[Dec 4, 2025 Tokyo Market Audio Commentary] The 'Physical AI' Market That Shook Off the Gravity of 1.9% Interest Rates

December 4, 2025. Looking back, this day in the Tokyo market may be remembered as a 'historical turning point'.

The Nikkei Stock Average rose by over 1,100 yen, and the TOPIX hit a new all-time high during trading hours.

However, did you notice what was happening behind the scenes?

In fact, long-term interest rates had reached the 1.9% level, their highest point in about 18 years.

According to economic textbooks, 'rising interest rates' should mean 'falling stock prices.' Yet, the market completely ignored that gravity and soared like a rocket.

What exactly were investors so excited about?

To unravel that answer, I created a podcast using Google's AI 'NotebookLM' to ingest the day's news videos and market data for a deep-dive analysis.

The conclusion reached by the AI analysts was surprising.

It is the arrival of a new wave called 'Physical AI' (AI with embodiment).

Highlights of the audio commentary (approx. 13 minutes)

・Why was the negative factor of rising interest rates ignored?

・The surge in 'robot-related stocks (FANUC, Yaskawa Electric)' that drove the market.

・The 'AI Boom Chapter 2' scenario ignited by U.S. government reports.

・An unexpected perspective? Changes in consumption seen in McDonald's price hikes and the 'value' of MOS Burger.

The AIs discuss the market's contradictions and excitement just like humans, sometimes excitedly and sometimes calmly.

Whether you are commuting or using this as background music while working, please feel the heat of this 'Physical AI market'.

If you listen to this podcast, you should be able to see that a massive story is moving behind what were once just lists of stock price numbers.
