Are rickshaws Japanese or Chinese?

I'm curious to know, are rickshaws more closely associated with Japanese culture or Chinese culture? It's a question that's often debated among travelers and enthusiasts of East Asian traditions. On one hand, rickshaws seem to be a ubiquitous sight in many parts of Asia, including both Japan and China. But is there a definitive answer to where they originated and which country they're more closely tied to? I'd love to hear your thoughts on this fascinating topic.
