Yokohama want to try again to lure Nakamura away from La Liga before the start of the J-League season on March 6.
"It's a delicate process," Yokohama President Akira Kaetsu told the Sankei Sports newspaper. "We don't have much time."
F-Marinos manager Kazushi Kimura warned Nakamura could struggle to make an impact for Japan at this year's World Cup if he did not get regular first-team football.
"The situation needs to be sorted out quickly - for the player's sake," Kimura told the Nikkan Sports. "While he is not playing, he's losing his match sharpness.
"That's a worry before the World Cup. We would love to have him at Yokohama. We would score more goals with him on free-kick duty."
