1.Introduction

The purpose of this document is to provide guidance for Search, Autocomplete, Address Verification, POI Evaluation and Routing rating within the Japan market. As such, these guidelines should be considered supplemental to the Global Search, Autocomplete, Address Verification, POI Evaluation and Routing Guidelines.

2.Address Components in Rating Interface

.

*Use Sub-Locality Checkbox when present to report issues regarding Sub-Localities. If checkbox is not present, continue using “Country specific issue”.

3.Required Address Components

The table below outlines the required and optional address components for general result types. The rule applies to all Maps Evaluation tasks with some exceptions to Autocomplete.

 

4.Name Accuracy
4.1Incorrect Scripts
4.1.1. When Result Script is “Japanese”

The modern Japanese writing system uses a combination of scripts below:

Hiragana

ひらがな: Hiragana

カタカナ: Katakana 
漢字: Kanji (Chinese originated characters) 
ローマ字: Roma-ji (English/Latin alphabets) 

The expected scripts for POI names depend on what scripts are used in the official sources. Use of different scripts within POI names should be rated as following:

Name Rating

Explanation

Partially Correct

Result’s POI Name uses script that does not match the official website, but it is acceptable in Japanese writing system.

Incorrect

Result’s POI Name uses script that does not match the official website, but it is not acceptable in Japanese writing system.

.

English to Katakana conversions can be widely seen as business often have their signs in English but written and spoken in Katakana when referring to the business, rate Correct for such case.

On the other hand, Kanji to Hiragana or Katakana conversions may be difficult to decrypt depending on the length of the name, therefore considered as distracting to the user, rate Name Accuracy – Incorrect.

Result Name

Official Business Name(s)

Rating and Explanation

イゾラブル

(Isola blu) Katakana script

沖縄ワールド

(Okinawa world)

Kanji + Katakana script

おきなわワールド

(Hiragana + Katakana script)

Partially Correct

(Kanji script)

Incorrect

Official website uses Kanji script while result name uses Hiragana script. This is considered unacceptable by Japanese writing system and should be rated as Incorrect.

.

4.1.2Alternate Spelling for Kanji Characters

Kanji characters sometimes have alternate forms 異体字) and may not be straightforward to detect. Please use your local expertise to make a best judge.

For results that are in different Kanji forms such as Old Kanji (旧字体) or Simplified Chinese (簡体字) , apply the general rule whether the deviation is confusing or not, and rate: Partially Correct or Incorrect.

Result Name

Official Business Name s)

Rating and Explanation

横浜頂食堂

横濱頂食堂

Partially Correct

The business specifically uses instead of , but this variation is commonly seen in the locale.

壹番館

一番館

Incorrect

This is not commonly use alternate Kanji form, so it is highly possible that user will confuse and have a difficulty to understand the result.

4.1.3Foreign Scripts

In Japanese language it is common to use English/Latin alphabets, therefore minor deviations in Latin scripts are tolerated. Please use global guidelines for more details and examples.

 

4.2Missing Store Location

If store location name is missing from the POI name and branch name information presents at official resources, rate Name accuracy as Partially Correct.

Branch name provides the user a good idea of where the POI is without even looking at the address, this also prevents potential confusion when the services from one branch to another are significantly different even though they are under the same brand business.

5.2Result Address Expectation

This section is to provide a fundamental understanding for the different variations of Japanese address that appears differently in the rating interface.

See 5.2.1 Address types for how address results are expected to be formatted in the interface.

Simplified overview: majority of the Japan’s address components

.

5.2.1Address Types

5.2.1.1Cities – General Address System Display block-based)

Below is the address shown with 2 different ways to display block-based address type; the top example shows fully written suffixes for the numeric elements of the address Chome, Ban and Go), while the bottom example is written with the suffixes being abbreviated. Both are commonly accepted ways the address is displayed in Japan.

Address type

Example in Japanese

Example translated to English

Block based address:

Postal Code Prefecture City

Machi Aza (Sub locality + Chome) Block number House number

T 253-0041 Kanagawa-ken Chigasaki-shi

Chigasaki 1 Chome 1 ban 1 go

T 253-0041 Kanagawa-ken Chigasaki-shi

Chigasaki 1 1 1

5.2.1.2Cities – Chiban system land-ownership-based)

Like 5.2.1.1, the suffixes for numeric elements may be abbreviated and both forms are considered as correct.

