How to Judge a Social Media Agency in Japan

Apply the same seven tests to every agency here, including us.

1. Language ownership. Ask who writes the Japanese, who writes the English and who approves each. If nobody can be named, a translation step is probably doing the work.
2. Production. Who researches, scripts, films and edits? Ask how many hours your own team will spend each month.
3. What happens after the view. Does the agency build the offer, the automated messages, the LINE or email follow-up and the link into your customer database? Or does its job end when the video is published?
4. Proof close to your business. Ask for a campaign in a similar category, with dates. Keep views, followers, contacts and sales in separate columns.
5. AI-driven. Ask which steps the agency runs with AI or automation (research, scripts, editing, messaging, reporting), which steps people do, and who checks the output before your customers see it. Ask for the answer as a list of steps.
6. Measurement. Agree before launch what counts as success and when you will review it.
7. Ownership. Your accounts, footage and contact lists should stay yours when the contract ends.

How Hanami Social answers the AI-driven test: our scripts start as AI drafts, then every script goes through our team’s review and feedback rounds. The automated messages that capture contacts and deliver each offer are built for each client, and the follow-up runs on email, LINE or WhatsApp. Filming, editing and your approval stay with people. See how Hanami uses AI, step by step.

The agency checklist turns these into questions for a first call.

Hanami Social (publisher of this guide)

Fits brands that want short-form video to bring in inquiries, bookings and sales, in English, Japanese or both.

Hanami Social is a Tokyo-based social media agency. Its founder, Matt Hannan, 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).

The team handles the whole route from a stranger watching to a customer buying. That covers audience research, scripts, filming plans, editing and publishing, followed by the offer, the automated Instagram messages, the LINE, email or WhatsApp follow-up and the delivery of contacts into the client’s CRM. The client’s part can be one 1–3 hour filming session a month on a phone, or a managed creator can present instead.

How it uses AI. Hanami’s scripts start as AI drafts, then each one goes through the team’s review and feedback rounds before anyone films. When a viewer comments to request an offer, an automatic private message asks for their email or invites them to the client’s LINE account and delivers it; that message automation is built for each client. Hanami then tracks sales, booked calls and where potential customers drop off. The founder, a former Senior Software Engineer on the Instagram Reels Creation team at Meta, applies that experience to video publishing, performance measurement and automated sales funnels. Read how Hanami uses AI, step by step.
