Unique vending machines selling frozen food ranging from slices of fish to Swiss rolls have been gaining popularity in northern Japan, providing a new source of income for pandemic-hit businesses while allowing customers to purchase goods without the risk of contracting COVID-19.

One vending machine, installed by fish wholesaler Chibasuisan in a residential area of Sapporo, supplies boneless slices of fish such as salmon and mackerel priced from ¥300 ($2.70) to ¥1,500.

"It's nice to be able to take your time to decide what to get without having in-person interactions," said Teruyuki Nagai, 49, who bought 500 grams of salmon from the machine in late September.
