Kumamoto is presented as a positive model in this article:

“Even then, Kumamoto, a prefecture in Japan, has been successful in reducing the number of killings substantially. Kumamoto, back in 2003, killed 1,200 dogs and cats, but succeeded in reducing this to mere 13 in 2013, due to a specific action taken. Kumamoto was one among many prefectures killing large number of animals back in 2001. And when Mr. Fuchibe, who just had been promoted to Chief Director of Kumamoto Animal Care Center asked each and every worker there about their thoughts towards killing animals, they all answered that they didn’t want to kill any more animals. So, Fuchibe began action, first holding a conference with the Veterinary Medical Association, the Humane Society, and various personnel from the pet field. Things didn’t go easy first, but they all had the same goal — to abolish the killing. Eventually, they were able to reduce the number of animals destroyed to 13 in 2013.”
