880 yen on the menu is 880 yen at the till

The conclusion: in Japan, prices shown to consumers must be displayed with consumption tax included. Which means the structure of the price leaves no slot for "an amount you add afterwards".

Everything below comes from the Ministry of Finance's own guidance on total-price display.

So the price a traveller sees in Japan is already the final amount. "Round it up and leave the difference" or "add 10% of the total" does not fit the way these prices are built.

⚠ That does not mean nothing is ever added. The duty to display tax-inclusive prices is not a rule against charging a service charge separately. Some restaurants and hotels do add one. That is the next section.

The service charge is in there from the start

The conclusion: in Japan the "extra for service" is designed in from the beginning as a contractual line item, not as an optional gratuity. That is why there is nothing to add later.

• The model hotel accommodation terms published by the Japan Tourism Agency (MLIT), Appended Table 1, "Breakdown of accommodation charges", splits the guest's total into (1) the basic room charge, (2) a service charge ((1) × %), (3) extra food and drink, (4) a service charge ((3) × %), and taxes (consumption tax and bathing tax)
• These model terms date from 1985 (23 December, Showa 60) and were last revised on 13 December 2023. ⚠ They are a "model" offered by the state: whether to adopt them is each property's decision. Your final terms are the ones in that property's own document
• In practice, the large travel agency JTB explains in its official FAQ that its own prices are, "with some exceptions, shown including consumption tax and the service charge"
• ⚠ The same explanation adds that "taxes such as the bathing tax, and the lodging tax in areas that levy one, are not included". That is exactly what lies outside the displayed price

One part of this bites only for large families. The service charge is a percentage of the basic room charge ((1) × %), so a family taking more rooms is already paying proportionally more service charge. Without adding anything, you have already paid in proportion to your party.

⚠ Some restaurants do add a service charge separately. Whether it kicks in at a certain party size, and at what percentage, varies from place to place; there is no publicly fixed standard. If you are unsure about the bill, check the foot of the menu before ordering.

What sits outside the price is tax, and only tax

The conclusion: outside the displayed price there are two taxes, the bathing tax and the lodging tax. Both are flat amounts per person per night, so for a large family they multiply straight through. (That some restaurants and hotels add a separate service charge is covered above.)

• The bathing tax (nyūtōzei) is an earmarked tax levied by municipalities that have hot spring bathhouses. Article 701-2 of the Local Tax Act provides that "the rate of the bathing tax shall be standard at 150 yen per bather per day", and each municipality sets the actual rate by ordinance (the revenue goes to environmental sanitation facilities, the protection and management of hot spring sources, fire services and tourism promotion). It is not included in the displayed room rate, so you pay it separately
• The lodging tax (shukuhakuzei) is levied by individual municipalities. According to Nagasaki City's official site, since 1 April 2023 the city charges, per person per night, 100 yen where the room rate is under 10,000 yen, 200 yen from 10,000 to under 20,000 yen, and 500 yen at 20,000 yen and above. There is no exemption threshold (participants and supervisors on school trips are exempt)
• Both are flat per person, so they scale directly with your party. A family of seven spending two nights at a property under 10,000 yen a night pays 100 yen × 7 people × 2 nights = 1,400 yen in Nagasaki City lodging tax alone. Move up a grade of hotel and the same seven people over the same two nights can be paying several thousand
• You do not need to tip, but you do need these two. Budget your accommodation with "a few hundred yen per person per night × people × nights" added on top
• ⚠ How children are treated differs by municipality. JTB notes the same thing in its own small print: "the treatment of the bathing tax for children differs from municipality to municipality"
• On the lodging tax, Nagasaki City's approach is that "a stay with no accommodation charge is not taxed". The city's Q&A states explicitly that where one preschool child per adult stays free sharing a bed, no lodging tax applies to that child (if a second child is charged 3,000 yen to share, the tax is calculated on that 3,000 yen). The more of your children sleep in shared bedding, the more this matters
• ⚠ That, though, is Nagasaki City's treatment. It is exactly the sort of thing that grows with party size, so check with the property or the municipality's official page before booking

⚠ The lodging tax differs by municipality, and some do not levy one at all. Neither the rates nor the bands are the same everywhere. This guide uses Nagasaki City only as an example, and it does not represent the amounts charged elsewhere.

And because these two may have to be paid on the spot, they affect how much cash you should be carrying when you arrive. Splitting payments between cash and an IC card matters more the larger the party — see Cash and IC cards in Japan.

The tax rates themselves (the 8% reduced rate against the 10% standard rate) are covered in How to use a Japanese convenience store, and tax-free shopping in Japan's tax-free shopping changes in November 2026.

Children's rates and where "free if sharing" comes from

The conclusion: the same table in those model accommodation terms (Appended Table 1) also sets out children's rates. And children given neither bedding nor meals are deliberately left to the property's discretion.

• The notes to Appended Table 1 of the Japan Tourism Agency's model terms apply children's rates to elementary school age and below, then set them at 70% of the adult rate where meals and bedding equivalent to an adult's are provided, 50% for a child's meal and bedding, and 30% for bedding only
• It continues: "for infants provided with neither bedding nor meals, the (infant charge) shall be received", with a parenthetical note limiting this to "hotels and ryokan that set an infant charge"
• In other words, at a property that sets no infant charge, it is zero. That is the mechanism behind what is usually described as "free if the child shares the bed" (sleeping in the same bedding as an adult, with no extra bed)
• Sharing free is each property's own decision, not an industry-wide rule. Two properties both listing "capacity 6" can differ: one counts a bed-sharing child on top of that capacity, the other inside it. Line up real listings and you find both kinds

This is where large families come unstuck reading only the numbers on a booking site. Read the note under the capacity figure, not the figure itself.

Seven people is not a "group"

The conclusion: the larger the booking, the more the cancellation terms deserve reading before you commit. A percentage applied to six or seven people's accommodation moves a lot of money for the same percentage.

• Appended Table 2 of the model terms (cancellation charges) leaves the percentages themselves blank. Each property sets its own; there is no "usual rate"
• The same table divides bookings by party size. The hotel version reads "general: up to 14 people / group: 15–99 / 100 and above", while the ryokan version is banded "up to 14 / 15–30 / 31–100 / 101 and above". The bands differ, but both start with "up to 14". A family of seven falls on the same side as any ordinary guest in either table
• ⚠ Again, this is a model, so where the line actually falls is settled by each property's own terms. One cannot say that no property treats six or more as a group. If it matters, read the terms before booking
• For large bookings, the day the cancellation charge starts (how many days ahead) also varies by property. If your flights cannot be changed, look at that first

What to do instead of tipping

The conclusion: thanks are given in words, not cash. The Japan National Tourism Organization (JNTO) also states on its official site that tipping is not customary in Japan.

• The settings JNTO lists are bars, cafés, restaurants, taxis and hotels — that is, almost every situation you meet while travelling
• At the till, these two phrases are enough: "arigatō gozaimashita", and after a meal, "gochisōsama deshita"
• JNTO gives one exception: "a private guide or interpreter used to overseas customs may accept a tip"
• Even the etiquette for insisting is described officially: put it in an envelope and offer it discreetly. Small cash envelopes are sold at convenience stores, stationery shops and 100-yen shops (JNTO). If you remember one thing, make it this: do not hand over bare cash
• You may read about leaving a gratuity at a ryokan, but it varies by property and region. Not giving one is never rude.
