Geography: Japan and the World
This domain tests how Japan's location, landforms, climate, and regional differences connect to maps and to the wider world. Questions often ask you to read a map scale, compare climate patterns, or explain why a region's agriculture or population is distributed as it is.
Core rules and concepts
- Japan stretches roughly from 20°N to 46°N and from about 123°E to 146°E. Its latitude helps produce clear seasonal change, but latitude alone does not explain local climate.
- About three quarters of Japan is mountainous. Plains are small and crowded, so population, farming, and transport concentrate on coastal lowlands and deltas.
- Seasonal winds matter. Winter northwesterlies pick up moisture over the Sea of Japan and drop heavy snow on the Japan Sea side; summer southeasterlies bring rain and typhoons.
- The Japan Alps create a rain shadow. Nagasaki and other Kyushu areas are warmer and wetter than inland basins such as Matsumoto.
- Map scale is a ratio. On a 1:25,000 map, 1 cm represents 25,000 cm, or 250 m.
- Japan Standard Time is based on 135°E, UTC+9. Places 15° west are usually one hour earlier.
Worked example
A map has a scale of 1:25,000. A straight road measures 6 cm. Convert the scale first: 1 cm = 25,000 cm = 250 m. Then multiply: 6 × 250 m = 1,500 m, or 1.5 km. Do not multiply by 25,000 and report centimetres as kilometres.
Traps that cost marks
Mixing latitude and longitude; forgetting that scale units must be converted; assuming all of Japan has the same climate; and treating seasonal wind direction as constant all year. Also check whether a graph shows average temperature or precipitation, and whether a map is topological rather than to scale.
