Soak corn in warm water for 10 minutes. Peel back the corn husks, leaving them attached, and remove the silk from the corn. Separate the husks into thirds and braid.
Combine the butter, hoisin sauce, honey, soy sauce, and lime juice. Brush the corn with the butter and grill, turning often and basting with more butter until the corn is cooked and starting to get grill marks, about 10 minutes.
Transfer the corn to a serving platter and sprinkle with the furikake and cilantro.
