Ōyaren

Ōyaren [往上迂; おうやれん] were national roads and highways mostly constructed in the 14th century. They had important roles in opening up once-isolated areas of Kanton and increasing the amount of travel within the country. Using ōyaren, goods and cargo could be transported much more efficiently, and travelers were able to map out their journeys more easily. There were a total of around fifty ōyaren built nationally, with six main routes being the most-used.
Many highways and railway lines in modern Kanton follow the old routes established with ōyaren and carry the same names. The earlier highways radiated from the old capital Jūkei [優缶], often spreading to other major cities in all directions, with smaller roads branching off to other more secluded areas.
== The six main routes ==
The six main ōyaren used most often by travelers were:
* Daiōren [大往迂] which led southwards from Jūkei.
* Shisairen [尔筌迂] which ran along the east coast and up towards modern-day Ōchome Prefecture.
* Zōchiren [坎欠迂] which ran from Ōchome north towards modern-day Meikai.
* Yuzōren [丐坎迂] which branched from the Zōchiren highway into modern day --- Prefecture.
* Kan'ōren [東往迂] which led north-west from the old capital to modern day --- Prefecture.
* Zaikan'ōren [再東往迂] which continued from Kan'ōren northwards.
There were two lesser routes not included on this list which acted as connecting highways between the old capital, Yuzōren and Zaikan'ōren respectively. They are marked on the provided map.
