Neko Colle (short for "Cat Collection") is a relaxed, laid-back cafe located near central Yamagata's tourist attractions. It's currently Yamagata's only cat cafe, and many of the twenty residents here are rescue cats from local shelters. All in all they seem to be a bit livelier and more playful than average cafe cats, and the friendly staff make efforts to keep them entertained.
The spacious playroom is furnished with several comfortable sofas, although you may need to clear a space for yourself. There's also a good supply of cat toys, and the usual coffee and tea available for visitors.
