国・地域を見ていく。
当然、日本・韓国・中国と近い都市が並ぶ。

中国は広い。
63位のウルムチの後、すぐ68位にインド・コルカタが入ってくる。

北米最近の都市バンクーバーの前後に
ロシアのモスクワとサンクトペテルブルク。
そして、オーストラリアのブリスベーンとシドニー。

アフリカ最近の都市カイロの前後はロンドンにパリ。

南米は遠い。
最遠の都市はブラジルのポルト・アレグレ。
メガシティに限ればリオデジャネイロになる。

ここで正距方位図法の地図を2つ。
東京中心とその対極中心。
アジア、オーストラリアはこちら側。
南極、南米、アフリカは反対側。
ヨーロッパと北米はちょうど中程でどちらの図にも表れてくる。

Tokyo

Antitokyo

さて、では、人口の重みを掛けてみよう。
ここでは人口/東京からの距離と言う指標を使う。
結果は以下の通り。

割と良い感じに有名な都市が並ぶ。
まあ、31-40位ぐらいまではおなじみになりたい都市ではないだろうか。

なお、227位に最遠のポルト・アレグレが来たので
それ以下は非表示とした。
