One Love in Chinese / Japanese...

一份愛 means "one love."

一份愛 is not referring to a person but the emotion of love.

It's like saying "A piece of love" or "One unit of love." There's not a perfect way to express a singular love, which is probably what you were searching for.

一つの愛 is how to write "One Love" in Japanese.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

永恆的愛 is the best way to write "Eternal Love" in Chinese.

The first two characters mean eternal, eternally, everlasting, and/or perpetual.

The third character is a possessive article which sort of makes this selection mean "Love of the eternal kind."

The last character is "love."

This version is best if your audience is Chinese. We also have a Japanese version of eternal love.

永遠的愛 refers to love that will last forever.

The first two characters mean forever, eternal, eternity, perpetuity, immortality, and/or permanence.

The third character is a possessive article which sort of makes this selection mean "The forever kind of love."

The last character is "love."

永遠の愛 is a great way to write "Eternal Love" in Japanese.

The first two characters mean eternal, eternity, perpetuity, forever, immortality, and permanence.

The third character is a possessive article which sort of makes this selection mean "Love, of the eternal kind."

The last character is "love."

Cultural note: Most of the time, it is taboo to use the word "love" in Japanese. For instance, a Japanese man will say, "I like you," rather than, "I love you," to his spouse/girlfriend. However, this entry for eternal love is acceptable because of the way it is composed.

This entry is only appropriate if your audience is Japanese. We also have a Chinese version of this eternal love.

真実の愛 means "true love" or "genuine affection" in Japanese.

The first two Kanji mean true, real, genuine, or authentic.
The third Kanji is a connecting possessive article.
The last character is love or affection.

真愛 is literally "True Love" in Chinese.

The first character means "real," "true" and "genuine." The second character means "love" and "affection."

During the customization of your calligraphy wall scroll, there is a place to add an inscription. You might want that inscription to be your names in Chinese down the side of your wall scroll, or perhaps just below these two main characters (just $9 extra). A nice gift to celebrate an anniversary or marriage!

我心真愛 is a slightly poetic way to express this sentiment to someone.

The meaning is "My True Love" but the characters directly translate as "I/Me/My Heart/Mind True/Real Love."

Note that Chinese grammar and construction are different, so this sounds very eloquent and artsy in Chinese.
In Korean Hanja, the third character should be written differently, just let me know when you place your order if you want that version - it will still make sense in Chinese. This phrase makes sense in Korean but not commonly used.

These two characters mean, "Destiny that brings lovers together." It can also be translated technically as, "Predestined matrimonial affinity" (wow, talk about taking the romance out of this word - that was from the Oxford C-E dictionary).

Basically, this is talking about the fate (or karma) that brings a husband and wife together. I would translate this as "Together by fate" or "Joined by destiny" but in the context of marriage. You could use this for non-married lovers but the first character has a suggestion that this refers to those that are married.

靈魂伴侶 is the literal translation of "Soul Mates."

靈魂伴侶 is kind of the western way to express "soul mates" but translated into Chinese, Japanese Kanji, and old Korean Hanja.
The first two characters mean "soul" or "spirit."
The second two characters mean "mate," "companion" or "partner."

Although not the most common title, these characters have good meaning and will be received well in Chinese, Japanese, and Korean. It's a universal title!

精神伴侶 is title means "Spiritual Soul Mates." The first two characters mean "spiritual" or "soul." The second two characters mean "mates," "companions" or "partners."

精神伴侶 is more about the spiritual connection between partners rather than a "fate-brought-us-together" kind of soul mates.

Both halves of this title have meaning in Japanese but I've not yet confirmed that this is a commonly used title in Japan.

戀人 means lover, sweetheart or beloved in Chinese, Japanese Kanji, and old Korean Hanja.

This term is gender-neutral, so anyone can use it.

In modern Japan and China, the first character has been simplified. We suggest the traditional version, as shown above if your audience is Chinese or Korean. However, this generation of Japanese are more likely to recognize the simplified version.

魂の伴侶 is a Japanese-only title for soulmates.

魂 means soul, spirit, immortal soul (the part of you that lives beyond your physical body), or the conscious mind. In the Buddhist context, this is vijñāna or viññāṇa (consciousness, life force, or mind).

の is a possessive article that connects everything together here.

伴侶 means mates, companions, partners, spouses.

心の伴侶 is a Japanese-only title for soulmates.

心 means heart, soul, mind, core, or center. In ancient times, the heart was believed to be the mind, or center of your soul and being.

の is a possessive article that connects everything together here.

伴侶 means mates, companions, partners, spouses.

This Japanese version of soulmates is about two partners, coupled or joined by their hearts.
