Edokko
Edokko (江戸っ子, literally child of Edo) is a Japanese term referring to a person born and raised in Edo (renamed Tokyo in 1869). The term is believed to have been coined in the late 18th century in Edo. Being an Edokko also implied that the person had certain personality traits different from the non-native population.
Today, the definition of "Edokko" may vary. The Japanese dictionary simply defines it as one who was born and raised in Edo or Tokyo. However, popular definitions of "a true Edokko" include the following:
a. One who was born and raised in Edo/Tokyo to parents who both were also born and raised in Edo/Tokyo. (If one parent was not born and raised in Edo/Tokyo, then the child would not be a true Edokko, and was called madara ["striped"].)
b. One who was born and raised in Edo/Tokyo to a family lineage spanning back three or four generations in Edo/Tokyo.
