The OP has now mentioned that this is for the games "industry", and indeed for a VR, indeed console, shop, which is two years old.
Dressing for the games industry can, in extreme cases, be a minefield...it's an interesting topic.
Many small (but relatively incredibly successful) companies are started by a few guys who got lucky with an app, made literally millions, drive Ferraris, and then for the first year or two after that (likely foolishly) think they can start a "company" and duplicate the success.
In that case you may have to dress and look like Joe Walsh, "Notch", or the like. The I'm-a-badass-genius "rich-but-ratty" look.
Bear in mind that it's not impossible, you will walk in to a shop like that.
In other cases, remembering that amongst the technically difficult parts of game engineering, it's the hardest software engineering ... so you may want to look like one of those mathematician geniuses in a Spielberg movie who knows what tensors are. Wear a totally unassuming short-sleeve work shirt, type of thing. You're all brain.
The "console industry", at least in Japan, is personality-driven, so the folks you're going to meet see themselves as and look towards this sort of guy.
How would you dress to interview with Itagaki?

Excellent short reference article (a little dated) on the personal style of the famous console programmers in Japan.
{Aside, for an excellent insight in to the Japanese game scene and the personality cult thereof, in English, watch the otherwise rather hokey "imagine-nation" on NHKTv, which is freely available online at nhk.or.jp.}
VR! At the time of writing, VR defines frothy and bubbly. It's the latest fad in a fad-driven business.
{If you're reading this in a few years you'll be saying "oh, that was that 'headset thing' right?"}
It's possible that if they've had success with a VR title or a contract, they see things as pretty rosy and bubbly, and things are pretty rosy and bubbly.
Given all this and particularly that the guy actually explicitly mentioned it to you, there is a real chance that you'll walk in and find the sort of shop where the principals have fancy cars, everyone looks "creative", and the slighty rock-star "rich but ratty" look is going on.
It's the kind of "skater-successful-programmer" look - you know?
So don't worry about it but be aware you may run in to folks who think they are, and who indeed are, pretty "cool" - after all, it sounds like it's a successful "VR" shop and that's the single bubbliest, frothiest thing at the moment.
Do not go overboard trying to be or look cool. If you have a "cool t-shirt" that you've had awhile (not a new one you went out and bought so as to be cool), wear that.
Remember that understated always works and is safe in a "cool" setting. (I feel like I'm writing for GQ.) A completely plain Haines gray tshirt or a ten dollar wrangler button shirt.
If you wear something cool or artistic, like that new commes-des-garcons shirt you just bought, and you don't "pull it off", it's a disaster. (If you can pull it off and you do commonly wear your commes-des-garcons shirt, you're golden.)
As always with clothing, shoes are the most difficult: you can easily "give away" the wrong vibe. Remembering that the theme is a "rich hippy" vibe, a suggestion might be those expensive sports-like sandals popular today (but old, used). But again, only if you're totally comfortable and relaxed in them.
Stepping in to a "cool" situation - if that's what it proves to be, it may just be a few totally "everyday" folks sitting around programming PCs - but there's a real chance it might be - is actually pretty tricky, you have to handle it delicately. Don't forget that understated always works and is safe in a "cool" setting.
(If you are in fact, by coincidence, a skater or surfer or Rasta, you're all set.)
