The camera shows the Otarumi section of National Route 20 near Minamiasakawa. The road-management still image is useful for checking traffic flow, wet pavement, snow cover, and visibility.

Route 20 is a major road connecting central Tokyo with Yamanashi and Nagano. Around Otarumi Pass it is also used for travel between central Hachioji, Mount Takao, and Lake Sagami. Mountain weather can change even when conditions are clear elsewhere, so check the camera before departure.

Watch for Snow and Icy Pavement on Route 20 at Otarumi Pass

Because the pass is in a mountainous area, winter temperatures may be lower than in central Tokyo, and snow or ice can form. During snowfall, very cold mornings, and on shaded sections, the road may be more slippery than it appears.

Whether traveling from Hachioji toward Lake Sagami or returning from Sagami toward Takao and Hachioji, check the road surface and prepare winter tires or chains when necessary. Do not rely on the camera alone; review weather and official road restrictions too.

What to Check Before Rainfall Restrictions or Road Closures

Mountainous parts of Route 20, including Otarumi Pass, may be subject to traffic restrictions or closure because of heavy rain or snow. On rainy days, watch for standing water, poor visibility, fallen leaves, and possible soil or debris on the road.

The camera shows local conditions, but official road information and updates from the Japan Road Traffic Information Center should be checked for restrictions and detailed traffic conditions. When a typhoon approaches or heavy-rain or snow warnings are in effect, review information before departure and again from a safe place while traveling.

How to Use the Camera Before Traveling Toward Hachioji or Lake Sagami

The camera is useful before traveling from central Hachioji or Mount Takao toward Lake Sagami, and before returning from Lake Sagami toward Hachioji. Traffic often increases around Mount Takao and Lake Sagami on weekends, holidays, and during sightseeing seasons.

Before leaving, compare the Otarumi section with the weather forecast, rain radar, and nearby road cameras. When snow or intense rain is expected, allow extra time and be prepared to avoid crossing the pass if conditions are unsafe.
