Kenji did a great video walking around Uwajimaya explaining the different varieties of common Japanese ingredients and what he recommends getting. I’d say anyone looking to dip their toes or season experts of Japanese cooking will find some good info here.

I don’t know why, but mushrooms in particular have been obscenely expensive at Uwajimaya for the last couple years. Go anywhere else for them.
