This is Isumi Shrine ⛩️ in Otaki Town. I deliberately included the old building called "Ooya" next to the torii gate ⛩ in the photo. This is the Ooya Ryokan, a temple inn that has been operating since the Edo period. It's an inn with an atmosphere that makes you feel like a zashiki-warashi (house spirit) might appear 💦
Now, let's proceed along the approach to the shrine.
According to the Isumi Shrine website:
"Isumi Shrine was founded in 1590 when Honda Tadakatsu became the lord of Otaki Castle and, in developing the castle town, moved the Jinguji temple, which was located at the current site, to Kuriyama, and invited Gozu Tenno (a deity) from Gion-in Daienji Temple, enshrining the Gozu Tenno Shrine."
Gozu Tenno is a deity that combines the guardian deity of Jetavana Monastery in India with the Yin-Yang philosophy of China. In Japan, he is considered a deity further syncretized with Susanoo-no-Mikoto, and is the enshrined deity of Gion Yasaka Shrine in Kyoto.
Isumi Shrine was renamed from Gozu Tenno Shrine to Isumi Shrine following the separation of Shinto and Buddhism during the Meiji era, and its enshrined deity was said to be Susanoo-no-Mikoto.
During the recent renovation of the shrine's roof, an investigation was conducted inside the main hall to relocate the sacred object to a temporary shrine. A mirror wrapped in brocade cloth was discovered inside the pedestal of the sacred object.
The mirror is inscribed with "Susanoo-no-Mikoto" in the center, "Ōnamuchi-no-Mikoto" on the right, and "Inada-hime-no-Mikoto" on the left, revealing that the enshrined deities are three gods.
There is an old-fashioned waterway within the grounds of Isumi Shrine.
The information board states that it collects rainwater from the Shinchō-Kamijuku area, creating a landscape that harmonizes with the shrine's grove, shrine buildings, and drum bridge.
It also mentions the presence of carp and crucian carp, but I was unable to confirm this. The worship hall is magnificent and dignified. As expected of a shrine that stands as the guardian shrine of Ōtaki, a castle town known as the "Little Edo of Bōsō."
The information board next to the worship hall states that the shrine is built in the Gongen-zukuri style, consisting of a worship hall, offering hall, and main sanctuary.
The carvings are also wonderful. The divine virtues of the three enshrined deities include a wide range of blessings such as abundant harvests, protection of agriculture and fishing, safety at sea and in traffic, academic success, business prosperity, family safety, protection from evil and good fortune, recovery from illness, as well as matchmaking, marital harmony, safe childbirth and child-rearing, national security, and peace and stability.

Located on Otaki Castle Town Street, this shrine serves as the local guardian deity. It's also known for its morning market.
While the founding date is unknown, it was rebuilt in the mid-Heian period and is said to have been renovated during the Sengoku period under Masaki Daizennosuke Tokitaka, making it one of the most prestigious shrines in Otaki. The enshrined deity is Susanoo-no-Mikoto.
The existing shrine buildings were constructed in stages during the Edo period, consisting of the main hall, regular hall, and worship hall, and the current structure continues that tradition.
Visit the shrine to see the sculptures.
While the artist is unknown, both the worship hall and main hall are filled with sculptures, making for a truly impressive composition. The ceiling painting on the porch has faded, making it difficult to discern the detailed design.
It is our hope that these sculptures will continue to be carefully preserved as cultural assets of the shrine that have been passed down along with the history of the castle town.

I stopped by on my way back from surfing.
Apparently, you can only get the temple stamp on January 1st and 2nd, and it's very quiet on weekdays when there's nothing special going on.
There's not much else around, except maybe Otaki Castle, which is a little further away.
(Memo)
- Visited the shrine a little after 9 AM on Saturday.
- There is ample parking space behind the shrine.
- I walked around the well-maintained grounds, admiring the carvings.
- There are no goshuin (shrine stamps), but it's a shrine that I felt was worth the trip, even from far away.
