Engrish is unusual English usually used in Japan or eny other East asia nation.
All Japanese student are study to Engrish from Japanese native Engrish teacher.
The Japanese can recognize only five Vowel: [a], [e], [i], [o] and [u]. Sound of [a] is pronounced with the mouth closed, so, e.g., the word "and" pronounced by native Japanese may be heard like "und" (in X-SAMPA, [Vnd], not "und [unt]" of German).
This is why English of Japanese speaker is called as Engrish.
In Japanese, Only liquid consonant is  (X-SAMPA). Thus, the Japanese can't recognize the difference bitween [l] and [r].
By the way, , the Japanese only liquid consonant, sounds like fast "T" of American English such as "better" or "city".
