| Shrine name | 97% | Center calligraphy reads 秋葉神社 cleanly. Center red square seal in tensho confirms 秋葉神社. The blue rectangular bottom-right seal reads 「秋葉原語源の社」 ("The shrine that gives Akihabara its name") — uniquely diagnostic of the Taitō-Ward Akiba Jinja (not the Shizuoka head shrine of the Akiba network). |
| Date | 97% | Left column reads 令和六年五月二十日 = 20 May 2024. The 「皐月」 (Satsuki — old name for May) seal at top-right and the kabuto + iris-flag motif at top-center fit the documented Tango no Sekku / May seasonal limited goshuin pattern. |
| Variant identification | 94% | The kabuto (samurai helmet), iris-shaped flag, and 火防 (fire-prevention) green gourd are all documented features of Akiba Jinja's Boys' Day-themed seasonal limited goshuin issued during May. |

Why kabuto + iris flag?
端午の節句 (Tango no Sekku — Boys' Day / Children's Day) falls on 5 May every year — part of Japan's Golden Week. Traditional motifs include:
- 兜 (kabuto) — samurai helmet, a symbol of strong, brave young men. Families with sons traditionally display kabuto in their homes.
- 菖蒲 (shōbu — iris) — irises bloom around early May. The word shōbu is a homophone for 「尚武」 (shōbu — "valuing martial spirit"), so iris became associated with Boys' Day. Families also make shōbu-yu (iris-leaf baths) on this day.
- 鯉幟 (koi-nobori) — koi-fish banners flown outdoors. Not on this goshuin but part of the same tradition.
The gold kabuto with the purple iris banner at the top of this goshuin is therefore a Boys' Day visual motif. The user received the goshuin on 20 May, after Boys' Day itself — many shrines extend Tango-themed goshuin throughout the month of May, which is what Akiba Jinja appears to do. (The shrine is documented to issue 「皐月」 (Satsuki — May) goshuin throughout the entire month of May 1–31, with Boys' Day-themed iconography and an option to write "端午" instead of the date specifically on 5 May.)
Why the green gourd with 「火防」 (fire prevention)?
The gourd (瓢箪 / hyōtan) is traditionally considered to have the power to extinguish fire. The Japanese reading hisago / hyōtan contains a folk-etymology link to hi-sago (火-去 / "fire-removing"). Vessels for water are gourd-shaped because gourds were historically used to carry water — a practical tool against fire.
Akiba Jinja is specifically a fire-prevention shrine founded by imperial order of Emperor Meiji in 1870 after a devastating fire in 1869 destroyed much of central Tokyo. The shrine was originally called 鎮火社 (Chinkasha — "Fire-Quelling Shrine"). Its core blessing is 東京火災鎮護 (Tokyo Kasai Chingo) — "Tokyo Fire-Protection".
The green gourd with 「火防」 (Hibuse — fire prevention) stamped on it is therefore the shrine's signature motif, reinforced on this seasonal goshuin alongside the Tango motifs.
About the shrine
Historical origin
In December 1869 (Meiji 2), a major fire (the Negishi fire) destroyed a large portion of central Tokyo. Emperor Meiji personally ordered the establishment of a fire-prevention shrine in 1870 to protect the new capital. The shrine was located in Akihabara (then called 秋葉ヶ原 — "Akiba's Plain") on land that had been cleared as a fire-break.
How Akihabara got its name
The shrine was originally called 鎮火社 (Chinkasha — "Fire-Quelling Shrine"), but locals popularly called it 「秋葉様 (Akiba-sama)」 — assuming it was a branch of the famous Akiba shrines network (秋葉山本宮 in Shizuoka). The misunderstanding stuck, the shrine was officially renamed 秋葉神社 (Akiba Jinja) in 1872, and the area around it became known as 「秋葉原 (Akiba-ga-hara — "Akiba's Plain")」 — eventually shortened to today's Akihabara.
So the entire neighborhood — and by extension Japan's globally-recognized "Akihabara" tech and otaku district — is named after this shrine. The blue stamp 「秋葉原語源の社」 ("the shrine that gives Akihabara its name") on the goshuin makes this etymological connection explicit.
The shrine's relocation
In 1888, the shrine was relocated from its original Akihabara site (now occupied by Akihabara Station) to its current location in Matsugaya, Taitō Ward — about 1.5 km north of Akihabara. Despite the move, the etymological connection to Akihabara remains, and the shrine maintains protector status over the modern district.
Enshrined deities
- 火産霊大神 (Homusubi-no-Ōkami) — fire deity, principal deity
- 水波能売神 (Mizuhanome-no-Kami) — water deity
- 埴山姫神 (Haniyama-hime-no-Kami) — earth deity
The triad of fire-water-earth is deliberate: the water deity counters the fire deity, and the earth deity grounds both.
