The text is from a pet service in Kabukicho, a famous sex service district of Tokyo. The text reads: 
Pet Hotel ¥2500 
Shampoo ¥3000 
Trimming ¥4500 
Cute 
Many puppies and kittens come here 
"Japanese only" is a usual text at the doors of Japanese sex services, meaning that the access is restricted only for Japanese (men).
