Sales at department stores in Japan dropped 7.6 percent to 588 billion yen, or $5.54 billion, in June, the Japan Department Stores Association said. Clothing sales, the largest revenue component of the nation’s 280 stores, decreased 14 percent to 199.7 billion yen, or $1.88 billion. Sales of women’s apparel dropped 14.3 percent. The slide was partly due to slower personal consumption on rising oil and food prices and an unfavorable macroeconomic climate, the association said. Department store sales in the Tokyo area fell 7.4 percent to 152.5 billion yen, or $1.43 billion compared with a year ago, the fourth consecutive month of decline. The drop in June was partly attributed to unfavorable weather, although umbrellas and rain shoes sold well. Dollar figures were converted at the exchange rate as of June 30.
