Generally, Japanese knives are lighter, feel more balanced in the hand and feature steel that is harder, thinner and able to hold an edge for a longer time.

Since they're thinner, they're a little more prone to the tip breaking or the blade chipping, so Japanese knives tend to need more maintenance.Why are Japanese knives better?

Why is Japanese steel so good?
Japanese-Style SteelKnives made by Japanese manufacturers traditionally use high-carbon steel. It's a superior material for knife blades because it holds its super-sharp edge longer than stainless steel, due to a rating of 60-61 on the Rockwell scale. High-carbon steel is significantly harder but also more brittle.
