Sleep
Exact rooms to book
Published room capacity and bed-sharing allowances are separate. Enter every child and age when you search, even if a child will share a bed.


These are room examples from the Ikyu.com listing. They may not show the exact room type recommended below; match the room name before booking.
Deluxe Twin
Best for four guests when parents prefer lower beds over a bunk
- Room size
- 35.6 m² / 383 sq ft
- Maximum occupancy
- 4 guests
- Beds
- 2 main beds · 110 cm × 206 cm · plus 2 additional beds · 110 cm × 192 cm and 114 cm × 192 cm
- Bathroom
- The official room page shows the bathroom layout; confirm the exact category if a washing-area bath is essential

- Maximum occupancy

Watch-outs
Things to know before booking
Check these conditions before you pay, especially when a child will share a bed or use hotel facilities.
Age 6 is paid for the room but free at breakfast
The hotel charges guests aged 6 and older as adults for accommodation, while its breakfast page currently lists children aged 6 and under as free. Enter the age accurately and check the final plan price.
Children using diapers cannot enter the public bath
Use the guest-room bathroom instead. The room TV shows public-bath congestion, so you can check before leaving the room.
Four-person room does not always mean four prepared beds
In the Deluxe Twin, extra beds are installed according to the number of paid adults or bed-using guests. Include every child who needs a bed.
Shiomi is served by local Keiyo Line trains
Some faster trains do not stop at Shiomi. Check the stopping pattern before boarding with luggage or tired children.
Child policy
What changes with age
Lodging, bedding and breakfast do not always use the same age boundary. Check the row that matches the child's age at travel.
Sleep A child under 6 may share an existing bed free. One free-sharing child still needs to be entered in the reservation.
Bedding Baby cots and bed guards can be requested but are limited; confirm compatibility with the selected room.
Meals Breakfast is free for children aged 6 and under.
Request the cot or guard in advance and plan on the room bath if the child uses diapers.
Sleep A child under 6 may share an existing bed free.
Bedding If the child needs a separate bed, count them as a bed-using guest so the hotel prepares it.
Meals Breakfast is free for children aged 6 and under.
Choose bed-sharing or bed-using explicitly; do not infer the setup from the room's maximum occupancy.
Sleep Accommodation is charged at the adult rate from age 6, so the child needs a separate sleeping place.
Bedding Select a four-sleeping-place room for a family of four rather than relying on bed-sharing.
Meals The current buffet page lists age 6 and under as free.
Enter age 6 as a paid guest and verify that the rate plan preserves the published breakfast exception.
Sleep A separate paid bed is required at the adult accommodation rate.
Bedding Use the Deluxe Twin for four lower sleeping places or the Family room only when the bunk is suitable.
Meals Breakfast is currently ¥2,500 for ages 7–12.
Include the child in room occupancy and confirm whether breakfast is included or paid separately.
