Searching for addresses in Japan can be a daunting task, especially for those who don't speak the language. You can use online tools to search for addresses in Japanese, such as Google Maps or Japanese address search websites.
In Japan, addresses are typically written in a combination of kanji and Romanji, making it difficult for non-Japanese speakers to read and understand. For example, the address "1-1-1 Shinjuku-ku Tokyo" uses a combination of numbers and kanji characters.
To make Japanese address search easier, you can use online translation tools to help you decipher the address. Many websites and apps offer translation services that can help you understand the address in English.
Using a Japanese address search website can also help you find the correct address, even if you don't speak Japanese. These websites often have a database of addresses that you can search through.
Japan Postal System
The Japan Postal System is unique in its approach to addressing.

In Japan, named street names are scarce, only appearing in Kyoto and Sapporo.
The system prioritizes identifying different areas over naming streets.
Addresses in Japan are structured from largest land mass to smallest.
This hierarchy is essential for navigating Japan's postal system.
You'll find that addresses in Japan are often more about identifying regions than pinpointing exact locations.
Address Structure
A Japanese address is structured in a way that's quite different from what we're used to in the West. In Japan, addresses start with the postal code, followed by the largest geographic element, and finish with the smallest-most specific element, such as the apartment or room number.
The largest geographic element is usually the prefecture or city, which is followed by the ward or county. For example, in the address 東京都世田谷区北沢2-13-4, "東京都" refers to Tokyo Prefecture, and "世田谷区" refers to Setagaya Ward.
Here's a breakdown of the typical components of a Japanese address:
- Municipality (city/ward/county): This is the largest geographic element and includes the name of the city, ward, or county.
- Town/Village: Some addresses are further divided into smaller geographical elements, such as towns or villages.
For example, the address 神奈川県横浜市中区桜木町 can be broken down as follows: Kanagawa Prefecture, Yokohama City, Naka Ward, Sakuragi Town.
Municipality (City/Ward/County)

A Japanese address can be quite different from what you're used to in the West. In Japan, addresses start with the postal code, followed by the largest geographic element, and finish with the smallest-most specific element, in other words, the apartment or room number.
The largest geographic element in a Japanese address is often the city, ward, or county. For example, Tokyo is divided into 23 special wards (特別区, tokubetsu-ku), commonly referred to as just wards (区, ku).
You'll see the name of a city followed by the suffix (市), like Yokohama city (横浜市, Yokohama-shi). Bigger cities can be divided into smaller sections, which are also called wards. For instance, Shinjuku ward (新宿区, Shinjuku-ku) is a ward in Tokyo.
Smaller geographical areas, less populated than cities, are called counties or districts (郡, gun). A county is often found in rural addresses in Japan.
City Block
The city block is a crucial part of a Japanese address, and it's often irregular in shape and can be located in a scattered order. This is because they are numbered after the order they were registered.

The city block number, or banchi, is preceded by a number and comes after the city district. For example, as seen in Example 3, the city block number is often preceded by the number, like 3-3-13-502.
In some cases, the city block number can be a bit tricky to spot, especially if it's not labeled clearly. However, if you notice that the blocks are generally in some sort of pattern, it can make it easier to find the correct block.
Here's a breakdown of how to read a city block number:
- City district
- City block number (preceded by a number)
- House number (or building name)
For example, in Example 2, the city block number is 2-13-4, which means the block is 13, and the house number is 4.

Writing and Reading Addresses
Writing a Japanese address can be a bit tricky, but it's actually quite logical once you get the hang of it. You start with the postal code, followed by the largest geographic element, and finish with the smallest, most specific element.

In Japan, you won't typically see a street name in an address, which is different from what you're used to in the West. Kyoto and Sapporo are exceptions to this rule, but for most of the country, it's a different system.
To write an address in rōmaji, the Roman alphabet, you start with the apartment or building name and finish with the prefecture and postal code. This is the opposite order of how you would write it in Japanese characters.
For example, the address to the Go! Go! Nihon office is written as 3-13-3 3F Seiwa Ikebukuro building, Higashi-Ikebukuro, Toshima-ku, Tokyo-to 170-0013 in rōmaji.

Writing in Romaji
Writing in Romaji can be a bit tricky, but it's actually quite straightforward once you get the hang of it. The order of writing is reversed compared to Japanese characters, so you start with the apartment or building name and finish with the prefecture and postal code.

