Solaniwa Onsen Osaka 2026: Prices, Tattoo Rules and How It Works

Short answer: Solaniwa Onsen Osaka Bay Tower costs ¥2,310–¥3,630 for adults depending on the date (¥1,980 from 5pm on type A/B days), plus ¥150 bath tax, with yukata and towels included. It’s open 11:00–23:00, linked to Bentencho Station, takes walk-ins, and allows tattoos only if fully covered with stickers sold at the desk.

Adult entry to Solaniwa Onsen Osaka Bay Tower costs ¥2,310–¥3,630 (about US$15–23) depending on the date, or ¥1,980 if you arrive after 5pm on a cheaper day, plus a ¥150 bath tax. Most people stay 3–4 hours. It’s in the Osaka Bay Tower complex, linked by a walkway to Bentencho Station (JR Loop Line and Osaka Metro Chuo Line), and you can walk in without booking or buy a voucher online from the official site, Klook or other platforms.

Think of it as an onsen theme park, not a quiet country bathhouse: nine baths, a 3,000 m² rooftop garden you stroll in a yukata, festival games, bedrock saunas and a food hall. This guide covers what each ticket costs, how the tattoo sticker rule works, what happens from shoe locker to checkout, and when to go to beat the crowds.

What is Solaniwa Onsen?

Solaniwa Onsen Osaka Bay Tower (空庭温泉, “sky garden hot spring”) is a large day spa in the low-rise Bay Tower North wing of the Osaka Bay Tower complex, next to the 200-metre tower above Bentencho Station. It opened on 26 February 2019. The theme is Azuchi-Momoyama-era Osaka: the late 16th century, when Osaka Castle was built. The building is laid out like an old town, with a festival street, shrines and a food hall.

The water is pumped from 1,000 metres underground (official facility page). It’s a real onsen, not heated tap water.

Who it suits: Visitors who want a first onsen with English signs and no awkward rules to guess. Groups of mixed genders, because the garden, foot bath, food and games are shared areas in yukata. Families: children 4–12 pay a flat ¥1,320.

Who it doesn’t suit: Anyone after a quiet rural ryokan bath with a mountain view. The view here is a garden and the tower, and weekends get busy. For that kind of trip, see our best onsen towns in Japan.

How much is Solaniwa Onsen? 2026 prices

The price depends on the “ticket type” (A to E) assigned to each date. The official price page publishes the types on a monthly calendar rather than as a weekday/weekend rule. Check the calendar for your date before you go.

The October–December 2026 calendar follows a clear pattern. Most Mondays to Thursdays are type A (¥2,310), Fridays are type B (¥2,640), and Saturdays, Sundays and public holidays are type C (¥3,080). Three-day holiday weekends are type D (¥3,300): 10–12 October and 21–23 November. The weekdays from 21 to 28 December are type B, and 29–31 December is type E (¥3,630). The first week of October was type B on weekdays, so don’t assume the pattern holds every month.

Ticket	Type A	Type B	Type C	Type D	Type E
Adult (13+)	¥2,310	¥2,640	¥3,080	¥3,300	¥3,630

What else you’ll pay:

• Bath tax: ¥150 per adult, paid on site. Children of elementary-school age and under are exempt.
• Private open-air baths: ¥8,800 (standard room), ¥12,100 (Japanese-style tatami room) or ¥15,400 (Western-style room with tent sauna) per room for 90 minutes. Entry fees are charged on top.
• Extras: A second yukata, bedrock-sauna outfit or towel is ¥220 each. Coin lockers for luggage are ¥600, and staffed bag storage is ¥770 per item (FAQ).

Which ticket should you buy? Options compared

1. Standard admission at the door (Day ticket)

The Lowdown: Walk up, get a wristband key, and settle up on the way out (recent visitors report paying the whole bill at checkout). No booking needed and no time slot. You get the baths, garden, foot bath, lounges and yukata.

Where: Reception at the Solaniwa entrance, reached by the walkway from JR Bentencho Central North gate.

The Vibe: Busy and sociable. Families, couples and groups of friends in matching yukata.

Price: ¥2,310–¥3,630 by ticket type, plus ¥150 bath tax.

