このページでは、Place
クラス(新規)と PlacesService
(以前のクラス)で使用される近隣検索の違いについて説明し、比較用のコード スニペットをいくつか紹介します。
- 以前の
PlacesService
には nearbySearch()
メソッドがあり、指定された範囲内で、キーワードやタイプによる場所の検索が可能です。
Place
クラスには searchNearby()
メソッドがあり、場所データ フィールドと場所タイプの選択肢を拡大して柔軟性を高め、場所の種類で指定されたエリア内の場所を検索できます。
次の表に、Place
クラスと PlacesService
の近隣検索メソッドの主な違いをいくつか示します。
コードの比較
このセクションでは、近隣検索メソッドのコードを比較して、Places Service と Place クラスの違いを示します。コード スニペットは、テキストベースの検索リクエストを行うために各 API で必要なコードを示しています。
Nearby Search(従来版)
以前の Nearby Search では、指定された範囲内で、キーワードやタイプによる場所の検索が可能です。場所データ フィールドを使用して検索を制限することはできません。そのため、利用可能なすべてのフィールドが各リクエストとともに返されます。次のスニペットは、nearbySearch()
を呼び出してオーストラリアのシドニーにあるレストランに関する情報を返す方法を示しています。リクエストは同期型で、コールバックを使用し、PlacesServiceStatus
の条件付きチェックを含みます。
let map;
let service;
function initMap() {
const sydney = new google.maps.LatLng(-33.867, 151.195);
map = new google.maps.Map(document.getElementById("map"), {
center: sydney,
zoom: 15,
});
const request = {
location: sydney,
radius: '500',
type: ['restaurant']
};
service = new google.maps.places.PlacesService(map);
service.nearbySearch(request, callback);
}
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
// Helper function to create markers.
function createMarker(place) {
if (!place.geometry || !place.geometry.location) return;
const marker = new google.maps.Marker({
map,
position: place.geometry.location,
title: place.name,
});
}

Nearby Search(新規)
新しいバージョンの Nearby Search では、以前のバージョンから次のような点が改善されています。
- 返す場所データ フィールドを指定する機能。
- 非同期オペレーションを可能にする Promise の使用。
PlacesService
のステータスを確認する必要はありません。代わりに標準のエラー処理を使用できます。
次のコード スニペットは、レストランの Nearby Search リクエストを行う関数を示しています。この例では、rankPreference
オプションを使用して、検索結果を人気度でランク付けする方法を示します(前のバージョンでは、rankBy
オプションを使用してランキングを指定しています)。searchNearby()
メソッドは await
演算子を使用するため、async
関数内でのみ使用できます。
async function nearbySearch() {
// Restrict within the map viewport.
let center = new google.maps.LatLng(52.369358, 4.889258);
const request = {
// Required parameters.
fields: ["displayName", "location", "businessStatus"],
locationRestriction: {
center: center,
radius: 500,
},
// Optional parameters.
includedPrimaryTypes: ["restaurant"],
maxResultCount: 5,
rankPreference: google.maps.places.SearchNearbyRankPreference.POPULARITY,
language: "en-US",
region: "us",
};
const { places } = await google.maps.places.Place.searchNearby(request);
if (places.length) {
console.log(places);
// Create a new bounds, which will be extended with each result.
const bounds = new google.maps.LatLngBounds();
// Loop through and get all the results.
places.forEach((place) => {
const markerView = new google.maps.marker.AdvancedMarkerElement({
map,
position: place.location,
title: place.displayName,
});
bounds.extend(place.location);
console.log(place);
});
map.fitBounds(bounds);
} else {
console.log("No results");
}
}

[null,null,["最終更新日 2025-09-05 UTC。"],[],[],null,["# Migrate to the new Nearby Search\n\n\u003cbr /\u003e\n\n**European Economic Area (EEA) developers** If your billing address is in the European Economic Area, effective on 8 July 2025, the [Google Maps Platform EEA Terms of Service](https://cloud.google.com/terms/maps-platform/eea) will apply to your use of the Services. Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nThis page explains the differences between nearby search as used in the\n[`Place`](/maps/documentation/javascript/reference/place) class (new) and the\n[`PlacesService`](/maps/documentation/javascript/reference/places-service)\n(legacy), and provides some code snippets for comparison.\n\n- The legacy `PlacesService` has a `nearbySearch()` method, which lets you search for places within a specified area by keyword or type.\n- The `Place` class has a `searchNearby()` method which lets you search for places within a specified area by place type, utilizing an expanded selection of place data fields and place types for greater flexibility.\n\nThe following table lists some of the main differences in nearby search methods\nbetween the `Place` class and `PlacesService`:\n\n| [`PlacesService`](/maps/documentation/javascript/reference/places-service) (Legacy) | [`Place`](/maps/documentation/javascript/reference/place) (New) |\n|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [`nearbySearch()`](/maps/documentation/javascript/reference/places-service#PlacesService.nearbySearch) | [`searchNearby()`](/maps/documentation/javascript/reference/place#Place.searchNearby) |\n| [`PlaceSearchRequest`](/maps/documentation/javascript/reference/places-service#PlaceSearchRequest) | [`SearchNearbyRequest`](/maps/documentation/javascript/reference/place#SearchNearbyRequest) |\n| Requires the use of a callback to handle the results object and `google.maps.places.PlacesServiceStatus` response. | Uses Promises, and works asynchronously. |\n| Requires a `PlacesServiceStatus` check. | No required status check, can use standard error handling. [Learn more](/maps/documentation/javascript/reference/errors). |\n| Supports only location bias. | Supports location