Kushina (くしな)

Sources Pronunciation guide

(Main) gender: Female
Pronunciation: kshee-nah [kɯ̟̥̀ᵝ.ɕí.nà]


Etymology and/or ways to write:
The first element of this name is written as either 櫛 (kushi) meaning “comb” or a combination of a ku kanji, like 久 meaning “long time,” 紅 meaning “crimson” or 来/來 meaning “to come, arrive,” and a shi kanji, such as 志 meaning “will, aim, goal” or 詩 meaning “poem.” As for the second element, any kanji with the (partial) reading na can be used, such as 奈, 菜 meaning “greens” or 凪 meaning “calm, lull.”
Kushina is included in part of the name of the mythological goddess Kushinadahime (also known as Kushiinadahime, Inadahime, etc.). There, the first part of her name is interpreted to come from the adjective 奇し (kushi) meaning “mysterious, wonderful, miraculous,” the second part, 稲田 (inada), referring to a rice field or paddy field.

Popularity:
Rarely used as a modern given name at just over 0.005% at its peak, it didn’t come into usage until at least the early 2010s, after Naruto character Uzumaki Kushina (whose name is speculated to be influenced from the mythological goddess), the mother of the titular character, first made her manga debut in January 2008 followed by her anime debut in ‘Naruto Shippūden’ in September 2009.

You may notice that Raito also transcribes to the English word light. It is indeed the case that, sometimes (especially among babies born from the Heisei period (1989-2019) onwards), kanji either related to the word or otherwise used for image conjuring are used, like 光 meaning “light; ray, beam, glow,” 月 meaning “moon,” 輝 meaning “brightness, brilliance” and 煌 meaning “glitter, sparkle.” While single kanji are used for this name, they are more likely to be combined with a to kanji or another kanji with some sort of connection to light, examples of the latter being 煌月, 輝星 and 月輝.

Popularity:
In use since at least the 1920s, much of its usage is concentrated on those born in the Heisei period onwards. In 1990, it was only given to around 0.005% of boys, remaining stable until the late 1990s when it began to rise in usage. By the late 2000s, well over 0.12% of boys received this name.

Satoshi (さとし)

Sources Pronunciation guide

(Main) gender: Male
Pronunciation: sah-to-shee [sá.tò̞.ɕì]


Etymology and/or ways to write:
This name usually stems from the classical adjective 聡し/敏し (satoshi) meaning “clever, smart; sharp, discerning,” however it’s also possible to connect Satoshi to the continuative form of the related verb 諭す (satosu) meaning “to admonish, persuade, warn.” Other kanji which expand on these are used, listing a few examples with meanings, 聖 meaning “sacred, holy,” 学 meaning “learning, study,” 達 meaning “reach, arrive, attain” and 暁 meaning “dawn, daybreak.” Some other kanji used are listed below:

智/知

They, alongside 里 meaning “village” and 郷 meaning “country(side),” can also be combined with a shi kanji, like 史 meaning “history,” 志 meaning “will, aim, goal,” 司 meaning “office” or 士, referring, in this case, to a man or samurai. For the first element, a sa kanji, e.g. 佐 meaning “help,” can be combined with a to kanji, e.g. 斗, referring to the Chinese constellation known as the Dipper. Another uncommon way to write this name is to combine a sa kanji with one that can be read as toshi, e.g. 寿 meaning “congratulations; longevity.”

Popularity:
By the latter half of the Meiji period (1868-1912), Satoshi had already started being placed in the bottom quarter of the top 100, which would last throughout the early 20th century. By that time, percentage levels didn’t exceed 0.4%. Fast forward to the early 1950s and it was ranked within the top 50, being given to well over 0.5% of boys born in that time period.
After stagnating for a little while, it rose again in the late 1950s which culminated in its first appearance within the top 10 by the early 1960s. At that point, percentage levels would exceed 1%, peaking in the late 1970s and early 1980s with over 1.4% of boys born back then receiving this name. By the late 1980s, it was already starting to drop down in popularity, falling below the top 20 and below 1%. Based on Baby Calendar rankings data and my preliminary 2014-9 names research, average percentage levels today have fallen to 0.05% or below.
