Why are there so many Vending Machines in Japan?

Japan is an unique country with it's unique culture one of the weirdest inventions like
UMBRELLA TIES
And
SQUARE WATERMELONS?

But if you ever go to Japan, you will see Vending machines, a lot of vending machines, some stores only contain vending machines, At a little over 5 million vending machines, that there's so many vending machines there's around 1 vending machine for every 23 people that live in Japan.
And the vending machines in Japan sell pretty much everything from soft drinks, coffee, candy and sandwiches to hot foods, cigarettes and booze.

Thats a lot of vending machines but why?

The reason for their high amount of vending machines in every city from Kagoshima to Hokkaido is because of it being really cheap, because the cost of labour is almost none with a high amount of money earned from it. It's also because it can be really hard to get anyone to work or sell stuff in Japan because of Japan's declining birthrate, aging population, and lack of immigration which makes any kind of labour costly and scarce.

And because of their high density of 127million in a country the size of california. Japan is one of the most dense areas in the world.

But also because of Japans extremly low homicide or crime levels which allows vending machines to be placed pretty much anywhere with low chance of anyone trying to steal anything in the vending machine without actually paying.

Japan also bearly uses credit cards and only uses cash which makes it easier to buy anything from a vending machine.

And we can't forget japans fictation with automation. Vending machines are automatic, i don't think i had to say that. if i just blew your mind well, you learn something new every day.
