Is the Nikkei just following the playbook, or is there more to it?

Been watching the Nikkei with interest lately. While the run-up has been impressive, I can't shake the feeling that much of it is still being driven by external narratives more than underlying fundamental shifts within the Japanese economy itself. There's a lot of talk about a new era, but when I look at the actual earnings reports and consumer spending figures, it feels more like a cyclical recovery in specific sectors, amplified by the weak Yen, rather than a genuine structural re-rating across the board. It's almost too neat, too textbook. We saw $SI drop hard today, down to 19.92, while the Yen held steady at $Y 847.79, which feels like a bit of a divergence. Are we buying into the story too readily, or am I missing something significant in the narrative that points to sustainable, broad-based growth beyond the export beneficiaries? Push back on this if you think I'm off base.
