Simply Wall St · 2d ago

Tokyo inflation just hit 2.7% in September, and the Bank of Japan is openly weighing rate hikes for the first time in years. Big institutions tend to focus on large, well covered Japanese stocks when policy shifts like this occur. That leaves a pocket of smaller, high quality companies going largely ignored. This article highlights three such under the radar Japanese opportunities from our screen that may be worth a closer look.

The three stocks covered next are just a sample set from this theme, and the full screen surfaced 72 more businesses with equally compelling narratives that are not covered here. To go straight to the source and identify your own high conviction ideas, head into the High-Quality Undiscovered Gems screener.
