You can buy Edamame at walmart in stem bags for 1.50$ , go to any japanese store and buy okinawan sea salt and enjoy , its the same shit. All Edamame in japan is imported from the USA anyways lol My freezer always has bags of this. If you go to any japanese store and try and buy edamame in the same bag with japanese name its like 8 bucks for the same shit.
Most that stuff you listed is not really sushi, Us japanese do not even use or know were to buy cream cheese lol
When you get a chance really go to Aki hana and try the sushi A or B it has samples of traditional type sushi peices and is not that much. Once you taste sushi rice done right you will never go any other place.
