The fleeting moment of kendo
that words cannot capture, made visible.
That one point—conveyed faster than words.
"The hands float," "weak footwork"—hard-to-convey issues in a strike, pinned to a single moment in the video and shown intuitively with shapes and comments. Minimal effort for instructors, maximum understanding for students.

Give the “timing” of coaching a form of its own.
Pin the exact moment
Drop a pin at a specific moment in the video and attach shapes and comments there. It is always clear which instant you are coaching.
Six drawing tools
Freehand, line, arrow, angle-measurement line, stamp, and text. Draw the angle of the shinai or the posture right on the footage to get your point across.
1/30-second frame stepping
Step through the moment of a strike frame by frame with the ← → keys. Combined with slow playback (0.25–2.0×), you catch breakdowns you used to miss.
Straight from your phone
Post the vertical video you shot as-is. Works on iOS Safari / Android Chrome, so you can review on the go.
Share within a group
Connect with teammates via an invite code and share videos. Members of the same group can view and annotate each other's practice.
Record by category
Save videos by category such as men, kote, and kirikaeshi. Choose who can see each one: only you, your group, or specific members.
Get it across by
“drawing” right on the video.
フリーハンド・直線・角度測定線・スタンプ・テキスト・ぼかし。竹刀の角度や手元の位置を、映像コンテンツ矩形を基準にした相対座標で正確に記録。生徒側でも同じ位置に再現されます。
- ✓ Relative coordinates mean it never drifts, even on a different device
- ✓ 「ぼかし」で顔など見せたくない部分を隠せる（プライバシー保護）
- ✓ Supports undo, deleting shapes, and keeping work in progress (drafts)
- ✓ Comments can be edited later, and deleted per pin
More than video annotation.
Everything around kendo practice, in one place.
From records and analysis to running your group. We have gathered the features you use in daily practice into KendoInsight.
Video annotation
Visualize the moment of a strike with pins and six drawing tools. Manage status with "Coaching complete."
Score records & performance analytics
Record scores for individual and team matches. Win rate, favorite techniques, striking opportunities, and by-team / by-order breakdowns are tallied automatically.
Practice journal & condition analysis
Keep a journal of daily practice. See trends in your condition (a 5-level scale from great to poor) and by day of week or practice menu.
Task management
Register weaknesses and goals as tasks and manage them by status (not started, in progress, resolved). Work on them solo or share within a group.
Practice schedule & attendance
Personal plans and group practice on a single calendar. Check and respond to attendance, and send reminders.
Team lineups & match tables
Register players, assign them to the order from senpo to taisho, and auto-generate a round-robin match table. Results are also saved to your score records.
Practice menus
Compile menus such as suburi, kirikaeshi, and jigeiko; the instructor finalizes them and shares them with the group.
Groups & board
Connect with teammates via an invite code and share videos and records. Keep announcements together on the board.
PWA & push notifications
Add it to your home screen and use it like an app. Push notifications keep you from missing things.
From posting to review, in four steps.
Film and post your practice
Upload a video you filmed on your phone, and share it with a category and a self-review comment.
Pin and annotate
Open a video from the list or a group, and draw shapes and comments on the moments that catch your eye.
Mark coaching complete
"Coaching complete" switches the status to "Reviewed." Work in progress stays as a draft, so you can resume later.
Review with pins
Tap a pin to jump to the spot. Step frame by frame and repeat the points you need to fix.
For instructors
Optimized for landscape on PC and tablet. Join a group and you can review members' practice videos efficiently while filtering by status, category, and date. "Coaching complete" switches the status to "Reviewed."
For students
Post the practice video you shot on your phone as-is. Tap a pin from your teacher to jump straight to that moment. Step frame by frame with ← → and review the points to fix as many times as you like.
