The Shorter of Two Registered Platforms
The Tobu Railway Daiyamuko Station Inbound Platform (東武鉄道大谷向駅上りプラットホーム) is a cobble-faced earth-fill railway platform of 1931 in Daiyamuko Station in Imaichi, Nikko City, Tochigi Prefecture, and was registered as a Registered Tangible Cultural Property (structure) on October 27, 2017 (Agency for Cultural Affairs).
The Agency records a stone structure 61 metres long, altered between 1960 and 1964; registration number 09-239.
The Pair to the Outbound Platform
The Tobu Railway Daiyamuko Station Inbound Platform was built together with the outbound platform when Daiyamuko Station was moved to its present site (Agency for Cultural Affairs). It lies south of the outbound platform and is 61 metres long, 6 metres shorter than its pair.
It uses the same tamaishi-zumi earth-fill method, with rounded cobbles thought to come from the Kinugawa and Daiya river basins (Agency for Cultural Affairs). The 2 platforms of the one station are registered as separate properties.

Why It Was Registered
The Tobu Railway Daiyamuko Station Inbound Platform was registered under the criterion of contributing to the historic landscape of the country. As with the outbound platform, the Agency sees it as a record of the modernisation of the Kinugawa Line.
What to Look For
From the Tobu Railway Daiyamuko Station Inbound Platform the stone face of the outbound platform can be seen across the track, and this platform's own stonework is in turn viewed from the other side. Compare the two to see the same way of laying the cobbles.
The platform was altered between 1960 and 1964, but the Agency's description does not say which parts were changed.
