June 3, 1615

Siege of Osaka

Tokugawa victory in the final Battle of Tennōji–Okayama

The battle remembered as Sanada Yukimura's last stand belongs to 3 June — but the name documented for him was Nobushige.

Keichō 20, fifth month, seventh day

On that day — 3 June 1615 — the Toyotomi field army fought Tokugawa Ieyasu's forces south of Osaka Castle in the final Battle of Tennōji–Okayama.

The Battle of Dōmyōji had been fought on the preceding Japanese-calendar day, 2 June, and the two are often collapsed into one anniversary. It pitted Gotō Mototsugu, Susukida Kanesuke, and Sanada Nobushige against Tokugawa commanders including Date Masamune and Katakura Shigenaga; Gotō and Susukida were killed there.

Three charges from Chausuyama

Sanada Nobushige — popularly called Yukimura in later literature — advanced from Chausuyama and made three assaults toward Ieyasu's headquarters before he was killed near Yasui Shrine.

Toyotomi Hideyori, head of the house, remained associated with the castle's defence rather than personally leading the attacks that later retellings assign to him.

The castle falls, the line ends

The Toyotomi field defence collapsed and Osaka Castle fell on the seventh day of the fifth month. Hideyori and his mother Yodo-dono died the following day, after an unsuccessful appeal for their lives.

The date, the locations, and the outcome are firm. The hour-by-hour reconstructions and the more colourful battlefield anecdotes come from later chronicles and do not carry the same weight.

What the sources leave uncertain

Japanese sources date Dōmyōji to Keichō 20, fifth month, sixth day and Tennōji to the seventh day. Converted to the Gregorian calendar, these are June 2 and June 3 respectively. Several English tertiary pages incorrectly place Dōmyōji on June 3 or June 5.
Precise hour-by-hour reconstructions and some colorful battlefield anecdotes derive from later chronicles and should not be presented with the same confidence as the date, locations and principal outcome.
