Karuizawa Real Estate: Houses and Land in Japan's Mountain Resort Town

Karuizawa sits in Nagano Prefecture, in the mountains north-west of Tokyo, and is known as a cool-summer retreat with a long history as a resort for Tokyo families and foreign residents. The Shinkansen link to Tokyo takes roughly an hour and a quarter, which is why many owners treat it as a weekend or second home and some commute on a part-time basis.

Winters are cold and snowy enough for skiing nearby, so look closely at insulation, heating and whether a house is built for year-round use. Summer-only cottages can be much cheaper to buy and much more expensive to make comfortable.

Japan does not restrict foreign nationals from owning land or buildings, and you do not need to be a resident. The practical hurdles are financing (domestic banks are cautious with non-residents), language, and understanding what you are buying: land and building are valued separately and older wooden buildings are often priced as land only.

• Use a bilingual agent and a judicial scrivener to handle registration.
• Expect acquisition tax, registration tax, stamp duty and annual fixed-asset tax; confirm rates with a local adviser.
• Check access: private roads, water supply and septic systems are common in mountain areas.

Karuizawa is one of several areas worth comparing. Nagano is the prefectural city, Hakuba is a separate ski-led market elsewhere in the same prefecture, and Tokyo offers a very different, urban price profile. For a wider view see Japan market data.
