board for the 2025–2027 term.

Tachikawa developed Evolutional Creativity, a methodology that applies principles inspired by biological evolution to creative thinking and design education. The approach distinguishes between processes analogous to mutation and selection and uses observation of natural and social systems as a framework for developing ideas. He began developing the methodology in 2016. In 2021, Tachikawa published the Japanese-language book Shinka Shikō: Ikinokoru Concept o Tsukuru "Hen'i to Tekiō" (進化思考 生き残るコンセプトをつくる「変異と適応」), presenting the methodology in book form. The book received the 30th Yamamoto Shichihei Prize in 2021. A revised and expanded edition, supervised from a biological perspective by evolutionary biologist Masakado Kawata of Tohoku University, was published in 2023. The methodology has subsequently been introduced in companies and educational institutions and the book has been translated into Chinese, Korean and Indonesian. In 2023, Tachikawa presented a paper, "Evolutional Creativity: Evolutionary Principles for Creative Learning", at the WDO Research and Education Forum in Tokyo.

Tachikawa has taught design and innovation at universities in Japan and internationally. He became a project professor at the Graduate School of System Design and Management at Keio University in 2024. His international educational activities have included collaborations with the Bandung Institute of Technology (ITB) in Indonesia. In recognition of his contribution to making academic activities at ITB more transdisciplinary, innovative and socially impactful, the university awarded Tachikawa the Ganesa Widya Jasa Adiutama award.
