Prime Minister Shinzo Abe said Saturday he has decided on a July 7-9 schedule for the Group of Eight summit to be hosted by Japan next year in the Lake Toya resort area in Hokkaido.

Abe, visiting the town of Toyako after choosing it last month as the site for the summit, said Japan will officially call the gathering the "Hokkaido-Toyako Summit" in Japanese. The official English name has not been decided.

"I was convinced that it is the right place to speak about the environment, which is one of the themes next year," Abe said after visiting various locations with Hokkaido Gov. Harumi Takahashi.

These included the Windsor Hotel Toya Resort & Spa, the planned venue of the G8 summit, which stands atop a 600-meter mountain overlooking Lake Toya.

"I would like to show a beautiful Japan, Japan's beautiful nature from this place," Abe said.

He vowed to take the initiative on environmental and global warming issues when his G8 counterparts from Britain, Canada, France, Germany, Italy, Russia and the United States gather in Heiligendamm, Germany, next month for this year's summit.

On the three-day schedule for the '08 summit, Abe said it was decided after arrangements with other leaders.

"The weather in Toyako is also good at that time of the year, so I decided on that date," Abe said.
