Published: 2026-10-05 / Updated: 2026-10-05 ・ 6 min read

The Naoshima Onsen "I ♥ 湯" (read as "I Love Yu," with yu meaning hot water in Japanese) is a fully functional public bathhouse and art installation located on the art island of Naoshima. Designed by the renowned Japanese artist Shinro Ohtake, this striking venue allows visitors to soak in a hot bath while immersed in a colorful, eclectic world of collage art, retro pop culture, and unique sculptures.

For international travelers making the pilgrimage to Japan's famous art islands, a stop at this iconic bathhouse is a highlight. This guide covers everything you need to know to plan your visit, from transportation and costs to etiquette and what to pack.

What is Naoshima Onsen "I ♥ 湯"?

Created as part of the island's ongoing artistic rejuvenation, "I ♥ 湯" is a public bath (sento / 銭湯) that serves both local residents and global tourists. Shinro Ohtake transformed a traditional neighborhood bathhouse into a living canvas.

The exterior is a vibrant collage of salvaged neon signs, painted tiles, and exotic flora. Inside, the visual feast continues. The bathhouse is divided into a male side and a female side. Dividing the two bathing areas is a massive, life-sized statue of an elephant standing atop the partition wall. The bottom of the mosaic-tiled baths features underwater dioramas, pin-up graphics, and intricate tile work that you can admire while soaking.

How to Get to Naoshima Onsen

Naoshima is located in the Seto Inland Sea. To reach the island, most travelers take a ferry from either Uno Port (宇野港) in Okayama Prefecture or Takamatsu Port (高松港) in Kagawa Prefecture.

• From Okayama (Uno Port): Take the JR Uno Line from Okayama Station to Uno Station (roughly 45 to 60 minutes). Walk across the street to Uno Port and take the ferry to Miyanoura Port (宮浦港) on Naoshima (around 20 minutes). You can use regional passes from JR West to reach Uno Station.
• From Takamatsu Port: Take a ferry or high-speed boat directly to Miyanoura Port (around 30 to 50 minutes depending on the boat type).

Once you disembark at Miyanoura Port, Naoshima Onsen "I ♥ 湯" is incredibly easy to find. It is located in the village just behind the ferry terminal.

• Walking time: It takes roughly two to three minutes to walk to the bathhouse from the port.
• Visual cues: Look for the tall, colorful chimney and the glowing neon "I ♥ 湯" sign rising above the traditional wooden houses of the neighborhood.

Admission Prices and Opening Hours

Because "I ♥ 湯" is a community bathhouse, the admission fee is highly affordable, usually costing under 1,000 yen for adults. Children receive discounted entry.

• Opening Hours: The bathhouse generally opens in the mid-afternoon and closes in the mid-evening. It is typically closed on Mondays (or Tuesdays if Monday is a national holiday).
• Important Tip: Hours, prices, and scheduled maintenance closures can change unexpectedly. Always consult the official Benesse Art Site Naoshima website before your trip to confirm the current schedule.

The Tattoo Policy at Naoshima Onsen

One of the most common concerns for international travelers visiting Japanese hot springs (onsen) and public baths (sento) is the strict policy regarding tattoos. Many traditional venues prohibit body art entirely due to historical associations.

Fortunately, Naoshima Onsen "I ♥ 湯" is exceptionally welcoming. Tattoos of all sizes, colors, and designs are fully permitted here. You do not need to cover them with stickers or bandages. This makes the bathhouse an excellent, stress-free destination for tattooed travelers who want to experience authentic Japanese bathing culture.

What to Bring and What to Wear

Unlike luxury ryokan baths, a neighborhood public bathhouse expects you to bring your own supplies, or buy them on-site.

• Towels: You must bring your own bath towel and a small washcloth. If you forget, you can purchase exclusive, artist-designed towels at the front desk. These make fantastic, practical souvenirs.
• Toiletries: Body soap, shampoo, and conditioner are not automatically provided at the washing stations. You can bring your own travel-sized bottles, or purchase small, single-use packets at the entrance.
• Cash: The ticket vending machine at the entrance typically only accepts Japanese yen cash (coins and small bills). Ensure you have physical currency on hand before arriving on the island, as ATMs can be limited.
• Clothing: There are no special dress codes for arrival, but you will strip entirely naked before entering the bath area. Swimsuits are strictly prohibited.

Step-by-Step Guide to Bathing Etiquette

If you have never visited a Japanese public bath, the process can feel intimidating. Follow these simple steps to ensure a smooth, respectful visit:

1. Remove your shoes: As soon as you step inside the entrance, remove your outdoor footwear and place them in the shoe lockers.

2. Purchase your ticket: Use the ticket vending machine to buy your admission ticket and any toiletries or towels you need. Present your ticket to the staff member at the counter.

3. Enter the correct changing room: The entrance to the bathing areas is separated by gender. Look for the blue curtain (usually marked with the kanji 男 for men) and the red curtain (usually marked with the kanji 女 for women).

4. Undress completely: Place all your clothing, jewelry, and large towels into the provided baskets or lockers in the changing room. You should only carry your small washcloth into the bathing area.

5. Wash thoroughly before soaking: Do not step directly into the hot bath. Sit on one of the small plastic stools at the washing stations along the wall. Use the handheld shower, bucket, and soap to wash and rinse your entire body completely.

6. Rinse off all soap: Make sure no soap residue remains on your body or in your hair before you enter the communal bath.

7. Enter the bath slowly: Step into the hot water carefully. Keep your small washcloth out of the bathwater; most bathers fold it and place it on top of their head or set it on the edge of the tub.

8. Dry off slightly before returning to the changing room: Use your small washcloth to wipe excess water off your body before stepping back onto the woven mats of the changing area to keep the floor dry for others.

Common Mistakes to Avoid

• Do not take photos inside: Photography is strictly prohibited inside the changing rooms and the bathing areas to protect the privacy of all guests. You are welcome to take photos of the building's spectacular exterior, but put your phone away once you cross the threshold.
• Do not wash your clothes: The washing stations are strictly for washing your body, not for doing laundry.
• Do not swim or splash: The bath is a place for quiet relaxation. Avoid splashing, swimming, or diving, especially because the bath floor features delicate artistic tile work.
• Avoid drinking alcohol beforehand: Hot baths increase your circulation. Bathing after consuming alcohol can cause dizziness or dehydration.
