Software Testing for Japanese Companies: Overlap, APPI, English

A Japanese company gets a strong live window with an offshore QA team in Bangladesh: Dhaka (UTC+6) is 3 hours behind Tokyo (UTC+9), so a 9-to-6 day shares about 6 hours, straight through the working day. Neither side changes its clocks, so the overlap is the same all year. The one honest limit is language: RAITHub delivers in English only. The main data rule to check is the APPI.

This guide is for Japanese founders, CTOs and QA leads whose teams work in English. RAITHub is a QA and software studio in Dhaka, with no Japanese office, delivering in English only, and is not SOC 2 or ISO 27001 certified. It builds and tests Japanese-language interfaces but does not write or translate Japanese copy. Read it as engineering and hiring guidance. Legal and data-protection points are general information; confirm them with a qualified Japanese adviser.

How many working hours do Japan and Dhaka share?

About 6, across most of the working day, and the same all year because neither Tokyo nor Dhaka observes daylight saving. With both sides on a 9:00 to 18:00 day:

Tokyo time (UTC+9)	Dhaka time (UTC+6)	What usually happens
09:00	06:00	Your morning; Dhaka is just before the working day
12:00–18:00	09:00–15:00	The ~6 shared hours: stand-up, demo, live bug triage
Tokyo afternoon	Dhaka midday	Most of QA can run live if you want it
Tokyo evening	Dhaka afternoon	Asynchronous; a written handoff lands for your next morning

Six shared hours is a wide window for offshore QA: your afternoon and the Dhaka morning line up, so most of the day can be live, with a written daily handoff closing the rest. For the wider model see offshore QA testing services; for another wide, single-timezone window see QA testing services in Saudi Arabia.

What does English-only delivery mean for a Japanese team?

It is the main thing to weigh. RAITHub works in English: test plans, defect tickets, CI output, release notes and live calls are all in English, and it does not write or translate Japanese copy. That fits teams that already run engineering in English, and is the wrong fit for a team that needs QA conducted in Japanese. What RAITHub does do is test a Japanese-language interface, even though the test documentation is in English:

• Rendering: Japanese strings, including full-width characters and ruby annotations where used, display, wrap and truncate correctly.
• Input: forms handle IME input, full-width and half-width characters, and Japanese name and address formats.
• Formats: dates, currency and sorting match the locale, including the Japanese era calendar where your product uses it.
• Mixed text: English product codes or URLs inside Japanese sentences order and wrap correctly.

This is a QA-service page, distinct from RAITHub's software-development guidance for Japan: here the subject is testing an existing or in-build product, in English.

What does the APPI expect before personal data leaves Japan?

Japan's Act on the Protection of Personal Information (APPI), overseen by the Personal Information Protection Commission (PPC), sets conditions on providing personal data to a third party in a foreign country, generally requiring the individual's consent to the overseas transfer, the recipient being in an adequacy-recognised country, or the recipient being bound to equivalent standards (Personal Information Protection Commission). For QA, the cleanest way to meet that is usually to avoid the transfer entirely:

• Test against synthetic data, not copies of real customers, so no personal data leaves Japan.
• Keep production data in your own Japan-region account, with testers deploying into it rather than hosting anything.
• Bind the recipient by contract to equivalent standards, as the APPI contemplates.
• Sign a DPA defining the testers' obligations and your instructions.

RAITHub makes no APPI "compliance" claim, and no vendor can take on your handling-operator obligations. What it does is sign DPAs, follow your controls, and design testing so personal data stays in your environment. This is general information; confirm your position with a qualified Japanese adviser and the PPC.

How big is the cost gap for a Japanese buyer?

Wide, and mostly in the rate. One 2026 QA outsourcing guide puts manual testing at $80 to $150 or more an hour in North America and $60 to $160 in Western Europe, against $8 to $55 in India and Southeast Asia, with automation 20 to 50% higher in every region (QA Madness 2026 rates). Freelance marketplaces sit lower: Upwork lists a median of $35 an hour for QA engineers (Upwork).

