Irifune suits a visit with time to try its different baths. Day-use guests choose an available private room on arrival; advance reservations are not accepted.

Two springs make Irifune more than a quick stop

Irifune uses two springs. One is a simple hot spring; the other is a sodium, magnesium and calcium sulfate spring. The inn describes one water as milky and the other as clear. Its bath layout also includes hotter and milder tubs, though it does not publish a fixed bathing temperature for each one.

Source readings and bath temperatures are not interchangeable

The source analysis does not give a safe, current figure for every bath’s temperature, so expect a difference in feel rather than a guaranteed number. Men’s and women’s baths change sides daily, which also means the same named bath may not be on the same side each visit.

Day-use prices, hours and September closures

Day-use detail	Information
Public-bath hours	1–9 pm; last admission 8 pm
Regular closing day	Wednesday; additional monthly closures may be announced
New Year hours	1–7:30 pm, December 31–January 3

Five private baths, one on-arrival decision

Family bath	Price per room	Session
Natural Rock	¥1,700	50 minutes
King	¥1,800	50 minutes
Swan	¥1,800	50 minutes
Tama-chan	¥2,000	50 minutes
Volcanic Stone	¥2,000	50 minutes

Day-use rooms are assigned on arrival, so a preferred bath is not guaranteed. If the rooms are busy, expect to wait or choose another one.

Winter adds another variable: when the water temperature is low, the inn may open only three of the five private baths. That can reduce the number of available rooms just when a cold day makes a private soak appealing. A public bath is the safer fallback if the private room you want is occupied.

Overnight guests have a different arrangement and may use the private baths during their stay without the day-use room charge. That lodging benefit does not apply to day visitors.

Day-use option	Price	Hours or conditions
Public bath, adult	¥600	1 pm–9 pm; last admission 8 pm
Public bath, child ages 3–elementary school	¥350	Same hours
Private family bath	¥1,700–¥2,000 per room	50 minutes; no advance reservation
Regular closing day	—	Wednesday; extra dates may be announced

Day-use payment is cash only. Cards and QR-code payment mentioned for overnight stays should not be assumed to work at the bath counter.

Getting there and planning the transfer

Irifune is at 834-2 Ozato, Aso City. From Aso Station, a taxi takes about ten minutes. There is no inn pickup. Local buses serve the Uchinomaki area; check the stop and return departure against the bath’s last admission before leaving the station. The inn has 25 free parking spaces for drivers.

Access for guests with limited mobility

The building is not fully step-free. Some level changes have handrails, but guest rooms on the second floor require stairs. The private-bath changing areas are described as small. Anyone who needs wheelchair transfer space, mobility equipment or a larger care area should ask the inn about the exact route and room before making the trip.

The car-free Uchinomaki half-day guide explains the local bus stops and return risk. For a town-bath alternative, compare the Uchinomaki bathhouses; for private-bath formats across the area, see Aso’s private-bath comparison.

Who Irifune suits—and when another bath is easier

Choose another bath if the only time available is before 1 pm, if you need a guaranteed private-bath reservation, or if your group cannot manage the steps and compact changing room. For a low-cost, quick soak, the ¥200 Shichifuku bath or ¥300 Ōaso bath costs less; those facilities have fewer amenities, so bring your own towel and wash items.

Tattoo rules are not clearly stated in the available day-use information. Check directly with the inn before travelling if this affects your choice. Hours, monthly closures and private-bath availability can change; confirm them for the date you plan to go.

The inn posted a separate earthquake and reopening notice on 28 July 2026. Treat that as a dated update, not a guarantee that every facility will operate unchanged on a future visit. Its September notice also lists an extra closure on 3 September, illustrating why the regular Wednesday closing day is not the whole calendar.

Frequently asked questions

What does Irifune’s public bath cost?

Adults pay ¥600; children aged three through elementary school pay ¥350. Day-use hours are 1–9 pm, with last admission at 8 pm, except for announced closure dates.

Can day visitors use a private family bath?

Yes. The five rooms cost ¥1,700–¥2,000 per room for 50 minutes. They cannot be reserved in advance for day use; ask at the inn what is available when you arrive.

Are all five family baths open in winter?

Not necessarily. The inn says that when the spring water is cold, only three of the five rooms may be open. If a private bath is the reason for your trip, contact the inn before setting out.

Do both springs use flow-through bathing?

The inn describes both sources and its bath areas as flow-through. One source is a simple spring and the other a sodium-magnesium-calcium sulfate spring. The available information does not give a reliable current temperature for each tub.

What is the spring temperature?

The cited spring analysis does not provide a safe current number for every bath, so this guide does not assign one. The inn describes hotter and milder tubs; source temperature and tub temperature should not be treated as the same measurement.

Can I pay by card?

The day-use information says cash only. Payment methods offered for overnight bookings do not confirm that cards or QR payments are accepted at the bath counter.

Does Irifune pick guests up at Aso Station?

No inn pickup is listed. A taxi takes about ten minutes. Check the bus stop and return departure before you travel to the Ozato area.

What are the New Year hours?

The inn lists shorter day-use hours of 1–7:30 pm from 31 December through 3 January. Check the current holiday notice before travelling.

Tattoo policy

The day-use pages do not clearly state whether tattoos are accepted. Ask Irifune directly about its current policy before visiting; do not assume the same rule applies to its public and private baths.
