Kaimu

One Ok Rock's song 'Kaimu' delves into the existential and philosophical questions about the nature of reality and human existence. The lyrics ponder the hypothetical scenario of the world ending tomorrow, questioning the emotions and actions that would be left behind. The song challenges listeners to consider how many people would be willing to sacrifice their lives to save the planet, highlighting a sense of disillusionment with humanity's often superficial and self-centered nature.

The chorus, repeating the word 'kaimu' (which translates to 'nothingness' or 'void'), emphasizes the emptiness and futility the band perceives in the world. The lyrics criticize the tendency of people to speak grandly without taking meaningful action, suggesting that such behavior leads to no real change. This sentiment is further reinforced by the imagery of a child’s play, implying that the actions of humanity are trivial and inconsequential in the grand scheme of things.

The song also explores the idea that the world and everything in it might be an artificial construct, akin to a fish in a tank or a puppet in a play. This metaphor extends to natural disasters, which are depicted as mere pranks by an unseen creator. This perspective leads to a sense of helplessness and inevitability, as the lyrics suggest that even human growth and evolution might be just another form of entertainment for this creator. The song concludes with a reflection on the possibility that everything, including forests, buildings, and people, might be illusions created by someone else, leaving the listener to question their own reality and existence.
