Mamiya is asteroid #12127 and is also known as 1999 RD₃₇. Mamiya was discovered by the Japanese amateur astronomer Watanabe Kazurō (渡辺 和郎) at the JCPM Sapporo Station. Mamiya’s orbit is characterized by a semi-major axis of 2.45 Astronomical Units, an eccentricity of 0.19, a period of revolution of 1 403 days, and an inclination of 3.6 degrees. Mamiya belongs to the Nysa-Polana-complex.

Mamiya is named after Mamiya Rinzō (間宮 林蔵). He was a Japanese sailor, explorer, cartographer, and surveyor of the northern are of Japan. He lived on the material plane from approximately 1775 (to 1780) until 1844, 13th of April. Mamiya Rinzō (間宮 林蔵) was a student of the Japanese cartographer Inō Tadataka (伊能 忠敬), who lived from from 1745 until 1818 and became known for the first map of Japan based on measurements. Then Mamiya Rinzō (間宮 林蔵) worked from 1800 on for the Shōgun (将軍) as a land surveyor of Ezo (蝦夷). He got wounded in a Russian assault on Iturup, one of the Kuril Islands, in 1807. Then Mamiya Rinzō (間宮 林蔵) was ordered to explore Karafuto (樺太). This is what is known as the island Sakhalin, but also was a province on this island because parts of this island were inhabited by Japanese. Although Japan had claimed this island as Japanese territory, it is Russian now. The Japanese had thought that Karafuto (樺太) would be part of the Asian mainland. Mamiya Rinzō (間宮 林蔵) explored the eastern coast of Sakhalin in 1808 and the western coast in 1809. He found that Sakhalin is an island separated from the mainland by a channel, which now is called the Mamiya Strait. He decided to explore the mainland too and ended the exploration at the riverside place, where now is the Russian city Komsomolsk-na-Amure (Комсомо́льск-на-Аму́ре). Mamiya Rinzō (間宮 林蔵) described the areas and people of the regions, which he explored, in the two reports Kita Ezo zusetsu (北蝦夷図説) and Tōdatsu chihō kikō (東韃地方紀行).

Mamiya Rinzō (間宮 林蔵) later worked as a spy for the Shōgun (将軍). Hence a role of Mamiya Rinzō (間宮 林蔵) in the arrest of Takahashi Kageyasu (高橋 景保) is presumed. Takahashi Kageyasu (高橋 景保) was a geographer and a scholar of Western Studies. He was found guilty of secretly exchanging maps with the German researcher Philipp Franz von Siebold. Takahashi Kageyasu (高橋 景保) died while he was in jail waiting for his trial. Mamiya Rinzō (間宮 林蔵) was lonely at the end of his life and none of his colleagues wanted any contact with him. Until 2002 was believed that Mamiya Rinzō (間宮 林蔵) died childless. But in 2002 was announced that he had a daughter with an Ainu woman and their descendants were living in Hokkaidō (北海道).

Japanese names use to be translatable. But not literal in this case. The name of the asteroid #12127 is Mamiya (間宮). This is the family-name of Mamiya Rinzō (間宮 林蔵), who also had the name Mamiya Tomomune (間宮 倫宗). The latter seems to have been his real name. I didn’t figure out why he was called Rinzō (林蔵), although he was named Tomomune (倫宗). Both are male personal names. The latter reflects the parents’ wish to educate a righteous man, the former can describe somebody as hidden or as educated. But the important name here is Mamiya (間宮). The part miya (宮) means palace. It can describe a member of a royal or imperial family or instead an official or a servant working in a palace. Ma (間) has different pronunciations and then also different meanings, but most of them in the pronunciation ma (間). It means rooms, is a counting unit for rooms, also is a measurement unit for the size of rooms, denotes the space between two pillars of a house, means the space between two things, also means the time between two events as well as a pause in speaking in a theater play as well as a pause in a music play as well as free time as well as a good opportunity, and furthermore means an anchorage ground. So Mamiya (間宮) most likely is a family-name, that was derived from a profession. Mamiya (間宮) would then denote people, who are descendants of servants, who were janitors and room cleaners and alike in a palace. “Palace servant [in charge] of the rooms” should be as precise as possible for translating Mamiya (間宮) into English.

That Mamiya Tomomune (間宮 倫宗) passed away in loneliness tells me, as a German, a lot. The German Democratic Republic had a secret police known as the Stasi (this is short for Staatssicherheit or in translation state security) and many people spied on other citizens for this institution. This could be in the workplace, in a pub, in school, or even at home. Everywhere could be a spy of the Stasi. After the German Democratic Republic fell, the Stasi files were made public and many people learnt who had spied on them. After that many people avoided any contact to those spies. Mamiya Tomomune (間宮 倫宗) became a little bit famous under the name Mamiya Rinzō (間宮 林蔵) and for exploring Sakhalin. But what he did then seems to be the same as the Stasi agents did. This is the most likely reason why his colleagues avoided any contact with him and this most likely began after the arrest of Takahashi Kageyasu (高橋 景保). So the astrological force Mamiya most likely is the celestial representative of secret police agents.
