The Nikkei 225 fell 0.9% to below 43,200, while the broader Topix Index lost 0.3% to 3,107 on Wednesday, extending the previous session's decline and mirroring a tech-led selloff on Wall Street.
US chipmakers and other technology stocks slid overnight in a broad risk-off move.
In Japan, trade data added to the cautious mood, showing exports fell 2.6% year-on-year in July, the steepest drop in over four years as sweeping US tariffs weighed on overseas demand.
Imports also contracted 7.5%, marking the fourth decline this year but beating expectations for a 10.4% fall.
SoftBank Group led the downturn, plunging 7% after a 4% slide in the prior session.
Other major losers included Mitsubishi Heavy (-2.6%), Advantest (-4.4%), Fujikura (-5.5%), Disco (-2.3%), and IHI Corp (-3.9%).
