Background: Omori Station's 150-Year History

Omori Station first opened on June 12, 1876 (Meiji 9), during the early years of Japan's railway expansion. It was among the stations established on the original Shinbashi–Yokohama line corridor, which laid the foundation for today's extensive Keihin-Tohoku and Negishi Line service. The station sits on the boundary between Ota Ward and Shinagawa Ward, a geographic fact that JR East references in the sourcing of its commemorative wine (see below).

The station has undergone various renovations over the decades and currently serves as a key stop on the Keihin-Tohoku/Negishi Line, connecting riders northward to Saitama (Omiya) and southward to Kanagawa (Ofuna). JR East describes the 150th anniversary as an occasion to express gratitude to riders and the local community.

Event Details: What's Happening and When

The celebration spans the entire month of June, with the main public festival concentrated over three days. Below is a step-by-step breakdown of the key dates, locations, and activities drawn directly from the official announcement.

Starting June 1, 2026 (Monday), a Keihin-Tohoku/Negishi Line trainset will carry a special octagonal headmark featuring the "Omori Station 150th Anniversary Logo." This is noted as the first octagonal headmark in JR East's history.

• Operating section: Keihin-Tohoku/Negishi Line, between Omiya and Ofuna stations.
• Placement: One trainset only (front and rear, one location each).

Step 2: Collect the Limited-Edition "Ekitag" Station Stamp (June 1–30, 2026)

A special commemorative logo version of the "Ekitag" digital station stamp is available at Omori Station for a limited period.

• Location: Omori Station, outside the central ticket gate.
