# MAWASHI Vertical Brief

Date: 2026-07-16

## Core Idea

MAWASHI is a sumo AI matching vertical for athletes, coaches, stables, clubs, events, sponsors, and robot physical intelligence.

The first business surface is useful matching, not a crypto market:

- wrestler to coach,
- wrestler to practice partner,
- youth or amateur athlete to safe training path,
- coach to clinic or event,
- stable or club to community,
- approved wrestler knowledge to AI training and browser fight demos,
- sumo motion to robot physical-intelligence research.

## Why Sumo

Sumo is a strong physical-intelligence domain because it compresses many useful motion problems:

- stance,
- balance,
- foot pressure,
- explosive tachiai,
- grip selection,
- body angle,
- ring awareness,
- push / pull timing,
- recovery at the tawara,
- strength with cultural discipline and ritual.

Those problems are useful for both human sports products and robot physical intelligence.

## Team Advantage

User-provided context:

- The team includes a popular sumo wrestler.

Public page rule:

- Do not publish names, titles, rankings, tournament results, stable names, photos, likenesses, or endorsements until each person and organization approves the exact wording.
- For now, use generic phrasing such as "wrestler-led team context" or "approved rikishi knowledge layer."

## Zweispace Vertical Context

User-provided context says Zweispace is talking publicly in a PR Times context about specialized AI professional verticals such as AI税理士 and AI中小企業診断士.

MAWASHI should be framed as the sports, culture, and robot physical-intelligence member of the same vertical family:

- professional AI verticals for regulated or expert knowledge domains,
- BOX for boxing and sports physical intelligence,
- MAWASHI for sumo matching, balance, grip, and dohyo intelligence,
- JavaScript as the first public simulation and demo surface,
- real athletes and coaches as the human source of technique and trust.

Do not claim a direct PR Times quote, date, or URL until the exact release is verified.

## Safety Notes

MAWASHI should not give medical advice. It should not replace qualified coaches, medical professionals, stable rules, school rules, event operators, or official sumo governance.

For youth athletes, injury history, return-to-play decisions, intense collision training, weight change, and competition readiness, require explicit human coach and professional review.
