Tokyo: Consumers across Japan are facing higher food costs as the average retail price of pork loin reached a record level in September, while egg prices remained near their previous peak.

The latest nationwide food-price survey showed that pork loin was selling for an average of 293 yen per 100 grams during the latest reporting period. That was the highest level recorded since Japan began conducting the survey in 2003.

Egg prices also remained unusually high. A package containing 10 mixed-size eggs averaged 309 yen, matching the record price previously recorded several times this year.

Several factors are contributing to the increase. For pork, the weaker yen has raised the cost of imported products and related inputs, while stronger international demand has also encouraged greater demand for domestically produced pork.

Egg supplies continue to feel the effects of the avian influenza outbreaks recorded last year. At the same time, seasonal demand has increased as restaurants and fast-food chains launch autumn campaigns featuring egg-based products.

The price increases are adding another challenge for Japanese households already dealing with elevated living costs. Food prices have become an important part of Japan’s inflation debate as consumers adjust their shopping habits.

The latest figures were based on price checks conducted at hundreds of retail stores across Japan between September 7 and 9, providing a nationwide snapshot of consumer food prices.

The situation also illustrates how exchange-rate movements, global commodity markets, animal-disease outbreaks and seasonal consumer demand can combine to influence prices in Japanese supermarkets.

With pork and eggs both remaining expensive, households and food businesses may continue to look for alternatives if prices remain elevated in the coming months.
