Hakone Onsen — relief & relaxation | Compare & book 13 inns

Overview

Hakone Onsen, located in southwestern Kanagawa Prefecture, is a premier hot spring destination in Japan. Its history dates back to the Nara period (710-794) when the first spring was reportedly discovered. During the Edo period, it flourished as a post town on the Tokaido highway, offering rest to weary travelers.

Since the Meiji era, it has evolved into a resort destination favored by both Japanese and international visitors. Today, the area is a collection of 17 distinct onsen towns, including Yumoto, Tonosawa, Gora, and Sengokuhara, collectively known as the "17 Springs of Hakone" or "20 Springs of Hakone." The main appeal lies in the diverse water types and atmospheres each area offers.

Major Spring Types and Benefits

Hakone is often called a "department store of hot springs" for its rich variety. The simple thermal springs are gentle and suitable for everyone, believed to promote deep relaxation. Chloride springs provide excellent restorative warmth. Sulfur springs, sourced from areas like Owakudani, are known for their characteristic scent and milky-white water, which is said to help achieve silky skin.

Water Characteristics and Best Season to Visit

A wide variety of hot springs gush forth throughout the Hakone mountains, with an abundant supply of water. While facilities vary between using free-flowing spring water (gensen-kakenagashi) and circulated systems, high-quality baths are widely available at hotels and day-use onsen. Spring temperatures typically range from 40°C to 60°C and are adjusted to a comfortable bathing temperature.

Hakone's beautiful seasonal landscapes make it a year-round destination.
