JAPEX is a small producer by global standards, and an explosion proof mobile phone for JAPEX sites in Japan serves a different pattern of work from a refinery. Japan Petroleum Exploration produces domestic oil and gas in Niigata, Yamagata and Akita and operates pipeline and LNG infrastructure that carries gas to customers. This page is for the HSE and telecoms people who decide what may be carried across a gas plant or a wellsite. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · IECEx certification programme in progress
JAPEX's fields are modest by global standards, and Japan's domestic upstream sector overall is small enough that the local ecosystem of Ex-rated equipment vendors accustomed to this specific niche is limited.
With most of Japan's oil and gas needs met by imports handled through refiners and LNG importers, JAPEX's own domestic fields represent a small, specialised segment where fewer vendors have built up local experience, an opening the IS-04Z1's certification programme is positioned to address directly.
JAPEX's producing fields, some with histories extending back decades, carry Zone 1 classified wellhead and gathering facilities, and Ex ib IIC T4 covers the hydrocarbon gas groups present.
JAPEX's production volumes are modest compared with the national oil companies covered elsewhere on this site, meaning device fleet decisions here involve smaller numbers of units, though the same certification rigour applies regardless of scale.
Some JAPEX fields have been producing for many decades, giving the company well-established local supplier and community relationships that new vendors need to work within.
EMM and MDM enrolment supports JAPEX managing a device fleet appropriately sized to its domestic field operations.
Japan's principal domestic upstream oil and gas producer, operating long-established onshore and offshore fields including in Niigata and Akita.
JAPEX supplies natural gas produced in Niigata, Yamagata and Akita prefectures, together with vaporised LNG received from overseas. Its 251 km Niigata to Sendai gas pipeline, completed in 1996, carries gas to city-gas utilities and large users across Tohoku. It also operates the Yufutsu field and a small LNG terminal in Hokkaido, and built the Soma LNG terminal in Shinchi, Fukushima Prefecture, which began operating in 2017. Wellheads, gas treatment plants, compressor stations and LNG facilities are the main classified areas. Some streams carry condensate or hydrogen sulphide, so the gas group and toxic gas questions need checking per site. The plant's classification drawing governs.
A technician driving to a wellsite in rural Niigata or Akita may work alone, in snow or rain, with patchy mobile coverage. A handset has to hold its checklist offline, store readings and synchronise when coverage returns.
Valve stations on a long gas pipeline are visited on a schedule. Four-constellation GNSS puts a coordinate on the record, and the 50 MP camera photographs a gauge or a corroded support.
Terminal crews work with cryogenic liquid, vaporisers and loading arms. The handset can replace a radio and a clipboard inside the classified area, subject to the scope of the certificate once issued.
No. The device is pre-launch, and IECEx certification is still in progress ahead of the Q4 2026 launch.
No, Japan imports the large majority of its oil and gas; JAPEX's domestic fields represent a small, specialised segment of the country's overall energy supply.
Fleet size is smaller, but the same certification and engineering-review rigour applies regardless of the number of units involved.
No, JAPEX is a separate, dedicated upstream producer distinct from Japan's downstream refiners and power generators, with its own procurement process.
JAPEX reports domestic gas production in Niigata, Yamagata and Akita prefectures, plus the Yufutsu field in Hokkaido. Ask the operator for its current list of producing sites.
Yes. Even a few dozen handsets benefit from an MDM console that enforces the same camera policy and app set at every wellsite, plant and terminal, and can lock a lost unit remotely.
Hydrogen sulphide is a toxic hazard handled by gas detection and procedure, separate from explosion protection. An Ex marking covers ignition risk, not toxic exposure, so personal gas monitors are still carried.
Ask JAPEX procurement and HSE teams directly for their supplier requirements. SAMS has not verified a specific programme and does not claim one.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Japan. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
