©ほじん- Fotolia

Onsen (hot springs) in Japan needs no introduction – soaking in piping hot waters is such a warm balm for the soul, be it recharging oneself after a long day of travelling or escaping from a cold winter day. To be recognized as an onsen, the waters must contain at least one of 19 useful minerals such as aluminium and iron, so you can rest assured that spending time in the onsen will reap you substantial health benefits. Now, with about 28, 000 hot springs all over the country available for use, the question arises as to which onsen will yield you the most pleasure for your time and money. From Hokkaido to Okinawa, this article profiles ten of the best-known and best-hidden onsen in Japan, so head on down to them to create your own priceless onsen memories!

Derived from the Ainu word “Nupurupetsu” (dark, cloudy river), Noboribetsu Onsen is arguably the most famous onsen in Hokkaido which lives up to its name by spewing 10, 000 tons of muddy water every day from the nearby Jigokudani Valley. Don’t underestimate these muddy waters as they actually contain nine types of waters, a mind-boggling range that includes salt/saline spring, sulphur spring, radium spring, among others! As you immerse yourself in such mineral-rich waters, you can also feast your eyes on the verdant greenery of Shikotsu-Toya National Park.

Mention Kumamoto Prefecture, and its irresistibly cute mascot, Kumamon springs to mind. However, do you know that Kumamoto is also home to Kurokawa Onsen, a cluster of 30 onsen that are located along the Tanoharu River? Here, instead of gazing longingly at faraway mountain or ocean views, you can gain a cozy experience as you take a dip in hot springs located just beside romantically trickling streams and lush greenery. What better way to get up close with Mother Nature? Also, Kurokawa Onsen scores points for letting visitors buy a cedar pass for 1300 yen that gains them entry to three onsen of their choice. Thus, die-hard onsen lovers can enjoy three distinct experiences in one day. How freaking cool is that?

Tsuboyu Onsen

Tsuboyu Onsen may appear to be an insignificant place at first, for it is just a small stone bath in an equally small cabin set atop Yunotani River in Wakayama Prefecture. However, its reputation packs a powerful punch as it is a World Heritage-listed site! Linked closely to the Kumano pilgrimage, it bore witness to how pilgrims far and wide braved long journeys to get a respite from the healing waters – a fine example that we ought to emulate. Only 2 people can use the bath at any one time, so it is recommended that you come early in the day so that you can wait successfully for your turn. When your turn has come, be sure to stay in the waters for the whole of the 30 minutes allocated to you so that you can get a thrill if the water of Tsuboyu Onsen changes color. (It is said to change color a whooping seven times a day!)

-English Name: Tsuboyu Onsen
