TOKYO, July 1 (Reuters) - New automobile sales in Japan, excluding 660cc minivehicles, fell 13.5 percent in June from a year earlier to 243,342 vehicles, the lowest level for that month in 35 years, the Japan Automobile Dealers Association said on Wednesday.

The pace of decline eased from the previous months thanks to the introduction of tax and cash incentives on cleaner cars, but still marked the ninth straight month of double-digit percentage falls, an official at the industry group said. [ID:nT129922]

"Until a convincing economic recovery is seen, there's no room for optimism," he told reporters.

June marked the 11th successive month of year-on-year decline, even though there was one extra day for registration compared with the year-earlier month. [ID:nT113927]

Sales at top-ranked Toyota Motor Corp (7203.T), excluding the Lexus brand, fell 11.4 percent, also for the 11th straight month, despite a full-month contribution from the new Prius hybrid.

Honda Motor Co's (7267.T) sales gained 5.7 percent for the third consecutive rise, thanks to the Insight hybrid. Honda was the only brand to increase its sales in June.

Nissan Motor Co's (7201.T) sales fell 20.8 percent.

For the January to June period, sales of non-mini vehicles totalled 1,303,766 units, down 26.4 percent from a year earlier.

Sales of 660cc minivehicles, which get preferential tax treatment, fell 16.2 percent in June to 138,943 units, the Japan Mini Vehicle Association said. [ID:nT78592]
