Three major Japanese convenience store operators posted growth in their group operating revenues and profits in the March-May first quarter of the current business year, according to their earnings reports. Retail giant Seven & I Holdings, the operator of industry leader Seven-Eleven Japan, saw its mainstay overseas convenience store operations recover thanks to labor and other cost cuts. FamilyMart's operating profit grew 17.9% from a year before to 27.8 billion, as advertisements featuring Los Angeles Dodgers star Shohei Ohtani helped attract more customers and boost sales of onigiri rice balls. FamilyMart also attracted budget-minded consumers thanks to its discount sales of food items such as eggs and milk. As a result, the company's net profit jumped 36.7% to a record 21.1 billion.
