Earlier Japan had inflicted a first defeat on Chinese Taipei, who bounced back to beat New Zealand 6-5, while China fell in their first game of the day 11-5 to Korea to sit with one win and three losses.
Australia lost both of their matches, 9-4 to New Zealand and 9-6 to Korea, who have a two and two record after two days with Chinese Taipei second and Morozumi's Japan leading the way.
"We played really well in both games," said Morozumi. "I think we have started so well because we had really good practice in Canada then we went back to Japan a little earlier than China returned home.
"I think has helped us with our general condition and performance levels so far. We are focused on every single shot, one game at a time, and I think that will be the key to maintaining our good form this week."
In the women's draw Korea remain unbeaten from their three games so far after a 9-2 defeat of China while New Zealand claimed their first win with an 8-6 defeat of Australia.
