I believe QR codes are mostly intended to replace paper/magnetic single-ride tickets, not IC cards, in most transit systems.
Magnetic tickets are already slower than IC cards, and are both more expensive to produce and harder to recycle than QR codes printed on regular paper.
Not only more expensive to produce and recycle, but the gates have to be extremely complex to handle paper tickets (some railway museums in Japan have them cross-cut on display!).
I’ve only used them twice (on Sinkansen, and on a regular train in Hokkaido), and it was nearly instantaneous – about as fast as an IC card. The whole experience felt like magic: you put the tichets into a slot, whoosh! – and you pick them up on the other side.
It is true that they are expensive to produce and hard to recycle, though, so it’s a good idea overall. But I’ll miss this iconic experience (or hopefully they retain it on some lines at least). (Edit: or just make the whoosh! readers work with QR codes! :)
That is quite interesting. I took normal-speed medium-distance trains in Taiwan and there are many similarities to Japan. The ticket-checking gates to enter/exit the station are exactly the same models used in Japan. The tickets are similar to the ones used in Japan, but they have a QR Code printed on them and might not be magnetic. Even when you exit the station, the ticket gate will give back your ticket - unlike Japan!
I hope it lasts, but I'm seeing gates which have QR code readers, IC card readers,and contactless payment readers, which is obviously unsustainable. One or more of these will have to give eventually, and given Japan's tolerance for QR code payments (PayPay is massive) and foreigners' familiarity with contactless it seems like IC is the most likely one to go.
I'd be sad if they do go or get relegated to some app, I love the little mascots.
A perfectly aligned QR code, displayed on a bright mobile phone display, can work acceptably fast.
Practically, many people however only start thinking about possibly needing to open some app to display it while they’re already blocking everybody else’s way at the transit gate…
The biggest practical benefit of IC cards is that they are by nature always “armed”, unlike QR codes in apps, and are readable from both sides.
On top of that, due to being able to run mutual authentication and being able to store a trusted balance, they are much more resilient to outages of any backend system. QR code tickets invariably need networking and a central backend.

>It will continue to accept national IC cards such as Suica and Icoca

Some are cutting back to just Suica and Icoca. Some are switching to, or using from the start, tap-and-pay (Visa, EMV, etc.).

so there's that, I mean if we can optimize QR code system. the winner obviously would be QR because no need to have an dedicated hardware for this
Yes, IC card would be faster but at what point the difference is matters???
