What are the stereotypical qualities of a gaijin trying to speak/write Japanese to a Japanese person?


There are plenty of stereotypical qualities of a Japanese speaking person
trying to speak English, so, would I be correct in assuming the reverse is
also the case, and if so, what would the most notable features be?

I ask this both out of curiosity and on the off chance I ever need to actually
try communicating with people in a way that doesn't result in my casual
humiliation.




I'm not sure if this is within the scope of your question, but the following
is about _highly stereotyped_ traits of "gaijin-speech" found in manga and net
forums. They are explained in pages like

_not_ reflect how foreigners speak Japanese in reality. Unsurprisingly, some
of them are rude or displeasing especially to the users of each language.

Western speakers trying to speak Japanese:

  * Wrong intonation, accent, vowel length, double consonant: ニ **ホー** ンゴ **ワー** カリマセーン, オモシローイ **デー** ス, ビ **クー** リデス
  * Trilled/rolled ラリルレロ sounds
  * Overuse of personal pronouns: ワ **ター** シ, ア **ナー** タハー
  * Unconditional sentence-end です: 見るデス, 行けデス
  * Overuse/misuse of sentence-end ナ, ヨ, etc: 本当ヨ!
  * Use of katakanized English when excited: オーノー! ワーオ! ホワット!?
  * Use of ミー and ユー as person pronouns: [ユーは何しに日本へ?](https://en.wikipedia.org/wiki/Why_Did_You_Come_to_Japan%3F)

Chinese speakers trying to speak Japanese:

  * アル, ネー or ヨー at the end of every sentence: 私は中国人アル  
(This is based on [a pidgin Japanese
language](https://en.wikipedia.org/wiki/Kyowa-go) but later established as
role language. アル was rather common 30 years ago or so, but today it's usually
a rude way to simulate Chinese accent.)

  * Insertion of の between a verb and こと, とき, etc: 食べるのこと, 見るのとき

Korean speaker trying to speak Japanese:

  * ニダ (Korean copula similar to Japanese です) at the end of every sentence: 私は韓国人ニダ  
(This is almost always rude.)
