So I was wondering, how do Japanese people greet each other when they are, for
example, writing on a blog or recording a video? My doubt comes from the fact
that their greetings will be directed towards someone who is unknown, and that
the greeting will be seen on a unpredictable time. Someone who accesses the
blog (or watches the video or whatever) could to that at anytime of the day.
Does that even matter? Or one should take into consideration the time when
they're are writing/recording? Or neither?

question
usage expressions
Greeting a person over the internet
As a generic you can't go wrong with こんにちは. For example on Facebook or twitter
I see posts by companies often that start with こんにちは. It depends on the
context, of course, so if there's a situation where time of day is just
understood then you can use that greeting. Or you can give a twist to it and
start with ハロー！

Greetings on the internet are largely the same as those that would be done on
the phone or in person.

> こんにちは with be fine for a friend etc.  
>  お疲れ様です would be fine for a work colleague  
>  はじめまして for someone you are meeting of the first time.  
>  うっす is even acceptable for very casual situations.

I've seen a few bloggers start with this generic combination of all three
standard greetings:

> おはよう、こんにちは、こんばんは。いつみてるか分からないから、あいさつぜんぶ。

To be independent of the time of day (though こんにちは would generally be fine in
internet conversations), another greeting you could use is

> お元気ですか？ロドリゴです。

which is equivalent to "how are you guys doing? This is Rodrigo."

A good reference for you would be a Japanese podcast.

Every Japanese greeting with new people, whether business, audience or casual
encounter, involves,

  1. Salutation Ex: こんにちわ、おはようございますetc.

  2. Self introduction, where you belong, your connection to the group or what you do. Ex: ＡＢＣサイト中国語担当の田中と申します。宜しくお願いします。

Can you be more specific? Keep in mind, for every situation or season, there's
a set routine Japanese people do things. Context is king in speaking Japanese.

Everything depends on the audience.

In Japanese there are two distinct types of speech:

- **Formal speech** , to be used with strangers, people older than you and family members you do not know well.

- **Informal speech** , to be used with close friends, family members and those who are the same age or younger than you.

hello-in-japanese-no-matter-what-the-time-of-day/>

In a blog or video you might want to break the ice with the reader/viewer and
might adopt an informal tone so おはようございます will be おはよう and so...

I can't comment yet, but agree on just using こんにちは.

That's the simplest one, and you see it a lot in written form. On videos or
podcasts, it's a bit more common for people to get more creative with the
greeting.