Urban cities tend to display block-based address system in general, however, still many areas use Chiban address system. Reference to the branch number may or may not exist.

Address type

Example in Japanese

Example translated to English

Chiban (Land ownership):

Postal Code Prefecture City Machi Aza (Sub localities) Land number (Branch number)

Kouyama 478 2

 

5.2.1.3Towns and Villages

Towns and villages always fall under Gun ) within the relevant prefectures.

Compared to urban cities where block-based is a prevailing address system, towns and villages tend to use both systems Chiban and block-based) proportionally.

7.1.3Language / Script issues

If the result script is not matching the expected script the rating should be Incorrect with selected checkbox for Language/Script issue and the appropriate component s).

Though the expected script for the address will be Kanji in most cases, some localities/sub-localities have an official name as Hiragana or Katakana. In such case, the script of the result should reflect the official name.

Examples of Hiragana and Katakana script in place:

Hiragana Script

さいたま市 Saitama city) in Saitama prefecture

Katakana Script

ニセコ町 Niseko town) in Hokkaido
南アルプス市 Minami Alps city) in Yamanashi prefecture

 

1.3Address Research

Japanese address by nature is difficult to research, use online map providers and web search engines to verify address. Street imagery and photos of buildings may also be helpful, as cities are beginning to implement address tags on buildings which may be visible from the photos.

Generally, follow the research workflow in the global guidelines and consider an address correct if multiple sources agree, Can’t Verify if information is limited to confirm the confidence of sources and Incorrect if the address is identified as wrong/cannot exist.

1.3.1Address Research – Prominent providers and inability to find specific address

Even though major maps providers do not find the specific address, 19-11, Jinan 1-Chome, Shibuya-ku, Tokyo 東 京都渋谷区神南1-19-11), web search indicates that 3 businesses [BEAUTY & YOUTH UNITED ARROWS SHIBUYA KOENDORI, Crazy TV, IMAGICA Corp.] claims the address as shown in the following image.

In such cases, consider the specific address as valid where the business is located.

See 6.1.4.2 Query that address/territory does not exist for more information.

6.Search

For Search in Japan, the major rating challenges are identifying the relevance and prominence of the suggested results to the user.

Due to the nature of Japanese language, incomplete queries often have multiple matches that may be an exact match to the queries or phonetic matches in different scripts.

6.1Relevance
6.1.1Different scripts in Japanese

Japanese language uses 4 interchangeable scripts: Hiragana, Katakana, Kanji, and Roma-ji English alphabets).

Users type Hiragana first and then convert them to Kanji or other forms. Kanji is often the final script unless the business intentionally uses non-Kanji scripts as part of their marketing strategy or the word in a foreign derived word and using Katakana or Roma-ji.

Users often make a typo when converting words instead of leaving it in the designated form by the business, hence Search results should include both exact and phonetic matches across scripts.

When both exact and phonetic match results are present, decide which one or both could be the primary intent based on a query or location intent.

6.1.2Transformations

6.1.3.1The user has explicitly indicated so in the query
6.1.3.2The intersection itself is a highly prominent
6.1.3.3No more prominent or relevant results to return

Intersections with traffic lights often have the same or similar name as address and POIs in Japan. Instead of the intersection, suggesting the actual address and POIs are more useful, and it can confuse users to show the same name appear twice in the list with one being the intended result and another being the intersection.

6.1.3.2.Bus stops with similar names as POIs

Bus stops that have identical names as POIs and address should be rated 1 grade lower than those POIs and address. In other words, consider bus stops as secondary intent to queries that may be looking for a particular POI or address.

Bus stops in front of POIs often have the name of the POI + :mae means in front of-) or in some cases the bus stop name might be identical to the name of the POI or address.

(Honatsugi station) that has category as bus stops (バス停) with pin over the bus terminal.

Good

Even though the bus stop has an identical name as the train station, the primary intent is the train station. The bus stop with same name is secondary intent, therefore, receives a 1 grade lower.

