The Nikkei index reversed its course, closing lower on Friday due to caution ahead of the Bank of Japan's monetary policy meeting, while the yen's rise against the dollar prompted investors to sell stocks. The Nikkei fell by 0.09% at the close, retreating from a 1% jump earlier in the session. The index remained stable throughout the week.
The broader Topix index also reversed its trend, declining by 0.17% and losing 0.7% over the week.
The yen simultaneously rose to reach a two-month high of 137.245 to the dollar earlier in the session.
SoftBank Group's share fell by 2%. Gains in stocks of companies linked to chips limited the Nikkei's decline after Advantest's shares for semiconductor testing equipment jumped by 5.74%, while Tokyo Electron's shares for semiconductor manufacturing equipment gained by 1.76%.
