They have some chewing gum and candy that will light up every taste bud on your tongue
at one time. I don't remember the name of it.

Suntory's Yamazaki 12 and 18 are fantastic. Kinda their own thing. One of my favorite whiskeys, but ever since the tsunami and the increasing whiskey culture of Japan, it's been hard to find. It used to be a $35 bottle. Now it's like $80+.

The Suntory Toki whiskey I'm not a fan of though, wonder if that's what Revray tried. Also thought it tasted weak. But give Yamazaki a try.

I'd also buy the various Pocky sticks (states tend to just get chocolate), and the weird Oreos.

On topic though, if you have an A/T, I think there's a factory remote start you can buy that's kinda baller with an LCD screen. I looked into it briefly though due to price, and have no idea if it works with USDM vehicles.

They also have interior footwell lighting not available here.

And Amuse makes a brace that replaces our stock aluminum in-cabin one. With harness anchors and all. If you're baller that'd be pretty unique.

Oh, and there's also all the Nismo S-Tune shiftknobs. They're not that pricey and easily travel.
