Promotool Appoints New Graduate as Deputy Director of Scent AI Lab

In a notable move toward advancing its AI initiatives, Promotool Inc., based in Bunkyo-ku, Tokyo, announced the appointment of Yoshitaka Okubo, a fresh graduate, as the Deputy Director of the Scent AI Lab effective April 1, 2026. Known for its expertise in scent technology, Promotool is keen on incorporating AI into the fragrance industry, focusing on enhancing productivity and operational efficiency.

Background of Appointment

This strategic hiring aligns with Promotool's broader AI strategy aimed at innovating production processes and enhancing the sophistication of operations within the fragrance sector. Yoshitaka Okubo, despite being a new entrant to the workforce, stands out for his exceptional understanding of AI and analytics, recognized during his time as an intern with the company starting March 2025.

Graduating from Keio University, Okubo specialized in policy studies and engaged in research at the Yahagi Laboratory, where he developed AI models for clinical forecasting. He also completed a course at the Matsuo Laboratory of the University of Tokyo, gaining insight into AI business strategies. His skills were further honed at 42 Tokyo, where he delved into algorithm design and deep learning, underscoring his capabilities in practical efficiency and creativity in operations.

A Vision for the Future

Promotool has continuously maintained high-quality products across areas such as fragrance creation, space design, and OEM development thanks to the expertise of professional staff. However, with growing business demands, the challenge lies in balancing production volume with development speed while still supporting professional judgement. During his internship, Okubo worked on analyzing previously subjective processes and advocated for the standardization and redesign of operations through AI, effectively mitigating human errors and stabilizing operational quality.

The company aims to leverage its rich database of fragrance data—including formulation, sensory evaluation, component analysis, and safety assessments—to build a robust foundation for data-driven decision making, ultimately enhancing both accuracy and speed in the development process.

Innovation at the Core

Okubo's rapid ascent to the role of Deputy Director at the Promotool Scent AI Lab (PSAL) highlights the company’s commitment to merit-based roles, focusing on capabilities and results rather than age or experience. Amidst a global trend where foreign fragrance companies are increasingly deploying AI for olfactory support, Promotool is positioning itself as a pioneering scent technology company from Japan, rapidly integrating AI within fragrance design processes.

The PSAL aims to combine data, sensory evaluations, and chemical knowledge to establish a novel fragrance development model that merges sensitivity and science.

Voices from Leadership

In Okubo's own words, “At Promotool, there’s a culture that allows individuals to take on responsibilities regardless of their years of experience. Through my internship, I realized that I can thrive in an environment where responsibility directly correlates with results. I will continue to focus on enhancing the reproducibility and productivity of our operations through AI, contributing to the creation of new values in fragrance development.”

Promotool's CEO, Kensuke Ogata, commented on the significance of this appointment: “The fragrance industry has developed based on experience and sensitivity over time. However, we are now entering a phase of augmentation through AI and data, rather than replacement. By assigning responsible roles to those who can create value irrespective of their age, we can accelerate the pace of transformation. This hiring is not just about strengthening our workforce; it is a critical step towards implementing our ‘Fragrance x AI’ strategy.”

Looking Ahead

As Promotool continues to champion productivity innovation through AI, the company is committed to enhancing its data foundation that supports professional judgement, improving design precision in fragrance spaces, and optimizing the creation and development processes. The recent hiring represents a pivotal moment in the full-scale deployment of AI within the fragrance industry, marking Promotool's evolution into a next-generation scent technology company that integrates sensitivity, science, and AI.
