Flat-fee Amazon Japan ad management

We watch your Amazon Japan ads, every single day.

Not just watching. We cut wasted spend the same day, push harder when buyers are active, and show you every move in a plain-English report each morning.

Flat fee, never tied to ad spend. From $150/mo

Sound familiar?

Your ads run 24 hours a day.
The hours you're not watching are where the money leaks.

TIME ZONES

Japan runs while you sleep

Your team is offline when the Japanese market is most active. Bids sit untouched during the hours that matter most.

LANGUAGE

The console is in Japanese

Keyword research, search terms and reports all assume Japanese fluency. It's hard to know what's really happening.

MONTHLY PDF

Your agency reports once a month

By the time you see the report, the spend is gone. Questions take days to answer across the time gap.

Those unwatched hours? Mihalo watches them for you.

The Mihalo promise

We watch, and we act.

Mihalo isn't a monitoring report you have to read. Our system watches your data around the clock and adjusts bids and budgets on the spot.

PROMISE1

Stop the wasted spend

We automatically lower bids on keywords and time slots that aren't converting, stopping the leak the same day it starts.

How: daily keyword-level performance pulls, with underperforming bids auto-adjusted.

PROMISE2

Capture the missed sales

We scale bids up during high-converting hours, and budget guardrails keep your ads from going dark in the afternoon and losing sales you never see.

How: hour-of-day bid scheduling plus a budget check every 30 minutes.

PROMISE3

Optimize bids, every day

We sync Amazon's suggested bids with live performance data daily and update at the keyword level — a cadence no human can match by hand.

How: daily sync of suggested bids, keyword and campaign performance into every bid.

STEP 1Grant access, that's itOur specialists handle the setup, structure and keyword selection for you.
STEP 2We watch and adjust 24/7Bids and budgets are monitored and moved in real time.
STEP 3A report every morningExactly what we did and why, in plain English, in your inbox.

And the fee is completely flat. We don't earn more when your ad spend grows —
so we're free to focus on cutting the waste.

Pricing

All published. All flat.

Your fee scales with the number of ad groups (campaigns) we run — not with your ad spend. A fair fee tied to the work. We recommend a one-campaign-per-ad-group structure for best performance.

FAQ

Clear up the doubts before you commit.

Do you guarantee results?

No — and be cautious of anyone who does. Instead, our daily report fully discloses what we did, and at day 90 we review Before/After in hard numbers.

Do you work with brands based outside Japan?

Yes. Most of our clients are overseas brands selling on Amazon Japan. We handle the Japanese-language console and the JST time zone so you don't have to.

Do you support marketplaces other than Amazon Japan?

Yes — the system works across Amazon marketplaces globally (US, EU, UK and more). That said, our deepest strength is the Japanese market, so brands entering or scaling in Japan get the most from us.

Is there a minimum term?

3 months on monthly billing, or 12 months on the annual plan. It's the minimum needed for the ads to learn and for us to prove the results.

How do you count ad groups (campaigns)?

By active SP/SB/SD ad groups. If one campaign has several ad groups, each counts. Paused ones don't. We recommend one campaign per ad group for best performance, and it's written into the contract.

Is account access secure?

We operate via Amazon's official OAuth authorization only. We never take your login ID or password (Amazon's terms prohibit it).

Can you handle Vendor Central (1P)?

Yes. Vendor (1P) operations are a strength of ours, with a proven track record for global brands.

Already with an agency — can we switch?

Yes. We audit your existing campaign structure and decide what to keep and what to rebuild during setup. We prepare the migration steps for you.

What happens if we cancel?

All campaigns stay in your account. We simply remove our access — your ad assets carry over untouched.

Free ad audit

See where your money is leaking — for free.

We'll audit your account for wasted spend and missed sales, and send you a report. Audit-only is welcome, no strings attached.

We'll send your audit report within 3 business days. No pushy sales.
