Japan Tech Jobs Market Checker — Bilingual IT Salary Stats

What does an English-speaking tech job in Japan actually pay — and how many employers will even tell you? One call answers both, across the two English-language Japanese job boards that publish salary bands.

Most Japanese job boards hide pay entirely. That is why the headline number here is not just the median: it is salaryDisclosureRate — how many of the live roles publish a band at all — next to salaryRangeWidthMillionsJpy, how wide that published ¥8M ~ ¥16M band is. A wide band is negotiation headroom; a missing band is a market signal of its own.

Overview

The Actor reads two job boards in one run and returns one compact market record:

• salaryMinMillionsJpy / salaryMaxMillionsJpy / salaryMidMillionsJpy — min / p25 / median / p75 / max / average of the advertised bands, in ¥ millions per year
• salaryRangeWidthMillionsJpy — the distribution of max - min. The width of the advertised band is the negotiation range
• salaryDisclosureRate — how many of the matched roles published a band at all
• salaryByJapaneseLevel — the money question: does requiring Japanese pay more? Count, median low and median high per required Japanese level
• japaneseRequirement — none / conversational / business / fluent / unknown
• residency — Japan residents only vs. can apply from abroad vs. unknown
• remote, categoryTop, companyCount
• Optionally every matching role as its own record

Source	URL	What one request returns	Reported as
TokyoDev	https://www.tokyodev.com/jobs	every listed position, server-rendered, no pagination	basis: "population"
JapanDev	https://japan-dev.com/jobs	60 of the listed jobs; the board exposes no pagination endpoint	basis: "sample"

Both counts are always reported separately, per source, as totalListed and sampled. JapanDev's listed total is never counted as sampled — the summary's sampledJobs only ever adds up what was actually read.

Each source's basis says what the returned statistics actually describe:

basis	Meaning
population	every listed job on that board is in the statistics
filtered_population	the board served every listed job, but a keyword / japaneseLevel filter kept only part of them, so the statistics describe that subset — the summary's basisFilter carries the filter that produced it
sample	the board served only part of its listed jobs, so the statistics are a sample. A filtered sample stays a sample

No login, no API key, no browser, nothing stored between runs. A run is 2 HTTP requests and takes a few seconds.

Input

Field	Example	Notes
sources	["tokyodev", "japandev"]	Which boards to aggregate. Default: both. Adding a board costs nothing extra
keyword	"backend"	Optional, case-insensitive, matched against job title + company. Empty = the whole English-speaker tech market
japaneseLevel	"any"	any / none / conversational / business / fluent. Filters the roles the statistics describe
includeIndividualItems	false	Enable to also get one record per matching role (+$0.002 each)

The perSource, totalListed, sampledJobs and disclosure counts are measured; the salary figures above show the record's shape — the actual distribution is whatever the boards publish on the day you run it.

With includeIndividualItems: true you additionally get one record per matching role:

{
  "type": "job",
  "source": "tokyodev",
  "title": "Engineering Manager",
  "company": "SPIKE STUDIO",
  "salaryMinMillionsJpy": 8.0,
  "salaryMaxMillionsJpy": 16.0,
  "japaneseLevel": "business",
  "japaneseLevelBasis": "exact",
  "residency": "japan_residents_only",
  "remote": "Fully remote",
  "location": null,
  "category": "Engineering Management",
  "url": "https://www.tokyodev.com/companies/spike-studio"
}

Pricing — from $0.02 per call, no subscription

Event	Price	When
Market summary (market-analyzed, primary event)	$0.02	Once per run
Individual job record (job-scraped)	$0.002	Only if you enable Include individual job records

A default run (both boards, summary only) costs $0.02. Individual records are off by default. A run that returns no jobs — or whose filters match none — is never charged.

Notes & limits

• Wantedly is deliberately not a source. It is the largest English-friendly board in Japan, but it does not publish salaries, and folding a salary-less board into a salary distribution would silently deflate every statistic here
• JapanDev is a sample, and says so. Its page server-renders 60 of its listed jobs and the board offers no pagination endpoint, so basis: "sample" and its totalListed is reported next to — never added into — sampled
• A filtered run is never labelled a population. Set a keyword or a japaneseLevel and every statistic describes the matching roles only, so TokyoDev's basis comes down to filtered_population and basisFilter records the filter that produced it. Sample-vs-population labelling is treated as correctness here, not decoration
• JapanDev's Japanese signal is coarser than TokyoDev's. It publishes only "Japanese Required" vs. nothing, so its roles map onto business / none and every such record carries japaneseLevelBasis: "coarse". TokyoDev's four-level labels are "exact"
• Residency is asymmetric on purpose. On TokyoDev, roles without the "Japan residents only" label were measured to be open to applications from abroad, so absence is a value. On JapanDev only the positive "Apply from Abroad" tag exists, so its absence stays unknown rather than being guessed
• location is only published by JapanDev; category is only published by TokyoDev. Both stay null on the other board rather than being invented
• TokyoDev's job URLs are not reliably extractable from the listing page, so url is nullable
• These are advertised bands, not offers or paid salaries, and they exclude bonuses, stock and allowances. Roles that publish no band are counted, never imputed
• If a board's page states a job count but no job can be parsed, the run fails that source instead of reporting zero — a layout change must not look like an empty market. If every source fails, the run fails
• Read-only, HTTP only (no browser), throttled at 1 request / 1.5 s, 256 MB, ~2 requests per run
• No personal data. Job posts carry employer names only; recruiter and applicant names are neither parsed nor emitted

