Yuneru at Shin-Narashino: Baths, Bedrock Spa and Overnight Cabins
Compare Yuneru’s bath, bedrock-spa, late-night and cabin options. Includes natural spring details, prices, station access and its conflicting tattoo guidance.
Updated September 2026
Natural hot spring, manga, bedrock baths, work-friendly seats and overnight cabins all sit under one roof at Yuneru, a large bathing facility beside JR Shin-Narashino Station. It opened in 2019, so “new generation” describes its mix of uses rather than a recent opening. The useful choice is how long you plan to stay: a quick bath, a longer visit with the bedrock area, a late-night rest, or a booked cabin.
Pick the ticket around your time there
| Plan | Adult price listed | Includes |
|---|---|---|
| Bath admission | ¥1,050 weekdays; ¥1,150 weekends and holidays | Baths and general rest areas; towels cost extra |
| Bath plus bedrock spa | ¥1,450 weekdays; ¥1,650 weekends and holidays | Admission, bedrock area and the longer-stay facilities |
| Deep-night pack | About ¥3,250 on weekday nights; ¥4,100 on Friday, Saturday and nights before holidays | Overnight public rest area; not a cabin or bedrock-bath ticket |
| Cabin stay | Date-dependent | A separate, bookable sleeping unit |
The listed towel set is ¥300 if you do not bring your own. The fee page may show pricing in a graphic and special dates can differ, so confirm the total on Yuneru’s current price page before visiting.
If you expect to stay three hours or more, the bedrock plan’s relatively small weekday difference can be worthwhile: it gives you room to pause between baths, read, rest and return to the bathing area. On a short stop, stick with the basic ticket.
What is natural spring water here?
Yuneru draws its natural spring from roughly 1,100 metres underground. The facility describes it as a salt-rich sodium-chloride spring and identifies an outdoor bath as source-fed. Other pools—including the artificial carbonated bath, rotating daily bath, reclining bath and jet bath—have different purposes and should not all be labelled as the same natural spring.
The appeal is as much about the time between baths as the soak itself. The facility lists around 20,000 manga, Wi-Fi, work seats, food service and a bedrock area with additional reading and rest space. Friends can split up for a while and meet again over a meal. The public baths remain gender-separated, however; the shared lounges are not mixed bathing.
Staying after 1 a.m. is not the same as booking a cabin
The deep-night pack is added when a guest remains in the facility after 1 a.m. It includes a towel set and indoor wear, and lets you use the shared reclining and book areas. It does not include the overnight cabins or the bedrock-bath area. The facility does not allow guests on these day-use plans to leave and return as if they were staying at a hotel.
Yuneru has 106 cabins—60 in the men’s area and 46 in the women’s area. Check-in procedures start at 10 a.m., cabin access begins at 3 p.m., and checkout is by 10 a.m. These are gender-separated cabins rather than conventional private hotel rooms. See the facility’s accommodation page if privacy or a specific sleeping arrangement matters.
Day-use guests cannot treat the building like a hotel with free exit and re-entry. Before leaving to eat or meet someone, check the terms for your ticket; a late-night pass is access to shared rest space, not a room reservation.
Getting there could hardly be simpler
Yuneru is about a one-minute walk from JR Shin-Narashino Station, on the Keiyo Line. That makes it an easy stop after a Makuhari event or along a journey through western Chiba. For a traveller staying in central or western Tokyo, the cross-city trip may take longer than the bath itself; the location works best when your plans already run along the Keiyo Line.
Opening hours, day-use procedures and facility details are on Yuneru’s official site.
Tattoo policy needs a phone call first
Yuneru’s pages do not give a consistent answer. Its fee-page notice says guests with tattoos or tattoo stickers are not admitted, while the FAQ and a separate tattoo notice describe an exception when tattoos can be completely covered with the facility’s specified cover stickers. Anyone who needs that exception should contact Yuneru before travelling and confirm the current sticker size, number allowed and which areas they may use. Do not rely on the exception without checking.
The notice has listed several sizes, including a 13 × 8 cm extra-large cover for ¥400 and a 10 × 6 cm large cover for ¥250. Those published sticker details do not resolve the contradiction in the entry rules, so get confirmation from the facility for your visit date.
The facility also regularly runs anime, game, local-business and character collaborations. That speaks to its event-led, social atmosphere, not to the spring itself; a quiet, low-stimulation bathhouse may suit you better on a collaboration weekend.
For a different kind of extended spa visit, Maihama Eurasia after its 2026 renewal has a co-ed sauna floor but no manga-and-cabin setup. Makuhari Yuraku no Sato is a better match when the outdoor bay view is the main draw.
