Japanese work pants, and what they are not

Japanese work trousers

Japan has three well-known work trousers. Tobi trousers are worn by the construction workers who work at height. They balloon from the hip to below the knee and narrow sharply at the calf to tuck into boots. Samue trousers are the loose drawstring work clothes of Zen monks. Monpe are loose farm trousers gathered at the ankle. What they share is room where you bend and nothing loose where it could catch.

Japanese worker pants go by several names: tobi trousers for scaffolders, Japanese carpenter pants for site joiners, and Japanese construction pants for everyone else on the job.

Two pairs here take those shapes directly. The rest are practical cotton trousers built on the same priorities, room through the thigh and a hem kept out of the way.

Tobi and monpe

The Balloon Leg Tobi Trousers follow the scaffolder's cut, the classic tobi trouser. They run full through the thigh and knee, then gather in at the ankle, with buttons down the legs. The fabric is 80% polyester and 20% cotton. They come in one size, with a drawstring waist that adjusts from 66 to 115 cm.

The Monpe Balloon Pants are the farm version. With the tobi, they are the Japanese balloon pants of the range. Pleats at an elastic waist, a leg that balloons, and an ankle that narrows. They are polyester and they run small, so check the waist range before you order.

The cotton pairs

The four pairs below are 100% cotton pants men can work in all day. The Deconstructed Cargo Work Pants come in a wrinkle-resistant, structured weave that holds its shape through a full day and resists bagging at the knee and seat. Front pleats add structure at the waist, slash pockets keep the front clean, and the rise sits mid.

The Cotton Wide-Leg Cargo Pants are the heavy pair, 100% cotton at 570 g with thigh cargo pockets and structured front pleats. The leg is relaxed and wide all the way down.

Kotona is loose without being a harem cut, in 100% cotton woven to a textured surface with some grip. The pockets open from the top rather than the side seam, so nothing falls out when you sit, and the cuffed hem crops just above the ankle. The drawstring waist genuinely adjusts.

Sekino is cut wide and straight and stops at the calf, the shortest trouser we carry, in 100% cotton with an elastic waist and drawstring. It is a hot weather trouser. Air keeps moving because the hem is nowhere near the ankle. The Japanese Wide Leg Trousers are a cropped wide leg in stretch cotton with a mid waist.

How to wear them

The cropped pairs show the ankle, so shoes matter. A low sneaker or sandal works. A heavy boot fights a cropped hem. The tobi and monpe gather at the ankle, so they sit on a boot the way they do on site. Keep the top half plain and closer fitting.

For the pleated traditional cut see hakama pants. For the dropped-rise cuts see Japanese harem pants, for more volume baggy pants, and for everything together Japanese trousers. The history of each shape is in where to buy Japanese work pants.

Nikka pants and Japanese cargo pants

Nikka pants, or nikka trousers, are the third Japanese work cut: full through the thigh and gathered just below the knee, a shape and a name taken from knickerbockers. We do not carry a true nikka yet. The nearest here are the Wide Lantern Work Pants, which balloon and then gather at the ankle. For Japanese cargo pants, the Deconstructed Cargo Pant and the Pleated Cotton Cargo Pants are both cotton with front pleats.

Japanese workwear trousers, job by job

Japanese workwear pants grew out of three jobs. Japanese tobi pants come from scaffolders and steel erectors, and tobi work pants are still standard kit on Japanese building sites. Monpe come from the fields, and the nikka cut from the construction trades. Every pair of japanese workwear trousers here follows one of those lines, cut for wearing off the job site: the black balloon tobi trousers, the monpe balloon pants, the lantern work pants, the canvas carpenter pants and the cotton cargo pairs. Japan workwear runs to jackets too, and the noragi is the field jacket that went with monpe.

Sizing and care

Read the hip figure on each chart rather than the letter. The drawstring and elastic waists adjust but the hip does not. Every product page lists outside length, never an inseam. Each pair carries its own care guide. Kotona will not shrink at a cold wash.

If you are looking for white tobi pants, start with our balloon tobi in twill and our wide lantern work pants, both cut wide through the leg in the Japanese workwear tradition. White is one of the colours in this collection, alongside cream, apricot and khaki, so check each piece's colour options to find the pale tone you want.

Measurements come from the manufacturer's flat size table for each garment, converted to centimetres and mapped onto one size ladder. Available for 7 of the 10 garments here, last checked 2026-11-03. How we measure.

Frequently asked questions

What are Japanese work pants called?

The best known are tobi trousers, worn by construction workers who work at height, samue trousers worn by Zen monks for temple work, and monpe, loose farm trousers gathered at the ankle.

Do you sell tobi pants?

Yes. The Balloon Leg Tobi Trousers have the tobi shape, full through the thigh and knee and gathered at the ankle, in 80% polyester and 20% cotton, one size with a 66 to 115 cm drawstring waist. The Monpe Balloon Pants cover the farm version.

Which pairs are full length?

The Deconstructed Cargo Work Pants, the Cotton Wide-Leg Cargo Pants, the tobi and the monpe. Kotona and the Japanese Wide Leg Trousers are cropped, and Sekino stops at the calf.

How should they fit?

Size to the hip measurement on each chart. The drawstring and elastic waists adjust, but the hip is fixed. The monpe run small, so check the waist range first.

Are tobi pants the same as Japanese construction worker pants?

Yes. Tobi are the trousers Japanese construction workers and scaffolders wear, full through the thigh and narrow at the calf. In English they are also sold as Japanese work trousers or construction pants.

How long does delivery take?

Orders leave within 1 to 2 business days and usually arrive 5 to 9 business days after dispatch, with tracking. Shipping is free over $45, and returns are open for 30 days from delivery.

Why do Japanese construction workers wear tobi pants?

The pants take their name from tobi (鳶), Japan's scaffolders and steelworkers. The wide, ballooning legs leave room to crouch, climb and take high steps without pulling at the knee. Many workers say the loose cloth brushes an edge before the leg does, which is a small warning when working at height. The narrow ankle tucks into split-toe jika-tabi boots, and today the cut is also a sign of pride in the trade.

Do you ship to my country, and how much is it?

We ship to 33 countries: the 27 EU member states, the United Kingdom, Switzerland, Norway, Australia, Canada and the United States. Shipping is $7.90 USD to the US and Canada and $9.90 USD to Europe and Australia, free on orders over $45 USD, and you pay in your own currency at checkout. Duties and import fees, where they apply, are paid by the customer.

Can I return my order?

Yes, within 30 days of delivery if it is unworn and still tagged. EU customers also have the 14-day right of withdrawal. Return shipping is paid by you unless the item arrived faulty, damaged or wrong.

Is Amaji a Japanese brand?

No. Amaji is an online store for Japanese-style clothing with a US business address in New Castle, Delaware, and our work pants are made in China in traditional Japanese cuts.
