The "Takatoro (lantern towers)" placed at the ends of the seawall served as lighthouses, and rise to a height of 6.18 meters; standing as modern day testament of the prosperity of those times.

千砂子波止 (ちさごはと) の鎮守として、大阪の豪商により 1830 (文政 13) 年に建立された全国的にも数少ない「住吉造り」の神社です。
境内の埋め立てでは、御手洗にある若胡子屋など茶屋の遊女たちが砂持を行いました。
遷宮式でも、花魁道中を行い竜宮城の様子を演じるなど、住吉神社の造営事業に彩りを添え、玉垣に刻まれた源氏名の数々を見れば、その献身ぶりがうかがえます。

The village shrine to Chisagohato was built in 1830 (Bunsei period year 13) by a wealthy Osaka merchant, and constructed in the unique "Sumiyoshi-zukuri" architectural style, of which only few examples can be found nationwide. Courtesans from teahouses, such as the Wakaebisuya in Mitarai, would perform the Sunamochi folk song within the grounds of this reclaimed land. During ceremonies installing deities in the shrine, a procession of courtesans would perform dances such as the dance for the Palace of the Dragon King, bringing a festive air to the construction work being performed on the Sumiyoshi Shrine. A glance at the large number of the professional names of said hostesses and geisha etched into the tamagaki (the decorative fence that surrounds the Shinto shrine) indicates the importance of their contributions.

「満舟寺」は、かの平清盛公が上洛の途中にこの付近で嵐に遭い、一心不乱に祈りを捧げたところ晴天となったため、そのお礼として草庵を建て、行基作の十一面観世音を安置したのが始まりと言われています。
この石垣は、羽柴秀吉が四国征伐の際に加藤清正が築造したと言われており、戦国時代の石組みの特徴を持つ安芸灘島嶼部では大変珍しい石垣です。

The "Manshu-ji Temple" traces its origins to a moment during Taira no Kiyomori’s (a government official) pilgrimage to the capital (Kyoto in that time), when he took shelter in this area during a heavy storm. After praying fervently, it is said that the skies parted to provide clear weather, and he constructed a thatched hut on the spot in gratitude, which then became a temple when an Ekādaśamukha (Eleven-Headed Kannon) was installed by the Buddhist monk Gyoki. The stone wall here was said to have been constructed by Katō Kiyomasa at the time of Hideyoshi Hashiba’s invasion of Shikoku, and is a very rare example of distinct stone masonry that was characteristic of the Akinadashoto island territories during the Sengoku period. The burial mounds and the very uncommon turtle-shaped gravestones, built for local haiku poets are some of the many worthwhile sights.

「大東寺」は、江戸時代に本堂が建てられた「登光寺」と明治期に若胡子屋の建物の一部を本堂にした「隆法寺」の 2つの寺院が合併して「大東寺」とされています。
本堂には、京都の彫刻師が彫ったという、極楽に住むという上半身天女の鳥と竜の欄間などがあります。

The "Daito-ji Temple" is comprised of a two temples: "Toko-ji Temple", the main temple was constructed during the Edo period; and "Ryuho-ji Temple", which used a portion of the Wakaebisuya building to create its main hall during the Meiji period. The main temple hall holds artwork said to have been created by a sculptor from Kyoto, which includes a half-bird heavenly maiden said to reside in the Buddhist paradise, and a transom decorated with a dragon carving.

The "Kyu-Shibaya Jyutaku (the former Shibaya Residence)" was a house built during the Edo period where Tadataka Ino lived while he surveyed the Seto Inland Sea. A portion of the grand construction of this building is depicted in the "Tadataka Ino Mitarai Survey Plan," of which only two remain. The house also served as a place of rest for Hiroshima feudal lords on their visits to the island. After the end of the Edo period, it successively served as a rice wholesale store, a seller of ship fittings, and a hardware store until the 1970s.

畳敷きの客席など内部が公開されており、イベント会場としても活用されています。映画やドラマの舞台などにもなりました。

The "Otome-za (Virgo) Theater" was built in 1937 at a time when there were no theaters in Mitarai. The then modern theater building attracted much attention, due to the fashionable, contemporary architectural style it was bulit in. After the war, until the late 1950s-early 1960s it was remolded into a much loved movie theater, and after being put through a variety of other uses, was eventually restored to its past glory. The tatami mat seating area inside is open to the public, and the theater is still used as a venue for events. It has also served as a stage for movies and TV dramas.

御手洗の町並みを南に過ぎると、公園への入り口があります。展望台からは、町並み越しに、アーチ橋と島々がつくりだす多島美と来島海峡から四国へ続く景観がパノラマとなって広がります。みかん畑沿いの遊歩道をいくと、散策の楽しみを体感するうちに御手洗の町並みに抜けていきます。

The entrance to the park is past Mitarai to the south. From the lookout, visitors can enjoy a panoramic view of the Kurushima Channel to Shikoku across the town, the arched bridge, and beautiful islands. If you explore the trail along the tangerine orchards, you will eventually arrive back in Mitarai.

An arch bridge crossing the prefectural border connecting the Akinada Tobishima Kaido.

The Okamura Bridge is Japan’s only agricultural bridge that crosses prefectural borders over the sea. For this reason, there is a line marking prefectural boundaries on the bridge. Osakishimojima Island starts in the city of Kure, Hiroshima, while Okamurajima Island side is in the city of Imabari, in Ehime Prefecture. Its shape and color scheme was carefully considered because it is inside the bounds of the Inland Sea National Park. It can also be viewed as a copy of the Nakanoseto Bridge. From the Bridge Park, one can see all the bridges from Osakishimojima Island to Okamurajima Island all at once.

Main Characteristics
Design: Nielsen-Lohse bridge (a type of bridge whose main support structure is an arch)
Length: 228m(Longest span: about 183m)
