Whether you're looking for a birthday cake for your beagle, or oxygen therapy for your tabby, you can find countless ways to pamper your pet in Tokyo.

Japan has become a nation of animal lovers. According to the Pet Food Manufacturers' Association of Japan, the number of domestic cats and dogs in the country now stands at 26.8 million, up from 17.8 million 10 years ago. Many cafes and shops are now animal-friendly and there are several fun places for owners to take their furry friends out for a day on the town.

The menu at Les Deux Bleue in Toyosu's LaLaport shopping complex in Koto Ward reads like one from an upscale bistro — chicken-liver pate with a bountiful mix of organic vegetables, grilled beef and okara (soy pulp) hamburgers, apple pie with fresh cream and mint — except that's just for the dogs. "You can try it, but you'll definitely think it has no flavor," laughs manager Tastuaki Matsumura, who explains that the dog-menu ingredients are the same as those used in the dishes for people, but with one notable difference: The dog versions are completely additive-free. "We don't use any preservatives, salt or sugar," says Matsumura. "Everything is fresh and healthy."
