Interesting site. That's the first time I've actually seen a breakdown in numbers among the different municipalities within Tokyo.

The -ku I used to live in is the hardest hit by total numbers. Maybe not on a per capita basis. I can't tell.
I'm assuming you're referring to Setagaya? Knowing that Setagaya is the most populous ward, I eyeballed it and did a few calculations, and it would seem that it probably is the hardest hit per capita, though not by a particularly huge margin.
Setagaya-ku: 939,099 / 349 = 1 per 2,690
Nerima-ku: 742,652 / 157 = 1 per 4,730
Suginami-ku: 585,470 / 173 = 1 per 3,384
Ota-ku: 739,575 / 140 = 1 per 5,283
One thing that kind of surprises me about the map is the huge drop-off once you get outside the 23 wards. I live in the Mitaka/Kichijoji area, the latter of which especially has regularly been taking flack on the news for a relatively steady stream of people in the shopping arcades even since the state of emergency was declared. Yet according to these figures, we're looking at:
Mitaka-shi + Musashino-shi:
340,868 (192,518 + 148,350) /
40 (25 + 15) = 1 per 8,521
(I combined the two cities since they essentially bleed into each other, straddling the JR Chuo Line, and even together have a combined land area considerably smaller than any of the wards above.)
Going out further west (past Hachioji and Tachikawa), you get the rural outskirts of Tokyo, which is another story, but the general population density and composition of Mitaka-shi/Musashino-shi isn't really all that different from neighboring Suginami-ku/Setagaya-ku/Nerima-ku, so I can't help but wonder if the disparity is due to heavier testing within the 23 wards, or what.
