Human Movement
× Robotics
Those who know human movement
create how robots move.
Those who know human movement

Observe in the field, form a hypothesis, validate it as technology.
AlphaEdge is a Tokyo-based company conducting research and development in humanoid robot motion control.
We run our own hands-on field site — the personal training gym FitSync —
observing daily how the human body actually moves,
while building AI systems we implement ourselves rather than merely use.
At the core of AlphaEdge is R&D in humanoid robot motion control.
How does a person hold a posture, respond to a disturbance,
and move into the next action?
We pursue this question in physics simulation.
With a view to how insights into human movement
might one day inform the motion control of humanoid robots,
we conduct research and development in physics simulation.
Having reproduced and validated published standard control methods, we are now in the experimental stage of our own control research.
Specific control methods, evaluation metrics, and performance data
are not published while R&D is in progress.
The questions robot motion control faces —
posture, balance, and response to disturbance —
are the same questions we see every day
on the floor of a training gym.
Observations born at FitSync become
measurable questions, and AlphaEdge
validates them as technology.
That consistent structure is the foundation of our R&D.
Anyone can use generative AI today.
What AlphaEdge builds is implementation:
AI systems we design, build, and keep running every day.
A fully automated video production pipeline,
an app of our own with AI translation and voice synthesis built in,
and acquisition infrastructure for the AI search era —
all implemented in-house and running in production.
The other core of AlphaEdge is our in-house personal training brand, FitSync.
Instruction is designed by our founder — a former professional fighter
with around 70 bouts across karate, kickboxing and Muay Thai —
around the distinctive theme of the "Relaxed Tanden" and how advanced movers use the body.
Eight Tokyo gyms (Roppongi, Shinjuku-Gyoemmae, Nishi-Shinjuku, Shinjuku South (Yoyogi), Shibuya, Ginza, Azabu-Juban, Pilates & Body Azabu-Juban) plus on-site lessons.

We continue to provide specialized services in English × fitness
for high-net-worth and inbound guests.
CEO Issei Shima serves simultaneously as trainer, developer, and marketer.
Rather than simply "using AI," he implements AI in day-to-day operations
and drives the business firsthand.
Building something is half the work; carrying it to where it is found is the other half.
AlphaEdge designs its sites, content and publishing in Japanese, English and Chinese,
implementing acquisition infrastructure across search, AI search and social platforms.
We design and operate our brand sites and content
in three languages — Japanese, English and Chinese —
delivering fitness information across language barriers.
We use Xiaohongshu (RED), one of China's largest lifestyle social platforms,
to reach Chinese-speaking fitness audiences.
Community building and inbound acquisition run in parallel.
Designed so AI search experiences such as ChatGPT, Claude, Perplexity,
and Google's AI Overviews can cite our information accurately.
Not relying on gimmicks, but building on SEO fundamentals
and genuinely helpful content,
we implement acquisition infrastructure for the AI era.
Everything above actually runs, every day.
We operate these as our own media while continuing to develop and improve them.
We publish on two YouTube channels: Fitness English daily, and the Tanden Channel every Friday.
"Fitness English" — released in both Japanese and English.
"Tanden Channel" — sharing the ‘Relaxed Tanden’ taught at our brand FitSync,
with weekly short videos (every Friday) on the tanden and how to use your body
(Japanese audio with English subtitles).
For both channels, production is automated by our AI pipeline —
from script to voice synthesis, subtitles, and publishing.
Type Japanese and instantly get the English phrase,
katakana reading and audio — a personal English phrasebook app
published under our brand FitSync.
Free, no registration; data stays on your device.
Built in-house with AI translation and voice synthesis.
