Hot white steam and a faint rusty mineral scent immediately drift through the air, making you feel like you’ve stepped into an old-fashioned Japanese movie! Ranked as one of Japan’s Three Ancient Hot Springs, its history goes back so far that even ancient emperors, nobles, and the great Sengoku-era ruler Toyotomi Hideyoshi couldn’t get enough of it, coming here from time to time to soak and recover. The entire hot spring town is built along the mountainside. As you slowly climb the winding, hilly stone-paved path called Yumotozaka, you’ll see old-fashioned wooden machiya townhouses, teahouses, and souvenir shops made of dark wood lining both sides. With the crisp clacking of wooden geta, even just wandering around feels incredibly relaxing and restorative.
The most exciting highlight of Arima is definitely its two magical hot springs with completely opposite qualities—Kinsen and Ginsen! Kinsen is originally clear when it emerges, but because the water contains extremely high concentrations of iron ions and salt, it oxidizes upon contact with the air and turns a rich reddish brown. It looks just like a pool of warm, creamy milk tea. It retains heat extremely well, warming your entire body and really driving away the cold. Even the free public footbath by the entrance is always filled with travelers relaxing and soaking their feet. Ginsen, on the other hand, is a clear and transparent carbonated and radioactive spring. After soaking, your skin feels silky smooth, and the circulation throughout your body feels better. Two kinds of enjoyment, all in one visit!
Besides soaking until every pore in your body feels refreshed, the local street food around the hot spring town is impossible to resist! Freshly made, steaming onsen manju are soft, fragrant, and sweet when you bite into them. The thin, crisp traditional tansan senbei have a light sweetness, and you can also grab a cold, refreshing bottle of local Arima carbonated soda along the way. The moment the refreshing bubbles burst on your tongue, they perfectly balance the lingering warmth from the hot spring.
