02Overview
What Auto Sportsland Sunagawa is like to drive.
The full circuit layout at Auto Sportsland Sunagawa is 1.44 miles with 22 corners worth setting up for. A generic track-day car in our model brakes hard 18 times a lap and is at full throttle for about 23% of the distance; the longest straight runs roughly 787 ft.
19 of the corners are slow (under 50 mph in the model), 0 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Auto Sportsland Sunagawa later.

The speed trace is a model, not a real lap: a generic track-day car (about 1.1 g of cornering grip, 1 g braking, 150 W/kg) driven on the computed line through an assumed 12 m wide track. Use it to see where the braking zones and flat-out sections are, not to predict your speeds. Elevation data for this track isn’t loaded yet.
04Corner by corner
The corners at Auto Sportsland Sunagawa.
TRACK’s own corner numbering (C1, C2…), found from the curvature of the mapped centerline. It isn’t the official turn numbering. Each diagram shows the computed line: the minimum-curvature path through an assumed 12 m wide track. It’s a geometric starting point. Your instructor’s line comes first.

Slow right-hander
↱ RightslowhairpinTRACK numbering
A slow right-hand hairpin that turns about 174°, tightening to a radius of roughly 5 m (16 ft). The model car brakes for about 140 m (459 ft), from 111 to 28 mph. The computed line turns in from the left side, takes an early apex, about 5 m before the geometric apex, and lets the car run out to the left on exit.

Every mapped loop at Auto Sportsland Sunagawa.
TRACK finds each closed loop in the OpenStreetMap raceway network. Named layouts come from OSM circuit relations; the rest are named by length, and some may be combinations the venue never runs. Your first session confirms which one you drove.

06Time it with TRACK
Drive Auto Sportsland Sunagawa. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Auto Sportsland Sunagawa and the layout from your GPS trace, then times every lap and sector with a live delta to your best.
- 1DetectTRACK matches your first few hundred metres against every mapped layout at Auto Sportsland Sunagawa, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is estimated. When you’re stopped, TRACK shows it on the map: accept it or tap to move it. You’re never asked while driving.
- 3Laps, timed retroactivelyLaps you drove before confirming are timed from the recorded trace, so you don’t lose your first session.
- 4Go furtherSync a GoPro for video with telemetry and let TRACK Engineer point out where the time is. External 10–25 Hz GPS receivers for tighter sectors are awaiting hardware validation.
- Venue and layout detection is tested on simulated drives over real OpenStreetMap circuits, not yet in a real car. Compatible GPS receivers

FAQ
Auto Sportsland Sunagawa, answered.
How long is Auto Sportsland Sunagawa?
OpenStreetMap maps 6 closed loops at Auto Sportsland Sunagawa, from 1.25 mi to 1.44 mi (2.31 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.
Which direction does Auto Sportsland Sunagawa run?
OpenStreetMap doesn’t record a direction for the main layout at Auto Sportsland Sunagawa. Venues sometimes run both ways. TRACK takes the direction from your first laps.
Can I time laps at Auto Sportsland Sunagawa with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Auto Sportsland Sunagawa and the layout you’re driving from GPS, then times laps and sectors. A phone’s GPS is good for lap times; an external 10–25 Hz receiver tightens sector splits.
Where is the start/finish line at Auto Sportsland Sunagawa?
TRACK estimates the line from the mapped geometry (usually beside the pit lane, or on the longest straight). It isn’t verified on site, so the app asks you to confirm or move it before timing your first session here.
How do I find track days at Auto Sportsland Sunagawa?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar lists its events too. TRACK doesn’t list events itself.
Where can I stay near Auto Sportsland Sunagawa?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Auto Sportsland Sunagawa from OpenStreetMap, with straight-line distances. Book early for big event weekends.
