"Japanese shares are seen moving in a narrow range after a mixed close in the US market," senior market analyst Toshiyuki Kanayama said in a commentary.
Ray Attrill, senior strategist at National Australia Bank, noted that US President Joe Biden had walked back a threat over a bipartisan infrastructure bill.
As "one of the catalysts for US equities achieving new record highs last week was the news of... the handshake deal," Biden's apparent threat could "be one source of market volatility in the week ahead," he added.
Investors are awaiting fresh clues for trade, including US ISM manufacturing purchasing managers index and US payrolls data due later this week, analysts said.
