Within the map, the area outlined in red marks Ishikawa Prefecture. Ishikawa can be broadly divided into two parts, the Noto region (能登地方) to the north and the Kaga Region (加賀地方) to the south, with the city of Kanazawa (金沢), the prefectural capital, as effectively the north border of Kaga. Noto has a higher ratio of narrow mountain roads, the map explains, many of which have been blocked or damaged by the quake, causing extensive traffic jams in the area. For this reason, use of private cars is not recommended, in order to leave as much of the road network's capacity for residents, relief staff, and essential workers. The map also subdivides Noto into Northern Noto (能登北部) (also called Inner Noto [奥能登]), and Southern Noto (能登南部), shown by the red and orange areas on the map. Out of the two, Northern Noto has been especially affected by the quake, as the epicenter was off the northern tip of the coastline. On the other hand, things in the Kaga region, shown in bright green, are pretty much as normal, the map says. Almost all shops and restaurants are keeping to their regular business hours, and sightseeing attractions remain open. The Hokuriku Shinkansen, which connects Tokyo and Kanazawa, is running as normal, flights are arriving and departing regularly at regional air hub Komatsu Airport, and roads remain open to motorists.