bias and location restriction. |\n| Returns all available data fields (a [subset of the supported fields](/maps/documentation/places/web-service/place-data-fields#places-api-fields-support)); cannot be constrained to specific fields. | Returns only the requested [place data fields](/maps/documentation/javascript/place-class-data-fields); the `Place` class offers an expanded and regularly updated selection of fields. |\n| Limited to a fixed set of [place types](/maps/documentation/javascript/supported_types). | Access an expanded and regularly updated selection of [place types](/maps/documentation/javascript/place-types). |\n| Supported text-based search with the [keyword](/maps/documentation/javascript/reference/places-service#PlaceSearchRequest.keyword). | Text-based search is not supported, use [Text Search (New)](/maps/documentation/javascript/places-migration-search#place-class-new) instead. |\n\nCode comparison\n---------------\n\nThis section compares code for nearby search methods to illustrate the\ndifferences between the Places Service and the\nPlace class. The code snippets show the code\nrequired on each respective API to make a text-based search request.\n\n### Nearby Search (Legacy)\n\nThe legacy Nearby Search lets you search for places within a specified area by\nkeyword or type. There is no way to constrain searches by using place data\nfields, so that all of the available fields are returned with each request.\nThe following snippet shows calling `nearbySearch()` to return information about\nrestaurants in Sydney, Australia. The request is synchronous, uses a callback,\nand includes a required conditional check on `PlacesServiceStatus`. \n\n let map;\n let service;\n\n function initMap() {\n const sydney = new google.maps.LatLng(-33.867, 151.195);\n\n map = new google.maps.Map(document.getElementById(\"map\"), {\n center: sydney,\n zoom: 15,\n });\n\n const request = {\n location: sydney,\n radius: '500',\n type: ['restaurant']\n };\n\n service = new google.maps.places.PlacesService(map);\n service.nearbySearch(request, callback);\n }\n\n function callback(results, status) {\n if (status == google.maps.places.PlacesServiceStatus.OK) {\n for (var i = 0; i \u003c results.length; i++) {\n createMarker(results[i]);\n }\n }\n }\n\n // Helper function to create markers.\n function createMarker(place) {\n if (!place.geometry || !place.geometry.location) return;\n\n const marker = new google.maps.Marker({\n map,\n position: place.geometry.location,\n title: place.name,\n });\n }\n\n#### Learn more\n\n- [See the documentation for legacy Nearby Search](/maps/documentation/javascript/places#place_search_requests)\n- [See the `searchNearby()` reference](/maps/documentation/javascript/reference/places-service#PlacesService.nearbySearch)\n\n### Nearby Search (New)\n\nThe new version of Nearby Search improves upon its predecessor in the following\nways:\n\n- The ability to specify which place data fields to return.\n- The use of Promises which enables asynchronous operation.\n- No need to check for the status of `PlacesService`; standard error handling can be used instead.\n\nThe following code snippet shows a function which makes a Nearby Search request\nfor restaurants. This example shows using the `rankPreference` option to rank\nsearch results by popularity (in the previous version ranking is specified\nusing the `rankBy` option). Because the `searchNearby()` method uses the `await`\noperator it can only be used inside an `async` function. \n\n async function nearbySearch() {\n // Restrict within the map viewport.\n let center = new google.maps.LatLng(52.369358, 4.889258);\n const request = {\n // Required parameters.\n fields: [\"displayName\", \"location\", \"businessStatus\"],\n locationRestriction: {\n center: center,\n radius: 500,\n },\n // Optional parameters.\n includedPrimaryTypes: [\"restaurant\"],\n maxResultCount: 5,\n rankPreference: google.maps.places.SearchNearbyRankPreference.POPULARITY,\n language: \"en-US\",\n region: \"us\",\n };\n\n const { places } = await google.maps.places.Place.searchNearby(request);\n\n if (places.length) {\n console.log(places);\n\n // Create a new bounds, which will be extended with each result.\n const bounds = new google.maps.LatLngBounds();\n\n // Loop through and get all the results.\n places.forEach((place) =\u003e {\n const markerView = new google.maps.marker.AdvancedMarkerElement({\n map,\n position: place.location,\n title: place.displayName,\n });\n\n bounds.extend(place.location);\n console.log(place);\n });\n map.fitBounds(bounds);\n } else {\n console.log(\"No results\");\n }\n }\n\n#### Learn more\n\n- [See the complete example code](/maps/documentation/javascript/examples/place-nearby-search)\n- [See the documentation for Nearby Search (New)](/maps/documentation/javascript/nearby-search)\n- [See the `searchNearby()` reference](/maps/documentation/javascript/reference/place#Place.searchNearby)"]]
