Tokyo Metropolis
proper noun
Remember how 東京 is Tokyo? Add metropolis to it and you get the Tokyo Metropolis.
東京都 is basically one of Japan's prefectures, but they call it a "metropolis" instead. It's the capital and the largest city in all of Japan!
The reading is just 東京 and the on'yomi for 都 (と), which you learned with the kanji. In other words, on'yomi for all three kanji here.
