“Hoshino Community Base” enriches Karuizawa life
At Hoshino Community Base, we hold courses, workshops, and events with the theme of "enriching life in Karuizawa" for people living in Karuizawa and its surrounding areas.

Hoshino Community Base aims to become a place where participants can gain knowledge and information that will enrich their lives in Karuizawa, get active in nature, and before they know it, the number of familiar faces is increasing. That's what I'm aiming for.
``Base'' is located at the base of Mt.Asama and expresses our desire to be a base where loose connections and communication are born between people who love living in Karuizawa. I put it in.
There is no registration process or membership fee required. If there are any courses or events that interest you, you can participate individually.

Whether you're a beginner or a veteran, you can all spend time working on your hands in a heartwarming atmosphere.

Learn from a gardener how to enjoy Karuizawa's gardens [March and April]

One of the joys of living in Karuizawa is appreciating the growth and changes of the plants in your garden every day. We held a gardening seminar for people who don't know where to start with gardening, people who haven't yet made the most of their garden, and people who want to make their garden better.

KIDS solo hot spring debut【January March】

This is a hot spring course to support children so that they can go to a hot spring by themselves when they enter elementary school. In recent years, the age at which children can bathe together has been lowered nationwide. At Hoshino Onsen Tombo-no-Yu, girls are no longer allowed to enter the men's bath and boys are no longer allowed to enter the women's bath once they reach elementary school. In this course, you will learn bathing etiquette through classroom lectures, and then take a bath under the supervision of staff.

Start with the staff from Hoshino Onsen Tombo no Yu in Karuizawa and run along the mountain stream. Feel the fresh breeze of the new greenery as you go, slowly and without straining yourself.

Coffee Course: Learn the Differences in Taste - Advanced Level [May]

This class was taught by Maruyama Coffee staff on the terrace of Maruyama Coffee, where you can feel the nature and learn about the depth of coffee. We conveyed the depth of coffee by comparing the changes in taste caused by the storage conditions of the beans and the equipment, and the differences in characteristics depending on the country of origin and refining method.
