カタカナにしたか理解出来なかったか
日本語ってのはむずかしいねえ

The Japanese word "kaizen" means simply "improvement," with no
inherent meaning of either "continuous" or "Japanese philosophy"; the
word refers to any improvement, one-time or continuous, large or small, in
the same sense as the mundane English word "improvement".[3] However,
given the common practice in Japan of labeling industrial or business
improvement techniques with the word "kaizen" (for lack of a specific
Japanese word meaning "continuous improvement" or "philosophy of
improvement"), especially in the case of oft-emulated practices
spearheaded by Toyota, the word kaizen in English is typically applied to
measures for implementing continuous improvement, or even taken to
mean a "Japanese philosophy" thereof. The discussion below focuses on
such interpretations of the word, as frequently used in the context of
modern management discussions
