Japan's Nikkei 225 index fell sharply on Thursday, dropping more than 3% to 66,612.63 in late-morning trading.

72% to 67,763, weighed down by technology stocks that mirrored a wider selloff in US tech-heavy indices.
The move marks a significant acceleration in selling pressure across Asian markets.
The index had already suffered a steep 3.8% decline over the previous trading week, closing in negative territory amid broader regional risk-off sentiment.
Wednesday's session saw the index fall 0.72% to 67,763, weighed down by technology stocks that mirrored a wider selloff in US tech-heavy indices.
Thursday's drop extends that trend, signaling that investor caution toward high-multiple growth names remains acute.
