Ten CVs land in your inbox from the agency you briefed two weeks ago. You open the first three, close them, and start composing a polite email about fit. The recruiter worked from the only document you gave them: a job posting written to pull in applicants, careful about what it promises, silent about everything that actually disqualifies a candidate.
One document is doing two jobs, and it fails at the second one. A public posting persuades strangers to apply. A recruiter needs a different document, a private briefing that says who to search for and what to screen out, and most companies never write one. Build both and you reduce recruitment costs while the CVs start matching.
Why Job Descriptions Fail Recruiters
85% of employers in Japan struggle to fill roles, among the highest rates anywhere, with unemployment at 2.5% in the June 2026 Labour Force Survey. Yet over 80% report hiring mismatches, so even the roles that do get filled often get filled wrong.
The failure follows a script. Talent Acquisition writes "B2B sales experience required." The hiring manager means enterprise SaaS sold to Japanese corporates. The recruiter takes the words at face value and submits candidates from SMB and transactional B2B backgrounds. Three people did their jobs correctly and the search still went nowhere, because the words on the page carried less than half the requirement.
What a Bad Brief Actually Costs
En Japan research puts the total loss above ¥1,875,000 when an employee leaves within three months. Hiring a mid-career replacement costs ¥1,033,000 on average before you count agency fees, interviewer hours, and onboarding. A departure in month two turns into a seven-figure hole, and the search that produced it starts over from zero. Someone then asks whether the agency was bad, the brief was bad, or the market was thin. In my experience the brief takes the blame far less often than it deserves.
Public Job Posting vs Private Agency Briefing
The document you post and the document you hand an agency serve different readers with opposite needs.
A public job posting is employer branding. It has to be inclusive, legally clean, and broad enough that good people see themselves in it. Half of what determines a hire has no business appearing in it.
A private agency briefing exists to sharpen a recruiter's search. It holds the target companies, the ranked requirements, the manager's preferences, and the dealbreakers you'd never publish, everything a recruiter can use to filter before a CV reaches you.
The Two-Document Approach
What an Ideal Candidate Profile Covers
An Ideal Candidate Profile (ICP) is a private document describing the person you want to hire: experience as a range, required skills, English level, the companies your ideal candidate works at today, and dealbreakers, each ranked by priority. A job description lists what the role involves; the ICP records who succeeds in it. Almost all job-description advice optimizes the public posting for job boards and skips the document your agencies depend on.
What Recruiters Need From You
Beyond the posting, four kinds of context change what a recruiter can find for you.
Priorities. Separate must-have from nice-to-have explicitly. Faced with a flat list of eight requirements, a recruiter has to guess which three are real.
Hidden criteria. The manager trusts people from larger companies. The team needs someone blunt. The last hire fell apart working remotely. None of that belongs in a posting, and all of it sharpens a search.
Unpostable dealbreakers. Some circumstances make the role unworkable, and saying so publicly would be somewhere between awkward and illegal. Say it privately instead.
Timeline. A backfill for someone who resigned yesterday gets worked differently than a new headcount with a soft start date. Tell the recruiter which one this is.
The Best/Better/Normal Framework
Tier the requirements so recruiters know when a near-miss is worth submitting:
- Best: Enterprise SaaS sales in Japan, selling to Japanese corporates, bilingual
- Better: Enterprise SaaS anywhere, comfortable with Japanese business culture
- Normal: B2B sales, demonstrated success in complex cycles
"B2B sales experience" leaves a recruiter guessing. "Enterprise SaaS sales to Japanese corporates" gives them a search they can run, and the tiers tell them how far from ideal they're allowed to stray.
How to Build Your Ideal Candidate Profile
A useful ICP captures what makes someone right for the role, including the parts that never show up on a resume.
Skills and Experience
- Years: Give a range like 5-8. A bare "5+" says nothing about when a candidate is too senior
- Industry: Name the backgrounds that translate and the ones that look similar but don't
- Skills: Split what's required on day one from what a smart hire picks up in a quarter
- English level: Business fluency for negotiations, or enough to survive a weekly call?
- Certifications: Required by regulation, or a preference someone once mentioned?
Team Context
Some things belong in the briefing conversation instead of the written profile:
- Does the team collaborate constantly, or does everyone run their own patch?
- How does the manager actually manage?
- What went wrong with the last person in the seat, and what has to be different?
- Any team dynamics the new hire will walk into?
Logistics
- Location: Remote, hybrid, or in the office, and how firm is that?
