Japan Comprehensive Service cheat sheet

The 5 service quality dimensions (RATER): Reliability, Assurance, Tangibles, Empathy, Responsiveness; reliability is the most important for customer perception.

SERVQUAL gap model: Gap 5 (customer expectation vs. perception) is the outcome of Gaps 1–4 (knowledge, standards, delivery, communication).

Customer lifetime value (CLV) = average purchase value × purchase frequency × customer lifespan; used to justify retention spending.

Service recovery paradox: a customer who experiences a well-handled failure can become more loyal than one who never had a problem.

Moments of truth: every customer contact point shapes perception; in Japanese service, these are called 'soten' (contact points).

The 3Ps of service marketing: People, Process, Physical evidence - added to the 4Ps because services are intangible and inseparable.

Complaint handling rule: acknowledge within seconds, listen fully, apologize for the experience (not necessarily fault), act, follow up.

Customer satisfaction = perceived performance − expectations; lowering unrealistic expectations can raise satisfaction without changing delivery.

Keigo has three registers: sonkeigo (respectful, elevates the other party), kenjōgo (humble, lowers oneself), teineigo (polite, neutral).

Sonkeigo pattern: o/go + verb stem + ni naru (e.g., o-machi ni naru); kenjōgo pattern: o/go + verb stem + suru (e.g., o-machi suru).

Common irregular respectful forms: irassharu (to go/come/be), ossharu (to say), nasaru (to do), goran ni naru (to see).

Common irregular humble forms: mairu (to go/come), mōsu (to say), itasu (to do), haiken suru (to see).

Aizuchi (back-channeling) such as 'hai', 'sō desu ne' signals listening; silence in Japanese conversation often means consideration, not disagreement.

Avoid double keigo (e.g., 'o-tsukare-sama de gozaimasu' is acceptable but 'go-ran ni nararemashita' is over-elevated); one respect layer is sufficient.

Inbound communication: use simple Japanese, avoid keigo overload, and confirm understanding with closed questions ('daijōbu desu ka?').

Email/phone rule: identify company and name first, state purpose, confirm key numbers/dates twice; use 'yōhai' (拝啓) and 'keigu' (敬具) in formal letters.

Ojigi (bow) types: eshaku (15°, light greeting), keirei (30°, business), saikeirei (45°, deep apology/reverence); angle measured from standing upright.

Meishi kōkan (business card exchange): hold with both hands, text facing the receiver, present after a brief bow; never write on a card in the presence of the giver without permission.

Seating order: kamiza (upper seat) is farthest from the door, near the tokonoma or best view; shimoza (lower seat) is nearest the door.

Door etiquette: the person of lower rank opens and holds the door, enters last, and says 'shitsurei shimasu' when entering.

Elevator order: lower-ranked person holds the door and operates the buttons; higher-ranked person enters first and exits last.

Oshibori (hot towel) is offered before meals; place it folded after use, not crumpled, and never use it on the face in formal settings.

Hō-ren-sō (report–contact–consult) is the standard internal communication flow: report to superiors, contact peers, consult before acting.

5S workplace discipline: seiri (sort), seiton (set in order), seiso (shine), seiketsu (standardize), shitsuke (sustain).

HACCP 7 principles: hazard analysis, CCP identification, critical limits, monitoring, corrective actions, verification, record-keeping.

Food safety temperature zones: keep hot food ≥65°C and cold food ≤10°C; the danger zone is 10–65°C where bacteria multiply fastest.

Hand hygiene steps: wet, soap, scrub 20 seconds including fingertips and between fingers, rinse, dry with single-use paper; alcohol rub is an alternative when hands are not visibly soiled.

Cross-contamination control: separate cutting boards by color (e.g., red for meat, green for vegetables), clean and sanitize between uses.

Allergen control: the 8 major allergens in Japan (shrimp, crab, walnut, wheat, buckwheat, egg, milk, peanut) must be declared; verify with the kitchen before serving.

Fire response: RACE - Rescue, Alarm, Contain (close doors), Extinguish/Evacuate; use a fire extinguisher with PASS (Pull, Aim, Squeeze, Sweep).

Earthquake response in service: secure guests first, do not use elevators, shelter under sturdy furniture, then evacuate to designated assembly point.

Employment Security Act: job advertisements must not include discriminatory conditions such as age or gender unless genuinely required.

Standard Operating Procedure (SOP) elements: purpose, scope, responsibility, step-by-step actions, records, revision history.

PDCA cycle: Plan (set targets), Do (execute), Check (measure results), Act (standardize or correct); used for continuous improvement (kaizen).

5W1H for task instructions: What, Why, When, Where, Who, How - ensures complete briefing.

Inventory control: par level = minimum stock + safety stock; reorder point = (average daily usage × lead time) + safety stock.

Quality inspection sampling: use AQL (Acceptable Quality Limit) tables to decide sample size and acceptance number; do not inspect 100% unless required.

Shift handover: use a written log covering incidents, unfinished tasks, customer requests, and equipment status; confirm verbally.

Service blueprint: maps frontstage actions, backstage actions, and support processes across the customer journey to find failure points.

Mystery shopper and CS surveys measure the gap between intended and delivered service; results feed into training and SOP revision.

Inbound tourist sources to Japan (pre-COVID): China, South Korea, Taiwan, Hong Kong, USA; service should anticipate different expectations for each.

Omotenashi is anticipatory hospitality - meeting needs before they are expressed - but it must not assume; ask when uncertain.

Muslim guests: provide halal-certified food, avoid pork and alcohol in ingredients, and indicate prayer space if available.

Vegetarian and vegan guests: dashi (fish stock) and bonito are common hidden ingredients; confirm before recommending dishes.

Cultural dimensions (Hofstede): Japan scores high on uncertainty avoidance and long-term orientation; service should be precise and consistent.

Language support: use pictograms, translation apps, and simple English; avoid idioms and honorifics that do not translate.
