Visiting Kanayama Megaliths in Hida-Kanayama


Hello Fans of Kanayama Megaliths:

We have been communicating with you about Iwaya-Iwakage and the megaliths of the Kanayama Megaliths System for nearly two years, since June 2015. During this time, we have explained the intricacies of the observational methods employed here, and have presented our super-accurate solar calendar. We have shared our photos of the solar light phenomena at the three sites at different times of the year. Especially exciting to us was our trek up the Higashinoyama to view the winter solstice sunrise. And we recently posted the oval spotlight in Iwaya-Iwakage on spring equinox day.

Iwaya Valley Three Sites

The three sites of Kanayama Megaliths in Iwaya Valley. As you know, the system consists of three groupings, at three sites, near the Iwaya Dam. The Kanayama Megaliths complex is so fascinating and rich with things to discover that you may want to spend more than a day visiting us. This is a lovely forested area in the mountains of Hida with fresh air and clear streams — and waterfalls! Increasing numbers of visitors have been coming to the Megaliths, to the quaint town of Kanayama, and to this blogsite. So we thought we’d provide updated information about visiting us. This Google map shows the forested region around Kanayama.  Sometimes, the town is called Hida-Kanayama, Kanayama in Hida, or Hidakanayama

  • Where are the Kanayama Megaliths located?

Gero City.  The Kanayama Megaliths are located in the mountains of Hida, in Kanayama Town, city of Gero. The city of Gero is in the middle of Gifu Prefecture. The lower arrow in this map of Gero-shi points to Kanayama, the upper arrow to the Megaliths. The Kanayama Megaliths website gives location information here

Gifu Prefecture and Hida.  In the map at the top of this page, Gifu Prefecture is the green area. As you can see, Gifu Prefecture lies to the north of the city of Nagoya, the third largest city in Japan and the capitol of Aichi Prefecture. The part of Gifu Prefecture from Hidakanayama north to the top of the map is traditionally called Hida, an ancient and somewhat mysterious place. The towns of Hida-Takayama and Shirakawa-go are well known internationally.

Chubu.  Gifu is a prefecture in the region called Chubu. Although you may not be familiar with the name Chubu, it means literally, “central part,” and it refers to the central region of the main Japanese island of Honshu, namely Central Japan. It is officially made up of nine prefectures. Gifu Prefecture is shown left of center in this Wikimedia Chubu map in lime green. The Hida mountains, the “Northern Japanese Alps,” separate Gifu from Nagano Prefecture to its east.

  • How do I get to Hida Kanayama in Chubu?

By Air.  Please refer to the above Kanayama Megaliths link for detailed information on getting to Kanayama by air from Osaka and Tokyo. The closest airport has the code name NGO. In Japan, it is called Centrair or Chubu and is actually located in Tokoname city. To Westerners, we know it as Nagoya Airport. The Kansai International Airport, KIX, is in Osaka. The Narita International Airport, NRT, and Haneda International Airport, HND, serve Tokyo. Whether by air or by train, we suggest that you make your way to Nagoya Station in the city of Nagoya, Aichi Prefecture.


Access map.  The access map at the top of this page shows the routes from Nagoya and from Takayama 高山 to Hidakanayama and the Kanayama Megaliths by train and by highway.

By train.  We suggest you come by way of Nagoya Station. There, you catch the Hida Wide-View express train on the Takayama line that is headed north to Takayama. It will take you to Hidakanayama station in a mere 90 minutes. There are only a few Wide-Views per day, so plan accordingly. The train route (bold dashed line) goes from Nagoya north to Kanayama and beyond. You can see that it parallels Route 41. The route and timetable website,, is very useful. Be sure to enter the  name of the station as HIDAKANAYAMA. Look for the routes of the Hida Wide-View. It’s a good idea to stick to express trains, direct routes, and major cities.

By car.  To drive to Kanayama from Nagoya, take Route 41 north-north-east. It will take you right into town. Driving time is about 1 hour 45 minutes.

  • How do I get to Kanayama Megaliths from Kanayama Town?

The Kanayama Megaliths are, of course, not in town but rather in the mountains. You can get to the megaliths from town in about half an hour by car. A taxi is available for hire, with a special fare for megalith visitors. Head north from town, taking the left fork, Route 256. You will be headed for Iwaya Dam. When you come to the fork, take the right on to Route 86. Stay on Route 86 as it curves around. As you come down the bend into Iwaya Valley, slow down since the entrance to the megaliths will be on your left, a hard left. 

VISIT KANAYAMA.002 LWhen driving from Nagoya directly to Kanayama Megaliths, you have two choices:

  1. Nagoya —(国道 Route 41号)—Kanayama— (国道 Route 256号)—(県道 Route 86号)—Kanayama Megaliths
  1. Nagoya —(国道 Route 41号)—Kanayama— (国道 Route 41号)—(ささゆりトンネル Sasayuri Tunnel)—Kanayama Megaliths

They take about the same amount of time. When taking the Sasayuri Tunnel, be sure to take the immediate left after exiting the tunnel.

When you use a mapping website or app, you might want to enter as your destination “Myoken Shrine.” That is the name of the small shrine on the site of the megaliths. Entering “Myoken Shrine” on Google Maps will give you this close-up view of the last bend.
