I’ve been playing the Electone since I was six, mainly performing Disney music, anime songs, and music from dramas and films. I post performance videos on YouTube and social media, and I also give concerts. Building on my Electone experience, I took up synthesizer and piano during my student years and performed at school-sponsored events. As a writer, I’ve covered not only music-related topics but a wide range of genres, so I hope to draw on my experience to deliver articles that make readers think, “I want to try that!” or “I want to listen to that!”

Because my ear was gnawed by a mouse, and I cried for three days and nights until the paint peeled off.

The secret behind Doraemon’s blue color is related to what happened after his ears— which he was supposed to have—were gnawed off by a mouse. Shocked by the incident, Doraemon cried for three days and three nights, causing his paint to peel off, and that’s how he turned into the blue color that became his trademark. This backstory reflects a change alongside his emotions and is one of the key episodes for understanding his character more deeply.
