I design presentations that make ideas
clear, structured, and actionable.
I’m Junko Mack, a presentation designer based in the United States.
I design presentations that help businesses communicate clearly — structuring complex ideas into messages that global audiences can understand and act on.
I also work in Japanese and English, supporting Japanese companies expanding into global markets.
Many business presentations struggle to communicate their real value. Slides become overloaded with information, messages lose focus, and the story becomes difficult to follow. That’s where I come in.
Through Information × Structure × Design, I create presentations that guide understanding and action.
Background
After graduating from a university in the United States, I returned to Japan and spent nearly a decade working in marketing and digital roles at Hewlett-Packard Japan, Dell Software Japan, and Stratasys Japan.
This experience shaped how I approach communication — not just visually, but strategically.
In 2016, I relocated to the United States, where I continued developing my skills in web design and digital marketing while raising my family.
Today, with over 10 years of marketing experience at global tech companies in Japan, I design presentations that help Japanese businesses communicate their value clearly in global markets.
I don’t just design slides — I design how ideas are understood across cultures and audiences.
This approach also extends to landing pages and web experiences—designing not just how things look, but how people move, understand, and take action.
