♥Save this maker

Trading as MARIKO TSUCHIYAMA LTD, registered at Companies House number 12402426.

What we have checked

Every brand here has to clear one test before it is listed at all: the company is a UK legal entity with real activity here. That is a question about the business, and it is deliberately not the same question as where any individual product is made.

• uk registered entity: Companies House record resolves, status active. This maker publishes no company number, so the record was matched on its registered postcode appearing at https://marikotsuchiyama.com/pages/privacy. Inferred by us (§3.3), not stated by the company. Source, checked 2026-08-29.
• uk hq: Registered office is a UK address: 109 Portland Road, Hove, BN3 5DP. This is the registered office, which is not necessarily where the company operates. Source, checked 2026-08-29.
• uk control: No majority shareholding traced outside the UK; controlled by Mariko Tsuchiyama. Source, checked 2026-10-06.

We have only checked company registration so far. Evidence of UK employment or a UK site is the next thing we intend to gather, and until we have it we say so on every product rather than implying it.

What they make

128 products listed. 121 state UK manufacture. 7 don't say where they are made, so neither do we.
