Japanese lecture by Kamonohashi : Which is better?

Hello , thanks for always following me.

Kamonohahsi here.

Recently , many people talk to me on twitter it's so nie and I'm so glad.

I regard all of you is my students!!!(*´∇｀*)

And many students try to talk to me in Japanese !!

like "kon ni chi wa!!" "カモノさん！！"

Good good good!!

And I noticed one thing .

Some students try to talk in friendly Japanese.

for example , when you wanna say "How are you?" you can say

お元気ですか?
(ogenki desuka?)

in Japanese. This is politely way.

One students talk to me like this

お元気か！？
(ogenki ka?)

hm.......^^;

it is not wrong . I can understand.
But actually , its expression is little rude.

～ですか(desuka) , ～しますか(shimasuka)

These are politely way of Japanese talking.

However ,

Subject+Noun＋か(ka)?

This style is rude way.

for example ,

あなたは医者か？
(anata wa isha ka?)
Are you a doctor?

It's not good way.

The best way is

あなたは医者ですか？
(anata wa isha desuka?)

Politely and natural way of saying.

～ますか(masuka)、～しますか(shimasuka)、～ですか(desuka)、～しましょうか(shimashouka)......

The Japanese politely way of saying has many pattern. Please study gradually .

And if you are beginner of Japanese , I recommend you to study (learn) politely way first.Because , friendly(frankly) way is difficult .
(* On my YouTube , I speak Japanese in politely way too.)

Please don't get halfway Japanese but please learn both politely and friendly Japanese surely .
