Japanese equities rallied on Wednesday as investor anticipation grew over a potential snap election, being considered by Prime Minister Sanae Takaichi.

The Nikkei 225 rose 278.1 points or 0.5% to open at 53,827.24.

The gains occurred despite a slide in U.S. markets, with local investors largely ignoring inflation data that reinforced expectations for a U.S. Fed pause on rate hikes.

Meanwhile, major U.S. banks are scheduled to release their earnings later in the week.

Traders also remained watchful on an impending U.S. Supreme Court ruling on White House tariffs.
