Kamisu Onsen Argo-no-Yu, Toyonaka
神州温泉 あるごの湯（豊中）
A big bath complex on the Kanzaki River in Toyonaka, about 20 minutes north of Umeda, whose main draw is an authentic Korean-style jjimjilbang — rare in Kansai. Sauna fans rate it highly for the large natural-spring open-air bath, cut-stone bath, pot baths, a sauna with löyly sessions every two hours, cold plunge and plenty of chairs and loungers for outdoor rest. The extra-charge 'Bijōbō' zone offers several low-temperature sauna rooms at 40–70 °C and a dome-shaped hanjeungmak at around 100 °C — Korea's steam-bath culture in Osaka. Entry: adults ¥900 on weekdays, ¥1,000 on weekends and holidays; children ¥500/¥550. Open 10:00–02:00 (last entry 01:00), every day. Besides 1,200 free parking spaces, free shuttle buses run from Hankyū and Kita-Osaka Kyūkō stations, so it is easy without a car. Restaurant, body care and relaxation rooms on site; being close to Itami Airport, it is a good place to kill time before or after a flight. Very busy on weekends and holidays.

A giant onsen plus chimbulbang in northern Osaka, open until 2 a.m.
Kamisu Onsen Argono-yu is a very large super-sento in Toyonaka, Osaka, attached to a big commercial complex in the Shin-Osaka and Mikuni area. Among the largest near Osaka, with parking for about 1,200 and a free shuttle, it is convenient for rental-car and business travellers alike. The bathhouse has two indoor baths and two broad rotenburo, a carbonated bath, three pot tubs, a plunge, an 88°C three-tier sauna with loyly service every two hours, and a salt sauna — suiting those who want both onsen and sauna taken seriously. The water is a soft alkaline-family spring carried from the natural outdoor onsen 'Spa Suminoe', colourless to faintly tinted with little irritation, good for a long soak and especially refreshing with the breeze of the rotenburo. The facility's other feature is a Korean-style 'chimbulbang' bedrock bath for an extra fee, with two hanjeungmak kilns and five rooms, robe and towel included — one of the few places in Osaka where you can have 'chimbulbang and onsen in one day'. At ¥900 for adults on weekdays and ¥1,000 at weekends it is reasonable for its size and facilities, and shampoo, rinse, body soap, hair dryer, shoe lockers and changing lockers are all free, so you can drop in empty-handed. Open every day from 10 a.m. to 2 a.m. (last entry 1 a.m.), it works for a 'final bath' late at night after sightseeing in central Osaka, or as a mid-point on days moving to and from Kansai or Itami airports. Weekends and evenings are crowded and weekday mornings most comfortable, and being 20 minutes by car from Shin-Osaka and Umeda it fits easily into any day of an Osaka itinerary.
Using onsen, sauna and chimbulbang in three stages
Park in the attached complex's car park (about 1,200 spaces) or arrive from Mikuni Station or the free shuttle, and pay at the entrance (¥900 on a weekday). Shoe and changing lockers are free, and shampoo, rinse, body soap, hair dryer and cotton buds are all provided, so you need almost no luggage. The bathhouse has two indoor baths (main tub, electric bath and others), two broad rotenburo outside the door, a carbonated bath, three pot tubs and a plunge, with an 88°C three-tier sauna (loyly every two hours) and a salt sauna at the back. A recommended circuit: wash and soak 10 minutes in the spring; sauna 8–10 minutes, plunge 1 minute, then 5–8 minutes on the open-air chairs in the rotenburo, three sets; finish with the salt sauna; and rest in a pot tub in the breeze. The water is a soft alkaline spring, colourless to faintly tinted, with little irritation, and the broad, breezy rotenburo makes open-air cooling especially pleasant. If you have time, add the chimbulbang (+¥900 on weekdays): a robe and towel are issued, there are two hanjeungmak kilns and five rooms at different temperatures, so you can follow the Korean course of two or three 45-minute rounds with sikhye and baked eggs (check availability) in the rest room. There is a restaurant and rest room for a meal afterwards, and with hours until 2 a.m. (last entry 1 a.m.) many people come for a 'night onsen' after dinner in central Osaka. Notes: weekends and evenings are crowded (waits for the sauna); the chimbulbang costs extra; reception closes after 1 a.m.; no bathing after drinking; check the tattoo policy. It is the most convenient place in northern Osaka to enjoy 'onsen, sauna and chimbulbang' together until late.
