It's common practice to go grocery shopping nearly every day in Japan. But because of the COVID-19 pandemic, it's a good idea to minimize the number of food shopping trips you take. How? By helping your produce keep longer in the fridge and freezer.
Fresh vegetables
Whole vegetables keep longer, so buy a whole cabbage, head of lettuce or kabocha squash, rather than a cut piece, if your refrigerator can accommodate them. Instead of loose bagged salad leaves, get spinach with the roots on. Root vegetables like daikon radish, turnips and carrots will keep a lot longer than leafy vegetables, especially if you store them vertically.
