Definition: Jisshi (実施) translates literally to ‘implementation,’ ‘carrying out,’ or ‘enforcement.’ In a Japanese business context, it represents the bridge between a approved plan and its physical manifestation. It carries a heavy weight of responsibility—once something is jisshi-sareta, it is officially ‘in motion’ and irreversible.
Early in my career in Tokyo, I once sent an email saying a project was ‘ready for jisshi.’ My boss immediately pulled me into his office to ensure every single checkbox of our Shinkouchuu phase was perfectly cleared. He wasn’t checking my progress; he was checking my commitment to the consequences of execution. In Japan, Jisshi isn’t just starting a task; it’s a declaration that you have accounted for every possible failure point.
Unlike the English word ‘execute,’ which can sound slightly aggressive or purely task-oriented, Jisshi implies a ritualistic adherence to the planned procedure. If you suggest that a policy should be jisshi-sareru (implemented), you are implying that it has passed the gauntlet of internal consensus—the ringi process—and is now the ‘law’ of the office.
Pro-tip: When discussing a new project, use Jisshi to signify commitment. If you are uncertain about the timeline, avoid this word at all costs. Instead, use Yousu-mi or Kento-chuu (under consideration). Saying Jisshi too early is seen as a sign of impulsiveness, which is a major red flag in Japanese management.
“Are we truly at the stage for jisshi? We haven’t confirmed the tsugou of the stakeholders in the Osaka branch yet.”
Common Mistakes Foreigners Make:
The biggest blunder I see expatriates make is using Jisshi as a synonym for ‘trying’ or ‘testing.’ Do not say you are ‘jisshi-ing’ a pilot project unless it is an official, approved rollout. If it’s a test run, use shiken-teki (experimental) or tameshi-ni (as a trial). Calling a half-baked experiment Jisshi implies to your Japanese counterparts that the project is finalized and ready for high-stakes scrutiny. The confusion this causes can lead to intense, unnecessary stress during meetings where everyone expects a fully realized result.
Furthermore, avoid using it as a verb too casually. Don’t say ‘I will jisshi this.’ Instead, use the formal phrasing Jisshi itashimasu (I will carry this out). It is a stiff, formal word, and it should be treated with the gravity it deserves. If you treat Jisshi like a generic task-word, you lose the professional edge you gain by demonstrating you understand the seriousness of corporate policy.
Ultimately, Jisshi is about alignment. It marks the moment where individual initiative stops and collective commitment begins. When you use it correctly, you signal that you are not just a worker, but someone who understands the weight of organizational movement. Pair this with the right O-tsukare-sama desu to acknowledge the team’s effort in getting to the implementation stage, and you will command significantly more respect in your next strategy meeting.
