Poliquant

HBX says that, fascinated by Tokyo's street culture at a young age, Junichi Sugita created the brand in early 2016. Sabukaru also says it was founded in 2016 and calls Sugita a Tokyo-born designer. This Thing Of Ours, in a 2021 new-brand post, names the founder as designer Jun Sugita and says he returned from working and studying at various fashion houses in Italy before setting up his own label. HBX and Sabukaru write the first name as Junichi, while This Thing Of Ours and EYE_C write Jun, and the sources do not reconcile the two forms.

A SEALSON product page names designers Jun Sugita and Kazuma Maruyama in its description of the collaboration jacket. We found no source that says who owns or funds the company.

EYE_C's Autumn/Winter 2025 article says outerwear is the label's speciality and lists utility vests, long coats, quilted down jackets and technical shell jackets, naming Pertex for waterproofing and Taion down products. For bottoms it describes lightweight synthetics and drawcords placed in unconventional spots so the wearer can change the shape of the trousers. Sabukaru lists baggy drawstring trousers, some in three-quarter length, multi-use jackets with connecting layers and overshirts with hidden pockets.

HBX says the label combines Japanese craftsmanship with European-style tailoring and fit, and quotes its motto as "POLITE - polish and sophisticated, PIQUANT- coquettish and tempting". EYE_C describes the Autumn/Winter 2025 collection as space-like uniforms reappropriated for urban and outdoor settings, with a function-driven approach and military and outdoor clothing references. Sabukaru calls the pieces unorthodox and rebellious and says the garments are built to handle Japan's harsh climate.

TAION's product page announces its first-ever collaboration with Poliquant, a 4-in-1 modular down system launching for the FW25 season. SEALSON sells a Poliquant x SEALSON versatile functions jacket with a utility bag, and describes Poliquant as a Tokyo-based brand that blends militaristic elements with Japanese heritage.

HBX has a Poliquant brand page and Foot District has a Poliquant collection. We could not read the brand's own website, so we cannot say whether it sells direct online.

Foot District listed a Linked Layer tee at 114 EUR, a Breathable Gradient hoodie at 322 EUR and cargo pants at 184 EUR, each with a higher regular price struck through (190, 585 and 335 EUR), and the page was showing a Mid Season Sale whose dates it did not state. Foot District also listed a rain jacket at 243 EUR (540 EUR struck through) and a Poliquant x TAION rain jacket at 343 EUR (685 EUR struck through). TAION listed its 4-in-1 modular down system at a regular price of $749.00, with no currency code shown, and SEALSON listed $308 and $440 USD for the jacket with utility bag, without saying which price is current. The prices are in different currencies and are not a like-for-like comparison. We checked these listings in October 2026.
