Strong suit

What always amazes me when I see these suits of armour is how tiny their wearers must have been.

Thank you for the photo. Always glad to see a spotlight on historical and traditional items of cultural importance.

The level of craftsmanship is perfect.

Can't say I agree just by looking at the picture. Maybe you dropped into the department store for a look.?.

The armour does not look like a reproduction of a traditional armour. Knowing the artisans names would be revealing.

It would be nice to be able to read the information bottom left in the picture.

Just shy of ¥1,000,000 is slightly more expensive than one would pay for a polyester suit

My Japanese best friend and I were dressed in outfits like that by a professional costumer at Shiroishi Castle, last October, and got a lot of really cool photos from the session. I highly recommend the experience. Those costumes are heavy, too!

There is a rather good suit of Japanese armour in the Royal Collection, given as a diplomatic gift to James I by Tokugawa Hidetada in 1613.

Yes. A very famous example:

Armour 胴丸. This splendid and understated armour was sent to James I of England by Tokugawa Hidetada, third son of Tokugawa Ieyasu, who ruled as the second shōgun of the Tokugawa dynasty from 1605 to 1623.

It's fun to compare the two armours.

The one in the photo above is modern, but whoever generally put it together does not know how to display a set correctly.

Indeed. The 草摺 looks wrong for a start. And he looks like a geezer sitting on the train.
