Hello! I’m Seiko Yamaguchi.
I work as a strategist, consultant, and project manager, providing comprehensive support for B2B companies—from digital marketing strategy to project management.
About Me
Since becoming independent in 2015, I have leveraged the expertise I gained at an IT consulting firm to offer end-to-end support—from overall marketing strategy design and the implementation of advanced tools such as HubSpot and AI, to streamlining operations and executing lead-generation initiatives.
As a project manager, I also focus on PMBOK-based elements such as project scope, resource management, scheduling, and risk management. My strength lies in smoothly facilitating communication among both internal and external stakeholders, ultimately delivering results quickly and effectively.
My Strengths
My key strength is the fusion of data-driven analysis and strong communication. By drawing on my qualification in psychological counseling to build consensus among stakeholders, I optimally leverage digital tools such as MA/SFA and lead entire projects to achieve tangible results even in short time frames.
I also have extensive experience in creative areas like website analytics, advertising operations, SEO, and content production, as well as in DX-driven fields such as marketing automation (MA), SFA, and business card management software.
FACING ANY ISSUES?
If you’re looking to fundamentally revamp your existing marketing initiatives or improve operational efficiency through digital solutions, please feel free to reach out. I will help turn your company’s vision into concrete actions and measurable results through a strategic perspective and proven project management.

What I love
I lead a digital nomad lifestyle based in Tokyo, spending time overseas. My goal is to apply the latest digital knowledge gained from living abroad to my work and to provide high-quality services through active self-care. My hobbies include stock investing, experiencing new technologies, studying, reading, diving, and practicing yoga.
