Sanmachi-suji — Ichi-no-machi, Ni-no-machi and San-no-machi — are three parallel streets at the heart of Takayama's old town, lined with dark wooden merchant houses from the 17th and 18th centuries. The wide eaves, low-slung windows and lanterns make this one of the best-preserved Edo-period townscapes in Japan.
The street is lined with sake breweries (look for the cedar balls — sugitama — hanging outside each), miso shops, craft galleries, and small cafes. It is busy with tour groups by mid-morning; arrive early or in the evening when the lanterns are lit and most visitors have left.
