Iwate Prefecture

It's easy to understand that Hokkaido is the largest, but when it comes to the second largest, it's probably not very well known, is it? The next largest is Fukushima Prefecture, followed by Nagano Prefecture.

Nagasaki Prefecture

Doesn’t it feel like Okinawa and Hokkaido would have the most? The correct answer is Nagasaki Prefecture, which has a whopping 1,479 islands. In second place, by a narrow margin, is Hokkaido with 1,473 islands, and third is Kagoshima Prefecture with 1,256.

Tottori Prefecture

According to the Basic Resident Register data for 2022, Tottori Prefecture ranks first, followed by Shimane in second, Kochi in third, Tokushima in fourth, and Fukui in fifth. While Tokyo, with the largest population, has 13.79 million people, Tottori Prefecture has a population of 550,000.

Tokyo Metropolis

When we hear “southernmost” and “island,” we can’t help but think of Okinawa or Kyushu, but the answer was Tokyo. It belongs to Ogasawara Village in Tokyo, and it’s as far as 1,700 km from central Tokyo; I hear it takes four days one way by ship.

three

The correct answers were three: Ishikawa Prefecture, Kanagawa Prefecture, and Kagawa Prefecture. I thought there were many more, but it turns out there are only three.

Shiga Prefecture

The answer is Lake Biwa in Shiga Prefecture. For people in the Kansai region, it’s a familiar large lake that serves as a source of domestic water and a place to enjoy water activities in the summer. Second is Lake Kasumigaura in Ibaraki Prefecture, and third is Lake Saroma in Hokkaido.

Kagawa Prefecture

Don’t many people picture urban areas—like big cities and tourist spots—as having small land areas? In second place is Osaka Prefecture, and in third place is Tokyo. Osaka and Tokyo may be small in area, but they rank high in terms of population, don’t they?
