The Nikkei 225 fell 0.7% to below 53,500, while the broader Topix Index also dropped 0.7% to 3,626 on Friday, extending losses from the previous session amid a tech-led selloff on Wall Street.
Concerns over massive artificial intelligence spending and potential disruption to software companies drove the decline.
A broader selloff in metals and cryptocurrencies further weighed on risk sentiment, reflecting widespread deleveraging across financial markets.
Technology stocks led the losses in Japan, with Kioxia Holdings down 5.6%, SoftBank Group falling 1.7%, and Advantest sliding 3.5%.
Consumer and financial firms also came under pressure, including Nintendo (-3.7%) and Mitsubishi UFJ (-1.8%).
Investors are also eyeing this weekend's lower house elections, where the ruling LDP is expected to gain seats and pursue expansionary fiscal policies under Prime Minister Sane Takaichi.
