Drift Core Lab
Where rigorous science with real-world results.

THE LAB THAT ACTUALLY EXPLAINS ITSELF.

Drift Core Lab is an independent research and testing laboratory based in Hiroshima, Japan. We run material characterisation, environmental analysis, and prototype validation for manufacturers, startups, and research institutes who need data they can trust (and understand).

The story behind Drift Core Lab

The data was accurate. The communication was not.

Drift Core Lab opened in April 2019 in a converted industrial unit in Nishi Ward, Hiroshima. Dr. Kenji Murakami had spent the previous eight years as a senior materials analyst at a large testing conglomerate in Osaka, where he grew increasingly frustrated with the gap between what the instruments told him and what clients actually received in their reports. The data was accurate. The communication was not. He left in late 2018 with two colleagues, a shared lease on 180 square metres of floor space, and a fairly specific idea of what a testing lab should feel like to work with.

The first year was instructive in ways that were not always comfortable. The initial client roster was thin, the SEM unit broke down twice in the first six months, and the three founders spent more evenings than they would like to admit arguing about report templates. What came out of that period was a reporting format that has not changed much since: raw data on the left, plain-language interpretation on the right, corrective action notes at the back. Clients started referring other clients. By the end of 2020, the team had grown to six and the floor space had doubled.

Today Drift Core Lab runs a team of nine analysts and technicians, with instrumentation covering electron microscopy, ICP-OES, GC-MS, and a full mechanical testing suite. The client base spans automotive component suppliers, food packaging manufacturers, a handful of university research groups, and several early-stage hardware startups. Dr. Kenji Murakami still writes the interpretation section of every failure analysis report personally. He says it keeps him honest about what the data actually shows, as opposed to what a client might prefer it to show.

Standard test packages

BASIC MATERIAL ID PANEL

¥28,000

Elemental composition by EDX, hardness (Vickers, 5-point average), and a one-page summary report. Designed for incoming material verification when a supplier certificate is missing or suspect. Turnaround is 7 working days.

WATER QUALITY STARTER SCREEN

¥34,000

Tests for pH, turbidity, total dissolved solids, nitrates, and six heavy metals by ICP-OES. Suitable for well water, process water, or discharge monitoring at small facilities. Report includes comparison against Japanese drinking water standards (Suido-ho) where applicable.

INDOOR AIR VOC SCREEN

¥41,000

Passive sampler deployment (we post the sampler to you), laboratory GC-MS analysis for 13 target compounds including formaldehyde, toluene, and xylene, and a report benchmarked against MHLW indoor air guidelines. Used frequently by renovation contractors and building managers.

PROTOTYPE STRESS PACK

¥78,000

Three-point bend, tensile pull, and a 500-cycle fatigue run on up to three identical specimens. Produces a dataset suitable for early-stage design validation. Not a substitute for full JIS compliance testing, but a useful checkpoint before committing to tooling.

Why clients keep coming back

Transparent reporting

Every test result includes a plain-language interpretation section. You will never receive a 40-page PDF with no explanation of what it means for your product.

Turnaround you can plan around

Standard reports are delivered within 10 working days. Rush processing (5 days) is available for most material and environmental tests at a clearly stated surcharge.

Calibrated instruments, documented

All instruments are calibrated on a rolling 6-month schedule against JCSS-traceable standards. Calibration certificates are available on request for any test.

The hands behind it

Founder, Established since 2019

Dr. Kenji Murakami

Dr. Kenji Murakami studied materials science at Hiroshima University, graduating in 2007, and completed a doctorate in surface characterisation at Osaka University in 2011. He spent the following eight years as a senior analyst at a large testing firm in Osaka before founding Drift Core Lab in April 2019. He has co-authored three peer-reviewed papers on fatigue behaviour in aluminium alloys and is a registered member of the Japan Society for Testing Materials. Outside the lab, he cycles the Shimanami Kaido route most weekends when the weather cooperates and keeps a small vegetable garden that, by his own admission, produces more shiso than any household could reasonably use.

FAQ

Common questions

How do I submit a sample?

You can ship samples directly to our Hiroshima facility or, for fragile or large items, arrange a drop-off by appointment. We will send you a sample submission form after your initial consultation. The form asks for material type, quantity, and the specific tests you need, plus any relevant background on how the sample was produced or used.

Do you accept samples from outside Japan?

Yes. We receive samples from clients in South Korea, Taiwan, and occasionally Europe. International shipping is the client's responsibility, and we recommend using a tracked courier service. Import documentation requirements vary by material type, so contact us before shipping if you are unsure.

What happens if my sample fails a test?

We report the result as measured. If a sample does not meet the specification you provided, the report will note the deviation clearly and, where relevant, include a corrective action section. We do not adjust results or issue conditional passes. That is the point of using an independent lab.

Can I get a quote before submitting?

Yes, and we encourage it. Use the consultation form on this page or email us at lab@driftcorelab.com with a brief description of the material, the tests you need, and your timeline. We will respond within one business day with a scope outline and a fixed-price estimate.

Are your results accepted by Japanese regulatory bodies?

Our laboratory operates under a documented quality management system and all instruments are calibrated against JCSS-traceable standards. For specific regulatory submissions (e.g. Under the Chemical Substances Control Law or Food Sanitation Act), we recommend confirming with the relevant authority that third-party lab data from a non-accredited facility is acceptable for your specific application. We can advise on this during the consultation.
