What’s a good Japanese infotainment show about inflation, compounding growth, and NISA?

I’m looking for ways to encourage my Japanese boyfriend to dive into financial literacy now that he’s graduated and started working. I’d love to find an infotainment show, ideally a Japanese one, that covers the basics: inflation, why keeping all your cash in savings might not be the best move, the power of compounding growth, low-cost index funds, and how NISA and iDeCo work.

Does anyone have any good recommendations?
