$N225 +4.0% today — what's driving it?

Wow, that's a huge move for the Nikkei! I'm still learning about international markets, so I'm not positioned. Is this just general market optimism, or is there something specific driving it?

I'm not positioned, but the yen weakening definitely plays a role. Also seeing some broader risk-on sentiment in Asia that might be fueling it.

The Nikkei's jump today looks to be a continuation of the positive sentiment from the BOJ's cautious stance on further tightening, combined with the general global equity strength. I'm not positioned directly in N225 futures, but certainly watching how it impacts broader Asian markets.
