The Wado Ruins mark the historically significant site where Japan's first official coinage, the Wadōkaichin, was minted in 708 AD. This archaeological area in Chichibu preserves the remains of ancient surface copper mines, providing a tangible link to the origins of Japanese currency and mining history. It's a unique destination for those interested in numismatics, industrial heritage, and the cultural significance of money in East Asia.
Visitors consistently highlight the peaceful, natural setting and the historical importance of the site. The main attractions include the mining remains, marked by a large monument shaped like a Wadōkaichin coin, and the Hijiri Shrine. Reviewers appreciate the opportunity to see where the copper for the first coins was sourced and to learn about the legends associated with the shrine, such as washing coins in the stream for good luck. The shrine itself houses interesting artifacts, including mineral specimens and ancient centipede statues, which are said to protect miners.
To make the most of your visit, allocate about 2-3 hours to explore both the shrine and the mining site. Wear comfortable shoes as there are mountain trails to navigate. While the site is historically rich, some visitors note that the ruins themselves are not extensively preserved, so a keen interest in the subject matter enhances the experience. Consider bringing some coins to wash in the stream at the mining site for the traditional good luck ritual. The best time to visit is during pleasant weather, as much of the exploration is outdoors.
The Wado Ruins are accessible via public transport. Hijiri Shrine is approximately a 5-minute walk from Wado-Kuroya Station. The actual mining site, marked by the Wadōkaichin monument, is about a 15-minute walk further from the shrine along mountain trails. Wado-Kuroya Station is located in Chichibu, which is about a 2 to 3-hour train ride from Tokyo. For those driving, parking options are available near the shrine.
A common complaint is the relatively sparse nature of the ruins themselves, which might not meet expectations for those anticipating grand archaeological structures. To mitigate this, approach the visit with an appreciation for the historical context and the natural environment rather than expecting extensive excavated remains. Reading up on the history of Wadōkaichin coins beforehand can significantly enrich the experience.
