I might agree with your wife. :P

Nishiki uses an offshoot of Calrose rice, which is okay but popular Japanese rice is often Koshihikari or Yumipurika: https://en.wikipedia.org/wiki/Nishiki_rice (do click the link for SICK web art on a random wikipedia page)

If you can find some https://umamimart.com/products/tamaki-haiga-rice is one of my favs.

Or as someone commented below the rice from The Rice Factory is solid if you are looking for a treat: https://trf-ny.com/collections/rice

I currently have 3 varieties from TRF in my cupboard :D