Option	Market rate (2026)	Overlap with your Tokyo day
Western agency (US or Europe)	$60 to $160/hr manual (QA Madness)	Partial, few hours
Freelancer or crowdtesting	Upwork median $35/hr for QA engineers	Varies, knowledge leaves each time
Offshore managed QA (Bangladesh)	$8 to $55/hr band region; quoted per scope	About 6 hours, plus async

Those are market figures, not RAITHub prices; RAITHub publishes no rates. A low rate times more hours or more rework is not a saving, so compare fixed quotes with scope and deliverables visible. See QA as a service pricing and in-house QA vs outsourced QA.

Where should the tests live?

In your repository, running in your CI, with bugs in your tracker. That is what separates a service you keep from hours you rent: if the automated suite lives on the vendor's machines, you lose it when the contract ends and cannot prove a release was tested. See QA gates for offshore teams and the test pyramid for SaaS.

Why RAITHub for QA in Japan?

• A wide live window, about 6 shared hours across the working day, all year, plus written daily handoffs.
• Japanese interfaces tested, not authored, covering rendering, IME input and locale formats; test documentation is in English.
• A managed service, not seats. RAITHub manages its own testers. It does not offer staff augmentation.
• Tests and IP you keep. Automated tests and CI configuration go in your repository, with IP assigned to you and an NDA as standard; DPAs are signed where personal data is involved.
• Counted suites as proof. Sundor Skin runs 530+ automated tests. TheSkinProof, the founder's own venture rather than a client, runs 750+.

When a Japanese company should not hire RAITHub for QA

• When QA must be conducted in Japanese. RAITHub delivers in English only and does not write or translate Japanese copy.
• When a customer or framework requires a SOC 2 or ISO 27001 certified vendor, or an accredited penetration test report. RAITHub holds neither certification and does OWASP-based testing, not certified pentests.
• When you need a legal accessibility certificate. A WCAG 2.2 audit reports issues and fixes but does not certify legal compliance; confirm with your adviser.
• When you want to manage the testers yourself. That is staff augmentation, which RAITHub does not offer.

How RAITHub would test this

• Scope: the journeys and roles that matter, the browsers and devices, the Japanese locale checks, and the test types across manual and exploratory, security and automation, API and performance.
• Rhythm: the wide Tokyo overlap for live triage, a written handoff every Dhaka working day, bugs in your tracker.
• Model: a monthly QA plan, a one-off audit or a dedicated team RAITHub manages and bills monthly.
• Contract: IP assignment, NDA, and a DPA where personal data is involved, designed so it stays in your Japan-region account.

Next step: a free 15-minute technical audit, then a written fixed quote. For the full service, see QA as a service. Ready? Ask for a QA plan or dedicated team quote.

Frequently asked questions

How many hours does a Japanese team share with Dhaka?

About 6, across most of the working day, with both sides on a 9:00 to 18:00 day. Dhaka is UTC+6 and Tokyo is UTC+9, and neither observes daylight saving, so the overlap is the same all year.

Does RAITHub deliver QA in Japanese?

No. RAITHub delivers in English only and does not write or translate Japanese copy. It does test your Japanese-language interface for correct rendering, IME input, locale formats and mixed text, with the test documentation written in English. It suits teams that already run engineering in English.

Can we send personal data to an offshore QA team under the APPI?

The APPI generally requires consent to an overseas transfer, an adequacy-recognised destination, or the recipient being bound to equivalent standards. The cleanest answer for QA is to test against synthetic data so no personal data leaves Japan. Confirm with a Japanese adviser and the PPC.

Is offshore QA cheaper than hiring in Japan?

On rates, clearly: Western manual QA runs $60 to $160 an hour or more, while offshore manual QA starts far lower. The total saving depends on hours and rework, so compare fixed quotes with the scope visible.

Will we keep the automated tests?

Yes, if they live in your repository and run in your CI from the start. RAITHub commits tests and CI configuration to your codebase and assigns the IP to you. Tests kept on a vendor's machines disappear when the contract does.

Does RAITHub have a Japanese office?

No. RAITHub is based in Dhaka, Bangladesh, works with Japanese clients remotely in English, and has no Japanese office. It is an offshore partner, not a nearshore one.