[神奈川工科大学 (Kanagawa Institute of Technology)]

神奈川工科大学前

(Kanagawa Institute of Technology mae) that has category as bus stops (バス停) with pin correctly over the traffic signal.

Acceptable / Bad

Since user intent is clearly for Kanagawa Institute of Technology, bus stop at the same location with similar names is rated as Acceptable/Bad.

Users may refer to train stations without the word for station ), so it is often difficult to know whether the user is looking for a territory locality/sub-locality) or a train station that has the name of the territory.

When the query is ambiguous as to the same name for the train station and the locality, rate Excellent for both. If the query is clearly for the locality, then rate Up to Good for the train station.

川崎駅

(Kawasaki station) Pin drops at JR Kawasaki station.

Navigational / Excellent

Two Kawasaki station exist, one is for JR and the other is for Keikyu railways.

Especially when the query does not contain any additional words in front of Kawasaki station, the user is likely to search for a dominant JR Kawasaki station.

京急川崎駅

(Keikyu Kawasaki station)

Good / Excellent

Keikyu Kawasaki station is a Kawasaki station operated by Keikyu railways. Even though the station is not a dominant Kawasaki station, serving different line with the same location name around the JR Kawasaki station is likely to be user intent.

As JR Kawasaki station is used by nearly 30% more users than Keikyu Kawasaki station on daily bases, Keikyu Kawasaki station can be less likely to be user intent than JR Kawasaki station.

新川崎駅

(Shin Kawasaki station)

Bad

A station with similar name located far away from Kawasaki station is not user intent.

When an ambiguous term that could mean the territory or the train station i.e. 横浜) is used as a location modifier/intent for a query, such as “横浜 コンビニ” Yokohama convenience stores = “location + category”) and “川崎 ローソン” “location + chain), generally consider results near train stations to be the primary intent unless it makes sense for user to look for the particular category/chain inside a large area like the city, or if the territory is not a city and is small enough to serve as location intent. For example, it does not make much sense for user to look for all the convenience stores inside Yokohama City, which could be hundreds of matches and there is no clear reason/intent behind why people would want to know any random convenience store inside such large area. On the other hand, it would make more sense to look for airports or baseball stadiums inside a city than near a train station, since there are generally only few candidates inside a city and each of them have irreplaceable/unique values.

Example Query

Category Type

Rating and Explanation

[横浜 カラオケ (Kawasaki karaoke]

Small POIs without much unique value – i.e., user not willing to travel far for these POIs

Train station as primary location intent

Consider primary intent to be Karaoke stores near Yokohama station and rate results based on distance from the station. There is no clear reason why user would be interested in any random karaoke store inside a large area like the Yokohama City, so it is much more meaningful to return results near the station as it’s common for users to look for POIs near train stations.

[大阪 博物館 (Osaka museum)]

Touristic POIs with unique value – each POI cannot easily be replaced by another POI

Territory as primary location intent

For touristic POIs, the primary location intent would be in/near the territory (Osaka City in this case, not the prefecture), since each POI has unique value that user is willing to travel for. For instance, when user looks for “京都 観光地” (Kyoto tourist attractions), no one would really limit themselves to just the area near Kyoto station.

[みなとみらい セブンイ レブン

(Minatomirai 7 11)]

Small POIs without much unique value + small territory

Territory as primary location intent

When the territory in question is smaller than locality (city/town/village), then generally consider the territory as the location intent instead of the train station because 1) The query then has the exact name of the territory (みなとみらい is the exact name of the territory) and 2) the territory is much smaller than a city, so any random POI in the area would have similar value to the user.

.

More examples of small replaceable POIs (train stations as primary location intent when ambiguous) –

Restaurant, bar, café, convenience store, karaoke, bank/ATM, hotel, shops, parking lot, etc

More examples of POIs with unique value (territory as primary location intent when ambiguous)

Airports, stadiums, museums, shopping malls, zoo, tourist attractions, schools, etc.

Other stations in Tokyo are considered relevant to the user intent, but slightly less relevant than the station that is an exact match to the query.

6.1.4Address Queries

Address search in Japan is straightforward except when building name is involved.

Always rate the pin against the returned result.

