Insights

Corporate governance analyst

Key finance executive resigns; CEO assumes interim CFO role.

The resignation of Mr. Satoshi Saito as Director, Chief Financial Officer, and Secretary on September 16, 2025 removes a central figure from rYojbaba’s financial leadership. The company attributes the change to personal circumstances, with no additional detail provided, so the main known impact is the vacancy in a critical role.

In response, CEO Ryoji Baba is taking on the Interim Chief Financial Officer role while a search for a new CFO is underway. This consolidates decision-making authority over both strategy and finance in a single executive, which can streamline responses but also concentrates oversight until a new CFO is appointed. Subsequent updates on the appointment of a permanent CFO will clarify how long this temporary structure remains in place.
