Japan · Prefectures

Japanese prefectures, found on the map

Forty-seven prefectures, from Hokkaido at the top of the map to Okinawa 3,000 kilometers away at the bottom left. The islands themselves give you most of what you need: the run is long, but a prefecture is either on the Pacific side, the Sea of Japan side, or the inland sea between them, and that is usually enough to narrow it.

No labels on the map and nothing to pick from a list. The question names a place and you point at it, and every answer comes with a paragraph about what you just found.

47 to find, 8 a run.

6 rounds, 6 of 8 to pass each. Pass one and its places are yours.

What the map tells you about each one

The paragraph the game shows when you find a place, for all 16 of the ones written by hand. Reading them first is not cheating.

Hokkaido
Hokkaido is about 78,400 square kilometers, more than a fifth of the country, and holds about four percent of its people. It was Ainu land and was only settled from the mainland in earnest after 1869, which is why its towns are on grids and its farms are the size of American ones. It is the one prefecture whose name does not end in ken, fu or to.
Tokyo
The prefecture holds about 14 million people and the built-up area around it about 37 million, which is the largest urban area in the world. It also administers two chains of islands out in the Pacific, the further of which puts a rock of 1.5 square kilometers 1,850 kilometers southeast of the city. Edo was renamed Tokyo, the eastern capital, in 1868.
Osaka
Osaka is the second smallest prefecture by area and the third most populous. It was the merchant city rather than the court city, the place the rice tax of the whole country was traded, and it was called the nation’s kitchen for it. The dialect, the comedy and the reputation for talking about money all come from that.
Kyoto
Kyoto was the imperial capital from 794 to 1868, which is a thousand and seventy-four years in one place. It was on the target list for the atomic bomb and was taken off it, and it came through the war almost undamaged, which is why seventeen separate sites in and around it are on the UNESCO list.
Okinawa
The Ryukyu Islands were an independent kingdom trading with China and Southeast Asia until Japan annexed them in 1879. The battle fought here from April to June 1945 killed something like a quarter of the civilian population. The United States administered the islands until 1972, and about seventy percent of American base land in Japan is still on them.
Hiroshima
The city is built on the delta of the Ota, which is what the name means: a wide island. The bomb dropped on 6 August 1945 killed tens of thousands outright and roughly 140,000 by the end of the year. The floating torii of Itsukushima stands offshore in the same prefecture and was untouched.
Nagasaki
For over two hundred years the only Europeans allowed in Japan lived on Dejima, an artificial fan-shaped island in Nagasaki harbor about 120 meters across, and everything the country learned of the West came through it. The prefecture has around 970 islands, more than any other. The second atomic bomb fell on the city on 9 August 1945.
Aichi
Aichi has the largest industrial output of any prefecture, most of it built around Toyota, whose home town changed its own name to the company’s in 1959. It is also where all three of the men who unified Japan in the sixteenth century were born, which is an unusual thing for one province to be able to say.
Kanagawa
Commodore Perry anchored off its coast in 1853, and the treaty that opened Japan was signed at Kanagawa the following year, which turned a fishing village called Yokohama into the country’s first foreign port. Kamakura, further down the same coast, was the seat of the shoguns from 1185 to 1333.
Fukuoka
Fukuoka is closer to Busan than to Tokyo, and everything that ever arrived in Japan from the mainland arrived roughly here: rice, writing, Buddhism. The Mongol fleets landed on Hakata Bay in 1274 and 1281 and were broken the second time by the storm the Japanese named the divine wind, kamikaze.
Nara
Nara was the capital from 710 to 784, the first fixed one the country had, and the temple built there holds a bronze Buddha of about 500 tonnes in a hall that is among the largest wooden buildings in the world. The deer wandering the park around it are protected as messengers of the local gods.
Niigata
The winter monsoon crosses the warm Sea of Japan, picks up moisture and drops it against these mountains, which makes this one of the snowiest inhabited places on earth: several meters on the ground is a normal winter. The rice grown on the plain below is generally reckoned the best in the country.
Nagano
Nagano holds most of the Japanese Alps and more of the country’s three-thousand-meter peaks than anywhere else. It hosted the Winter Olympics in 1998. It touches eight other prefectures, which is more than any of them, and it is one of only eight with no coast at all.
Fukushima
It is the third largest prefecture and is cut by two mountain ranges into three strips with quite different weather. The earthquake of 11 March 2011, magnitude 9.0, sent a tsunami up to about 15 meters onto this coast; it killed most of the roughly 18,000 who died that day and flooded the reactors at the Daiichi plant.
Shizuoka
Mount Fuji stands on its northern border at 3,776 meters, and the bay below it, Suruga Bay, is about 2,500 meters deep, so the ground drops six kilometers over a horizontal distance of fifty. The prefecture grows around forty percent of Japan’s tea, and the old Tokaido road along its coast is the one in Hiroshige’s prints.
Kagawa
Kagawa is about 1,877 square kilometers, smaller than any other prefecture and smaller than several single cities elsewhere in Japan. It is known nationally for udon, eats more of it per head than anywhere else, and the first of the three bridge routes across the inland sea came ashore here in 1988.
Before you start

How this one works

How many prefectures are on the map?

47. Every one of them is on the map, and a run asks 8 of them. Pass a round and the places you found in it drop out of the pool, so the next run is what you have left.

What is a round?

8 of them, and 6 right passes it. 6 rounds cover the whole map, and the counter at the top of the Japan page counts the ones behind you. Passing is what banks a round's finds: miss the mark and nothing is taken off the map, so every place that round asked about is still there to be asked again. Nothing you have banked is ever asked again while anything is still unfound, so the last round of the map is however many are left, and three quarters of that passes it.

Can I start the map over?

Yes. "Reset this map" under the counter puts all 47 back in the pool and sets the rounds to zero the moment you press it, so the whole map is there to be found again from nothing. It clears this map only; the other maps of Japan keep their progress.

Do I need an account?

No. The game plays in the page, and a guest's progress is kept in their own browser. Signing in carries it between devices and earns XP for a run.

What happens when I get one wrong?

The map names what you actually hit, then lights up the right answer in green and tells you something about the place. Missing one is how most of this map gets learned.
