Travel notes for Karuizawa Machi

From Wikivoyage

Karuizawa (軽井沢) is a town in Nagano prefecture, famous as an upscale summer resort.

Understand+

Karuizawa, at about 1000m above sea-level, is a famous mountain resort in eastern Nagano Prefecture. Elegant summer houses are scattered through the nearby forests, while the central part of the town is elegantly laid out with restaurants, cafes and boutiques.

History:

In the late 1800s, Canadian missionary Alexander Croft Shaw said that Karuizawa was a wonderful summer resort. Since then, foreigners have been flocking to Karuizawa. It was remarkable for its unspoilt nature, and climate that was several degrees cooler than Tokyo in the summer (and still is!). As such, there are a number of Christian churches, which is very unusual for a small Japanese town. You can also see a variety of western-style buildings dotted around.

Climate:

The climate in Karuizawa is known for being remarkably cool, and generally is about 5°C cooler than Tokyo in the summer. It also often gets quite misty.

Tourist information:

The local tourist association has two official multilingual guide sites, one here, and one here. It's unclear why there are two of them. The more, the merrier? There's also an official pamphlet.

Dog tourism: Amusingly, Karuizawa promotes itself as a "dog tourism" location and has an official website full of dog-friendly locations and activities. The website is only in Japanese, but if you're passionate enough about spending time with your dog, surely you can figure it out (alternatively, you can just look at the gallery of cute dog pictures).
