According to a survey conducted by the Nippon Research Center in October 2019, around 33 percent of people in Japan stated that they often read manga or watch anime.
TL;DR: Yes. It is safe but with a catch. Streaming services that have a license to broadcast content within Japan such as Niconico are ideal. Streaming services meant to distribute anime abroad such as Crunchyroll and Hulu are also legal to view in Japan.
Manga and anime are perhaps Japan's biggest cultural export – and they make up one of the most recognizable art styles on the planet. Since the nineties, when everyone in the western world was suddenly talking about Pokémon, Digimon, Yu-Gi-Oh!, and Dragon Ball Z, anime has become something of a household term.
The overall frequency of anime viewing is 'once a week or more' for 57% of respondents. 17% watch 'once in 2-3 months', 16% watch 'less than once in 2-3 months', and 10% 'don't watch anime works at all'. This result means one in two people watch anime once a week.

Yes, but it does not mean many Japanese adults watch such anime titles. They are geard only towards anime-addicted adults. Many Japanese adults even don't know existence of such anime. It depends just on the person.
Anime has become more popular overseas in recent years due to a shrinking Japanese population leading to an increased export-minded trade. This has meant that anime producers have started to make content more suited to Western tastes, as well as producing anime overseas as it is much cheaper.
In Japan, "anime," pronounced "ah-nee-meh," are cartoons that date back to the early 1900s. A related Japanese term is "manga," which refers to animated cartoons and comics in general, not necessarily in the anime style. Outside Japan, the terms manga and anime are often used synonymously.
But as it becomes more profitable and popular, anime has proven to be a boon to the diversity of cultural conversation. A form of entertainment from another culture is having a positive impact on our culture, which enables our society to break down the borders dividing us and become more diverse and tolerant.
It's more popular in Japan by a country mile, made by the Japanese for the Japanese. That's the way most Japanese things work, they're very focussed on what their own country's consumers want first, everyone else comes a very distant second.
There is no such thing as being too old to watch anime. Anime is a term that refers to a bunch of animated works coming from Japan. There are various genres directed at various demographics. Fortunately, age is not detrimental in deciding whether or not we like something!
Yes its perfectly fine to watch anime as an adult.
