JINS, the Japanese low-cost optical retailer, has reported a slight increase in H1 revenues to 31,634 million Japanese yen (€237.6m-$290.6m), or 0.4 percent higher than in H1 2020. Year-on-year, increases in eyewear sales of 4.0 percent and 6.2 percent, respectively, in Japan and abroad during the first half of the year cushioned the impact of the discontinuation of the company’s accessories’ business. However, comparable store sales in Japan, which represent roughly 80 percent of total revenues, declined by 3.8 percent in Q1 and 2.9 percent in Q2 as compared to the same quarters in the past year. The company added 22 stores to its network during the semester reaching a total of 649 retail locations including 428 in Japan, 168 in China, 33 in Taiwan, 6 in Hong Kong and 5 in the U.S. Gross profit margin gained 1.7 percentage point to 79.2 percent thanks to the dropout of the accessories’ segment, while operating margin lost two percentage points to 8.4 percent because of higher marketing and R&D expenses. JINS said it increased its investment in eyeglass-type medical devices aimed at slowing down myopia progression. The company expects a 16.4 percent increase in its topline to ¥70,100 million (€526.5m-$643.9m) and an operating margin of 11.7 percent for the current fiscal year.
