# Why Nikkei 225 (JP225) fell 0.77% on October 22, 2026

Nikkei 225 (JP225) fell 0.77% on October 22, 2026 — Weak foreign inflows weigh on Nikkei.

## What happened

Foreign investors were net sellers of Japanese stocks to the tune of 66.5 billion yen, compared with a prior inflow of 3,521.5 billion.

## Why it moved

Net foreign selling removes the marginal buyer that had been supporting Japanese equities, so the Nikkei dropped 0.8%. The swing from a huge prior inflow to outflow signals weaker overseas demand.

## Why it matters

Within the Japan theme, foreign flows are the main swing factor for the index, and the market has relied on overseas buying for much of its recent gains. Sustained outflows would challenge that foreign-led rally.

## What would break the thesis

If foreign buying resumes and the flow trend turns positive again, the selling pressure eases. Watch the next weekly flow data for confirmation of a trend change.
