First, thanks for all the information about the CoronaVirus (COVID-19) here: https://www.nikaidou.com/
In your article, you mentioned a live map for updates, but when I tried to visit there it was under load/broken...
I searched in Google for something that works and shows real data (from the World Health Organization) and found this page:
I suggest adding it as another source to your page, to allow users another option when the first site is overloaded.
BTW you'll notice the number this official tool give are a bit smaller than what you read on the news. That's because the World Health Organization is more conservative into approving each case the news quickly define as Corona Virus. I actually think this is better. People want official serious data and not just headlines that scare them.
Keep up the great work!
