About

Japanese video editor for YouTube, Shorts/Reels, tutorials, and product explainers. I turn supplied footage into clear, platform-ready videos with structured cuts, readable Japanese captions, clean audio, natural pacing, and final exports ready to publish.

VIEW FIRST: “Plant Care Tutorial — Kikko-ryu Production” below. This 14:44 self-operated/in-house project covers planning, filming, structure, editing, captions, audio, thumbnail, export, and publishing. It demonstrates specialist information made easy to follow and product details shown clearly.

I have completed paid client video projects. Public client footage is not displayed without permission, and self-operated work is clearly labeled.

Primary tool: Adobe Premiere Pro. Typical first draft after all footage and instructions are confirmed: 2–3 business days for a 30–60 second short, or 3–5 business days for a 5–15 minute YouTube video. Current weekly capacity: about 3–5 short videos, or 1–2 longer videos. Export format, revision scope, and editable project-file delivery are confirmed before work begins.

Based in Japan (JST). Written English instructions and feedback are welcome.
