北杜市と小淵沢町
「八ヶ岳」とは、特定の山の名前ではなく、山梨県（山梨県）と長野県（長野県）の両県にまたがる山の総称です。
八ヶ岳は、北の蓼科山（標高2,530m）から編笠山（標高2,524m）まで、南北約25kmに及ぶ約20の山々からなる火山列です。火山の噴火は周囲の南北60キロメートル、東西25キロメートルの範囲で見られます。最高峰は赤岳（標高2,899m）です。南北に長い八ヶ岳は、夏沢峠を境に北八ヶ岳と南八ヶ岳に分かれ、山容が異なります。
世界百名山とも呼ばれる八ヶ岳は、日本の有名な山々は、山頂が浸食によって削られた一連の峰と、その麓を囲む巨大な扇状地で構成されています。その地域の大部分は八ヶ岳中信高原国立公園に指定されています。この地域は火山性のため、温泉が数多くあります。山麓には地下水が流れているため、特に町の南西部には縄文時代の遺跡が多く残っています
小淵沢町は長野県との県境に位置し、八ヶ岳高原の山梨側への玄関口として知られています。 2006年3月15日、隣接する北杜市と大合併し、現在は北杜市小淵沢町として市の行政区の一つとなっている。小淵沢は甲信越道沿いに位置している。甲信越国境、甲府盆地と諏訪盆地のほぼ中間に位置し、古くから交通の要衝でした。
この町は古くから交通の要衝とみなされており、この立場は今も変わらない。近代的な交通システムが発達した現在でも、町内には中央本線と小海線の2つの鉄道路線が通っており、中央自動車道のインターチェンジもあります。さらに、小淵沢駅は中央線の特急停車駅でもあるので、乗り換えなしで首都圏（新宿駅）から簡単にアクセスできます。
町の形は左手で銃を撃つポーズ（人差し指と親指を伸ばし、残りの指を握る）に似ており、伸ばした指が旧小淵沢町、握った指が旧篠町の地名で、人差し指の先が編笠山と権現岳にあたります。
「八ヶ岳南麓の町」で、八ヶ岳連峰を北に望む斜面は山頂から南に向かって緩やかな傾斜で、町のほぼ全域が3度以上の傾斜地となっている。町の大部分は七里岩と呼ばれる台地に位置し、釜無山は釜石の斜面と重なる。七里岩台地の下を流れる釜無川も町域に含まれています。
町の境界は台地の下を流れる釜無川である。七里岩は釜無川の手前の急峻な崖で、町内の最高地点から最低地点までの標高差は約2,100メートル。町の西端には甲六川が流れ、富士見町との県境を形成しています。
"Yatsugatake is not the name of a specific peak, but a general term for mountains that cover both Yamanashi and Nagano prefectures.
Yatsugatake is a volcanic chain of about 20 peaks stretching about 25 km from north to south, from Mt. Tateshina (2,530 m above sea level) in the north to Mt. Amigasa (2,524 m above sea level) in the south.
The volcanic eruptions can be seen in the surrounding area of 60 km from north to south and 25 km from east to west. The highest peak is Mt. Akadake (2,899m above sea level).
Yatsugatake, which is long from north to south, is divided into North-Yatsugatake and South-Yatsugatake with the Natsuzawa Pass as a boundary, showing different mountain shapes.
The Yatsugatake mountains, which are referred to as the 100 most famous mountains in Japan, are composed of a series of peaks cut by erosion at their summits and surrounded by a huge alluvial fan at their foot. Most of the area has been classified as Yatsugatake Chushin Highland National Park. Because of the volcanic nature of the area, there are many hot springs in the area.
Because of the subterranean water flowing at the foot of the mountains, there are many remains of the Jomon period, especially in the southwestern part of the town.
Hokuto City and Kobuchisawa
Kobuchisawa is located on the border with Nagano Prefecture and is known as the gateway to the Yamanashi side of the Yatsugatake Highlands. On March 15, 2006, the city was merged into the neighboring Hokuto City in a major merger and is now known as the Kobuchsawa-cho district of Hokuto City, one of the city's administrative districts.Kobuchisawa is located on the Koshin border, roughly halfway between the Kofu and Suwa basins, and has been a major transportation hub since ancient times.
The town has been considered a major transportation hub since ancient times, and this position is still true today, even with the development of modern transportation systems, with two railroad lines running through the town, the Chuo Main Line and the Koumi Line, and an interchange on the Chuo Expressway. Furthermore, Kobuchisawa Station is also a limited express stop on the Chuo Line, making it easily accessible from the Tokyo metropolitan area without changing trains.
It is a "town at the southern foot of Mt. Yatsugatake," with the Yatsugatake mountain range to the north at the top and a gentle slope toward the south, and almost the entire town has a slope of more than 3 degrees. Most of the town is located on a plateau called Shichiriwa, and the Kamanashi River that flows under the Shichiriwa plateau is included in the town area.
The town is bordered by the Kamanashi River, which flows under the plateau. Shichiriwa is a steep cliff in front of the Kamanashi River, and the difference in elevation from the highest point to the lowest point in the town is about 2,100 meters. The Kouroku River runs along the western edge of the town, forming the prefectural border with Fujimi Town.
The shape of the town is similar to that of a pose of firing a gun with the left hand (index finger and thumb extended and the remaining fingers grasped), with the extended fingers corresponding to the former Kobuchisawa-cho, the grasped fingers corresponding to the former Shino―cho, and the tip of the index finger corresponding to Mt Amigasa and Mt. Gongen.
Kobuchisawa-cho
The Kobuchisawa plateau is located at an elevation of around 1,000 meters, surrounded by rich nature, with a view of the magnificent Southern Alps and Mt. Fuji can be seen in front of the plateau. Even in summer, the area is cool with low humidity, and has long been suitable for raising horses. Today, there are many horse riding clubs, mainly for the Yamanashi Prefecture Equestrian Games, and the area is also known as a "horse town". In winter, the contrast between the blue sky and the snow-covered mountains, known as Yatsugatake Blue, is spectacular. At night, the air is crisp and clear, and the sky is filled with stars. Kobuchisawa is full of places that make you want to take a detour, such as the Shingen Stick Road(信玄棒道), which is said to have been built by Takeda Shingen(武田信玄) as a military road, limpid spring water refined by the peaks of the Yatsugatake Mountains, an art museum nestled in the forest, an outdoor skating rink with a circumference of 400 meters, the Enmei no Yu(延命の湯) (hot spring) containing highly concentrated minerals, and delicious highland vegetables.
