The Engishiki records that Nojiri Station kept 10 post horses, 3 relay horses and 5 boats. The town thinks it stood at an old fort site where a tributary joins the Mogami River. A 2007 prefectural dig found Heian-period buildings, including ones with a hisashi (side aisle).
02 ／ Winnowing baskets
A prefectural video record calls the itaya maple used for the baskets hene-gi, and shows it split thin into hene strips to weave ikada baskets. Two bamboo rods form the handle. The town calls the Showa 30s (1955-1964) the peak of basket making.
03 ／ River port
According to the town, Oishida's river port (kashi) began around the Muromachi period and was busiest around the Genroku era. A shogunate boat office was set up in 1792, and a gate and a storehouse have been recreated at the Mogami River boat office site.
