Deputy Editor of RAG MUSIC. JFC-certified fact-checker. I’m Sasashina, a mom currently raising an elementary schooler and a preschooler. During my student years at Kyoto College of Science and Technology, I studied a wide range of fields including sound, lighting, and video technology, building a foundation in comprehensive stage production and creative expression. After graduation, I joined a music production company, where I still work, consistently building experience in production and engaging in a variety of music-centered tasks. Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

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!”
