Barometric Pressure in Japan

We monitor barometric pressure across 19 cities in Japan, giving you up-to-date insights into local weather patterns.

Whether you're tracking pressure changes for health reasons, planning outdoor activities, or planning a fishing trip, our data is tailored to conditions in Japan, with detailed readings city by city.

Japan Barometric Pressure Map

Depending on how many places we monitor in Japan, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.

Here you can see which cities experienced the biggest and smallest changes in barometric pressure today. This helps highlight areas with the most stable or unstable weather patterns.

Most volatile

Least volatile

How is it calculated?

Our volatility “beta” number is generated by an algorithm that analyzes hourly barometric pressure changes. It looks at how much the pressure fluctuates from hour to hour. A beta of 0 means no change, perfectly stable pressure. The higher the decimal value, the more variation there has been throughout the day or over a longer period.

Weather Systems

Japan is affected by large weather systems like the Siberian High in winter and the Pacific High in summer. These systems create areas of high or low air pressure that move across the country, causing changes in wind, clouds, and rain.

Geography

Japan’s mountains and long, narrow islands change how air pressure spreads. Mountains block or channel winds, so air pressure can be higher on one side and lower on the other. Coastal areas feel changes faster than places sheltered by mountains.

Seasonal Cycles

In winter, cold air from Siberia creates high pressure over northern Asia and pushes cold winds toward Japan. In summer, warm air from the Pacific forms high pressure and brings hot, humid weather. Spring and autumn have shifting pressure as these systems switch places.

Climate Change

Climate change is making air pressure patterns less predictable. Warming oceans and air lead to stronger storms and heavier rainfall. High and low pressure areas may last longer or move differently than before, which can cause more extreme weather in Japan.

Places in Japan

You can find your city in the lists below, by using our search, or on the Japan Pressure Map above. We're tracking barometric pressure across multiple locations in Japan to keep you informed.

Each city includes a pressure status showing whether it's currently high, normal or low, along with two volatility values: one for today and one for the full period, usually 14 days. These help you see how much the pressure is changing over time.
