Hello, I found a site where I can customize the map by myself today, so I will introduce it.The name is Explore Styles!
Snazzy Maps - Free Styles for Google Maps
Snazzy Maps is a repository of different color schemes for Google Maps aimed towards web designers and developers.
snazzymaps.com
It is this site, but it is all In English.However, I think that it understands somehow.You can use it if you find a map of your ideal design in English in the search window.By the way, customized maps can also be displayed on your site.It is a convenient site to put a different map on your site.
