MIKIYA H.
Native Japanese SEO & Localization Specialist | Supported 70+ Clients
Japanese SEO, localization and marketing content for startups and global brands. I’m currently running SEO for a Dubai matcha e-commerce startup, writing Japanese SEO articles for a global travel eSIM brand, and creating YouTube scripts for an online education startup. Over 8 years in business and engineering roles, I've listened to clients' problems, proposed solutions and worked alongside them until things ran smoothly. That included launching production management systems for small manufacturers in Japan, covering orders, work instructions, purchasing, cost control and sales management, from setup to support after go-live. After that, I moved to Australia and worked in an international environment, adapting to cultural differences and a workplace very different from Japan's. Back in Japan, I worked as a freelance engineer and a company employee before going independent. I understand the challenges overseas teams often face in Japan: no one on the team can check Japanese, AI translations read unnatural, and content doesn't match what Japanese users actually search for. My goal is to make your Japanese content feel native and actually work in the Japanese market.
