Industrial spare parts for plant operators and workshops in Tokyo

When a measuring channel drops out, the regulator does not ask how long your quotation round took — so the sampling line is not a maintenance item but a permit condition with a clock on it. On shukchok its cooler goes into the same basket as the seal that fits it, price above the specification table.

What never stops on your site

Between the fault and the part you have hours, not weeks

An incineration line and a sewage works share the one feature that matters to a parts basket: their emission measurement runs continuously, and the sampling line ahead of the analyser is the piece that wears.

Lose one of them and the clock starts — and with it the quotation round. Five suppliers written to, queries about nominal size and material to wait for, three quotations to compare that mean different things. Two weeks for something that was manufactured long ago.

Against that stands shukchok: an open marketplace for industrial goods you can buy from and list on. One process instead of five, the price in yen at the position without a login, and underneath it material, operating limits and size as a table.

Two buyers, the same checkout

Who orders in Tokyo — and who could be selling here

The plant operator
Buys the sampling line: cooler, filter element, separator, seals. Predictable, recurring, and expensive in the minute it stands still. Purchase order number and cost centre travel through to the invoice, which is what counts when the cost lands on a plant budget.
The workshop in Ota-ku
More than 40 % of 3,584 businesses employ three people or fewer. No purchasing department, no framework contract, no vendor portal — and at the same time small-lot contract manufacturing that can put its own range in here without building a catalogue for it.

For suppliers

Your customers already order here — and the shelf space beside them costs nothing

Turn, mill or assemble small lots in Ota-ku and you know both halves of this page. As a buyer you take seals, connectors and pneumatic parts in many part numbers and small quantities, from several manufacturers in one basket and one ordering process. As a supplier you find the first half of this page describing the demand for your own range.

Neither a catalogue of your own nor a sales force is needed for that: you lodge the range and the prices, and the shop, the checkout, the invoicing and the customer contact are ours. The earning happens on the margin of a position that sells and nowhere else — no listing fee, no monthly fee, no manual approval. Manufacturer and supplier are named at every position, and who sells there — you or we — is visible before the order.