Official Link: solaniwa.com/en-us/price

💡 Japan Pro Tip: Type D and E dates don’t get the evening discount, so a holiday-weekend evening costs the full rate. If your dates are flexible, check the calendar and move your visit to a type A or B day. It saves up to ¥1,650 per adult.

2. Evening admission from 5pm (Late entry)

The Lowdown: The best value in the building. On type A and B days, entry from 17:00 is ¥1,980. Baths stay open until 22:30, so you still get over five hours.

Where: Same entrance and reception.

The Vibe: The garden is lit up after dark, and the families with small children start heading home.

Price: ¥1,980 (types A/B) or ¥2,420 (type C). Not offered on D/E days. It can’t be combined with other discounts.

Official Link: solaniwa.com/en-us/price

💡 Japan Pro Tip: In November and December it’s dark by about 5pm, so a 17:00 arrival gets the garden lights from the start. Have dinner in the food hall instead of paying for a meal in Namba first.

3. Online vouchers (Klook, Headout, Kansai Joy Pass)

The Lowdown: Platforms sell admission from around US$14.39 (roughly ¥2,260), plus bundles with a meal, bedrock sauna or festival games. You show a QR code at reception instead of paying for entry at checkout.

Where: Same reception. Private-bath vouchers are redeemed at the private bath desk on the 2nd floor, next to the bedrock sauna reception.

The Vibe: Convenient if you’re already holding a multi-attraction pass. WAUG’s Kansai Joy Pass lists Solaniwa as one of its choices (alongside Harukas 300), but only for type A and B dates: on C, D and E dates you pay the difference at the venue. Check the current attraction list before you buy.

Price: From about US$14.39 for admission only on Klook on 29 October 2026. Bundles run about US$23–37. The ¥150 bath tax is still paid on site.

Official Link: The official web tickets are at ars-solaniwa.triplabo.jp (linked from the official price page).

💡 Japan Pro Tip: Compare like for like. At ¥157 to the dollar, US$14.39 is about ¥2,260, only around ¥50 under the ¥2,310 type A door price, and nothing beats the ¥1,980 evening rate on A/B days. Vouchers save more on C–E days or as a bundle you’d buy anyway. Platform prices can change by date, so check yours. On Klook’s private-bath packages, free cancellation ends at 23:59 the day before.

4. Bedrock sauna add-on (Ganbanyoku)

The Lowdown: Seven heated-stone rooms in the Neppu Yokocho area, where you lie on warm rock in a special outfit. The Jingu-bo room has a projection-mapped löyly (steam) show.

Where: Sign up at the Bedrock Sauna Reception beside the front desk on the 2nd floor. The outfit and a large towel are included in the fee.

The Vibe: Mixed-gender and clothed, so couples can use it together. Quieter than the baths.

Price: ¥1,100 (A/B days) or ¥1,320 (C/D/E days), on top of entry. Adults only.

Official Link: solaniwa.com/en-us/explore

💡 Japan Pro Tip: Event sessions change monthly. September 2026 had weekday heat sessions at 15:30 and 19:00, for example. Check the news page on the day and plan your bedrock sauna around the next show.

5. Private open-air bath (Family or tattoo-friendly option)

The Lowdown: Ten private outdoor baths with mini gardens, booked for 90 minutes. They’re the answer if your family wants to bathe together, or if your tattoos are too large to cover with stickers. Mixed male and female use is limited to families (official facility page), so a mixed group of friends can’t share one.

Where: Private bath reception, 2nd floor. Check in and change into your yukata first, and arrive about an hour early, as the official FAQ advises.

The Vibe: Your own bath, your own garden, no one staring.

Price: ¥8,800 (standard, 1–4 people), ¥12,100 (Japanese-style, 4–6 people), ¥15,400 (Western-style with tent sauna), per room for 90 minutes. Extensions run from ¥2,750 per 30 minutes if free. Each person also pays entry.

Official Link: solaniwa.com/en-us/price

💡 Japan Pro Tip: Split four ways, a standard room adds ¥2,200 each. For a family with young children, that’s often less stress than separate male and female baths. The Western-style room with the tent sauna is the wheelchair-accessible one (FAQ).

