@PressuredFishing you might like the way the rod page is divided up in the Plat.jp online catalog

Bass fishing is one of 15 niche categories (and a few more categories thrown in for packaged combos, travel rods, rod building). Here's a crop from that page. (You also won't find all these rods in stock, but it's a good way to compare length, style, action, specs)
Of course, they're an island nation, surrounded by the sea, and a thousand-year tradition of taking their food from the sea.
The trick is look at their back yard, what they offer their market, then look at your back yard, whether any of it can help you.
Plus, you'll never have a 20-something Expert at BPS telling you what you need.

Back to that Plat catalog, the biggest advantage you'll likely find in JDM rods is bank fishing, where all their fishing traditions began. Also, their thousand years of shore fishing began with finesse fishing. USM is aimed at major US niches, and even the Japanese export to USM in those same niches - Bass, panfish, trout, salmon/steelhead, inshore, surf, offshore.
While I grew up bass fishing reservoirs, inshore sloughs and jetties with my dad, my 50 years of fishing Texas hill country limestone creeks has mostly been with a fly rod (ok, rods), and river bass are only a slice. Pretty easy to argue fly fishing is our national finesse-fishing tradition.

There's one spot in particular on the "middle" Guadalupe where we sight-fish longnose gar - takes a sharp hook, and they make astounding aerials. Even if you don't hook one, their 10' surface lunge to attack your fly is a rush.
I could go on and on - when we did the math on FFR forum a decade ago, I could list over 100 species caught on fly rod.
Adding a ps - I have several friends on FFR finesse-fishing Sierra Nevada lakes using Japanese Light Game rods - they sourced them from US vendor Bait Finesse Empire, who stocks both USM and JDM tackle.