For example, the address to the Go! Go! Nihon office in Romaji is: 3-13-3 3F Seiwa Ikebukuro building, Higashi-Ikebukuro, Toshima-ku, Tokyo-to 170-0013.
Here's a breakdown of a Romaji address:
- Start with the name of the residence
- Followed by the block, building, and ward numbers
- Then the name of the ward
- Then the city or metropolis
- Then the prefecture
- And finally the postal code
It's worth noting that the Romaji address is different from the Kanji address, which starts with the postal code and then lists the prefecture, city, ward, district, block, and number.
Here's a simple table to illustrate the difference:
Reading Addresses
In Japan, addresses are often more about landmarks than actual house numbers. Instead of using addresses, it's common to find someone's house by recognizing familiar landmarks.
You can easily get lost in Japan's winding streets, but that's also part of the adventure. Finding your way by landmarks is a great way to discover new areas.
Using landmarks to find someone's house is the easiest way, especially in Japan. It's a fun and unique way to explore a new place.
Don't be afraid to open the door and take a chance – it's all part of the experience.

Address Search and API

To use the Jageocoder API, you'll need to import the jageocoder library and initialize it with the init() function. This function takes two optional parameters: db_dir and url.
The db_dir parameter specifies the directory where the address database is installed, while the url parameter specifies the endpoint URL of the Jageocoder server. If you omit the url parameter, the API will use the value of the environment variable instead.
To get started with Jageocoder, you can simply import the library and initialize it with the default settings, relying on the environment variable to provide the necessary information.
Addresses
In Japan, addresses are structured differently from what we're used to in the West.
Addresses start with the postal code, which consists of 7 digits, preceded by the symbol "〒". This is a unique identifier for each location.
The Kanji address always starts with the postal code, followed by the prefecture, city, ward, district, block, and number, in that order. This is a standard format used throughout Japan.

In contrast, the Romaji address starts with the name of the residence, block, building, and ward numbers, followed by the name of the ward, city or metropolis, prefecture, and postal code.
Here's a breakdown of the administrative division of Japan:
Japan is divided into 8 geographic regions, each with a specific number of prefectures: Kyushu (8), Shikoku (4), Chugoku (5), Kansai (7), Chubu (9), Kanto (7), Tohoku (6), and Hokkaido (1).
Jageocoder - Python Geocoder
Jageocoder is a Python port of the Japanese-address geocoder DAMS used in CSIS at the University of Tokyo's "Address Matching Service".
It's a powerful tool for geocoding Japanese addresses.
This geocoder is used in the University of Tokyo's "Address Matching Service" and GSI Maps.
Jageocoder provides accurate and reliable geocoding results for Japanese addresses.
It's a valuable resource for anyone working with Japanese address data.

Connect to Jageocoder Server
Connecting to a Jageocoder server is a great way to perform address searches without installing a dictionary database on your machine. This approach saves storage space and reduces the time and effort required to update the database.

You can connect to the Jageocoder server by specifying the server endpoint in the environment variable JAGEOCODER_SERVER_URL. For a public demonstration server, use the endpoint provided in the documentation.
However, keep in mind that the public demonstration server has a limit of one request per second to prevent overload. If you need to process a large number of requests, you'll need to set up your own Jageocoder server, which can be done by following the instructions provided in the documentation.
Using API
To get started with the API, you'll need to import the jageocoder and initialize it with init(). You can specify the directory where the address database is installed by using the parameter db_dir.
The parameter db_dir is used to specify the directory where the address database is installed. This allows you to store the database locally on your machine.
Alternatively, you can specify the endpoint URL of the Jageocoder server with the url parameter. If you omit this parameter, the value of the environment variable will be used.
Navigating Address Issues

In Japan, addresses can be a puzzle to decipher, especially for foreigners.
Addresses in Japan typically consist of a combination of numbers and letters, which can be confusing to read and write.
The Japanese address system uses a unique format, often including multiple lines of text, including the building name, floor number, and apartment number.
To make matters more complicated, some addresses may use a combination of kanji and romaji characters.
The best way to navigate address issues is to use online tools, such as the Japan Post website, which can help you search and verify addresses.
With the help of technology, you can easily search and verify addresses in Japan, saving you time and effort in the long run.
