Tokyo National Museum rooms 15 and 16: arms and armor, 29 September to 20 December 2026

Open the Tokyo National Museum Honkan hall page for 29 September 2026, then again for 15 November 2026. Both print Arms and Armor of the Samurai | 12th-19th century in rooms 15 and 16 from Tuesday 29 September through Sunday 20 December. The suit named with that text is Armor (Gusoku) with a Two-Piece Cuirass and White Lacing, Edo period, 17th century, gift of Mr. Tokugawa Yoshihiro.

Swords move because steel and lacquer should not sit under lights all season. The summer 2026 page and item list 8429 cover 7 July to 27 September. Check tnm.jp for tickets, closing days, and the object list. These hall pages do not print a yen price.

Where the autumn dates are printed

Both pages put the gallery on the second floor of the Honkan, in Highlights of Japanese Art, and both print 29 September 2026 (Tue) through 20 December 2026 (Sun). December sits inside that window. The 15 November page, mid-run, still attaches the white-laced gusoku to the gallery text.

The museum's opening sentence is theirs, number and all: "The samurai ruled Japan for nearly 700 years, from the late 12th to the 19th century." Nearly 700 years is wall-text wording. The span in the room title is the one to repeat: late 12th century to the 19th.

Under that, the gallery's subject is swords, armor, and other military equipment. Color and material showed the owner's taste. Shape and construction reflected rank. Pieces left houses as heirlooms, diplomatic gifts, or donations to temples and shrines in prayer for victory.

The nearest major station is Ueno, on the JR Yamanote line and the subway. The hall pages print no walking time. On 15 November the tea gallery in room 14 runs 6 October to 20 December 2026, a second stop on the same floor.

Same title, different season

The sign on the door stays put while the published windows change. Compare them before you trust an undated photo.

Gusoku, a jacket-shaped torso, and white cord

Gusoku is the later full armor of the 16th and 17th centuries: a solid cuirass, shoulder guards, and a skirt of small plates over the hips and thighs. The hip plates are kusazuri. The thigh plates are haidate. The longer type history is on the samurai armor page. This suit is the later form, dated by the museum to the Edo period, 17th century.

The cuirass is two-piece, a ni-mai do. Front and back are separate, so you put it on like a jacket and close it. A one-piece domaru was stepped into and closed at the side. Domaru is older, and it is common in the Muromachi period. The split on a ni-mai do is about dressing speed and a tighter fit for infantry. Gusoku is the later full set around that torso.

White lacing is odoshi, the silk or leather cords that hold the small plates. Color helped units recognize each other across a field, and it showed who could pay for dyed silk. White cord shows dirt and sweat faster than black or navy, so keeping it clean meant washing or re-lacing. White lacing does not mean the wearer was morally pure.

Red lacing, on a gusoku in the summer rotation, reads as a strong unit color at a distance, and it hides stains less once the dye fades. White shows dirt at once. Helmet crests and color symbols are on the kabuto and armor symbolism pages.

What the donor line says

"Gift of Mr. Tokugawa Yoshihiro" names the person who gave the suit to the museum. That is a modern donation. The line leaves out Tokugawa Ieyasu, any named battle, and which Tokugawa the donor was.

A 17th-century gusoku can be parade armor from the Tokugawa peace, a gift, or a temple piece that later changed hands again. The Edo period is when many suits still looked martial and spent their years in storehouses and processions.

Heirloom, gift, or temple offering

A blade leaves a house for different reasons, and those reasons leave different paperwork. The autumn room mixes them.

• An heirloom stays in the family. Papers gather beside it: who inherited it, who had it polished, which house claimed the name.
• A diplomatic gift changes owners on purpose. The new house may remount the blade in its own fittings, so the hilt can be a century younger than the edge.
• A temple donation, hono, was an offering to a Buddhist temple or a Shinto shrine. Sometimes it followed a victory. Sometimes it was the prayer itself. The museum's line stresses prayer for victory in battle. The blade had already left the family for a temple or a shrine.

Those lives can share a shelf. Read the credit before you decide the shine means a battlefield.

What to look at in the sword case

Sori is the curve, the arc of the blade from the base toward the point. Hamon is the temper line, the bright boundary between the hard edge and the softer body, straight on some blades and a wave on others. The hilt is a separate object: it may be the original mounting, or a later one put on when lacquer failed or a new owner wanted different metal. The tang, nakago, is the bare steel under that hilt, and it is the usual place for a smith's signature. Cases often hide it.

The sword anatomy page lines those parts up, including tang and nakago as the same piece of steel. The famous swords page is how a name sticks after the fittings change. A later mount worn edge-up is the shape on the katana page.

Where else in Tokyo to see real pieces this season

If you want the smiths, leave the Honkan for another day. The Japanese Sword Museum in Ryogoku is showing Kotetsu and Tsuda Sukehiro from 24 October to 20 December 2026. Plan that as its own visit. Rooms 15 and 16 are the national collection's equipment, with the white-laced gusoku as the suit the autumn hall pages name. Dates and the two smiths are on the Kotetsu and Sukehiro page. A wider map of real armor and swords in Japan is on samurai museums in Japan.
