Yang Release

The elemental techniques, based on the physical energy that governs life, are used to breathe life into form. When Minato Namikaze sealed the Nine-Tails into Naruto, he sealed the Yang half of its chakra into Naruto using the Eight Trigrams Sealing Style. When Naruto transformed into his controlled jinchūriki form, Yamato's Wood Release totems reacted to the Yang chakra's life-giving nature, and they transformed into full grown trees. When combined with Yin Release, it allows the use of Yin-Yang Release.
