Your AV system shouldn’t be the reason your Tokyo office opens late
Conferencing, displays, and integrated audio for global companies building out offices in Japan — installed by engineers who already know which walls you’re allowed to touch.
The blindspot most global teams hit: the “koji” trap
Japanese commercial buildings split construction work into three legal categories. Most global AV vendors only know how to do one of them.
Building core work
Controlled entirely by the landlord. You can’t touch this.
B-koji
Infrastructure inside your space
Power routing, ceiling drilling, HVAC, fire alarms. The landlord picks the contractor — and the price.
C-koji
Visible fit-out
Mounting the screen, wiring the media rack. Easy. Anyone can quote this part.
Standard corporate AV packages are quoted on C-koji work. Then the team discovers the conference room table needs structural power, or the ceiling needs reinforcing for embedded microphones — and that’s B-koji. Now it requires a separate, marked-up negotiation with the landlord’s own contractor. Done wrong, the landlord can stop construction, or your fire and safety sign-off fails.
What it costs when nobody catches it early
Move-in dates slip by weeks while landlord contractor negotiations drag on
Budgets blow out on landlord-marked-up B-koji change orders nobody planned for
Fire and safety certification fails, halting the whole fit-out
We map the koji lines before you sign anything
We’ve negotiated with Tokyo landlords on enough projects to know exactly which fixtures cross into B-koji territory — before it shows up as a surprise change order. Our in-house, bilingual engineers scope the full job, including the landlord conversation, as one plan.
Licensed for both A-koji-adjacent and B-koji negotiation
Bilingual team — no translation gap with the landlord
One fixed quote, infrastructure costs included up front
An AV rollout that doesn’t bite you later
A move-in date you can promise leadership
Landlord touchpoints are resolved before the build starts, not discovered mid-build.
One number, no change-order surprises
B-koji costs are in the original quote, so the budget you present internally is the budget you spend.
One team accountable, not three pointing fingers
The same engineers handle infrastructure and the AV fit-out, so nothing falls in the gap between contractors.
You’re never the translation layer
We deal with the landlord and their contractor directly in Japanese, and report back to you in English.
The plan
1
Site & lease review
We read your lease and walk the space to flag every B-koji touchpoint before design starts.
2
Landlord coordination
We negotiate directly with the building’s contractor on your behalf, in Japanese.
3
Integrated install
One team handles infrastructure and fit-out together — no handoff gaps, no finger-pointing.
4
Sign-off & handover
Fire and safety certification confirmed before you move a single desk in.

FAQs
Do you handle the landlord negotiation, or just the AV install?
Both. We scope B-koji touchpoints during design and negotiate directly with the building’s contractor, so you’re not coordinating between two vendors who’ve never spoken.
How do you know which fixtures count as B-koji?
We review your lease and walk the site before any design work starts. Ceiling penetrations, structural power routing, and fire-system tie-ins are flagged immediately, not discovered mid-build.
Will this cost more than a standard AV quote?
Often less overall. Standard quotes leave out B-koji costs entirely, so they look cheaper until the landlord’s change order arrives. Ours includes it from the start.
What brands and platforms do you integrate?
Crestron, Cisco, and most major conferencing platforms. We design around what your global IT standard already requires.
Can you work with our existing facilities or IT team?
Yes. We typically run as the on-the-ground execution team reporting into your global IT or workplace lead, in English.