- Salary: The range you'd genuinely pay, and the stretch for an exceptional candidate
- Start date: Hard deadline or flexible?
- Visa: Can you sponsor, and do you want to?
Beyond the Resume
The bilingual pool in Japan is thin. Japan ranks 87th of 113 countries in English proficiency, so every English requirement you add shrinks the candidate pool. Japanese candidates also tend to undersell themselves; many qualified people won't raise their hand unless they meet every stated requirement. A recruiter armed with your real priorities can go find the strong candidate who would have self-selected out.
So record judgment calls, along with skills:
- Would the manager rather have ownership at a smaller company or a famous brand with narrow scope?
- Raw intelligence, or the exact experience?
- Where is there room to compromise, and where is there none?
Most companies hold all of this in fragments. Target companies live in someone's memory of a kickoff call. The skills list sits in a Slack thread. Nobody ever wrote down the priorities. Three weeks later you're explaining why five CVs missed, and neither side can find the notes that would settle it.
The fix is a structured format. Try building one now: set the experience range, skills, English level, and target companies, and rank what matters.
That's an Ideal Candidate Profile, exportable as a PDF. The scattered notes are what produced the ten CVs that missed; this one page is what produces the five that fit.
With the ICP in hand, you can also standardize how agencies respond to it. A recruitment RFP template makes every agency answer the same questions on fee, timeline, and track record, so their proposals line up side by side.
How to Brief a Recruitment Agency
The document carries half the load. The conversation around it carries the rest. A good briefing runs as a dialogue: the recruiter probes, you clarify priorities, both sides confirm what "great" means before anyone starts searching. Be suspicious of a recruiter who takes the ICP and asks nothing.
The Briefing Checklist
Role purpose
- What does success look like at six months? At a year?
- What problem does this hire solve?
- Why is the role open now?
Team structure
- Who manages this person, and how?
- Who are the peers, and how does the team run?
- Any friction the new hire should know about?
Company context
- What stage is the company at, and where is it headed?
- Which selling points land with candidates?
- What objections come up, and how do you answer them?
Compensation
- The real budget, separate from the posted range
- How much stretch exists for the right person
- Which benefits candidates actually care about
An exclusive agency partner will dig into these questions far more deeply than a contingency recruiter up against four competitors, and the alignment shows up in the CVs.
Explain the Why Behind Each Requirement
A requirement without its reason forces the recruiter to apply it literally.
Instead of: "Must have 5 years of experience."
Try: "We need someone who's seen scale. Our last two hires were great ICs but struggled when the team grew. We need someone who's been through that transition."
Now the recruiter can judge. A candidate with four years who led a team through 3x growth gets submitted, because the recruiter knows what the five years was standing in for.
Three Mistakes That Produce Mismatched Candidates
Even with a solid ICP and a real briefing, three habits keep derailing searches.
The Unicorn Trap
Ten years of experience, plus the exact industry, plus bilingual, plus a specific degree, plus management experience. Stack every "and" and you've described three people in the country, all of them happily employed. Tier the requirements instead, and decide in advance what you'd trade away for an otherwise exceptional candidate.
Keyword Over-Reliance
An ATS screens on exact words, so qualified people who described their experience differently never surface. Your ICP should carry the translations: "We call it X; candidates from these companies will say Y." You're handing the recruiter vocabulary for matches you'd otherwise never see.
No Feedback Loop
"Not a fit" teaches an agency nothing. "Strong technical skills, but the manager felt they'd struggle with our pace" recalibrates the next search. Send specific notes after every CV review; each round of feedback narrows the gap between what you asked for and what arrives. In a market where every agency hears vague briefs all day, clarity is a competitive advantage.
From ICP to Better Candidates in Four Steps
Write the ICP first. Start from what the manager actually wants: hidden criteria, ranked priorities, dealbreakers, and the line between good and great.
Derive the public posting from it. Lift the shareable parts, the role overview, key responsibilities, and must-have qualifications, and write those for candidates.
Brief agencies with the whole picture. Share the ICP, then talk it through, so recruiters have the context to make judgment calls on your behalf.
Feed back after every batch. When candidates miss, say why. When one comes close, say what was missing. The next batch improves because the agency now knows things the first brief couldn't carry.
Agencies that know your hidden criteria stop spending their hours, and yours, on mismatches. AirTA is a marketplace where agencies see your Ideal Candidate Profile before they propose on your search.
