Japan tagging

Jump to navigation Jump to search

Japan tagging is a guideline for tagging Japan-specific features. See Map Features for common features not explained below. See also Japan for basic information. JA:Naming sample and JA:Howto Map A will be also the reference for examples of tagging.

Unlike general articles, the Japanese version is the original for Japan tagging. If you want to change the guideline, please ask on talk-ja mailing list.

Highway

Road types

In Japan, there are pre-defined tags for each element -- these are listed in the "Implies" column. If a road does not match that column, tweak the relevant tags.

Key Value Element Comment Example Typical image Useful combination Implies
highway motorway way Expressways or motor roads. If you see a sign drawn a white car in blue background: Japanese Road sign (Vehicles Only).svg at the entrance, it must be motorway. Most of motorways in Japan are toll roads. If it is toll-free, please tag toll=no.

highway trunk way National highways excluding expressways and motorways. Usually, National highways have blue triangle shield signs: Japanese National Route Sign 0001.svg.

Note that a little part of Japanese National highways have regions which cannot be accessed by motor vehicles, for example, steps, a pedestrian, a hiking way, or a ferry route. Those region should be tagged by other highway tags and add it to Relation:route with route=road and ref=number.

If you see a hexagonal shield sign, Nara Pref Route No.44 Sign.svg on the road and the number is one or two digits long, it must be this type. In addition to that, prefectural roads in Tokyo with three-digit number starting with 3 or 4 should be tagged as this type (Number 3xx and 4xx).

A region of expressway, motorway or road that cannot be accessed by motor vehicles should be tagged using other highway tags and added to Relation:route with route=road and ref=number.

Usage Example Notes
name=Japanese (English)
  • name=首都高速道路
  • name=桜田通り;国道1号
  • name=梅ケ枝通り;愛知県道145号富田一宮線
  • 2013年9月以降は,name で括弧併記(括弧内にローマ字または英語で name を記載する)は行わない方針としました.
  • 2013年9月以前の name では,括弧併記が用いられているものもあります.これらは無理して修正する必要はありません.また,括弧併記でローマ字を記載していることで,海外の方には利便性が増している事も忘れないで下さい.
  • 括弧併記を行わないことにした議論の過程は,https://lists.openstreetmap.org/pipermail/talk-ja/2013-September/007600.html から始まる一連のスレッドを参照して下さい.
  • 道路名が複数ある場合は、通りの名前を記述し、それ以外は loc_name(地元での名前),old_name(歴史的な名前)等のタグに該当する名前がある場合は別のタグとして記述し、当てはまらないものを alt_name(別名)で記述してください。
name:en=English or romanization of Japanese
  • name:en=Metropolitan Expressway
  • name:en=Sakurada-dori;National Route 1
  • name:en=Umegae-dori;Aichi Prefectural Road 145 Tomita Ichinomiya line
Although it is a common practice by some taggers to add english in parenthesis after the Japanese in the name=* field, the only place English should be added is in this field. Other taggers will delete English in parenthesis added into name=* . Bilingual support in OSM renderings is being discussed, and proper use of the name:*= tag will ensure it's correct operation in the future.

Places

Usage of place=* for Japan tagging.

Key Value Element Description Relation to admin_level Notes
place country node A nation. admin_level=2 Japan. node 424313451
place state node area A state. admin_level=3 Not currently used in Japan. This tag is reserved for a state when state system is enforced.
place region node A region.

The eight regions (Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chugoku, Shikoku, Kyushu). They are not official administrative units.

place province node area A prefecture. admin_level=4 The 47 prefectures. There are 1 都 (To), 1 道 (), 2 府 (Fu), and 43 県 (Ken) as prefectures.
place subprovince node area A subprefecture of Hokkaido. admin_level=5 There are 9 総合振興局 and 5 振興局 as subprefectures in Hokkaido.
place county node area A county (郡, gun) in a prefecture. admin_level=6
place city node area A city (市, shi) or a special ward (the "twenty-three wards" of Tokyo). admin_level=7

Neighbourhood place names

This section explains place name formats for below tags.

This section refers to 大字 as "quarter name" and 小字 as "neighbourhood name."

Chome contained in Place Name

Place names like「八幡一丁目」(Hachiman 1-Chome) often occur when the chome is the town name itself. Therefore, attach the tags place=neighbourhood+name=八幡一丁目. It is incorrect to interpret the town name as 八幡 (Hachiman) and the neighbourhood as 1丁目 (1-Chome).

There are some cases where quarter names and street names are named after neighbourhoods like 「字丁目」, for example in Yokohama and Matsudo City. The generally it is not possible to distinguish between them. In this case, the general rule is to connect the town and street name in the place=neighbourhood data entry。

Use of Kanji in Chome

(This section only refers to when tagging something in Japanese) In accordance with article 260, section 2 of the Local Autonomy Law, chome 「○丁目」(o-chome) are written using only kanji. In areas where non-kanji numerals are used, such as Hokkaido, the chome should be specified as「○条○丁目」(r-jou o-chome) using the numerals which are used in the region.

Quarter Name and Neighbourhood Tags

Quarter name「大字○○」(Town Name oo),「字○○」(name oo) place names, the「大字」and「字」can be left out. In this case, the abbreviated name can be placed in name=* and the complete name can be entered into official_name=*.

Prefixes of 町 and 村

In areas that have undergone municipal mergers, there are place names bearing the original names of towns or villages that existed before the merger. For example, for「郡山市安積町長久保一丁目」(Nagakubo 1-chome, Azumi Town, Koriyama City) you would use the tags place=neighbourhood+name=安積町長久保一丁目. On the other hand, in another example「郡山市日和田町広野入」(Hirono-iri, Hiyodacho, Koriyama City), the quarter name is place=quarter+name=日和田町 and the neighbourhood name is place=neighbourhood+name=広野入+official_name=字広野入. Please refer to the information published by the municipality to determine whether a place name is a quarter name or a neighbourhood name.

Place names including 区 (ward) also exist. For example in 「姫路市広畑区富士町」(Fuji-cho, Hirohata-ku, Himeji City), 「広畑区」(Hirohata-ku) is not a government designated ward. In this case, use the tag place=neighbourhood+name=広畑区富士町.

Neighbourhood Name Only Existing in the Registry

There are some areas where the neighbourhood name only exists in the official registry, and is not used in typical address notation. In these cases, neighbourhood names are not used in place=neighbourhood for mapping. The names of towns and neighbourhoods which are typically used should be included in place=neighbourhood. However, in areas such as some areas in Ryukesaki City, where the official address notation has the place number directly under the city and the neighbourhood name is used for convenience, the neighbourhood name is mapped as place=neighbourhood.

More examples

More examples of tagging various place names can be found in a spreadsheet.

Rules for place names

  1. Spelling of place name could be referred to Japanese and English Wikipedia.
    1. Value in Japanese for name and name:ja should be followed by 都, 道, 府, 県, 支庁, 郡, 市, 区, 町, 村, 丁目 when applicable.
    2. Value in English for name:en should be followed by Metropolis, Prefecture (except Hokkaido), Subprefecture, County, Ward (except 23 special wards of Tokyo), -chome when applicable; and should not be followed by City, Ward (only for 23 special wards of Tokyo), Town, Village. Not use letters with macron for long vowel of two moras in length such as ū and ō.
    3. Value in romanization of Japanese for name:ja-Latn should be followed by -to, , -fu, -ken, -shichō, -gun, -shi, -ku, -chō (or -machi), -mura (or -son), -chōme when applicable. Use letters with macron for long vowel of two moras in length such as ū and ō.
