Is Meiji Chinese or Japanese?

Could you please clarify for me, is Meiji referring to a specific era, a cultural movement, or a geographical location? And in regards to its origin, are we discussing the context of China or Japan? It's an intriguing question, as Meiji holds significant historical significance, so I'm curious to learn more about its origins and cultural associations. Is Meiji indeed associated with Japan, particularly the period of modernization and westernization that occurred during the late 19th and early 20th centuries? Or is there a lesser-known connection to China that I'm not aware of?
