On September 11, 2026, he led a live, two-hour workshop in Tokyo's Hibiya district where attendees used their own laptops to delegate real work tasks to Codex on the spot.
The live-only (no archive) July 9 event publicly disclosed, for the first time, how he uses Claude Code to automate his own Instagram and Threads operations end-to-end.
His official site (miyachi-aicrew.com) details an ongoing online course focused on helping executives and sole proprietors build their own AI-agent workflows without an engineering background.

Miyachi Ai, known online as みやっち (Miyacchi), is a Japan-based entrepreneur and AI practitioner who built a micro but focused following across YouTube and Instagram by documenting how solo business owners and small teams can replace headcount with AI agents. Unlike educators who teach AI concepts abstractly, Miyacchi's stated positioning is as someone actively running a company on tools like Claude Code and Codex — sharing live workflows, consulting case studies, and the reasoning behind implementation decisions. The channel's guiding premise, roughly translated as "Wait, AI can do that too?", frames each piece of content as a practical revelation aimed at sole proprietors, freelancers, and small professional firms rather than enterprise audiences. Recent output has broadened to cover adjacent tools including Microsoft 365 Copilot and AI-driven 3D generation platforms, suggesting a deliberate effort to map the expanding toolkit available to lean operations.
Miyachi_Ai reaches an audience concentrated in Japan primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories. As a tech creator they map naturally to brands targeting that space. With no brand deals logged yet, they read as an available, category-aligned partner for advertisers building early presence in the space. Engagement on YouTube runs around 1.1%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of long-form YouTube integrations and Instagram Reels and Stories lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows tech content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For Japan-focused brands in tech and related categories, Miyachi_Ai offers a defined, creative-fit audience rather than broad, low-intent impressions.

Miyachi_Ai (みやっち) deliberately frames themselves as a 実践者 — someone actively running AI agents inside their own company — rather than an expert who just explains concepts. Every tool they demonstrate is something they are already using in live business operations, so the channel is built around real-world results rather than theoretical walkthroughs.
Miyachi_Ai focuses heavily on Claude Code and Codex for building and deploying AI agents, and also covers ChatGPT and Microsoft 365 Copilot for everyday business workflows. Their content is aimed specifically at solo CEOs, small-team operators, freelancers, and licensed professionals (士業) who want to use these tools in real operations, not just experiments.
According to their own YouTube bio, the arrival of Claude Code and Codex caused a '180-degree' shift in how Miyachi_Ai works — and they say the same transformation has happened for their consulting clients and course students. This personal before-and-after story is the core credibility claim the whole channel is built around.
Miyachi_Ai explicitly targets 一人社長 (solo CEOs), small-team business owners, freelancers, and licensed professionals such as accountants and lawyers (士業) in Japan. Their philosophy is 'grow AI clones of yourself instead of hiring more people,' so the content skews toward owners who want leverage without headcount.
Yes — Miyachi_Ai runs live online seminars announced primarily through their Instagram account, including flagship events framed as large-scale AI summits. They also mention consulting clients and enrolled students (受講生), indicating structured coaching or course offerings alongside the free channel content.
MigooAI appears consistently in Miyachi_Ai's hashtags alongside their AI business content, suggesting it is a product or service closely tied to their work. The exact relationship is best confirmed through their official LINE community or Instagram, where they share direct links and announcements.
TripoAI is an AI-powered 3D content generation platform, and Miyachi_Ai has featured it under the #tripoai and #ai3d hashtags as part of their broader mission of showing entrepreneurs unexpected ways AI can replace specialist tasks. Covering 3D tools fits their recurring argument that AI can effectively add capabilities to a small team that would otherwise require outside contractors.
Miyachi_Ai distributes bonus materials and priority seminar invitations through a free LINE registration, promoted under the hashtag #無料line登録で特典配布中. Sign-up links are shared via their Instagram profile and stories, which is currently their most frequently updated platform.
As of late 2026, Miyachi_Ai's YouTube channel has been on an extended hiatus of close to a year, making Instagram their primary active channel for ongoing content and announcements. Their YouTube library still contains evergreen tutorials — including a full Microsoft 365 Copilot guide aimed at complete beginners — which continue to attract viewers.
Miyachi_Ai is currently most active on Instagram, posting regularly about AI tools, business strategy, and upcoming seminars. Their YouTube channel remains available but has not seen new uploads recently, so Instagram and their LINE community are the best places to follow them for current content.
