The Core Question

What makes Mabuchi Motor Co., Ltd. worth investigating? The preliminary screening data suggests a A-quality Japanese business with a wide moat in scale + cost leadership. The key question for full analysis: is this moat truly durable over a 10-20 year horizon?

Moat Meditation

50%+ global market share in small motors. 70% of automotive mirror motors worldwide. Family-owned with strong corporate culture. Scale moat from massive production volumes and cost leadership.

The durability of this moat needs rigorous testing through full analysis. Japanese manufacturing companies often have deeper moats than their financial metrics suggest - decades of accumulated know-how, supplier relationships, and quality culture create barriers that are difficult to replicate.

At ¥4,000, the stock trades +14% above the accumulate price of ¥3,500. Patience is required. The entry discipline of waiting for ¥3,500 (Accumulate) or ¥3,000 (Strong Buy) must be maintained.
