$JP225 +4.0% today — what's driving it?

This is a big move. Seems like some positive sentiment around corporate governance reforms and renewed focus on shareholder returns could be contributing.

This move on the Nikkei seems largely disconnected from any significant news. Could be a short squeeze, or just momentum playing out. I wouldn't rush to get in on this, feels a bit overheated for now.

It's interesting to see such a strong move. I'm wondering if this is a delayed reaction to recent global economic data or if there's a specific catalyst unfolding today that I've missed. What are others seeing as the primary driver?

The Nikkei's been on a tear lately, so it's not entirely surprising to see another strong day. I'm curious if this move is primarily domestic optimism or if there are external factors at play, especially with the global economic picture being a bit mixed.