日本語ガイド

日本の英語話者・バイリンガル向け IT 求人の「給与レンジ相場」を、1コール1レコードで返す Actor です。

• 概要: 給与を公開している英語圏向け求人ボード2つ（TokyoDev / JapanDev）を1回の実行で集計し、募集中求人の 年収レンジ（¥百万円単位）の分布（最小・p25・中央値・p75・最大・平均）を返します。売りは2つ — salaryDisclosureRate（そもそも給与を公開している求人の割合） と salaryRangeWidthMillionsJpy（¥8M ~ ¥16M というレンジの幅＝交渉余地）。日本の求人媒体は給与非公開が主流なので、「N件中何件が金額を出しているか」自体が価値のある指標です。
• 主な出力: 求める日本語レベル別の内訳と salaryByJapaneseLevel（日本語要件が上がると給与も上がるのか＝中央値の下限・上限）、在住要件（日本在住者限定／海外から応募可／不明）、リモート区分、職種カテゴリ上位、企業数。
• 母集団とサンプルの区別: TokyoDev は1リクエストで掲載中の全件が返るため basis: "population"。JapanDev は掲載件数のうち 60件のみが HTML に含まれ、ページング API が存在しないため basis: "sample" とし、totalListed（掲載総数）と sampled（実際に読めた件数）を必ず分けて報告します。JapanDev の掲載総数を sampledJobs に足すことはありません。
• basis の値: population（そのボードの掲載全件が統計に入っている）/ filtered_population（全件は取得できたが keyword・japaneseLevel で絞り込んだため、統計はその部分集合の説明。絞り込み条件はサマリーの basisFilter に入ります）/ sample（ボードが掲載の一部しか返さないためサンプル。絞り込んでも sample のまま）。
• 使い方: sources で対象ボードを選び（既定は両方）、keyword で職種名・社名の部分一致フィルタ（任意）、japaneseLevel で日本語要件による絞り込み（any / none / conversational / business / fluent）。個別求人の明細が必要なときだけ includeIndividualItems を ON にします。
• 料金: サマリー1件（イベント market-analyzed）$0.02、個別求人レコード（イベント job-scraped）は $0.002/件（既定 OFF なので既定実行は $0.02 固定）。0件・フィルタ不一致の実行には課金されません。 サブスクリプション不要です。
• 注意: Wantedly は給与が公開されていないため意図的に対象外です（給与統計が壊れるため）。JapanDev の日本語要件は「Japanese Required の有無」しかないため business / none に丸め、該当レコードには japaneseLevelBasis: "coarse" を付けます。掲載件数が取れているのに求人が1件も解析できない場合は、0件として返さずそのソースを失敗させます（レイアウト変更を空の結果と誤認しないため）。掲載されている金額は「提示レンジ」であり、賞与・株式・各種手当は含みません。個人情報は取得しません（企業名のみ）。

中文说明

一次调用即可获取日本「英语／双语 IT 职位」的薪资区间行情。

• 概览: 本 Actor 同时读取两个公开薪资的英文日本招聘网站（TokyoDev / JapanDev），返回在招职位的年薪区间分布（单位：百万日元）——最小值 / p25 / 中位数 / p75 / 最大值 / 平均值。核心卖点有两个：salaryDisclosureRate（究竟有多少职位公开了薪资） 与 salaryRangeWidthMillionsJpy（¥8M ~ ¥16M 这一区间的宽度，即议薪空间）。日本多数招聘网站根本不公开薪资，因此「N 个职位中有几个给出了金额」本身就是有价值的指标。
• 主要输出: 按所需日语水平拆分的分布与 salaryByJapaneseLevel（要求日语是否更高薪：各水平的下限中位数与上限中位数）、居住要求（仅限日本居住者／可从海外申请／未知）、远程办公构成、职位类别 Top 10、公司数量。
• 总体与样本严格区分: TokyoDev 单次请求即可返回全部在招职位，故标记为 basis: "population"；JapanDev 页面仅服务端渲染其中 60 条且不提供任何分页接口，故标记为 basis: "sample"，并将 totalListed（挂牌总数）与 sampled（实际读取数）分开报告。JapanDev 的挂牌总数绝不会被计入 sampledJobs。
• basis 取值: population（该站点在招职位全部纳入统计）/ filtered_population（虽已取得全部职位，但 keyword／japaneseLevel 只保留了其中一部分，因此统计描述的是该子集；产生它的筛选条件记录在汇总的 basisFilter 中）/ sample（站点本身只返回部分职位，故为样本；加了筛选仍然是 sample）。
• 用法: 用 sources 选择数据源（默认两个都用）；keyword 为可选的职位名／公司名不区分大小写筛选；japaneseLevel 按日语要求筛选（any / none / conversational / business / fluent）；只有在需要逐条职位明细时才打开 includeIndividualItems。
• 价格: 每次调用的汇总记录（事件 market-analyzed）$0.02，逐条职位记录（事件 job-scraped）$0.002/条（默认关闭，因此默认运行固定为 $0.02）。没有结果、或筛选后无匹配的运行不会计费。 无需订阅。
• 注意: Wantedly 不公开薪资，故有意不作为数据源（混入会破坏薪资统计）。JapanDev 只有「Japanese Required」有无之分，因此归并为 business / none，并在相应记录上标注 japaneseLevelBasis: "coarse"。若页面给出了职位总数却一条都解析不出，本 Actor 会让该数据源失败而非返回 0（避免把版面改动误判为「市场为空」）。所列金额为招聘方公示区间，不含奖金、股权与各类津贴。不采集任何个人信息（仅公司名称）。
