Japan Vertical Datum

Japan Vertical Datum Hakkında

The Japan Vertical Datum, known locally as 水準原点 (Suijun Genten), is a geodetic benchmark serving as Japan's official reference point for measuring elevation above sea level. Established for surveying and cartographic purposes, this scientific monument provides the foundational zero-height standard used in topographic maps, construction projects, and engineering works throughout Japan. The monument represents a critical piece of national infrastructure for spatial measurement, though it is not designed as a conventional tourist attraction. Visitors should understand this is primarily a technical reference point with limited public interpretation facilities.

Oraya varmak

The Japan Vertical Datum is located in Tokyo's Kasumigaseki district, an area well-served by public transportation. Multiple Tokyo Metro stations provide nearby access, including Kasumigaseki Station serving the Marunouchi, Hibiya, and Chiyoda lines. The monument sits within walking distance of these underground stations. Street-level navigation requires attention to specific address location rather than prominent signage. The surrounding government district features regular street patterns but limited distinctive landmarks for orientation. Mobile mapping applications using the OpenStreetMap node reference prove valuable for precise location. Walking from nearby stations involves standard urban distances through commercial and administrative streetscapes.

Nelere dikkat edilmeli

Visitors should recognize this is a functioning scientific instrument within an active administrative district, not a recreational facility. Photography is possible from public spaces but should avoid interfering with any maintenance or monitoring activities. The Kasumigaseki area contains numerous government buildings; visitors should remain on public thoroughfares and respect any restricted zones. No visitor services such as restrooms, seating, or refreshments are available at the monument itself. Weather exposure requires appropriate preparation.
