A guide for this piece: about $46, based on the 10% US charge on the declared value of goods made in Japan.
The final figure is set by US Customs and depends on where the piece was made and the kind of object it is. Many antiques over a century old carry no ordinary duty; most jewellery and leather goods add a single-digit rate.
With EMS, any charge is collected by your postal service on delivery. For pieces of significant value we can often arrange duties prepaid before dispatch.

A zip-front denim blouson from the in-stru(men-tal). line of MIHARA YASUHIRO, reference I08BL011: slubbed black cotton denim, a grey chambray lining and a deliberately unruly, oversized cut. Marked size 46.
The Piece
At first glance it reads as a workwear blouson: point collar, full zip, a square chest pocket and two deep patch pockets low on the front. Look again and the proportions shift. The body is wide and cropped, the hem curves away at the back, and the sleeves are gathered with extra fabric that folds and bunches at the elbows, so the jacket hangs with a crumpled, sculptural volume.
The denim is a slubbed black cotton with a heathered, almost tweed-like surface, lined in a lighter grey chambray that shows at the open front and hem. A woven in-stru(men-tal). label sits inside the neck, and the line's printed patch label is stitched over the lower right pocket. Buttoned cuffs close with metal shanks.
