Tohoku has a reputation for being an icy region, but its summers are hot. Its population is over 9 million people, including several large cityballs such as Sendaiball and Moriokaball.
Tohoku has a dialect of Japanese known as Tohoku-ben which is strong enough to make communication a little difficult for people from other regions like Tokyoball.
Tohoku-ben becomes more pronounced as it gets closer to rural areas. Many people in these regions are intimidated when using the dialect outside their hometown, because they have the stigma of being from the countryside (if Japanese is compared to American English, Tohoku-ben may be seen as a equivalent to the Appalachian accent, due to being associated with rural areas).
Tohoku is known for its winter sports, matsuri (festivals), hospitality and excellent food.
