About an Ancient Tomb in Kamakura, Japan

Kamakura is an ancient capital from about 1000 years ago. There are many beautiful temples and gardens, making it a famous spots for sightseeing, other than Nara and Kyoto in Japan. What is the specific attractiveness of Kamakura that the other places don't have? I think it is an atmosphere that comes from the unique geology that is mainly composed of tuff. Tuff is a kind of stone that is soft and easy to process, therefore ancient people made many caves and tunnels in Kamakura. Ancient people often used the caves of tuff as tombs. Kamakura is a narrow place enclosed by mountains on three sides and sea on the other side. Therefore the people of Kamakura were believed not to be able to make usual tombs on flat land, instead, they made tombs in the tuff wall outside of the city. The tombs are in caves called "Yagura", and you can still see Yagura everywhere in Kamakura. For example, Mandara Yagura-do is one of the biggest aggregation of Yagura. This place is not always opened, but from 10 am to 4 pm every Saturday and Sunday (and also Monday if it is a public holiday) during a decided term it is. The next term is from October 19th to December 15th in 2019. The term and other detailed information are announced in HP of Zushi city of Kanagawa prefecture, and there are English pages in https://www.city.zushi.kanagawa.jp/global-image/units/125114/1-20181015105034.pdf.

There's no entry fee, but a donation may be recommended for maintenance of the heritage. Besides this Mandara Yagura-do, you can see many Yagura along hiking course around Kamakura.
