Take a look at a map of the world. The 40th parallel north runs just north of Morioka and Akita in Japan and stretches to Turkey – past Ankara – via the Central Asian city of Samarkand, Uzbekistan. Meanwhile, the 25th parallel north passes Okinawa Prefecture and goes through Karachi and Riyadh and south of Cairo. The 30th parallel east is seen west of Cairo and the 75th parallel east appears east of Islamabad.
