Guide to Reading Tokyo Place Names: By the Numbers

This is part two of a multipart guide to reading Japanese place names. Here we’ll cover how numbers are used in place names with examples from around Tokyo and other parts of Japan. The examples given below are by no means exhaustive!

Part 1, which covers directions and geographic relationships, is here: Guide to Reading Japanese Place Names: With Kanji and Examples


Numbers, of course, very often appear in place and street names, just as they do in many languages.

Kanji (Chinese characters) also have multiple readings depending on the context or compound in which they are used.

The chart below summarizes the different ways that number kanji can be read.

二重橋 (Nijyu Bashi): “Double Layer Bridge”. Usually written as Nijubashi, this is the official bridge leading to the entrance of the Imperial Palace in Tokyo. It is only open on important state occasions. There is a second bridge behind this one, which used to be wooden bridge with two levels, which explains the origin of the name.

五 Itsutsu or Go: Five

五反田 (Gotanda): Literally “A rice paddy of about 5,000-sqm”. A busy neighborhood in Tokyo’s Shinagawa Ward. It is located between Meguro and Osaki on the Yamanote line. The name comes from the Edo period when a section of rice paddies formed a valley in the area that was measured to be about 5 “tan” (equal to about 5,000-sqm).

The name Hatchōbori comes from the Edo period when a moat dug in the area was measured to be 8 町 (read “chō”) long (町 means “town” and is read machi or chō, but it also means “a unit of length that measures about 109 meters”. Originally, Hatchōbori was written 八町堀 but the middle kanji was eventually changed to 丁 which is also read chō, but which has fewer strokes and is simpler to write.

十 Tō or Jyu: Ten

麻布十番 (Azabu Juban): Literally “hemp cloth number 10”. The first two kanji mean “hemp cloth”. Wikipedia (Japanese) tells us that it’s not clear exactly where “number 10” derives from. There are two possibilities: that it was the 10th area of the river that was refurbished or that it was the 10th area to be settled.

Azabu Juban, today is a an upscale residential area that is home to many foreign embassies, but the neighborhood has a relaxed and fun atmosphere with many affordable eateries.

百  Hyaku: One Hundred

百人町 (Hyaku Nin Chō): Literally “One hundred person town”. Hyakunincho is a neighborhood in Shinjuku Ward, Tokyo north of Shinjuku Station and west of Okubo.

The name of this neighborhood derives from the Edo period when there was a garrison housing the “Iga Hundred Gun Corps” led by Naito Kiyonari (an important retainer of Tokugawa Ieyasu) located in the area. These one hundred men protected the streets in the area and eventually it was named after them.

Naito Kiyonari was also the feudal lord whose land eventually became the area which we today know as Shinjuku. Read about the history of Shinjuku here: Shinjuku Then and Now.

The area around Hyakunincho and Okubo are known as Tokyo’s Korea Town. It is a cosmopolitan neighborhood with many excellent budget restaurants.

千 Chi or Sen or Zen: One Thousand

千鳥ヶ淵 (Chidorigafuchi): Literally “Chasm deep in plovers”. Chidori is Japanese for “wading birds” and “fuchi” means a chasm or deep pool. Chidorigafuchi is a moat located in the northwest of the Imperial Palace. It is said the name comes from the moat’s shape, which resembles plovers.

千駄ヶ谷 (Sendagaya): Literally “Valley where there is a lot”.

One of the explanations of the origin of Sendagaya’s name is that Ota Dokan, a 15th-century samurai warrior-poet was patrolling through the area and looked down into the valley where there was an abundance of rice growing. The area was named after this observation!

As Shibuya Ward’s official site explains 駄 means “the amount that can be carried by one horse”.

千駄 means “That’s a lot”. 谷 means “valley”. So the whole name literally means “valley where there is a lot” (of rice!).

Sendgaya is located in Shibuya Ward between Shinjuku and Shibuya.
