In Japan, bathing is not about getting clean. You get clean before you enter the bath. The bath itself is for relaxation, contemplation, and — in the case of hot springs — healing. This distinction is fundamental to understanding Japanese bath culture, a tradition that has survived for over 1,000 years.

Three Types of Japanese Baths

Onsen (温泉) — Natural Hot Springs

Sento (銭湯) — Public Bathhouses

Super Sento (スーパー銭湯) — Modern Bathing Complexes

How to Bathe (The Complete Process)

Step 1: At the Entrance

Step 2: The Changing Room (脱衣所)

Step 3: Wash First (重要!)

Step 4: Enter the Bath

Step 5: Repeat (Optional)

Step 6: After Bathing

Tattoo Policy

The Uncomfortable Truth

Many onsen and sento prohibit tattoos. This is because tattoos are historically associated with yakuza (Japanese organized crime) in Japan. The ban is cultural, not personal — it applies to Japanese people with tattoos too.

Your Options

  1. Private onsen/rotenburo — Book a room with a private bath at a ryokan. No rules apply
  2. Tattoo-OK facilities — Increasing in number, especially in tourist areas. Search “tattoo friendly onsen” + your destination
  3. Cover with bandages — Some facilities allow small tattoos covered with skin-colored bandages (waterproof types available at drugstores)
  4. Ask first — Some places are flexible, especially for foreign tourists. Call ahead
  5. Konyoku (mixed) or family baths — Private-use baths that can be reserved for your group

Sento Culture — The Neighborhood Bath

Why Visit a Sento?

While onsen are dramatic and destination-worthy, sento are the everyday version — the neighborhood bathhouse where regular Japanese people have bathed for generations.

What makes sento special:

The Philosophy

Japanese bathing culture reflects core Japanese values:

This is why Japanese people bathe every day — not just for cleanliness, but for the daily ritual of returning to yourself. Try it. After one soak in a rotenburo overlooking mountains, watching steam rise into cold air, you will understand why this tradition has endured for a millennium.
