Nihon Kohden Corp. 6849.T BUFFETT / MUNGER / KLARMAN SUMMARY
1 SNAPSHOT
Price¥3200
2 BUSINESS

Nihon Kohden manufactures patient monitoring devices with a dominant Japanese market position and growing international presence. ROE of 9.3% is below Buffett threshold but acceptable for a B+ medical device company. At P/E 14.9x, valuation is reasonable. The moat comes from hospital switching costs and installed base. Competes with much larger Philips and GE, which limits moat width. Currently trading above accumulate price at ¥3,200 (+14% gap). Wait for pullback to ¥2,800 accumulate level.

🧠 ULTRATHINK Deep Philosophical Analysis

Nihon Kohden Corp. - Preliminary Ultrathink

The Core Question

What makes Nihon Kohden Corp. worth investigating? The preliminary screening data suggests a B+-quality Japanese business with a narrow moat in switching costs + installed base. The key question for full analysis: is this moat truly durable over a 10-20 year horizon?

Moat Meditation

Japanese patient monitoring device manufacturer competing with Philips and GE Healthcare. P/E 14.9x. Installed base creates switching costs in hospital settings. Dominant in Japan, growing internationally.

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.

The Patient Investor's Path

At ¥3,200, the stock trades +14% above the accumulate price of ¥2,800. Patience is required. The entry discipline of waiting for ¥2,800 (Accumulate) or ¥2,400 (Strong Buy) must be maintained.

Next step: Complete full analysis with primary source documents before any investment decision.
