The 39-year-old will complete the third marathon of her career on Sunday having run her first in London last year before following that up with an outing in New York.
Pavey clocked 2:28:24hours in London and 2:28:42 in America however, unlike on those two occasions, she has travelled to Japan with a clean bill of health.
She has also been buoyed by her two seventh-place finishes over 5,000m and 10,000m at the London 2012 Olympics and win at the Great South Run at the end of October.
Pavey has spent almost two weeks in Japan, learning from the lessons she was dealt at the World Championships in Osaka in 2007 where she was fourth in the 10,000m and ninth in the 5,000m.
And, admitting to being injury free, Pavey, who made her fourth Olympic appearance at London 2012 in the summer, is confident the Yokohama Marathon can be one to remember.
"When I have raced in America I have always felt OK in the week when I have flown out there but going to Japan is going to be much more difficult," said Pavey.
"I am using the experience I had when I went with the British team to the holding camp in Macau before the World Championships in Osaka.
"Then I found it took much longer to get used to the time difference. That is why I wanted to fly out earlier to give myself the best chance to get used to the time changes.
"And I hope I am in better shape for Japan than ever before. I have only done two marathons, but both of those came off the back of stress fractures which obviously had an impact.
"This time should be a lot better as I am coming off a very good track season culminating with the Olympics.
"I have been able to train hard and consistently with few disruptions and I feel I am better shape now than before my previous two marathons."
