Japan this morning looks like a country pulling in several directions at once. The yen keeps slipping — past 162 to the dollar, a level not seen in nearly four decades — while IPO activity has cooled to its weakest in 15 years, partly because startups around AI, data centers, and semiconductors are still thin on the ground here. Against that macro backdrop, capital is quietly concentrating in biotech (kidney, silk-protein healthcare), engineers are pushing security and observability standards forward, and the government is reshaping the imperial family with a once-in-a-generation legal change. I read today’s mix as institutions adapting — fast in some places, slow in others — to a yen-weak, capital-scarce, but still inventive Japan.
