A new law goes into effect in Japan on July 1, 2020, making it manditory for all grocery stores, convenience stores, and other retailers to charge a fee for single use plastic bags. The law doesn't specify the price, but does say it must be at least one yen. Many grocery stores already charge for bags. Where I shop, a small bag is three yen and a slightly bigger bag is five yen. Since I always have my daypack with me, it is more convenient for me to refuse the bag and carry things in my backpack.
Japan uses between 30 to 50 billion plastic bags a year (more than 300 bags per person each year), so reducing non-recyclable plastic is a priority for the country.
What about in your country? Is plastic waste a problem? Do stores charge for plastic shopping bags? Do you carry your own shopping bag? I'm curious to know.
