Prices are slated to rise in Japan in September for 1,422 food products and beverages made by 195 major makers, research firm Teikoku Databank said Friday.

"The reasons for price hikes have shifted from the weaker yen to domestic factors," a research firm official said, as the number of companies citing higher logistics and labor costs has grown significantly.

The monthly total of food products and beverages with higher prices will rise 0.6% from a year earlier, up for the ninth consecutive month.

In September, prices will rise for 427 seasoning products, such as sauce and mayonnaise. Prices will also go up for many frozen food products and confectionery items such as chocolate.

Kewpie will raise the prices of 66 items, including household-use mayonnaise and dressing products. Morinaga Milk Industry will raise the prices of its popular Pino bite-sized chocolate-coated ice creams and 17 other items.

According to Teikoku Databank, the total number of items for which prices have been raised this year stands at 20,034, topping 20,000 for the first time in two years.

The annual total may reach the 2022 level of 25,768 items, when price increases for food and beverage products began in full swing in the country, according to the research firm.