6.1.4.1With or without building name in the query

Building names in Japan help point to unique locations, but they are not a critical component.

When building name is specified in the query, but not returned in the result or returned incorrect one, consider it as Data issue for missing building name. Relevance should be also considered when multiple buildings belong to the same house number.

If the query specifies single location returning the result that is unable to identify the location without building name information at the address, rate relevance as Acceptable.

When the query specifies single location by the building name returning the wrong building that belong to the same full address, rate relevance as Bad.

7.2Address Queries
7.2.1Residential Address

Japanese address system is formatted using higher level components first building towards lower component level, which makes it difficult to guess the exact address user is looking for. In general, rate each suggestion based on distance from the user / viewport, prominence, and availability of other possibilities.

For instance, please take the difference in address level of the suggestion into consideration and that of the query; if query only shows the prefecture, then a suggestion for a sub-locality and beyond may seem random, unless it is a prominent sub-locality, because the user has not specified the city yet.

For the same reason, suggestion into the numeric components of the address are generally considered not helpful for the user because it is extremely unlikely that we can guess the exact number the user is looking for unless the user have typed a number for the house number ).

1.2Case Study: Valid / Impossible to Distinguish between Multiple Rooftops

If an address is as specific as possible in real world, then please consider the address ” Valid” even if there may be multiple rooftops sharing the same address.

Sometimes an address may be shared among multiple rooftops that do not have building names in real world, often applying, but are not limited, to residential addresses and rural businesses. In such case where the Query Address is as full as there can be (i.e. no building name, no further branch number (枝番) beyond house number, nothing in real world that could be added to the address to make it “valid”), please rate Valid for query address and treat it the same as BUSINESS WITH MULTIPLE ROOFTOPS AT SAME ADDRESS where any rooftop would be perfect.

1.3Case Study: Valid / Address Based on Frontage System

Even if you cannot verify the existence/use of an address, please consider the address ” Valid” if both of the following conditions are met:

1)The address belongs to 住居表示実施地区 that uses フロンテージ (frontage system) for addressing
2)The door number () for the address falls within range of possible door numbers for the block.

In urban areas of Japan, addressing are standardized based on frontage system (住居表示) where door numbers are assigned based on which 10~15 m segment a business/building’s main entrance falls within. (See diagram below from official website of Abiko City in Chiba)

In the diagram, 8 in dark circle would be the ban and the numbers on the upper right corner of each building are the go (door numbers). For example, the address for the building named “共同住宅” at lower left corner would be 8 13 (8番 13号).

If query address is looking for 8 9(8番9号) from above diagram, we would consider it Valid even if there is no building currently assigned to it because 1) The block 8is using a frontage address system, and 2) we know that 8 8 and 8 10 exist as there are buildings assigned the addresses, so it can be assumed that 8 9 exists between 8 8 and 8 10

The result address and pin accuracy would then be rated according to global guideline. For pin, consider applying the empty plot rule if you cannot confirm a building exists for 8 9 (i.e. either the plot is empty or if there is a building but that building is confirmed to have a different door number like in the case above where the building located at the frontage of 8 9 is given the address 8 8 due to the position of the entrance).

9.POI Evaluation
9.1POI Validity

The POI Validity of businesses/POI may be questionable due to various business forms in Japan. If not enough resources verify the existence of the business, do not hesitate to select the POI Validity as Can’t Verify in POI Evaluation.

Here are a few examples to guide you POI Validity

Query

Query Type

POI Validity and Explanation

勝川IC

(Kachigawa Interchange)

Interchange

Valid

Interchange is mainly the entrance and exit of highways, expressways, which matches the definition in the guideline of “POIs are places that users would want to find on a map and potentially navigate to.” Hence, the POI Validity is Valid.

 

10.Pedestrian Routing
10.1Pedestrian Overpass

.

If polygon in the vector map indicates the presence of pedestrian overpasses or footbridge,^

rate Acceptable if both of the following are true:

1)The navigation line obviously does not follow the polygon for the pedestrian overpass
2)The pedestrian overpass is the only way to cross the road at that location.

In other words, if we have pedestrian overpasses in the base map, we should be using it when there is no other option.
