Japan’s first ‘naked restaurant’ is due to open in Tokyo on July 29 under the name Amrita, which stems from the Sanskrit word for immortality.

But, full nudity is off the menu, since guests will be called to wear paper underwear and the restaurant’s management has set very strict entry rules.

The age limit is 18 to 60 and anyone more than 15kg over the average weight for their height will be asked not to make a reservation, the Independent reports.

However, those who do turn up and appear overweight could face the embarrassing ordeal of being weighed and rejected with no ticket refund. Those who have tattoos will also be turned away.

Rules on the restaurant’s website state: ” We ask anyone more than 15 kg [33 lbs] above the average weight for their height to refrain from making a reservation.”

“In London they allow overweight patrons in and some guests complained they had a terrible experience,” Amrita spokeswoman Miki Komatsu told AFP.

She added: “If fat people are allowed in it could be miserable for some guests. Guests can see the guidelines clearly on our homepage. We are aiming for a sort of Roman aesthetic, like the beautiful paintings you see in museums.”

Those who meet all the criteria set by the restaurant must follow other rules, too.

Diners may not ‘cause a nuisance to other diners’ with uninvited small talk or tough other restaurant goers, while their cameras and mobiles phones have to be locked in a box on the table.

And even though it is called a “naked” restaurant, customers will be asked to wear paper underwear, while Western waiters will be wearing g-strings as they perform a stage show for the diners.
