Niekawa-juku

It is located in the present-day city of Shiojiri, Nagano Prefecture, Japan.

Niekawa was originally written as 熱川 (niekawa, "warm river") because there were onsen in the area, which made the river warm.

However, the kanji were eventually changed to the ones used today.

Originally built in the Tenbun period (1532-1555), it was the first of 11 resting spots along the Kisoji (木曽路),[1] which stretched to modern-day Nakatsugawa, Gifu Prefecture.

[1] It became part of the Nakasendō during the Edo period.
