Why do Japanese greetings talk about the weather?

As far as I know, the weather is the best topic for strangers to talk about.

Usually, the weather will be the opening remarks. Just like eating in China. This is the answer I just saw. Quite reasonable)

Just like Europeans and Americans, Japanese people don't talk about other people's privacy, so the weather is a good greeting topic. The Japanese island country has a maritime climate. It is often sunny in Wan Li in the morning, but it rains cats and dogs in the afternoon. In the past, agriculture, especially fisheries, was closely related to the weather, so people naturally paid attention to the weather changes. And the Japanese don't want to ask too much about other people's privacy, so they ask where you are going. Nothing is appropriate to eat, and the weather has become the best way to greet.

Just repeat what he said in response to this greeting.

For example:

ぃぃぉですね.-はぃぃぉですね

ぃですね.-はぃにですねねね.

ぃですね - はぃににですねね.

よくりますね-はぃよくりすね

In addition, you can also talk about some topics that everyone is interested in, such as:

This year's はがどぃですね.

もぅぉにぃらっしゃぃましたか.
