Tokyo was a Geography and places good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

This article is written in American English, which has its own spelling conventions (center, color, defense, realize, traveled) and some terms may be different or absent from other varieties of English. According to the relevant style guide, this should not be changed without broad consensus.
The article says that Tokyo is "the most populous city in the world with a population of over 14 million residents as of 2023". That is misleading though, because those 14 million people do not make it the worlds most populous city. That claim can only be made, if you look at the metropolitan area, which is mentioned in the next sentence: "The Tokyo metropolitan area, which includes Tokyo and nearby prefectures, is the world's most-populous metropolitan area with 40.8 million residents as of 2023.". If the title "most populous city" is just measured by metropolitan area, it does not make sense though to mention the title "most-populous metropolitan area" in the next sentence. So those two sentences should be changed to make it clearer, that Tokyo is the 11th largest city, but the Tokyo metropolitan area is the largest metropolitan area. If you take the metropolitan area as a measure of city size, the problem is, that Yokohama is part of that area. Yokohama itself is a city of 3.8 million people and those people can't be counted both as residents of Yokohama and Tokyo. I have a theory where this mistake came from. The the most populous city in the world article by default sorts the most populous cities by their metro area. If you sort that list by the population of the city proper, you will see that Tokyo will drop to 11th.
There are often heated discussions of the metropolitan area is a part of a city. There are arguments for both sides. Metropolitan areas often technically work as a giant city and the city borders are just political. However a resident of Jersey City would probably shoot you if you told him that Jersey City is a part of New York City. Wikipedia could stay out of that discussion by mentioning both (11th most populous city by city proper and most populous by metropolitan area).
In Tokio the "city" definition is even more complicated, as the districts of Tokyo are also called "cities". For example Shinjuku City, Shibuya City, Minato City and Toshima City. Those districts are in many ways quite autonomous and function like real cities. They even compete against each other. Skyscraperfan (talk) 10:29, 23 December 2023 (UTC)[reply]
The recent change of the lead paragraph has inserted mention that Tokyo is the "second largest national capital," which is an interesting but unusual metric to include in the introductory paragraph of a city article. (Note also that it is only true based on city proper population.) It seems possible that the editor who made this change is motivated by a desire to highlighting that Beijing is the world's most populous national capital by city proper population. I propose to move this fact to the demographics section or eliminate entirely as it is not appropriate or typical for the introductory paragraph.InformationVolunteerInformationVolunteer (talk) 13:09, 27 August 2024 (UTC)[reply]
Hi, I noticed a formatting error in the city template. All the population data is from 2023 except for one, which was has "(as of 2024)" appended to it. Unfortunately the template has formatted this to "(as of 2,024)". I'm not sure what to do about this. As long the data is from a different date from the rest, this seems necessary, so I don't think it can simply be removed. 114.23.161.152 (talk) 09:35, 10 September 2024 (UTC)[reply]
Hello IP address. The 2024 population data for August has been released so, I've updated the data and removed the (as of 2024) from the template as its no longer needed.
