Japan Prefectures Quiz: Name All 47 Prefectures

Japan divides into 47 prefectures. This quiz shows a blank map of Japan. You type the name of each prefecture, and the map colors that prefecture in place.

The progress panel groups the prefectures into the 8 traditional regions, from Hokkaido in the north to Kyushu and Okinawa in the south. Use the groups to find the parts you still miss.

How to play

• Type prefecture names in any order. A correct name colors the prefecture on the map at once.
• You can start to type right away. You do not need to click the answer box first.
• Macrons are not required. "Osaka" counts for Ōsaka, and "Oita" counts for Ōita.
• The suffix is not required. Type "Aichi", not "Aichi Prefecture".
• A timer tracks your run. The quiz saves your best score and best time.
• If you are stuck, use the give up button. The map then shows the prefectures you missed.

What counts in this quiz

• All 47 prefectures, in their common English spelling.

What's not included — and why

• Cities are not answers, unless a prefecture has the same name. Yokohama, Kobe and Sapporo do not score.
• The 8 regions are not answers. Kanto and Kansai are group names in the panel, not prefectures.

Good to know

• Hokkaido is the largest prefecture. It is about 22 percent of Japan by area.
• Kagawa is the smallest prefecture by area, and it faces the Inland Sea.
• Tokyo has the most people. More than 13 million live inside the prefecture.
• Four names differ from the plain "ken" form: Tokyo is a "to", Hokkaido is a "do", and Osaka and Kyoto are each a "fu".
• Okinawa is the southernmost prefecture. It lies closer to Taipei than to Tokyo.
