AI related memory chips are pulling in record profits for giants like Samsung, and that flood of spending on hardware is rippling across supply chains and software in Asia. Smaller Japanese companies tied to automation, data processing, or AI workflows are plugged into this same wave but remain under the radar. This article highlights three compact Japanese AI stocks from our screener that aim to capture exposure to that trend.
The three Japanese AI stocks below are just a starting sample, as the full Simply Wall St screen surfaced 10 more small cap companies with equally compelling narratives that are not covered here.
If you want to go broader and identify your own highest conviction ideas, head straight into the AI Small Caps screener to analyze, compare, and focus on the AI plays that best fit your approach.

Market Cap: ¥78.2 billion
ExaWizards provides exposure to enterprise AI in Japan through productized solutions in areas such as predictive maintenance, process optimization, and healthcare. The group is profitable and focused on real-world deployments rather than unproven concepts. However, its reliance on external funding and board turnover means that potential outcomes may be influenced by factors that are not fully visible to public investors.
That opacity on funding and governance raises key questions about risk and reward, which is exactly what the 2 key rewards and 1 important major warning sign is designed to examine.
