Kokoro

The song 'Kokoro' by VOCALOID tells the poignant story of a robot created by a lonely scientist. This robot, described as a 'miracle' due to its advanced capabilities, lacks one crucial element: a heart, or 'kokoro' in Japanese. The lyrics delve into the robot's journey over 200 years, during which it remains alone, yearning to understand the concept of a heart that its creator could not program. This longing symbolizes the robot's desire to experience human emotions and connections, highlighting the intrinsic value of having a heart.

As the song progresses, the robot begins to experience emotions for the first time. It feels tears, trembling, and an accelerating heartbeat, all of which signify the awakening of its 'kokoro.' These sensations are new and mysterious to the robot, representing the complex and often contradictory nature of human emotions. The robot learns about joy, sadness, and the depth of these feelings, which it finds both wondrous and painful. This awakening is a metaphor for the human experience of discovering and grappling with emotions.

In the final verses, the robot expresses gratitude to its creator for giving it life and the ability to feel. The repeated 'thank you' signifies the robot's deep appreciation for the gift of a heart, despite the accompanying pain and sorrow. This gratitude underscores the song's message about the importance of emotions in making life meaningful. The robot's journey from a mere machine to an emotional being reflects the universal human quest for connection, understanding, and purpose.
