Japan has one of the best postal services in the world.
The approximately 24,000 post offices provide a range of postal services including the shipping of letters, parcels, post cards, postal orders and registered mail as well as banking and insurance services.
Small post offices are open from 09:00 to 17:00 Monday to Friday, and are normally closed on weekends and national holidays.
However, larger post offices may stay open until 19:00 on weekdays and open for restricted times on weekends.
Today, more and more elderly people or people with disability are traveling in Japan.
Japan has put into force a law to ensure accessibility at many places throughout the country. Organizations at different levels such as the Japanese government, local authorities and NPOs have worked on the development of an accessible travel environment for everyone including people with disabilities and special needs.
Ryokan "旅館" are traditional Japanese inns, and a visit to one is the highlight of many, a trip to Japan.
They can be found throughout the country, especially around tourist areas such as hot spring resorts, ski resorts and in mountains.
There are two types of Ryokan; the small traditional-style one with wooden buildings, long verandas, and gardens, and the more modern high-rise sort that are like luxury hotels with fancy public baths.
Since some knowledge of Japanese mores and etiquette is required to visit one, many hesitate to take non-Japanese guests especially those who don't speak Japanese, but some cater specially to this group.
