Blog #1: Bridging Japan and Europe: How to Turn Strategy into Systems that Scale

  • Why “bridge” work fails (and how to avoid it)
  • The MJ 3-Loop: Build → Measure → Standardize
  • Case patterns: What actually works (JP ↔ EU)
  • The five documents every cross-border GTM needs
  • Live commerce & remote production: practical setup
  • Culture and pace: what changes, what doesn’t
  • Start small: a 14-day plan you can copy
  • How MJ Consulting helps

Most companies don’t lack strategy. They lack a system that turns strategy into consistent results.

At MJ Consulting, we work between Japan and Europe, helping teams move from slides and roadmaps to repeatable operations—especially in live commerce, remote production (WRIDGE Live/RCA), and HW/SW advisory. This first post lays out our approach so you can apply it tomorrow, with or without us.


How MJ Consulting helps

  • Go-to-Market & Growth: Positioning → LP → weekly KPI loop.
  • Remote Production (WRIDGE Live/RCA): Cloud switcher setup, multi-cam workflows, remote tours.
  • HW/SW Advisory: Test design, logging/analysis, quality gates, offshore coordination.
  • Partner Introduction in Japan: Reliable collaborators and suppliers to move faster.

If you’d like help, we’ll set up a 0→1 Diagnostic (2–3 weeks) and leave you with a 90-day plan and the five documents above.
