You say this to someone when they come into your home after you have exchanged greetings. The visitor responds by saying "OJAMA SHIMASU."
"Doozo ohairi kudasai." = Please come in.
"Ojama shimasu." = Thank you.
Note: In the system of romanization used in this section, "ee" is not pronounced like feet. Instead, it means that the vowel sound "e" as in pet is prolonged. In the same manner, "oo" is pronounced not like shoot but as the "o" vowel, similar to pork, pronounced twice as long.
