Yokohama is Japan's second-largest city by population and the anchor of the Keihin Industrial Belt — automotive (Nissan HQ in Minato Mirai), shipbuilding (MHI Yokohama), heavy industry, ports, and an emerging tech cluster in Minato Mirai. NKKTech is built for Japanese enterprise IT — Tony Nguyen spent 10 years at Toyota, Sony, and Rakuten in Tokyo and Osaka. Senior team includes native-Japanese engineers. JST-hours daily overlap with Vietnam (2-hour difference only).
Six engagement patterns we run most often for Yokohama-based clients. Adapted for Japanese enterprise IT expectations and Keihin manufacturing-belt operating norms.
Daily standups, PRs, design docs, and stakeholder reports in Japanese when needed. Senior engineers with N1 / business-fluent Japanese. Tony joins critical conversations directly (10 years enterprise Japan experience).
Documentation matches Japanese enterprise expectations: 詳細設計書 (detailed design docs), 運用手順書 (operations runbooks), 試験仕様書 (test specifications). The Keihin-belt manufacturers especially demand this rigor — we deliver it as default, not as an extra.
Factory computer vision QA (defect detection, OEE), predictive maintenance for industrial equipment, multilingual knowledge agents for global plants, supply-chain visibility, document OCR for trade-heavy manufacturers. 3-year PrismLab AI/AR partnership track record.
Vietnam GMT+7, Japan GMT+9 — only 2 hours difference. Daily sync window 10am-5pm JST = 8am-3pm Vietnam. We do morning standup in your hours, hand off via async docs in afternoon. Much smoother than US engagements.
Tony or senior engineers fly to Yokohama from Hanoi (~5h direct flight to Haneda, 30 min by limousine bus to Minato Mirai). 2-4 week on-site embeds available at your office when project requires. Hotel and meeting-room logistics handled by us.
Default: Singapore-law MSA via NKKTech Global Pte. Ltd. for cleaner IP terms. For clients requiring Japan-law: partner counsel relationship in Tokyo/Yokohama for client-specific structures. NDA + DPA templates in both Japanese and English.
30 minutes via Zoom or Google Meet, scheduled in JST. Tony joins for strategic discussions; senior engineer for technical. Conducted in Japanese or English depending on your preference.
Detailed proposal in Japanese-business format: 提案書, scope definition, 見積書 (quote), schedule. Reviewable by your in-house IT + legal. Yokohama-headquartered manufacturers often add 2-3 days for internal approval cascade.
JST-hours sync, weekly demo (often in Japanese), milestone-based payment. On-site visits at kickoff + week 4 + week 12 in Minato Mirai or your factory site. Documentation produced as you go.
Production launch + comprehensive handoff documentation. Optional 保守契約 (maintenance contract) for ongoing operation: typically ¥800K-1.5M/month for active retainer.
Nissan HQ + Tier-1/Tier-2 supplier network. Factory CV for defect detection, predictive maintenance for press lines + paint shops, knowledge agents for global supplier coordination, multilingual technical document automation.
MHI Yokohama, Hitachi Industrial, JFE shipyards. Predictive maintenance for industrial turbines, document OCR for engineering drawings, compliance-aware AI for safety-critical systems, multilingual maintenance instruction generation.
Yokohama is Japan's #2 container port. Shipping document OCR (multilingual), customs automation, route optimization, container-tracking agents. We've shipped on trade-heavy data flows.
Engineering team augmentation, internal tools, AI feature shipping inside core products. Common: 3-6 month engagements with embedded senior engineers, JST-hours coverage.
Document automation for clinical-research workflows, multilingual literature review agents, chem-document OCR. Compliance-aware patterns (PMDA + ICH-GCP).
Knowledge-base agents (multilingual), student-service automation, document translation. Yokohama hosts several international university campuses.

Yokohama is 30-40 minutes from Tokyo Station by Shinkansen (Shin-Yokohama) or limousine bus from Haneda. We fly into Haneda (~5h direct from Hanoi) and limousine-bus directly to Minato Mirai, often without entering central Tokyo. For factory visits in Tsurumi, Isogo, or Kanazawa-ku, we coordinate hotel pickup + transport.
Keihin-belt manufacturers (especially Tier-1 automotive + heavy industry) demand longer internal approval cycles (3-6 weeks for MSA signature is typical), strict documentation discipline (we deliver 詳細設計書 + 試験仕様書 by default), and on-site visits to factory floors. We're built for this — not a surprise.
Default is Singapore-law via NKKTech Global Pte. Ltd. (cleaner for international IP). For Keihin-belt manufacturers requiring Japan-law contracts, we have a partner Japanese legal counsel relationship for client-specific MSAs. NDA + DPA templates are available in Japanese and English.
AI MVP for Japanese clients (10-14 weeks): JPY 6-12M fixed-fee. Larger Keihin-belt engagements: JPY 30-100M over 6-12 months. 保守契約 (ongoing retainer): JPY 800K-1.5M/month. すべて固定報酬 — no T&M surprises.
