Anthropic’s Code with Claude series closes out in Tokyo on June 10 — the third and final stop after San Francisco (May 6) and London (May 19). The in-person slots are full, but the global livestream is free. If you shipped anything on Claude in the last six months and haven’t tuned into the earlier events, Tokyo is worth four hours on a Wednesday.
The short version of why: this is not a marketing event. The San Francisco and London editions ran live demos of real production agent architectures, with Anthropic engineers acknowledging failure modes and edge cases rather than showcasing clean demos. The Tokyo edition is expected to follow the same format. Boris Cherny (Claude Code lead), Ami Vora (Anthropic CPO), and Angela Jiang (Claude API and SDK product lead) are all presenting.
There is also context specific to Japan that makes this event worth paying attention to even if you have no particular interest in the Japanese market. What’s happening with AI adoption in Japan right now is probably the clearest preview of what enterprise AI adoption looks like in markets that are disciplined, risk-aware, and investing in it seriously. That’s most of the enterprise market globally.
The Event Structure
Code with Claude Tokyo follows the same three-track structure as the prior two events.
Research track: Interpretability research updates, Constitutional AI developments, and what’s actually changing in the Claude model family. In San Francisco, this track included candid discussion of where the research team is still learning — which is more useful than a roadmap slide. Expect the Tokyo session to focus on what’s changed since May.
Claude Platform track: Production agent development — real case studies from companies shipping agents in production, platform best practices, and how the Agent SDK billing split (live June 15) changes the economics of running agentic workflows at scale. If you’re building anything that uses claude -p or the Agent SDK in production, this track is directly applicable.
Claude Code track: Boris Cherny’s domain. The confirmed session is “Beyond the Basics with Claude Code” — covering long-horizon tasks, multi-repo agent work, parallel agent execution, and the infrastructure considerations that don’t fit in a getting-started guide. The San Francisco and London sessions in this track included live demonstrations that went intentionally off-script to show what happens when Claude Code gets confused or makes wrong assumptions. That’s more useful than the official docs.
The June 11 Extended Event
There is a second-day event on June 11 — Code with Claude Extended Tokyo. This one is different in audience and format. The main June 10 conference is for the broader developer community. Extended targets independent developers and early-stage founders.
Extended is not livestreamed, but sessions will be recorded and posted publicly afterward. The format is laptops-open workshops with Anthropic’s Applied AI team — builders working on real projects, not staged demonstrations. Founder stories from people who have already shipped products on the Claude platform.
If you’re an indie builder or early-stage founder and you’re in Tokyo, Extended is the higher-signal day. The main event is where you hear what’s new. Extended is where you see it working in real products.
Why Japan, Why Now
The Tokyo event sits inside a week that has been notably active for Anthropic’s Japan strategy.
On June 3 — the day before this article — Japanese government agencies and major banks gained access to Claude Mythos, the highest-capability tier of Claude that has been rolling out regionally on a controlled basis. Japan joins a relatively small group of markets that have cleared Mythos access; the EU is still waiting. (See our earlier coverage of how Mythos access has been allocated globally.)
Two major enterprise partnerships are already in place:
NEC Corporation became Anthropic’s first Japan-based global partner. Claude is being deployed to approximately 30,000 NEC Group employees worldwide. NEC is building what it describes as one of Japan’s largest AI-native engineering organizations — engineers working with Claude as a core development tool, not as an optional productivity add-on.
Hitachi announced a partnership in May 2026 focused on what Hitachi calls “physical AI” — applying Claude reasoning to transportation systems, power generation, manufacturing processes, and financial operations. Hitachi’s framing is significant: they’re treating Claude as infrastructure for industrial AI rather than an enterprise chatbot. That’s a different kind of integration than most Western enterprises are currently attempting.
Both partnerships put Claude at the operational core of major Japanese corporations, not as a bolt-on feature. That makes Japan one of the more interesting active experiments in what deep enterprise AI integration actually looks like.
The Japanese Developer Ecosystem in 2026
Japan is often left out of the AI narrative that focuses on the US/UK corridor and China. That’s a mistake.
34.5% of Japanese companies are actively using generative AI as of 2026 — higher than most observers expected given Japan’s historically cautious approach to technology adoption. The country is driving adoption through a specific set of pressures that don’t apply in the same way to the US: an aging population, chronic labor shortages, and a manufacturing sector that needs automation at scale to remain competitive.
IDC projects Japan’s AI infrastructure spending at over $5.5 billion in 2026. That is not toy money, and it is concentrated in sectors — manufacturing, banking, logistics, healthcare — where AI that works reliably is more valuable than AI that is impressive but brittle.
Sakana AI is the most-watched Japanese AI startup internationally. Founded in 2023 by David Ha (formerly Google Brain) and Llion Jones (one of the original Transformer paper authors), Sakana has built a research program around “evolutionary” AI — using techniques analogous to biological selection to develop models rather than pure scale. They’re not building a Claude competitor; their work is complementary to foundation model ecosystems.
Rakuten released Rakuten AI 3.0 in early 2026 through the government-backed GENIAC (Generative AI Accelerator Challenge) program — Japan’s largest AI model developed by a private company through this initiative. Rakuten’s approach is explicitly bilingual and tuned for the Japanese market.
The GENIAC program itself (run by METI — Japan’s Ministry of Economy, Trade and Industry) has funded model development at Preferred Networks, Sansan, Turing, ABEJA, and NRI. These are not small or peripheral companies. Preferred Networks is one of the world’s leading robotics AI research organizations.
The pattern is: Japan has a serious, well-funded, institutionally-backed AI ecosystem that is oriented toward production applications in heavy industries and enterprise software, not toward consumer apps or content generation.
What Builders Outside Japan Should Watch For
Three things worth tracking from the Tokyo event:
The agent-in-enterprise case studies. Japan’s enterprise AI deployments are further along in some industrial sectors than most Western equivalents. What Hitachi is building for power generation and transportation is not a pilot — it’s production infrastructure. If Anthropic surfaces any detail about how these deployments are structured, it will be practically useful for anyone building agents for similar enterprise contexts.
Claude Code at the NEC scale. NEC deploying Claude to 30,000 engineers globally is one of the larger known Claude Code deployments. Any discussion of how engineering organizations at that scale are structuring Claude Code usage — what works, what doesn’t, how the tooling interacts with existing development pipelines — is applicable to any organization looking to do something similar.
The Agent SDK billing context. The June 15 billing split (programmatic Agent SDK usage moves to a separate credit pool) is active in eleven days. If Anthropic addresses how organizations are adapting production pipelines to the new billing structure, that’s time-sensitive for anyone running agentic workloads.
How to Watch
The June 10 main event livestream is available globally through Anthropic’s event registration. Sessions will be recorded and published after the event. The June 11 Extended event is not livestreamed but will also be recorded and published.
If you are in Tokyo and are an independent developer or early-stage founder, the Extended event on June 11 is worth registering for on the chance that spots are still available — it’s smaller and more hands-on than the main conference format.
The San Francisco and London sessions are already recorded and worth watching if you haven’t. “Beyond the Basics with Claude Code” from San Francisco in particular runs long but covers multi-agent coordination in detail that doesn’t exist in the documentation.
