若狭国
Obama developed as a seaport with connections to the Asian continent even before the start of written history in Japan, and artefacts from China have been found in local tombs from the Kofun period. From the Asuka period and Nara period, salt and seafood from the Obama area were supplied to the Yamato dynasty, and under the Ritsuryō system, Obama was the capital of Wakasa Province. Many temples and cultural remains from the Nara and Heian period are found in the Obama area, and the city labels itself "Nara by the sea" in its tourist promotions. As a result of its location in the Wakasa Province area, which travelers passed through when traveling between China and Kyoto, the area was influenced by Chinese culture for a long period. There are many buildings and houses in the Sancho-machi area of the city whose design was influenced by trade with the Chinese mainland.
