Foldable Phones Go Mainstream: Galaxy Z Flip 5G Lands in Japan

Samsung put the Galaxy Z Flip 5G on sale in Japan this past week (Nov 4), and it’s worth pausing on just how quickly foldables have gone from “weird prototype at a trade show” to “thing you can actually walk into a carrier store and buy.” The Flip 5G now sits next to the Galaxy Z Fold2 in Samsung’s lineup, which means Japanese buyers have two very different takes on folding glass to choose from: the clamshell compact and the tablet-that-becomes-a-phone.

That’s notable because Japan is a famously picky, famously mature smartphone market. It’s not a place manufacturers dump experimental hardware just to see what sticks — carriers and consumers there tend to demand polish. Samsung betting on a second foldable SKU in that market says something about how confident it’s gotten in the category, or at least how badly it wants a new hook to sell premium phones.

Why foldables, why now

The flagship smartphone formula has been stuck for a few years: slightly better camera, slightly faster chip, maybe a new color. None of that is enough to make people upgrade every year anymore, and manufacturers know it. Foldable screens are the first genuinely new form factor since the original iPhone popularized the slab, and that’s exactly why Samsung, and reportedly others eyeing the space, are pushing so hard on it. If you can convince people a folding screen is a must-have rather than a novelty, you’ve got a fresh upgrade cycle on your hands.

The Z Flip in particular is the more approachable of Samsung’s two foldables. It closes down into a compact square, which taps into a nostalgia a lot of us have for flip phones without actually giving up a modern touchscreen experience — you get the big display when you need it and a pocketable little brick when you don’t. The Fold2, on the other hand, is chasing something different: a phone that unfolds into something closer to a small tablet, aimed at people who want more screen real estate for multitasking or media.

Adding 5G to the Flip is also a sign of where Samsung sees this segment heading — not just “foldable as gimmick” but “foldable as flagship,” complete with all the same connectivity bragging rights as their non-folding top-tier phones.

The bigger question

The real test isn’t whether Samsung can ship these phones — it’s whether the hinge and the folding display hold up over months of daily folding and pocketing, and whether enough buyers decide the novelty is worth the premium price tag foldables still carry. Early foldables from a couple of years back had a rocky reputation on durability, and Samsung has clearly worked to shore that up with each generation. Landing in a market as demanding as Japan, with a second foldable model now in the mix, is as good a signal as any that the company thinks it’s cracked the formula. Whether other manufacturers follow with their own foldable pushes in the coming months will say a lot about whether this is truly the next form factor or just Samsung’s pet project for now.
