Japan's four countries are a place for quiet vacations. There is no big industry, no excessive noise, soak in hot springs, take a leisure look at the most traditional culture, eat and drink. Matsuyama City, nearly 400 years of history, is an important cultural property of Japan, one of the twelve days of guardianship. After vicissitudes of life, the city is still in high spirits. Silver tiles shine in the summer sun, the wooden structure is upright and strong, and the room is spotless. The armor and weapons displayed in the display cabinet tell us about the historical changes and the change of rights. Datianshu is on the top floor, 360 degree view of Songshan City, overlooking the Inland Sea of Seto. The tram in Songshan downtown gets off at Dajie Station, walks along the sign to Songshan City Cable Station, and buys tickets to go up the mountain. Tickets have different prices. We bought a 1,020 yen ticket for one person, including a lift and a sightseeing ticket.