Can you go to Solaniwa Onsen with tattoos?

Only if you can cover every tattoo completely with the stickers sold at the facility. The official wording: “As a general rule, we do not allow those with tattoos or other kinds of body art.” Guests who cover their tattoos fully with the cover stickers sold on site may enter and bathe. Since 1 December 2023 there’s no limit on the number of stickers (official FAQ). The rule covers body paint and fashion tattoos too.

What that means in practice:

• A small wrist, ankle or shoulder tattoo: buy stickers at the front desk, stick them on and bathe as normal. In 2022 the stickers cost ¥100–¥400 depending on size, with each sticker up to about 10 × 14.5 cm and a limit of five (Japan Today/SoraNews24). The five-sticker limit has gone. Current sticker sizes and prices: TBA. Solaniwa’s English and Japanese FAQs don’t publish them (checked 29 October 2026), so ask at the desk.
• A sleeve or back piece: in theory unlimited stickers solve this, but they have to stay on through hot water and steam. Book a private open-air bath instead (alone, with same-sex friends or with family).
• Covered by a sticker means covered. Staff can refuse entry if a sticker peels off and a tattoo shows.

What happens at Solaniwa Onsen? Step by step

0 min: arrive. From JR Bentencho, leave by the Central North gate and take the connecting walkway straight into Osaka Bay Tower. From the Metro, use the west gate and Exit 2A. Follow the Solaniwa signs.

Shoes off. Put your shoes in a shoe locker and keep the key.

Reception. Show a voucher QR code or just walk up. You get a wristband key. Recent visitors report that what you buy inside (food, drinks, games, the bedrock sauna) is charged to it, and that the full bill, including the ¥150 bath tax, is settled at checkout. The official FAQ lists cash, credit cards and barcode payments (PayPay, Alipay, WeChat Pay).

Pick a yukata. Choose your yukata (robe) and obi (sash) right after reception. Sizes run S to 5L for men and women. Take your outfit photos now, while your hair is still dry.

Change. Head to the changing area and put your clothes in the locker (included in the entry fee) and your yukata on. You’ll now be juggling a shoe locker key, a clothes locker key and the wristband, so a small pouch helps.

Baths (about 1 hour). The baths are separate for men and women. In the bath changing room you take everything off: swimsuits aren’t allowed. Wash at the shower stations before you get in. There are nine baths, indoor and outdoor, including a natural hot spring and a bath overlooking the garden.

Garden and foot bath (30–45 min). Back in your yukata, go out to the rooftop Japanese garden: more than 3,000 m², with a pond, waterfalls, a small Thousand Torii corridor, Benten and Koshin-do shrines and a long foot bath. This part is mixed, so meet up with the rest of your group here.

Eat and play (45 min). Kuidaore Yokocho is the food street, with festival-style stalls and a dining hall. There are also two cafés (Komachi-chaya and Tenga-chaya) and a covered outdoor terrace restaurant. Festival games such as target shooting and goldfish scooping are at the Benten Festival Corner, and there’s table tennis in the play area.

Lounge, then out. Recliners in the resting zone and a relaxation and body-care salon (extra charge) fill the rest of the evening. On the way out, return the yukata, collect your shoes and pay the wristband balance.

Whatever time you arrive, you can stay until closing. Allow 3–4 hours, and up to 5 if you add the bedrock sauna. Note that Klook’s terms say re-entry isn’t allowed once you leave.

What are the rules and etiquette?

• Wash first, bathe naked. No swimsuits. Small towels stay out of the water: put yours on your head or on the edge.
• Hair up. Long hair shouldn’t touch the water.
• No phones in the bath area. Take your photos in the garden and the yukata areas.
• Drink water. Hydrate between the baths and the bedrock sauna. The food hall serves beer, but don’t go back into hot water after drinking.
• Kids: Children 12 and under can’t enter without an adult. Under Osaka rules, groups of under-18s with no adult must leave by 22:00, and under-16s by 19:00 (FAQ).
• No overnight stays. Solaniwa has no accommodation, and the resting area currently closes with the building at 23:00. If you want to stay, the Art Hotel Osaka Bay Tower is upstairs.

