Tokyo stocks ended lower Tuesday on dwindling chances of a US stimulus package, as some investors took a wait-and-see approach ahead of the corporate earnings season.
The benchmark Nikkei 225 index lost 0.44% or 104.09 points at 23 567.04, while the broader Topix index fell 0.75% or 12.24 points to 1 625.74.
"Investors are watching the direction of the US talks over the additional economic measures," Okasan Online Securities said in a commentary.
The Tokyo market began the day under pressure after overnight falls on Wall Street.
Bargain-hunters provided some support in the morning but the weakness of other Asian markets placed further weight on Tokyo, especially in the afternoon, Okasan said.
Analysts said the market also lacked fresh cues for major moves.
"In the afternoon session in particular, investors began to take a wait-and-see stance ahead of a corporate earnings season, starting at the end of this month," said Okasan.
The Nikkei index was "directionless", but various factors ended up driving down Tokyo shares, SMBC Nikko Securities added.
