(Blue Mountain, Green Mountain)
Today, Aoyama is one of Tōkyō’s most fashionable and expensive neighborhoods. It borders Harajuku and Shibuya and is famous for shopping, high end dining and has a remarkable amount of green space – sorely lacking in other areas of the city.
The word is made of two characters:
青 ao blue or green (depending on who you ask)
山 yama mountain
Aoyama is a family name.
In the Edo Period, 郡上藩 Gujō-han Gujō Domain (located in 美濃国 Mino no kuni Mino Province; modern day 岐阜県 Gifu-ken Gifu Prefecture) was administered by the Gujō branch of the Aoyama clan. The castle and seat of the domainal government was at 八幡城 Hachiman-jō Hachiman Castle, so sometimes the domain is referred to as Hachiman-han. Since the clan originated in Mikawa, the family had a special relationship with the Tokugawa. At one point, during the Sengoku Era, they were responsible for the education of Tokugawa Hidetada who would later become the second shōgun.
They had a sprawling palatial residence (下屋敷 shimoyashiki) in the outskirts of Edo. When daimyō residences were confiscated by the Meiji government for re-purposing, the land of the Aoyama residence was converted into present day Aoyama cemetery. It’s a massive urban cemetery. If you walk around it, you can get a feel for how large the estate once was. Even though the family was only worth 48,000 koku, this sub-residence was one of the biggest in all of Edo. None of the domain’s buildings exist today, but the Aoyama family temple, 梅窓院 Baisō-in Baisō Temple, can still be found in Minami Aoyama.
