Shower Head Supplier for Japan

Fitment and thread standards in Japan

Current Japanese hand showers and hoses commonly use a G1/2 connection, which matches ZHONGHE's default, but Japan is the market where the installed base decides the packing list. Older faucets from different Japanese makers carry maker-specific fittings, and a head sold at retail is therefore normally packed with a small adapter set so the buyer can fit it whatever is on the wall. The S/G/K/M adapters cover common legacy sizes: S is M22.1 x 1.5, G is M21.3 x 1.5, K is M21.5 x 2 and M is M22.1 x 1.75.

For an OEM programme, list the faucet families the product has to serve, state whether the adapter set is in the box or sold separately, and agree the compatibility wording for the manual. Japanese listings are read closely, so the compatibility statement is written per project rather than copied from another market.

Regulations, certifications and import documents

Japan's framework has two layers. JIS standards cover faucet fittings and related components, and the Water Supply Act framework sets performance and material requirements for devices connected directly to the supply pipework, with leaching test methods commonly cited for materials in contact with drinking water. A hand shower fitted downstream of a mixing faucet is commonly treated differently from a device plumbed straight into the supply, so the route depends on the product configuration. Confirm the applicable position with your customs broker or importer.

ZHONGHE prepares the underlying evidence: component and media test reports, flow figures at a stated pressure, a 0.5MPa leak check, and a 100% water test of about 10 to 15 seconds on every unit, with third-party testing arranged per project. Certified options are available on request.

What sells in Japan: water conditions, channels and product fit

Japanese tap water is soft and carries maintained residual chlorine right to the tap, which explains the shape of the market: the premium shelf is built on 塩素除去 and 浄水 cartridges, on 節水 percentages, and on ファインバブル constructions, not on limescale. ZHONGHE's activated carbon fiber media has shown 99.5% free-chlorine removal at the start of flow in SGS testing and 90.6% after 5 tons of water, and those two figures with their conditions are the honest way to write a Japanese listing. Skin, hair and health claims are not supported by the factory.

Product expectations are exacting in ways that cost money if they are found late: a stop button that feels crisp, a nozzle plate with no flash, plating with no orange peel, a hose that does not kink, and packaging that survives a courier without a scuff. Japanese buyers usually run a sample approval round before production, and the factory plans for it. The Japan market itself, including Japanese-language content and Japan-specific retail support, is served from zhonghejapan.com; this page is for buyers sourcing from outside Japan.

Logistics, terms and how to start

Tokyo, Yokohama, Osaka, Kobe and Nagoya are all served directly, and the run is approximately 3 to 7 days by sea from Ningbo-Zhoushan, which is short enough that Japanese programmes can work on smaller, more frequent shipments than most markets. Quotations are FOB Ningbo by default, with other Incoterms on request, and heads, hoses, holders, adapters and cartridges consolidate on one invoice.

MOQ discussions start from about 2,000 units per model, with custom packaging from the same level; production on existing models runs about 30 days as a guide, and a new design adds about 15 days of appearance design, 15 days of structure design and about 60 days of mold making. The online catalog shows 115 photo-documented models and the full range goes beyond them.
