Hello, I'm Konno from Classmethod's Sendai office.
Let me get straight to the point. On the night of Friday, September 18, 2026, we will be holding "DevelopersIO 2026 SENDAI" in Sendai.
And we're grateful to share that 31 out of 40 spots have already been reserved, leaving only 9 seats remaining. There are 11 days until the event.
Register here (free admission · limited seats remaining)
There are still seats available. In this article, I'll tell you "what kind of event this is," so if you're even a little curious, go ahead and secure your seat.
AI "hands-on experiences," in Sendai.
"I'm curious about AI, but I haven't really gotten around to trying it yet."
——If that sounds like you, this event is made exactly for you.
DevelopersIO 2026 SENDAI is an event where members of the Classmethod Group—which is promoting company-wide AI adoption and utilization—will <strong>deliver a series of "things we actually tried" in generative AI and cloud through LTs and sessions.</strong>
Rather than neatly organized, textbook-style talks, you'll take home the raw "we tried it" and "we messed up" stories from people who got their hands dirty in the field.
We're holding an "AI College Entrance Exam"
At this event, you can take an AI College Entrance Exam.
You'll solve problems on the spot and test your own AI proficiency. The key point is that we don't just give you a score and call it a day. We'll also explain the intent behind each question and walk you through the answers, so you'll leave with a new perspective like "Ah, so that's how you're supposed to think about it."
If you've ever wondered "Am I actually using AI properly?", come put yourself to the test.
Relax and enjoy yourself on a Friday night
The event kicks off at 18:00 on Friday.
We've scheduled it at a time when you can casually drop by after work. We're planning to provide drinks and light snacks. We hope you'll enjoy listening while having a drink and some nibbles on a Friday evening.
The venue is enspace, a 15-minute walk from Sendai Station and a 6-minute walk from the subway "Aobadori Ichibancho" station.
Kuranyann is coming 🐱
Classmethod's mascot "Kuranyann" will be visiting Sendai.
The Kuranyann in the thumbnail is a special zunda mochi version.
You can take photos together, so please come and say hello.
For those who are on the fence about attending
"I'm worried about feeling out of place going alone"
The majority of attendees are coming by themselves. This isn't a study group where everyone already knows each other, so coming alone won't make you stand out. In fact, it's completely normal.
"I'm worried I won't understand the talks if I'm not already doing AI seriously"
The content is designed so that even those who "haven't really gotten around to trying it yet" can take something home. It's not sharp, prerequisite-heavy talk—it's centered on real, down-to-earth "we tried it" experiences. Students and beginners are welcome too.
"I can't predict when I'll finish work"
Arriving late or leaving early is perfectly fine. It's okay if you don't make it for the opening, and leaving after just the sessions you're interested in is absolutely an option.
"I'm not great at networking events"
There is no formal networking session in the program. There will just be some casual time for those who want to chat after the event, so it's completely fine to listen to the sessions and head home.