What should you bring?

Not much. Bath towels, hand towels, yukata and toiletries are included. Bring:

• A hair tie and any skincare you’re attached to.
• Cash or a card. Some coin-operated machines may need cash.
• A small bag for keys and phone.
• Luggage? Coin lockers (¥600) or staffed storage (¥770) are on site, so you can come straight from Kansai Airport (about an hour away).

When is the best time to visit?

• Least crowded: Weekdays from 11:00, when it opens.
• Best value: 17:00 on a type A or B day, for ¥1,980. In winter, you arrive as the garden lights come on.
• Busiest: Weekend and public-holiday afternoons, Golden Week, Obon and the New Year holiday. These are also the C–E price days.
• Closed: Once a month, on a Wednesday. The remaining 2026–27 closure dates are 11 November 2026, 9 December 2026, 13 January 2027, 3 February 2027 and 10 March 2027 (official price page).
• Morning bath: The official price page lists a morning bath from 6:00 to 9:30 (last entry 8:30, baths until 9:00). It isn’t available on closure days or the day after. Price: TBA. Neither the English nor the Japanese price page publishes it (checked 29 October 2026), and the official FAQ only says the morning-bath fee is exempt from the ¥150 bath tax. Ask at reception before planning around it.
• Seasonal events: “Solaniwa Yokai Halloween” runs until 8 November 2026, with a kids’ keyword rally, a lantern-lit mystery trail in the garden and yokai dance shows on weekends and holidays (official notice). From 12 November 2026 to 6 April 2027, the covered outdoor terrace serves kotatsu hot-pot plans, entry included, from ¥6,110, or ¥5,417 if you book by 11 November (official notice). Check the official news before you go.

Solaniwa is all indoors or under cover, apart from the open-air baths and the garden, so it makes a good wet-weather plan for Osaka.

How do you get to Solaniwa Onsen?

From	Route	Time
Osaka / Umeda	JR Osaka Loop Line (inner loop, towards Nishikujo) to Bentencho	about 10 min
Universal Studios Japan	JR Yumesaki Line to Nishikujo, change to the JR Loop Line, 1 stop to Bentencho	about 15 min
Osaka Aquarium Kaiyukan	Osaka Metro Chuo Line from Osakako, 2 stops to Bentencho	about 5 min + 5–10 min walk to Osakako
Namba / Shinsaibashi	Metro Midosuji Line to Hommachi, change to Chuo Line to Bentencho	about 20 min
Kansai Airport	JR Kansai Airport Rapid to Bentencho (direct; the Haruka doesn’t stop here)	about 60 min

At JR Bentencho, use the Central North gate. The walkway to Osaka Bay Tower starts just outside it. At the Osaka Metro station, use the west gate and Exit 2A (official access page). There’s no free shuttle bus from Umeda or anywhere else. The official FAQ confirms there’s no pick-up service. Driving? The Osaka Bay Tower car park is paid.

An IC card works on every route above.

What can you pair with Solaniwa Onsen?

• Universal Studios Japan: The obvious one. After a full park day your legs will want this. Arrive any time after 17:00 (last entry 22:00) and you get the evening rate on A–C days. Plan the park day with our Universal Studios Japan tickets guide.
• Kaiyukan and Tempozan: Osakako is two stops away on the Chuo Line. Do the aquarium and the Tempozan Ferris wheel in the morning, then soak in the afternoon.
• Umeda: Ten minutes on the Loop Line. Bathe, then go to Umeda for dinner and the city views. Our Umeda guide has where to eat.
• With kids: The garden, games and flat child fare make this one of Osaka’s easier family days out. More ideas are in Japan with kids.

Conclusion

Solaniwa Onsen is the easiest first onsen in Osaka. It’s ten minutes from Umeda, takes walk-ins, and is built so a mixed group can spend an evening together. Check the ticket-type calendar, aim for 5pm on a type A or B day, and buy stickers at the desk if you have small tattoos. Then explore Japan Pro to plan the rest of your Osaka trip.
