Tokyo Alert
According to the Tokyo Metropolitan Government, Tokyo Alert is "an accurate notification of the infection situation in Tokyo and a call for vigilance". The purpose is to issue early warning information and prevent the re-expansion of infection. Tokyo Alert does not impose any restrictions on the lives of Tokyo residents, and is merely a call for vigilance by the city.

On 2 June 2020, Tokyo Alert was issued due to the risk of infection spreading mainly in downtown areas and hospitals at night. The Rainbow Bridge and the Tokyo Metropolitan Government Building were lit up in red. Journalist Toshinao Sasaki said in a radio program, "I wondered what Tokyo Alert was, so I looked it up on a search engine, but there was neither a site nor news that explained what to do." In addition, criticism of Tokyo Alert included that the new standards were difficult to understand.

The Tokyo Alert was lifted on June 11, the 10th day after it was issued. Yuriko Koike announced on June 12 that she would end the Tokyo Alert and phased closure request system. On the 15th, we decided to consider reviewing the criteria for issuing alerts. In the two weeks after the alert was lifted (June 12–25), the total number of infected people was 500, almost double the total of 252 in the previous two weeks (May 29-June 11). The Tokyo metropolitan government was cautious about reissuing the alert, fearing that economic activity would stagnate again.

Tokyo COVID-19 countermeasure site
The Tokyo Metropolitan Government COVID-19 Countermeasures Site is a website published by the Tokyo Metropolitan Government on the spread of COVID-19 infection in Tokyo.

Developed by Code for Japan, a general incorporated association, commissioned by the Tokyo Metropolitan Government. Since its release on March 3, 2020, it has exceeded 1 million PV per day. In addition, although it is unusual for a public institution website, it is open source through GitHub and receives feedback. Taking advantage of its characteristics, many derivative sites such as other prefecture versions have appeared. In addition, Taiwan's Minister of Digital Affairs Audrey Tang participated in the feedback.

It provides real-time information in an easy-to-read, simple design. It is open source and can be used by anyone. It also supports six languages: Japanese, English, Chinese (simplified and traditional), Korean, and simple Japanese. Information such as the status of testing and the number of infected people is displayed in a graph -based design, and the latest news and consultation methods are also explained.

Infection prevention thorough declaration sticker
The Tokyo Metropolitan Government issued the "Thorough Infection Prevention Declaration Sticker" for the purpose of working on the infection spread prevention guidelines for businesses formulated by the metropolitan government. In the media, it is also known as the rainbow sticker. A checklist that businesses should take to prevent the spread of infection is checked on the web and issued online, and it is used as a guideline to show that businesses are working on infection prevention measures. At a press conference on July 15, Koike called on restaurants and other establishments that do not comply with the metropolitan government's guidelines to "avoid using them," and told business operators that they were following the guidelines set by the metropolitan government. As of August 13, about 175,000 stickers have been issued, and the number of stickers has reached about 190,000. Starting on the 3rd, when restaurants and other establishments were asked to operate at shorter hours, the number of stores that put up the stickers gradually increased, partly due to the fact that posting the stickers was a condition for receiving the cooperation money. Koike says, "I want to fill all of Tokyo with rainbow marks, aiming for 1 million copies".

Anyone can print out the stickers by checking the items on the Tokyo Metropolitan Government website. In August, a mass infection was confirmed at a restaurant that posted the sticker, and the Tokyo Metropolitan Government said, "We will check to what extent the guidelines have been followed."

Socio-economic impact
The Tokyo One Piece Tower closed down permanently on July 31, 2020, due to the impact of the pandemic on its management. The 2020 Tokyo Rainbow Pride parade was cancelled.
