On a Japanese hot spring trip, credit cards and e-money are becoming more widely accepted, but there are still many situations where cash is the only option. In short, even facilities that let you pay for lodging by card may still require cash for the bath tax, vending machines, coin lockers, shops, and public bath fees. This is especially true in rural areas and historic public baths, where cash-only operation remains common. For that reason, it is reassuring to have some cash ready before you arrive at a hot spring area.

If you come with almost no cash because you assume everything works like a card-based society, you may have trouble exchanging money or finding an ATM after you arrive. On the other hand, if you know in advance where cash is most likely to be needed, you can prepare only the amount you need in a city. This article organizes the likely payment methods by situation, how bath tax is settled, and how to secure cash at ATMs that support foreign-issued cards from the practical viewpoint of visitors to Japan. For booking-related checks beyond payment, see the onsen ryokan pre-booking checklist.

Please note that the tendencies mentioned here, such as “cards accepted” or “cash only,” are only general guidelines. Actual payment options vary by facility and region. Ultimately, please confirm with each facility’s official information before booking or visiting.

Payment methods by situation

To give you an overview, here is a list of common payment situations during a hot spring trip and the usual methods available in each case. The table below shows only general tendencies, and there can be large differences between facilities, even within the same category of public bath.

What this table shows is that even if you can pay for the accommodation itself by card, small payments during your stay are still likely to require cash. Having some cash on hand, especially coins, will greatly reduce the chance of trouble on site.

Situations where cash is likely to be needed

Even today, when card payments are widespread, there are many situations on a hot spring trip that still assume cash. Typical examples are payments at long-established ryokan or small day-use facilities, admission fees for public baths and outdoor baths, vending machines, coin lockers, and shops inside the building or in the hot spring town.

In particular, rural areas and historic public baths often still operate cash only. Outdoor baths that have existed in hot spring towns for a long time, or public baths managed by local communities, may ask for cash at an entrance fee box or a small ticket machine. Such facilities tend to be small, and they often continue cash-centered operations.

Coin lockers and vending machines are also situations where cash is often needed. Many lockers require coins such as 100 yen coins, and if you only have banknotes you may not be able to use them. Some facilities do not have a nearby change machine, so it is wise to have cash ready, including coins. Vending machines and small shops inside the building may also remain cash only.

In other words, even if your accommodation accepts card payments, that does not mean you will not need cash at all. The basic approach is to carry some cash and coins for small payments during your stay.

Situations where cards, e-money, or QR payments can be used

On the other hand, cashless payment support is steadily expanding. Large ryokan, hotels, super sento, and large day-use hot spring facilities in urban areas and tourist destinations increasingly accept credit cards, transit-type e-money, and QR code payments. Many facilities also accept foreign-issued credit cards.

At large ryokan and hotels, paying in advance by card through a booking site is also common. In that case, there is no need to handle the accommodation fee on site. However, as noted below, bath tax may not be included in the advance payment and may need to be settled separately at the facility.

That said, small facilities in rural areas may not support cashless payment. Even within the same hot spring area, it is completely normal for a large ryokan to accept cards while a nearby public bath accepts cash only. Rather than assuming either that “you can pay by card anywhere in Japan” or that “you need cash everywhere,” it is safer to understand that payment methods vary by facility. If you are worried, it is a good idea to confirm accepted payment methods with the facility you plan to use when booking or before visiting.

Bath tax is often settled in cash on site

In hot spring areas, a bath tax may be charged separately from the accommodation fee. Bath tax is a type of local tax collected by the municipality that has the hot spring from bathers. The standard amount is typically 150 yen per person per night, but the amount and handling vary by municipality.

What is important in practice is that bath tax is often settled in cash on site. Even if you thought you had fully paid your accommodation fee by card in advance, the bath tax alone may still need to be paid separately at the facility. This is because bath tax is not a service charge from the inn but a tax, and the inn collects it from bathers and pays it to the municipality. For overnight stays, it is usually settled together at checkout, including bath tax.

For that reason, even if you have prepaid your lodging by card, you may still need a small amount of cash at checkout. The bath tax system and tax-exempt cases are explained in detail in What Is Bath Tax?. Even though it is a small amount, having no cash at all can cause trouble when settling the bill, so it is a good idea to keep some small banknotes and coins on hand just in case.

How to exchange money and secure cash

To prepare for situations where cash is needed, the most reliable method is to have cash ready before heading to the hot spring area, ideally while still in a city. Hot spring towns are often in smaller communities, and once you arrive, ATMs may be limited or hard to find nearby.

ATMs that are easier to use for withdrawing cash with foreign-issued cards include convenience store ATMs and Japan Post Bank ATMs. These often support overseas-issued cash cards and credit cards, and some machines offer multilingual displays such as English. In cities, convenience stores are easy to find, so it is reassuring to withdraw a larger amount of cash before traveling to the hot spring area.

However, not every ATM supports every overseas card, and availability differs depending on the machine and the type of card. The international brands accepted and whether withdrawals are possible vary by ATM, so it is safer to have multiple options. If you arrive in a hot spring area and do not have enough cash, it may be difficult to obtain more, so we recommend preparing the amount you are likely to need while you are still in the city.

Tips are not needed

One payment-related point that often confuses visitors to Japan is tipping. The conclusion is simple: tips are not necessary at Japanese ryokan or bathing facilities. Unlike in restaurants or hotels in some Western countries, there is basically no custom of adding a tip as payment for service.

Even if staff such as nakai provide attentive service, there is no need to give an extra tip, and trying to do so may actually make the staff uncomfortable. If a service charge is required, it is generally already included in the lodging fee. For more on the difference from tipping cultures and the background, see Are Tips Necessary at a Hot Spring Ryokan?.

In other words, the cash you should prepare for a hot spring trip is for real payments such as bath tax, vending machines, lockers, shops, and public baths, not for tips. Understanding this will make it easier to estimate how much cash to bring.

FAQ

Can I use a credit card in hot spring areas?

It depends on the facility. Large ryokan, hotels, and super sento in cities and tourist areas increasingly support cards and e-money, but small rural facilities and historic public baths may still be cash only. Even within the same hot spring area, payment methods vary by facility, so if you are concerned, confirm in advance and bring some cash as well.

How much cash should I bring on a hot spring trip?

The amount depends on your itinerary, but it is wise to prepare for situations that often require small cash payments, such as bath tax, vending machines, coin lockers, shops, and public bath fees. Coin lockers in particular often require coins, so having small change will help. Even if your lodging is prepaid by card, that does not mean cash becomes unnecessary.

Can bath tax be paid by card?

Bath tax is a tax, and because the inn collects it from bathers and pays it to the municipality, even if you pay for lodging by card in advance, the bath tax may still need to be paid separately at the facility.

Where can I withdraw cash with an overseas-issued card?

Convenience store ATMs and Japan Post Bank ATMs are often compatible with overseas-issued cards, and some machines offer multilingual displays.
