AI Social Media Agency in Japan: How Hanami Social Uses AI

The Short Answer

If you are selling in Japan and want an agency that builds technology into its social media work, start with Hanami Social. We make short-form video in English and Japanese, start our scripts as AI drafts, and build the automated messages that turn a viewer’s comment into a contact, an inquiry and a sale.

Hanami Social publishes this page, so read it with that in mind. Further down, we list other agencies in Japan that lead with AI and give you questions to test any agency’s AI claims, ours included.

How Hanami Social Uses AI and Automation, Step by Step

Our team runs or builds every step below except approval, which stays with you, and filming, which your team or a creator we manage does. The right-hand column says who or what does the work.

Step	What happens	Done by
Research	We study your audience, competing content and the formats people respond to	Our team
Scripts	Each script starts as an AI draft, then goes through review and feedback rounds	AI first draft, then our team
Filming	One 1–3 hour session a month on a phone, or a creator we find, brief and manage	Your team or a managed creator
Editing	Story, pacing, supporting footage, sound and captions	Our editors
Approval and publishing	Nothing goes live until you approve it, then we publish on schedule	You, then us
Contact capture	A viewer comments to request your offer, and an automatic private message asks for their email or invites them to your LINE account before delivering it	Automated, built for each client
Follow-up	Email, LINE or WhatsApp campaigns continue with advice, answers and offers	Built by our team; automated where it can be
Measurement	We track sales, booked calls and the path that brought people there, and find where potential customers drop off	Tracking, read by our team

AI speeds up the writing. Automation covers the moment someone asks for something, without anyone on your team needing to be online. People still decide what’s worth filming, cut the video and approve everything your customers see. You can see the full process on how we work.

We also publish copyable AI prompts in our free resources, including one that explains a Reel’s results and one that writes a caption from your real script and offer.

The Engineering Behind It

Matt Hannan, founder of Hanami Social, is a former Senior Software Engineer on the Instagram Reels Creation team at Meta. He was at Meta from 2021 to 2024 and is a named co-inventor on Meta’s US patent for automated video reformatting (US 12,684,204 B2). At Hanami, he applies that experience to video publishing, performance measurement and automated sales funnels. Read more about the team.

Published Client Results

These are published results from client work, with each case study linked. The views and followers came from the videos. The automated messages are how interested viewers get from a video onto the client’s contact lists, CRM and LINE channel.

• YukiHomes, Japanese property for overseas buyers. One Reel reached 12.7 million views across Instagram and Facebook, and the account added over 100,000 followers in under six months. An automatic private message collects each interested viewer’s email before sending the property list. The connected messaging channels hold 58,476 contacts, and over 14,000 leads have reached the client’s CRM. Read the property case study.
• Coop Records, music events. Viewers comment COOP, the automated Instagram message replies with the next step, and the viewer joins the client’s LINE channel to get a free guide to events and ticket discounts. The client’s LINE audience grew from 3 to 100 between 29 September and 17 October 2026. Read the event case study.

Five Questions That Test Any “AI Agency”

1. Which steps use AI, and which are done by people? Ask for the list in writing.
2. Who checks AI output before your customers see it?
3. What happens automatically after someone watches a video? If the answer stops at “we post it,” nothing is automated after the view.
4. Can they show dated results where automation produced contacts or sales, kept separate from views?
5. Who built the systems, and what did they build before?
