Hakari Kinji is one of the best sorcerer in Jujutsu Kaisen.
When Hakari expands his domain, he makes a unique hand sign.
There is a close relationship between this hand sign and his cursed technique.
In this article, a native Japanese writer explained Hakari’s Domain Expansion, the original source of its hand sign, and its meaning including Japanese backgrounds.
Effect of Idle Death Gamble
Idle Death Gamble is a domain with a gambling motif.
Every time Hakari activates his techanique inside the domain, he enters the jackpot lottery.
And if Hakari hits the jackpot, he can obtain a bonus.
In addition, the odds of hitting the jackpot of Idle Death Gamble are quite low at 1/239.
Instead of the low of the odds, the jackpot bonus is super powerful: 4 minutes and 11 seconds of unlimited cursed energy and immortality with fully automatic reverse cursed technique.
Hand Sign
When Hakari activates the Idle Death Gamble, he makes a unique hand sign.
In addtion, Hakari cannot expand the domain without the hand sign, because Kashimo took Hakari’s arm to prevent the Domain Expansion.
So, this hand sign must have an important meaning.
I will explain below.
Benzaiten
The original source of Hakari’s hand sign must be Benzaiten(弁財天, 弁才天).
Benzaiten is one of the Seven Lucky Gods and represent music, speech, wealth, wisdom, and longevity.
Benzaiten (wikipedia)
Benzaiten (shinjitai: 弁才天 or 弁財天; kyūjitai: 辯才天, 辨才天, or 辨財天, lit. “goddess of eloquence”), also simply known as Benten (shinjitai: 弁天; kyūjitai: 辯天 / 辨天), is a Japanese Buddhist goddess who originated mainly from Saraswati, the Hindu goddess of speech, the arts, and learning, with certain traits deriving from the warrior goddess Durga. Worship of Benzaiten arrived in Japan during the sixth through eighth centuries, mainly via Classical Chinese translations of the Golden Light Sutra (Sanskrit: Suvarṇaprabhāsa Sūtra), which has a section devoted to her.
And what this Benzaiten represents must be related to the effects of the Hakari’s domain.
Relation between Benzaiten and Hakari’s domain
・Music → Music during the jackpot bonus
・Wealth → The jackpot bonus
・Longevity → Immortality with the jackpot bonus
After Hakari hits the jackpot, a music begins playing for 4 minutes and 11 seconds.
This music may be based on what Benzaiten represents.
And, the meanings of kanji 弁財天 includes money and wealth, which would be related to the gambling of Hakari’s domain.
In addtion, the meanings of kanji 秤金次 (Kinji Hakari) includes money and gold.
Also, Benzaiten represents longevity, which would be related to the immortality of the jackpot bonus.
As described above, there must be a deep relationship between the effect of Hakari’s domain expansion and the what the hand sign represents.
