Akifumi Gunji郡司淳史
Vibes Manager
Born in Tokyo, June 15, 1988.
Founder & CEO, Sinden Inc.
After graduating from Nihon University, I joined a media company. When I couldn't find a job after leaving, I made a living through construction, cleaning, and moving work — and taught myself planning along the way, eventually going freelance. Since then, I've advised companies including Gaiax Co., Ltd. and the JR West Group.
Music events, outdoor festivals, travel — these hobbies eventually led me to tea. In 2016, I launched the tea project "VAISA" with friends. Later, together with Hiroyuki Karikomi (creative director) and Yusuke Daimon (architect and spatial designer), I co-founded Sinden Inc., built around the idea of "putting heart back into things."
Along the way I've started small businesses — the music event "choutsugai," the outdoor festival "caravan," and Gunji School, a community school built around the motto "just move first."
I work and live by a simple line: be kind to others and to yourself — with love, gratitude, and respect.
In 2018, I started "Homeru (Praise) Bar" with Sanpo Yamanaka (editor) and Suzuka Nakanishi (writer) — a space built around the act of praising others. We've now praised over 2,000 people, and the format has grown into work with companies on team-building. I also lecture at Nihon University and other schools.
Currently using biological data to optimize my own body.
As a precision nutrition counselor, I also read other people's data.
Traveling all 47 prefectures of Japan for an art project.
In 2027, moving to Barcelona.
