We’ve told you before about the growing popularity of pets in Japan, and how these animals which were once banished to the outdoors, are now gaining entry into some of the world’s most fastidious homes. This has caused a revolution of sorts, as apartments and hotels are slowly adjusting to the needs of four-footed companions.

According to one report:

Demand for accommodation that accepts pets is rising. A survey conducted by the Pet Food Manufacturers Association in 2004 showed the number of households keeping pets indoors was double that of those keeping pets outdoors. Single-person households have a particularly high rate of indoor pets — about 65 percent of dogs and 79 percent of cats owned by single owners in the survey were kept indoors.

Privileges for pets are starting to extend beyond the home and include spas and special hotel packages.

Oedo Onsen Monogatari spa in Tokyo last year built an annex with a spa and bathing facility exclusively for dogs. Tsunayoshi no Yu, named after the fifth Tokugawa shogun, who issued edicts to protect dogs and other animals, gets up to 90 dogs with their owners in tow on a busy day.

Meanwhile, Asahi reports that:

At the Nihonbashi outlet of Japan’s largest department store company, Takashimaya Co., dog owners take their pets to the roof for a romp in the dog park. Usually they time their visits in the cooler hours of morning or evening.
