Onsen: A Must-Try Japanese Tradition
Onsen (温泉/natural hot springs) are one of the most iconic experiences in Japan. With over 27,000 hot spring sources across the country, onsen are an essential part of Japanese culture. For Indonesian Muslims, there are some special considerations, but that doesn't mean you can't enjoy them.
Considerations for Muslims
Some Sharia-related considerations often asked by Indonesian Muslims:
- Aurat (Modesty): Traditional onsen are indeed nude. However, there are alternatives (see below).
- Gender separation: Onsen are ALWAYS separated for men and women (except for rare mixed/konyoku baths).
- Clean water: Onsen water is constantly flowing and is changed regularly. You are also required to wash your body thoroughly before entering the tub.
- No alcohol in the bathing area: Alcohol is consumed separately, in the rest area.
Alternatives for Those Uncomfortable with Nudity
1. Kashikiri Onsen (貸切温泉) - Private Onsen
- Rent a private onsen room for yourself or your family
- Price: 2,000-5,000 yen per 30-60 minutes
- Available at many ryokan and onsen resorts
- The best recommendation for Muslims
2. Ryokan with In-Room Onsen
- Some ryokan (traditional inns) have a private onsen inside the room
- Price: 15,000-50,000 yen per night (including meals)
- You can bathe anytime without meeting other people
3. Ashiyu (足湯) - Foot Bath
- Only soaking your feet in hot water
- FREE in many onsen areas like Hakone, Beppu, Kusatsu
- No need to undress, just sit on the edge and dip your feet
- Very suitable for everyone, including those who are shy about bathing
4. Konyoku with Yuami-gi
Some modern onsen provide yuami-gi (special onsen wear) that can be worn while bathing. This is becoming popular, especially in large resorts.
Onsen Etiquette You Must Follow
- Wash your body BEFORE entering the tub - This is the most important rule. Sit on the small stool in the shower area, soap your entire body, and rinse thoroughly.
- Do not bring towels into the tub - The small towel can be placed on your head or on the edge of the tub.
- Do not swim or play in the water - Onsen are for quiet soaking and relaxation.
- Tie up long hair - Hair should not touch the tub water.
- Do not dip your head - Only your body should go into the water.
- Enter slowly - The water can be very hot (40-44 degrees Celsius).
- Do not soak for too long - 15-20 minutes per session is enough. Get out if you feel dizzy.
The Tattoo Issue
Many onsen in Japan PROHIBIT guests with tattoos due to their association with the yakuza. If you have a tattoo:
- Look for "Tattoo OK" onsen - Use tattoo-friendly.jp to search
- Small tattoos: Some onsen allow them if covered with a special patch (sold at the onsen)
- Private onsen: Always possible, as no one else is there

Sento vs Onsen
| Aspect | Onsen | Sento (銭湯) |
|---|---|---|
| Water source | Natural (volcanic) | Heated (tap water) |
| Location | Mountain/rural areas | In the city, near homes |
| Price | 500-2,000 yen | 500-520 yen (regulated) |
| Facilities | Resorts, ryokan, restaurants | Minimalist, local |
Sento are a cheap, daily alternative. Many are in big cities and the etiquette is the same as for onsen. Suitable for Indonesians who want to try a hot bath without leaving the city.
Tips for Beginners
- Bring your own towel or rent one at the onsen (usually 200-300 yen)
- Drink water before and after bathing to prevent dehydration
- Do not bathe when drunk or immediately after eating
- Try ashiyu first if you have never been to an onsen at all
Onsen is one of the pleasures of life in Japan that is a shame to miss. With options like private onsen and ashiyu, Indonesian Muslims can also enjoy this tradition comfortably. Try it at least once during your stay in Japan!
