A Switch 1 rhythm game somehow becomes one of the biggest physical launches of the year, and it's dragging Switch 2 hardware sales up with it.
Nintendo just had a week that nobody saw coming, and the numbers prove it. According to the latest Famitsu sales charts, tracked by Install Base Forum, Rhythm Heaven Groove absolutely dominated the physical charts in Japan, moving 393,378 copies in its debut week.
That's a staggering number for a game that wasn't expected to hit anywhere near this level, and it instantly makes Rhythm Heaven Groove the standout story of the week. Behind it sat Goemon's Great Gathering!, a title with a name so long it barely fits on the chart, which managed 60,428 copies.
Rounding out the rest of the top ten were Tomodachi Life: Living the Dream, Power Pros 2026-2027, Star Fox, a PS5 version of the Goemon title,Pokémon Pokopia. Mario Kart World, eFootball Kickoff, and Minecraft on Switch 2. Solid numbers across the board, but none of them came close to touching what Rhythm Heaven Groove pulled off.
On the hardware side, Switch 2 sold 32,797 units, a noticeable jump from the roughly 24,000 units it moved the week before. It's hard not to connect that bump to Rhythm Heaven Groove's launch, even though the game itself runs on Switch 1.
You'd guess plenty of buyers used it as an excuse to finally pick up a Switch 2 alongside it, maybe bundling it with something else while they were at it. Switch 2 is now closing in on the six million mark in Japan alone, which is an impressive pace for the system this early on.
Switch 2's own numbers tell a similar story of quiet momentum building elsewhere in the chart.
PS5 followed with 10,913 units, Switch 1 sold 10,788, and XBOX Series moved 730 units, which sounds tiny but is actually double what it managed previously. That kind of jump is worth noting even if the overall number still lags far behind everyone else.
What makes Rhythm Heaven Groove's performance even more impressive is how it stacks up historically. Game Data Library put together a comparison showing Rhythm Heaven Groove selling more than double what Rhythm Heaven Megamix did on 3DS. And that's just physical sales in Japan alone.
Once you factor in digital sales and the rest of the world, you're realistically looking at millions of copies for a game that almost certainly didn't cost Nintendo anywhere near what its bigger titles do. The price point alone tells you this wasn't built with a Tears of the Kingdom or Star Fox-sized budget behind it.
This is exactly the kind of release Nintendo depends on. Games like Rhythm Heaven Groove generate serious profit at a relatively low production cost, and that profit ends up helping fund projects that don't sell nearly as well. Metroid Prime 4 is a good example, clearly an expensive game to produce, but not one that's setting sales records.
That production-cost math also explains why Nintendo keeps betting on physical media in the first place.
Rhythm Heaven Groove balances that out, and it's part of why Nintendo can keep greenlighting ambitious, costly titles without worrying too much about the ones that underperform. There's also a bigger takeaway here about physical media.
Nearly 400,000 physical copies sold in a single week is a strong signal that Nintendo isn't backing away from physical releases anytime soon, even as Sony and Microsoft continue hinting they're moving in that direction for their next generation of hardware.
Nintendo seems far more committed to keeping physical games alive at retail, and results like this only reinforce that stance. It's possible file sizes eventually grow large enough that Nintendo has to lean harder into Game-Key Cards, maybe a decade from now with the next console generation. But even then, Game-Key Cards would likely be preferable to ditching physical formats altogether or switching to a code-in-a-box model.
You can still resell or trade a Game-Key Card, and it still holds a spot on store shelves, including in the used section, where it can help new players stumble onto franchises they'd never have tried otherwise. That's very on-brand for Nintendo, a company that's always played the long game, building lifelong fans instead of chasing short-term wins.
