Joji Toyama

Graduated from the Department of Systems Innovation, Faculty of Engineering, the University of Tokyo. Graduated from the Department of Technology Management for Innovation, the Graduate School of Engineering, the University of Tokyo (received the Dean’s Award for The Graduate School of Engineering). Since his third year of undergraduate school, he had focused on Deep Learning research at Matsuo Laboratory, and had led many joint research projects with companies as a leader. After joining DeepX, he has been working on automation projects in the area where automation has been difficult to achieve, such as a hydraulic excavator autopilot project. He assumed Director and Chief Development Officer in June, 2019.


Owing to the declining birth rate and aging population, the number of workers in many nations has been on the decrease, and this trend will only continue to intensify in the future. Within Japan, in particular, the preceding Heisei era is regarded as a period of stalled economic growth, while the current Reiwa era stands poised to be a period of outright recession. Labor shortages have already become apparent in various industries, especially those requiring physical activity in sometimes harsh environments and other challenging conditions, such as construction and agriculture, as well as those relying on expert craftsmanship. In the future, new buildings will no longer be constructed, domestic rice will no longer be cultivated, and infrastructure such as gas, water, and roads will no longer be maintained, unless these challenges can be addressed.

The potential to solve this problem lies in the technologies relating to artificial intelligence, which is being pioneered through Deep Learning, and advancing rapidly at this point. Artificial intelligence has already demonstrated a level of performance that exceeds human capabilities in a number of tasks within the software domains of imaging and languages. We endeavor to automate various human movement tasks by further applying this artificial intelligence technology to the domain of hardware, with the ultimate aims of bringing about a productivity revolution in industries where labor shortage is most serious, and playing a key role in supporting the continued development of Japanese industry into the Reiwa era.

In order to achieve this goal, we have gathered a team of relatively young professionals that show outstanding qualities and lofty aspirations – individuals who exhibit a commitment to improving and innovating on a daily basis, working tenaciously and tirelessly, and maintaining problem-solving as their top priority. This team is looking for additional members who will empathize with our mission and deliver the best outcomes for our customers.




  • Understanding the essential issues faced by clients
  • Selecting and designing the best solutions to tackle these issues, including the implementation of advanced artificial intelligence technology
  • Communicating with clients in order to present the benefits of implementation


  • I've been intensely passionate about bouldering for a long time.
    Though there are some people who like bouldering in our company, I was the first one.
    I believe that bouldering is a sport that has helped me grow a lot as an AI engineer and in this regard, I can call the sport “Mother”.
    First of all, bouldering teaches me how important daily efforts are. Bouldering is a sport that relatively depends on muscle mass, so the more you practice, the stronger you become. Though I have played tennis and soccer before, it is a new experience in terms of the fact that I can clearly realise the growth every day. As an AI engineer, day-to-day efforts such as keeping track of papers and organising codes are crucial and the bouldering experience brings in a huge plus to me.
    Also, just like Reinforcement Learning, one of the AI technologies, I think it's important to strengthen ourselves as well as strengthening agents.
    Second, bouldering develops the ability to solve problems by reaching the goal in the shortest possible time. Bouldering is a game where you use a limited number of holds to reach the goal, but the difficulty of reaching the goal varies greatly depending on how you use the holds. By finding the best route quickly, you can get to the goal before fatigue builds up in your body. This helps me improve the essential skill as an AI engineer, which is to understand the essence of the issues and gain the most value with the fewest resources.
    Finally, bouldering tells me how great the cooperation with peers is. Bouldering is basically an individual sport, but people who are challenging the same route naturally have conversations such as this had better be done this way (this is called a session). The effect of the session is enormous.
    When I climb with peers, I will discover the route solution that I would never come up with by myself. This experience has contributed greatly in the occasions when I address the issue together with my peers and discuss various ideas.
    While honoring Mother bouldering, I want to keep climbing the walls of my life as well as the artificial walls.

  • I have been part of a band since I was in high school, and continue to play the guitar. My father has a band of his own as well, which I join for live performances every year or so. It’s a lot of fun, despite the obvious age gap.
