If you are staying in Osaka or Kyoto and want a night in a hot spring town, go to Arima above Kobe, Kinosaki on the Sea of Japan coast, or Ogoto on Lake Biwa. All three are about two hours or less from one of the two cities, all three can be reached by train without a car, and they are the three best-known towns that pass both tests. They are very different trips: one is an hour away with famous water, one is a longer ride to a town built around its public baths, and one is a lakeside hotel stay that barely takes you out of Kyoto. Below is why each one made it, which city it suits, and the towns that only just missed.
We did not pick by taste. Our travel data lists 363 onsen towns within about three hours of Kyoto or Osaka, whichever is closer. Three hours is too far for "near", so among the 240 best known we kept only towns estimated at about two hours or less: 121. We then kept only those you can reach without a car: 97. Three of those, all in Fukushima, carry a time estimate that is plainly wrong, so we set them aside, leaving 94. Finally we ranked the rest by how often each town's Wikipedia article is read, as a measure of how established a town is — the more people look a place up, the more likely it is to have a real town centre, a choice of inns, and baths that take visitors. The top three are Arima, Kinosaki and Ogoto. The full method, with numbers, is at the end.
Our times are measured from whichever of Kyoto Station or Osaka Station is closer, and the three towns do not sit evenly between them. Arima is on the Osaka–Kobe side: 25 km from Osaka Station and 51 km from Kyoto Station. Ogoto is on the Kyoto side, about 17 km from Kyoto Station, and a long way round from Osaka. Kinosaki is far from both, 113 km from Kyoto in a straight line, and the direct trains run from both cities. If your hotel is in Osaka, Arima is the easy one; if it is in Kyoto, Ogoto is.
Why it made it. Arima Onsen is the most looked-up town in the pool: 4,489 in our count, against 3,955 for Kinosaki. Our estimate puts it at about an hour from Osaka.
The town. Arima is a small, old town packed into a steep valley behind Mount Rokkō, which is 2.7 km away. The lanes are narrow and short, and you can cover the whole centre on foot in an afternoon. Tsuzumigataki Park, with its small waterfall, is about a kilometre from the centre.
The water. This is the reason Arima tops most lists. Our records give it four water types — chloride, bicarbonate, iron and radioactive — with sources from 40 up to 98 °C. Locally the water is sold as two kinds: 金泉 (kin-sen), the iron-rich salt water that turns rust-brown in the air, and 銀泉 (gin-sen), the clear one. Many inns have only one of the two, so check which before you book if you want the brown water.
Getting there. From Osaka, direct express buses run from the Hankyū Sanbangai terminal at Umeda. By rail, take the subway from Shin-Kobe to Tanigami and change for the Kobe Electric Railway to 有馬温泉 (Arima-Onsen), a short walk from the centre. The last leg is a private line: the JR Pass does not cover it.
Good for: a base in Osaka or Kobe, a first onsen night that costs you only an hour each way, anyone who wants the most distinctive water of the three. Watch out for: day visitors. Arima is close enough that the lanes and the public baths fill up on weekends from late morning. Stay the night and bathe early or late.
Why it made it. Kinosaki Onsen is second at 3,955. It is the furthest of the three, and our estimate of about two hours is the most optimistic one here: the direct limited express takes about two hours and twenty minutes from Kyoto and about two and a half from Osaka. It still passes, and like Ogoto it can be reached on JR all the way.
The town. Kinosaki is built along a willow-lined canal, and the bathing happens outside your inn: there are seven public bathhouses, and guests walk between them in a yukata and wooden sandals in the evening. It is the most "onsen town" of the three in the sense most visitors mean.
The water. Kinosaki has one water type in our records, chloride, with sources from 37 to 83 °C. It is hot enough at source not to need heating, which is less common in Kansai than you might think; our guide to onsen near Kyoto and Osaka has the numbers.
Getting there. Take the JR limited express to 城崎温泉 (Kinosaki-Onsen) from Kyoto or Osaka. The JR Pass covers it. The station is at the edge of town, and the baths and inns are a short walk away.
Good for: anyone who wants a proper onsen-town evening, couples, and anyone with a JR Pass. Watch out for: the distance. It is a whole-day trip, not an add-on, and it fills up on winter weekends. Our Kinosaki guide covers the seven baths, the pass and the trains in detail.
Why it made it. Ogoto Onsen is third at 3,400. It is the closest of the three to Kyoto: our estimate is under an hour, and the train is JR all the way.
The town. Ogoto is a strip of hotels on the western shore of Lake Biwa, Japan's largest lake, facing east over the water. It is a stay-in-your-hotel place rather than a walking town. Our records list nine inns and about 490,000 bathing visitors a year. What is nearby is the reason to pick it: Hiyoshi Taisha shrine is 3.5 km away, and Enryaku-ji, the temple complex on Mount Hiei, is 5.2 km. It pairs well with a day of temples on the Kyoto side.
The water. Ogoto is a simple spring at pH 8.58, mildly alkaline and smooth on the skin. It leaves the ground at 30 °C, so the baths are heated. That is normal here and not a reason to skip it, but it is a different thing from Arima or Kinosaki; the water sign in the changing room tells you how each bath is run.
Getting there. Take the JR Kosei line from Kyoto to おごと温泉 (Ogoto-Onsen). The JR Pass covers it. Our route data lists a short walk from the station; ask your hotel how best to reach it, since the hotels are spread along the shore.
Good for: a Kyoto-based trip, an easy last night before flying out, a lake view from the bath. Watch out for: there is no old town centre to wander, and the water is heated. Part of Ogoto is also an adult-entertainment district, separate from the lakeside hotels; it does not affect a hotel stay, but it is why the name sometimes raises an eyebrow in Japan.
Dorogawa in the mountains of Nara came fourth at 2,118, about two hours out with no car needed. It is a small, quiet village at the foot of Mount Ōmine with a simple spring recorded at 26 °C — a mountain retreat more than an onsen town. Awara in Fukui was fifth at 1,923, with salt water from 33.5 to 77.5 °C. Sakakibara in Mie was sixth at 1,606, a simple spring at pH 9.5.
Gero in Gifu is more looked up than Dorogawa, at 2,959, with an 84 °C alkaline simple spring. It failed the time test: our estimate is about two and a half hours. If you are coming from Nagoya instead, it is a much closer trip.
The three Kaga towns in Ishikawa — Katayamazu (1,394), Yamanaka (1,329) and Yamashiro (1,120) — are about an hour and a half away, but in our data they do not pass the no-car test. Nanki-Shirahama, the big beach resort in Wakayama, is about three hours out in our estimate; our Kansai water guide covers it and the Kumano towns beyond.
