1. What is a Sento? Basic Knowledge You Should Know First
What is a Sento?
A Sento is a traditional Japanese public bathhouse where local people gather to relax and rejuvenate both body and mind.
Developed during the Edo period, there were over 18,000 Sentos nationwide during the Showa era. Although the number has decreased due to the spread of home baths, Sentos are once again gaining attention as places where you can enjoy a retro atmosphere and warm community interactions.
• "Experience the luxury of soaking in a large bath."
• "Feel the warmth of the community with close interactions."
These are the charms of a Sento.
Sentos are also becoming increasingly popular among foreign tourists as spots where they can experience Japanese culture firsthand.
2. Things to Know Before Going to a Sento
① Necessary Items
Convenient Items to Bring:

• Coins (for the bath fee & lockers)
Items Not Allowed:
• Swimsuits (Sentos are for bathing naked)

Japanese Sentos have specific bathing rules, so even first-timers can enjoy the experience with confidence. Here’s a step-by-step guide!
① Reception (Bandai or Front Desk)
• Pay the bathing fee at the bandai or front desk

• Put your shoes in the shoe locker
• Take off your shoes at the entrance and place them in a locker (keep the key if there is one).

Points to check before bathing:
• Bathing naked is the norm (swimsuits are not allowed).
• Take one towel with you to the bath area.
• Tie long hair with a hair tie (to prevent hair from soaking in the water).
③ Entering the Bath Area & Washing Your Body
Perform "kakeyu" (pouring hot water over yourself):
