The Honden (Main Hall) is a sacred building dedicated to the shrine’s deity. Its construction was completed in 1924 (Taisho 13 in the imperial calendar). The main hall is built in the “Nagare-zukuri” architectural style. Its large scale and horizontal length are known as “Sangensha Nagare-zukuri”. The roof protrudes forward in the front with a long, curved shape to create a kohai (eave-covered space for worshippers).
It is also thatched with flame-resistant and durable copper plates.
The use of traditional designs such as the geometric patterns on the kibana protruding from the tops of the pillars and the arabesque patterns on the kaerumata (curved wooden struts) beneath the eaves create a refined atmosphere.

The Haiden (Worship Hall) is the building where visitors go to pay their respects to the deity of the shrine.
Aoba Shrine’s Haiden was built in 1927 (Showa 2 in the imperial calendar), located at the end of the approach to the shrine, is the core building within the shrine complex. It features a copper-plate-thatched "Irimoya-zukuri" hip-and-gable roof and a kohai in the front. A kohai is a protrusion of the roof (eave) that creates a space for worshippers.
Inside is a single tatami-mat room, with an elegant coffered ceiling made with long strips of wood arranged in a lattice pattern. This is made by assembling thin square pieces of wood into a grid, without using nails, and then laying planks across the top.
The verandas also have balustrades on all four sides.

The Chumon (Middle Gate) in front of the main hall and the Noritosha (Prayer Hall) behind it were built in 1927 (Showa 2 in the imperial calendar), after the construction of the main hall.
　In addition to the two central pillars, the Chumon Gate has four support pillars, two in the front and two in the back, which is known as a “Shikyakumon” gate design. The roof has the appearance of an open book laid face down, creating a mountain-like shape, a style called “Kirizuma-zukuri”. The roof is covered with thin overlapping sheets of copper.
　The Noritosha is where norito, prayers that are to be chanted to the deities, are read aloud by priests. Its roof is the same as that of the Chumon, a thatched copper-plate roof with a gabled Kirizuma-zukuri design. It is an open space with no walls known as a “Fukihanachi”.

The Sukibei Wall surrounds the main hall, where the deity is enshrined, and serves to separate it from the earthly world. Its name comes from the fact that one can look through it to see the area inside. Only a limited number of people are allowed within its confines, while others outside can see what is going on inside.
This wall, built in 1927 (Showa 2 in the imperial calendar), has narrow rectangular openings that form lattice windows through which the main building can be faintly seen. The roof is thatched with plates made of copper, a metal known for its light weight and durability.
Brick is used for the foundation, giving it appearance that captures the feeling of the era when it was built.
While the design is simple, the materials and technology used are of high quality.

The Shinsenjo (Building for the Preparation of Divine Food) is the building adjoining the worship hall, where sacred meals offered to deities are prepared. There is also a corridor that connects the Shinsenjo to the worship hall that is used to carry these offerings. This corridor is called the Denkuro. Construction on both was completed in 1929 (Showa 4 in the imperial calendar).
The Shinsenjo is made with an "Irimoya-zukuri" hip-and-gable roof. It is thatched with durable copper plates.
　The Denkuro’s roof is a thatched copper-plate roof with a gabled Kirizuma-zukuri design. The floor is made of wooden planks, and the lack of a ceiling affords a view of the beautifully arranged attic.

The Former Sayado of Megohime Shrine is a structure that was built to cover the Honden (main hall) of the shrine dedicated to Megohime, wife of Date Masamune (1567-1636), first lord of the Sendai Domain, and protect it from the wind and rain. When it was completed in 1931 (Showa 6 in the imperial calendar), it was located to the southeast of the Haiden (worship hall). In 1945 (Showa 20), after the end of World War II, Megohime Shrine’s Honden was moved into Aoba Shrine’s main hall and the Sayado was moved to its current location out of fear that the shrine might be destroyed. Since its relocation it has been used as a space for selling amulets.
　The Sayado has an "Irimoya-zukuri" hip-and-gable roof thatched with copper plates. Inside is a tatami-mat room with a coffered ceiling made with long strips of wood arranged in a lattice pattern. It is a small structure that is not ornately decorated, but the curves of its eaves are quite beautiful.
Since becoming an amulet shop, the building’s front has shifted 90 degrees; the side with the panelled wooden door or sankarado was the front when it was still in use as the Sayado.
