On a set outside Tokyo, Momoko Nishiyama sits with the drama's director and watches as a man undresses a woman, guiding the love scene as one of just two "intimacy coordinators" in Japan.
The country's film and television industry has been hit by a string of recent sexual abuse allegations that have led to apologies and movies being pulled.
But while Hollywood has embraced intimacy coordinators in the wake of the #MeToo movement, they are still relatively new in Japan, where public reaction to the latest scandals has been muted.
"In the United States, everyone knows what an intimacy coordinator is, but in Japan, I have to start by explaining what it is that I do, and that I'm not the director's enemy," Nishiyama told AFP.
The 43-year-old's recent projects include a TV series with multiple intimate scenes.
On set, she confers with the director and observes actors, advising them how to move and adjusting their outfits.
But her work starts well before anyone shouts "action", beginning with a close read of the script.
She then meets privately with each actor to determine their boundaries.
"This is a scene without a bra. If we don't show your chest, are you okay with it?" is one question she might ask.
For 23-year-old actor Asuka Kawazu, Nishiyama offers reassurance.
"Her presence made discussions easier," she told AFP.
Without an intimacy coordinator, "a case could arise where we agree on something, but then when shooting we realise we're going much further than we had planned," she said.
- 'Lack of solidarity' -
Despite several high-profile allegations, the #MeToo movement was less pervasive in Japan than in some other developed countries.
But Nishiyama has seen demand for her services increase after multiple accusations of sexual harassment and abuse in her industry.
Some of the allegations prompted a group of directors including celebrated auteur Hirokazu Kore-eda to call for change, but the reaction from other professionals in the field was more subdued.
"Unlike in the West or South Korea where the #MeToo movement took hold, the Japanese industry wasn't able to change."
"I think it shows a lack of solidarity between workers in the industry, where there is no organisation to unite and protect them," she said.
The group hoped its statement "would make it easier for people to speak out", said Nishikawa.
The directors back the use of intimacy coordinators, though Nishikawa cautions that won't be enough to end abuse off-set.
Still, their presence shows that "the safety and dignity of actors and staff" are more protected.
"That can create an atmosphere that discourages harassment."
She and her fellow directors also want sensitivity training and industry guidelines for casting and shooting, warning that otherwise "incidents and accidents" will keep happening.
- Modesty garments -
On set in Tokyo, director Kenji Kuwashima is happy having Nishiyama there, and sees her as "defending both parties".
"In the end, everyone wants the same thing: to make the best production possible," he told AFP.
"Until now, relations were much more top-down, with the director saying 'do this', but it's become more equal and both sides benefit."
When preparing to go on set, Nishiyama gathers props that help keep scenes realistic while protecting actors.
She's never without a range of silicone patches that prevent contact between intimate parts of the body, as well as "maebari" -- a made-to-measure modesty garment.
"I've always got about 30 with me," she said, laughing.
Nishiyama started her career as a production coordinator, mainly for Japanese shoots abroad, and took up her current role after an intensive online US training course.
The rising demand for her services suggests "things are changing, little by little", she said.
But she admits feeling "a little powerless" to hear that some industry players accused of abuse have continued to work unchallenged.
"There are people who want to change things, and there are more and more film sets with a healthy atmosphere. But I think that things must change more."
