Why this seat is different in Japan

Customer success is a young function in Japan and the customer did not ask for it. Japanese enterprise buyers grew up with vendor support (サポート) that answers the phone, visits the office and fixes things, and with account managers who manage the relationship. A success plan, a quarterly business review and a health score read as process imposed by the vendor unless they are translated into something the customer recognises: a regular meeting (定例会) with written minutes, a named contact who turns up, and reporting the customer can forward to their own management.

Renewal runs on the customer's calendar. Budgets close at the end of March for most Japanese companies, renewal decisions go through an internal approval circuit (稟議) that starts months earlier, and a lapse in the paperwork can delay a renewal past the fiscal year even when the customer is happy. The customer-success head must know the customer's cycle better than the customer does.

Many customers arrive through partners. System integrators, distributors and trading companies sell and often implement foreign software in Japan, and the end customer may never have met the vendor. The customer-success head manages adoption and renewal through and around the partner, and must decide where the partner's relationship ends and the vendor's begins.

The product team is abroad and works in English. Every escalation, feature request and incident needs translating into terms the product organisation acts on, and the Japanese customer needs an answer in Japanese in the meantime. The person who can do both is the one every software company in Tokyo is trying to hire.

Purpose of the role

Own retention and expansion for the Japan customer base: build the customer-success function and its playbook for Japanese customers, lead the team, manage renewals and net revenue retention, and represent Japanese customers to product, support and leadership abroad.

Key responsibilities

Retention and expansion

  • Own gross and net revenue retention targets for Japan, with renewal forecasting the finance team can rely on.
  • Identify expansion and upsell with account executives and keep commercial alignment clear.

Customer engagement

  • Build the engagement model for Japanese customers: cadence, reporting, executive sponsorship and the written artefacts customers expect.
  • Lead onboarding and adoption programmes from implementation through steady state, directly and through partners.
  • Run executive relationships with the top accounts personally.

Risk and escalation

  • Analyse usage and health data to find risk early and act on it.
  • Manage escalations to support and product in English, and manage the customer in Japanese while they are resolved.

Team

  • Hire, coach and develop customer-success managers, and set standards for account coverage and documentation.

Voice of the customer

  • Feed Japanese requirements and feedback to product and marketing, with evidence.

Candidate profile

Must have

  • Eight or more years in customer-facing roles at a software or technology company in Japan, with at least three leading customer success, account management or a comparable function.
  • A track record of renewal and net revenue retention results, with the numbers.
  • Experience managing enterprise customers through Japanese decision processes, including partner-sold accounts.
  • Enough technical depth to understand the product, its integrations and its data.

Preferred

  • Experience building the function rather than inheriting it.
  • Consulting, pre-sales or implementation background.
  • Domain knowledge matching the product: marketing technology, data, security, finance, HR.

Language

  • Japanese at native level for customers and the team.
  • English at business level for product, support, regional leadership and incident management.

Decide before you post

  • Head with a team, or senior individual contributor with a book of accounts. The title and pay follow.
  • The net revenue retention target and current performance, which candidates will ask for.
  • The partner model and how much of the customer base is partner-managed.
  • How variable pay is structured: renewal, expansion, or both.
  • Whether the role carries a quota, and how it is split with sales.

How hard is this hire

Moderate to hard. Customer-success managers exist in reasonable numbers in Tokyo; leaders who have built the function for Japanese enterprise customers and can carry product escalations in English are few, and software companies compete for them with high variable pay. Expect three to four months. Searches fail when the playbook from headquarters is treated as fixed and the candidate is asked to run it rather than adapt it.

Interview questions that separate candidates

  • Show me your net revenue retention for the last two years and explain the accounts you lost.
  • Tell me how you run a renewal that has to clear a customer's approval circuit before the end of March.
  • Describe a partner-sold customer where adoption was failing. What did you do and whose relationship was it?
  • Walk me through an escalation to a product team abroad. What did you tell the customer while you waited?
  • What did you change in the global customer-success playbook for Japan?

Before you post in Japan

Before you post a job advert in Japan

Recruitment advertising falls under the Employment Security Act (職業安定法). The advert, or the first written offer, must state the job content, contract period, probation period, place of work, working hours, breaks, holidays and overtime, pay, social and labour insurance enrolment, the employer's name, whether the person would be a dispatched worker, and passive-smoking measures at the workplace. Since April 2024 the possible scope of changes to duties and place of work, and any cap on fixed-term renewals, must also be stated. The ministry updates the list; check it with your labour consultant.

What not to put in a Japan job description

No age range or age ceiling: unlawful in recruitment with narrow exceptions. No gender, nationality or "Japanese national" requirement; specify the language level instead. Do not require a photograph at application; it is customary on a 履歴書 but unnecessary for a senior hire and discouraged in fair-hiring guidance. Replace "native Japanese" with "Japanese at native or JLPT N1 level" and say what the English is for. Do not list "must be able to work overtime" as a requirement.
