This article comprehensively explains the charm of Gomaya Shiki Water, detailed access methods, water quality information, historical background, and nearby tourist attractions—information you should know before your visit.
What is Gomaya Shiki Water?
Gomaya Shiki Water is a natural spring water spot located in the Terayama district of Hadano City. This spring water, nurtured by the abundant nature of the Tanzawa mountain range, has become a popular water collection spot visited not only by local residents but also by many people from the Keihin area due to its refreshing quality and delicious taste.
Origin of the Name and History
The name “Gomaya Shiki” has deep historical roots. Gomaya Shiki refers to a place where mountain priests performed religious training by burning wood from Toxicodendron vernicifluum and other trees. It is said that in the past, monks and mountain priests who visited here for training purified themselves with the clear spring water from this location.
This legend became the origin of the name “Gomaya Shiki Water,” and it has been treasured as water deeply connected with faith since ancient times. From an era when mountain worship was prevalent, the water at this location was recognized as a special presence.
The Relationship Between Hadano City and Spring Water
Hadano City is the only basin in Kanagawa Prefecture, and its underground structure serves as a natural water reservoir. Rain and melted snow from the Tanzawa mountains seep into the ground and accumulate approximately 750 million tons of groundwater.
This abundant groundwater springs up at various locations throughout the city, forming numerous spring water spots known as the “Hadano Basin Spring Water Group.” The city’s water quality is nationally recognized, having once ranked first in the deliciousness category of the Ministry of the Environment’s Top 100 Famous Waters.

Detailed Access Methods
