[Touring Spot] [Nagano Prefecture] Bike trip to Bunkui Pass! A solo trip on a Harley to Japan’s largest fault and power spots

Hello, this is _hiroyuki.ta. This time, I toured from central Tokyo to Bunkui Pass in Nagano Prefecture on my Harley-Davidson FLSB Sport Glide. Bunkui Pass is located directly above the Median Tectonic Line, the largest fault in Japan, and is famous as a natural power spot. We will introduce its charm and route.

What is Bunkui Pass?

Bunkui Pass is a mountain pass with an altitude of 1,424m located on the border between Ina City, Nagano Prefecture and Oshika Village, Shimoina District. This is one of the passes on the Akiba Highway (currently National Route 152), which has been used for a long time as a road to Akiba Shrine in Hamamatsu City, Shizuoka Prefecture. Akiba Kaido is a road that utilizes the fault valley of the Median Tectonic Line, which divides the geology of western Japan into inner and outer zones, and Bunkui Pass corresponds to the Yanaka watershed of the Median Tectonic Line. The name is said to come from the fact that the Takato domain erected a stake to mark the border with other territories (the southern part was the Tenryo), and there is a stone monument at the pass that reads, “Follow the Northern Takato Territory.”

Bunkui Pass is geologically fragile because it is a road that uses the fault valley of the Median Tectonic Line, and although the roads near the pass are paved and maintained, they frequently collapse (regardless of their size). , the entire mountain pass section is often closed to traffic. Therefore, you will need to take a shuttle bus to get to the pass.

Bunkui Pass is located directly above the Median Tectonic Line, the largest and longest massive fault zone in Japan, and because two geological layers collide, it is called a zero magnetic field power spot where energy is condensed. I’m doing it³. The first power spot was near the pillar tree at the bottom of the forest road, and later people started to gather at the water hole at the back of the forest road. In 2009, the zero magnetic field at Bunkui Pass was widely covered on TV, radio, and magazines, and the number of tourists visiting Bunkui Pass increased rapidly. Naturally, these ideas lack scientific basis and are considered a form of pseudoscience. Kazuo Kawamoto, a curator at the Median Tectonic Line Museum, points out, When no earthquake occurs, a fault is mechanically the same as the surrounding rock,'' adding,The theory that “rock is pushed together due to a fault” The idea is geophysically incorrect.”

Route to Bunkui Pass

The route to Bunkui Pass takes approximately four and a half hours from central Tokyo via the Shuto Expressway Inner Loop Line, Shuto Expressway No. 4 Shinjuku Line, Chuo Expressway, National Route 20, and National Route 152. On the way, exit the Chuo Expressway at Suwa IC and pass through the Suwa Bypass. This bypass is known as the birthplace of Shinshu soba, and there are many soba shops along the road.

Once you enter National Route 152, the road becomes a mountain road. Please note that this road may be closed depending on the time of day or day of the week. I passed by on a Sunday morning, and there were still some narrow spots where I could barely pass an oncoming car. However, the scenery was spectacular, and I was able to see mountains, valleys, forests, and other rich natural scenery. In particular, as I approached Bunkui Pass, the fault valley of the Median Tectonic Line came into view, and I was overwhelmed by its power.

Highlights of Bunkui Pass

When you arrive at Bunkui Pass, the first thing you’ll see is a stone monument that says “Follow the North Takato Territory.” This was built by the Takato domain during the Edo period to mark the border with other territories, and has historical value. Looking north from the pass, you can see the fault valley along the Median Tectonic Line. You can see the valleys that were eroded in a straight line and the topography created by fault activity, and you can feel the history of the earth. If you look south from the pass, you can see the mountains of the Southern Alps and Central Alps, and enjoy the magnificent scenery.

If you go down to the valley on the north side from the shuttle bus stop located a little further down the mountain pass, you will find a place called “Kiba”. This place is famous as a power spot with zero magnetic field and is visited by many people. Although there are no shrines or temples, and there are no objects of worship such as giant trees or megaliths, many people find it soothing to spend a quiet and relaxing time in this place. I sat here for a while, and the air was clear and comfortable. However, there is no scientific basis for this, so this is just my personal opinion.

Bunkui Pass motorcycle parking lot

You must take a shuttle bus to Bunkui Pass. The shuttle bus stop is located at the Awasawa parking lot. There is a parking lot for motorcycles here, so park your motorcycle there and transfer to the shuttle bus. The shuttle bus operates from 9:00 to 16:00 and departs every 30 minutes. The shuttle bus takes approximately 15 minutes. The distance from the Awasawa parking lot to Bunkui Pass is approximately 5 km, but the road is narrow and has many curves, so it is dangerous to go there by motorcycle. We recommend using the shuttle bus.

Summary

This time, I toured from central Tokyo to Bunkui Pass on a Harley-Davidson FLSB Sport Glide. Bunkui Pass is located directly above the Median Tectonic Line, the largest fault in Japan, and is famous as a natural power spot. The view of the fault valley and mountains seen from the pass was spectacular. On the way, we stopped at a soba restaurant along the Suwa Bypass, the birthplace of Shinshu soba, and enjoyed some delicious soba. You will need to use a shuttle bus to get to Bunkui Pass, but there is also a parking lot for motorcycles, so you can go with peace of mind. Bunkui Pass is a historically and geologically interesting place, so be sure to visit it at least once.
