Festival Track ① Permanent Exhibition
■Generative AI Dress-Up Experience: JAWS Festa 2026 in AKITA Edition
The generative AI dress-up experience that even Jeff Barr tried at JAWS Days 2026 is back, upgraded, at JAWS Festa too!
Please enjoy the corner where you can change into all kinds of outfits unique to Akita using image generation AI × AWS.
Your transformed image can be downloaded, and you can also register it in everyone's memory album.
Please stop by and enjoy the simulated experience powered by generative AI.
■JAWS Festa 2026 in AKITA Edition! Development Tips Gachagacha
The Development Tips Gachagacha that was popular at JAWS DAYS 2026 is back once again!
It's an event where you can win Tips useful for development. Draw a hint or a spark of inspiration, and it's sure to be useful for something someday... maybe!?
You can also drop in your own original Tips, so please come with enthusiasm!
We'll also have winning lots prepared and are waiting for you. We hope you'll enjoy the gachagacha, renewed as an Akita version!
■JAWS Festa 2026 in AKITA Edition! Memory Upload
The Memory Upload that was a big hit at JAWS DAYS 2026 is coming to JAWS Festa 2026 in AKITA too!
Let's share everyone's wonderful memories and smiles! We also have goods to add to your memories, so feel free to use them.
We'll put up QR codes in the venue, so please access it from there.
■JAWS Festa 2026 in AKITA Exclusive Event! Tawara Stairs
We're holding the JAWS Festa 2026 in AKITA exclusive event "Tawara Stairs"!
It's a challenge event where you taste your gratitude for Akita's rice with your whole body. Carry a 5kg or 10kg tawara (rice bale) safely up the stairs of the venue.
You'll surely feel how much more substantial it is than it looks, and appreciate the rice that supports our daily meals.
Those who carry it well might win a nice prize! Participants and spectators alike, let's cheer together and get excited!
Rice Bale Onigiri-kun will cheer you on too!
The "Reiwa Edition AWS Karuta" and the tea party table "Jun-Kissa Same" were also held, but I ran out of time and couldn't go around to all of them…!
Festival Track ②
JAWS Festa 2026 in AKITA Edition Oogiri Competition
We're holding "AWS Oogiri," where laughter and love for the cloud intersect!
It's a participatory event where you answer prompts with inspiration and humor, themed on AWS services and the relatable moments of daily development and operations.
Not just depth of knowledge, but flexible thinking is the key to winning. Beginners and veterans alike, why not test your skills aiming for answers that make people groan with admiration?
Just listening to the answers as a spectator is also very welcome! There's no single correct answer. Let's liven up the venue with richly individual answers!
I couldn't participate, but "AWS BuilderCards Experience Session in JAWS FESTA 2026 in AKITA" and "Reiwa AWS Mahjong Tournament!" were also held.
Supporter Booths
The supporter booths are in the corridor of the 3F foyer, the same as the permanent exhibition.
This year, for people who were "not sure which booth to visit" or "want to talk with people from supporter companies," a supporter booth tour was also held.
The stuffed toy is so cute.
The opposite side of the booths is the flyer corner. Some companies also had novelties out.
In the flyer corner, there were also flyers with recruitment information for Classmethod Group.
Generative AI Dress-Up Experience 2026 AKITA Edition
This is the generative AI dress-up experience corner.
Let's enjoy dressing up in Akita-style outfits with AI!
You could choose from various outfits such as kimono, Akita dog, Namahage, and more.
I tried "Akita farmer's attire."
You scan the QR code, tap the displayed link, and long-press the image to save it.
The hat (?) didn't fit on well…
The screen is delivered via Amplify Hosting (CloudFront), the image generation request reaches Lambda, and Lambda calls the OpenAI API and saves the result to S3.
If you put an S3 presigned URL directly into a QR code, the URL becomes very long, so they put only a short ID in the QR code and, after scanning, obtain the presigned URL via Lambda, which keeps the URL short, I was told.
Memory Upload
This is the Memory Upload corner.
It's an album where participants upload photos taken at the venue, and the photos you post can be viewed right on the spot.
There was also a face-in-hole panel!
Here's the behind-the-scenes of Memory Upload.
- Screens and images are delivered via CloudFront, and processing such as posting and listing is handled by API Gateway and Lambda
- Photos are stored in S3, and photo information is stored in DynamoDB
- Photos that have finished being resized reach the browser via AppSync Events and are displayed as new arrivals
- Resize failures are notified to the organizers via SNS
I heard that Memory Upload has continued since JAWS FESTA 2025 in Kanazawa!
You can check the posted photos on your smartphone like this. Nice, isn't it?
Development Tips Gachagacha
This is the Development Tips Gachagacha corner.
It's the Akita version of the event that was popular at JAWS DAYS 2026.
When you turn the gachagacha, a development Tip comes out.
It also lists a "lucky item" and a "lucky person."
The paper I drew said, "Dissect costs with CUR 2.0. Identify the wasteful money-eating bugs and shout like a Namahage," and my lucky person was "a cost-conscious CTO."
Supplement: CUR 2.0
CUR 2.0 is a new format of the Cost and Usage Report (CUR), which outputs a detailed breakdown of your AWS charges. You export it with AWS Data Exports.
With the conventional CUR, the columns change every month depending on service usage, but with CUR 2.0 the columns are fixed. You can also select columns and filter rows with SQL.
Participants could also write a Tip and put it inside.
Tawara Stairs
As a "JAWS FESTA 2026 in AKITA exclusive event!", there was a Tawara Stairs corner.
It's an event where you carry a 5kg or 10kg tawara and climb all the way up the stairs without shaking it.
It was small, but the tawara packed with rice was much heavier than it looked.
A smartphone is fixed to the top of the rice bale with tape and detects the shaking.
You press a button, then lift the tawara and climb the stairs.
I climbed carrying the 5kg rice bale.
My score was 97.588 points.
Five items—quietness, calmness, smoothness, steadiness, and endurance—are displayed on a radar chart.
There was a QR code for registering participants' names, and I registered too and checked my ranking.
Wooo~ 2nd place!! Yes!!
I received rice as a prize! This year I'd already gotten 2 go of rice as a novelty, and getting another 4 go made me really happy. You can never have too much rice, since I'll eat it all!!
By the way, by the end of FESTA I had dropped to 5th place.
JAWS Festa 2026 in AKITA Edition Oogiri Competition
In Festival Track ②, an AWS-themed Oogiri competition was also being held.
It was really lively, but I was in a bit of a hurry and walked past quickly…! If you took part, please tell me later what everyone was getting so excited about.
Conclusion
The festival booths are fun for simply enjoying yourself and for interacting with other participants and staff. The festival space is permanent, so you can go anytime. Events such as Builder Cards tournaments are also held, so I think immersing yourself in the festival booths and interacting with lots of people on site is a way of enjoying JAWS FESTA that's truly unique to it.
