Kōdai-in (高台院) (died October 17, 1624), formerly known as Nene (ねね), One (おね), Nei (ねい), was an aristocrat and Buddhist nun, founder of the temple Kōdai-ji in Kyoto, Japan.

As the matriarch figure of the Toyotomi clan, she led all diplomatic affairs that had to do with the imperial court, and monitored the daimyos' families who were being held hostage at Osaka Castle.

She was adopted by her maternal uncle Asano Nagakatsu, a descendant of the Toki clan, of Minamoto no Yorimitsu (944-1021), and the Emperor Seiwa (850-881).

Hideyoshi did this after his invasion of Sassa Narimasa's territory in Japan's Hokuriku region and after his campaign against the Shimazu clan.

Nene had a captivating and gentle personality, so she gained the respect of many; she helped and housed many women related to the Western Army (commanded by Ishida Mitsunari) after the Battle of Sekigahara.

[2] After her death in 1624 and burial within the temple compound of Kodai-ji, she was posthumously given the name of Hikari no Tenshi or "Angel of Light".

[citation needed] The life of this prominent resident of Kyoto is still commemorated in a short street which bears her name.

Nene's Street (ねねの道, Nene-no-Michi) remains lined with structures built in traditional Kyoto style.

Nene-no-Michi is located in Higashiyama Ward in eastern Kyoto near Kōdai-ji, Maruyama Park and Yasaka Shrine.
