Sightseeing Spots

Alongside those in Osaka and Hakata, this is one of Japan's three great Sumyoshi-jinja Shrines (dedicated to the sumiyoshi dieties).
Built by the shogun Hiroyo Ouchi in 1370, this shrine's main hall with its cypress bark thatching has been designated a National Treasure, and viewers can admire the beauty of its unusual 9-ken (a ken being the distance between supporting pillars of the shrine) streamlined roof style (nagare-zukuri).
The Sumiyoshi-jinja front hall, in front of the main hall, was constructed in 1539 with a donation from daimyo Mori Motonari, and is designated as a National Important Cultural Property.
Unlike Osaka's Sumiyoshi-jinja Shrine, Nagato Ichinomiya, this Sumiyoshi-jinja Shrine at which many of history's samurai prayed, the three sumiyoshi deities (Sokotsutsu-no-O-no-Mikoto, Nakatsutsu-no-O-no-Mikoto, and Uwatsutsu-no-O-no-Mikoto) are enshrined together, where their "aramitama," or spirities are enshrined.
More than one Shinto god is enshrined here, including the following.
First Group: Three Sumiyoshi Deities (Sokotsutsu-no-O-no-Mikoto, Nakatsutsu-no-O-no-Mikoto, and Uwatsutsu-no-O-no-Mikoto)
Second Group: Emperor Ojin
Third Group: Takenouchi-no-Sukune
Fourth Group: Emperess Jingu
Fifth Group: Takeminakata

In fact, the Sumiyoshi-jinja Shrine in Nagato Yumoto, is enshrined as a Sumiyoshi god of onsen in Shimonoseki.
