I have long thought that Tsurukawa, Machida City, Tokyo, where I used to live,

"resembles the Crimea Peninsula".

-----

Comparing the maps,

"Kodomo no kuni" and "Sebastopol"

"Midoriyama Futsal Park" and "Eftparia"

I feel they apply.

Well, Tsurukawa has no sea (Black Sea).

Not only the Tsurukawa district, but the entire Tama area seemed to have a very "unnatural topography" for an administrative district of Tokyo.

-----

So, I did some digging, I found the following line.

"On April 1, 1893, the three Tama areas (Nishitama, Kita-Tama, and Minamitama) were transferred from Kanagawa Prefecture to Tokyo Prefecture in order to secure a water source and control water quality for Tamagawa Josui, Tokyo Prefecture's water supply"

However, I thought 'Isn't that logic a bit of a stretch? (absolutely impossible for Tsurukawa area)" So I looked further and found it.

"It is believed that this was a measure to weaken the influence of the Liberal Party by transferring the three Tama areas (Nishitama, Minamitama, and Kitatama), which had been the center of the Liberal Civil Rights Movement, from Kanagawa Prefecture to Tokyo Prefecture."

See? I knew it!

And, it seems that

"At the time, the Liberal Party members of the prefectural assembly strongly opposed the transfer to the Tokyo Metropolitan Government"

-----

I looked into it further--

Ishizaka Masataka (1841-1907), the supreme leader of the Mittama Liberal Civil Rights Movement, was first elected to the House of Representatives in the first general election (Kanagawa Prefecture primary election, Kanagawa Ward 3).

However, he was elected for his third and fourth terms in Tokyo's 13th ward.

In other words,

"The government was trying to cut off the opposition (Liberal Party) by forcing them to change their constituencies"

This seems to have been the purpose behind the transfer of the Tama area to the Tokyo Metropolitan Government.

In any case, if there is a "strangely shaped administrative district," whether it is a state or a municipality, it is a good idea to suspect "political strife (or war) in the past" first.
