Love and Relationships in Chinese / Japanese...

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.

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 is not commonly used.

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.

愛は全てを完全に結ぶ帯である is a Japanese phrase that suggests we (or a couple) are bound together by love.

I searched the web and found all of these English translation variations for this phrase:

Have love; The only way in which you may be completely joined together.

Love is the sash that perfectly binds us together.

Love is what binds us together

Love binds all things together in perfect unity.

This same Japanese phrase is used as part of Colossians 3:14 in at least one version of the Japanese Bible.

A few Biblical versions include:

...Charity, which is the bond of perfectness. (KJV)

...Love, which binds them all together in perfect unity. (NIV)

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

This proverb, 爱花连盆爱爱女疼女婿, literally translates as “If one loves a flower, [one will] love its pot; [if one really] loves [one's] daughter, [one will also] love [one's] son-in-law.”

Figuratively, is similar to the English proverbs:
Love me, love my dog.
Love for a person extends even to the crows on his roof.

力愛不二 is a proverb that literally means:
“Strength [and] Love [are] Not Two [separate ideas/concepts/things].”

You'll find this proverb translated from Japanese to English as:
Love and strength are not separate.
Power and love are indivisible.
Strength and love in harmony.
Strength and love stand together.

Old Japanese grammar is quite different than English, and so this proverb says a lot within the brevity of just 4 characters. If you just read these characters directly as “Strength Love Not Two,” you'd probably miss the real meaning.

According to the Swedish Shorinji Kempo Federation, this is the second characteristic of Shorinji Kempo.

This post really explains the concept best in my opinion: Bushido by MS: Riki Ai Fu Ni, which states: "Riki Ai Funi" is the philosophy that power (Riki) and love (Ai) are indivisible. More concretely, a person, who is powerful but does not have love, cannot control and misuse his/her power; on the other hand, a person, who has loved ones but is not powerful enough, cannot protect himself/herself nor loved ones.

相愛互敬 is a nice way to say “Love and Respect” in Chinese.

This proverb is about the mutual exchange of love and respect within a good relationship.

The first two characters create a word that means “to love each other” or “mutual love.”

The third character means mutual, interlocking, or in some contexts, “to dovetail” (as in how joints are made in fine furniture).

The last character means “to respect,” “to venerate,” “to salute,” “reverence,” or simply “respect.”

爱在心里狠在面皮 literally translates as “Love [your] children in [your] heart, [but] be stern [with them] in [your] manner.”

This is a little like saying “Love your child but don't spare the switch.”

誰言寸草心報得三春暉 is the last line of a famous poem. It is perceived as a tribute or ode to your parents or mother from a child or children that have left home.

The poem was written by Meng Jiao during the Tang Dynasty (about 1200 years ago). The Chinese title is “You Zi Yin” which means “The Traveler's Recite.”

The last line as shown here speaks of the generous and warm spring sunlight which gives the grass far beyond what the little grass can could ever give back (except perhaps by showing its lovely green leaves and flourishing). The metaphor is that the sun is your mother or parents, and you are the grass. Your parents raise you and give you all the love and care you need to prepare you for the world. A debt that you can never repay, nor is repayment expected.

The first part of the poem (not written in the characters to the left) suggests that the thread in a loving mother's hands is the shirt of her traveling offspring. Vigorously sewing while wishing them to come back sooner than they left.
...This part is really hard to translate into English that makes any sense but maybe you get the idea. We are talking about a poem that is so old that many Chinese people would have trouble reading it (as if it was the King James Version of Chinese).

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

This 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.

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 here.

伴侶 means mates, companions, partners, and spouses.

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

靈魂伴侶 is the literal translation of “Soul Mates.”

This 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!

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 here.

伴侶 means mates, companions, partners, and spouses.

永遠愛在一起 is “together forever in love” in Chinese.

It's a nice phrase if you're a couple who plans to stay together and make your love last as long as you live.

心の姉妹 is “heart of sisters,” “soul sisters,” or “sisters of the heart.”

This can be used for actual sisters to celebrate the heartfelt love they feel.

It can even be used by two women who feel a connection as if they are sisters.

愛別離苦 is a Buddhist term that refers to “the pain of separation from loved ones,” or “the suffering of being separated from those whom one loves.”

If you translate each character separately, you get, “love(s) separated [and] departed [yields] pain.”

The pain character can also be defined as anguish; suffering; distress; anxiety; worry; trouble; difficulty; hardship; bitterness; to suffer; anguish; distress; anxiety; worry; trouble; difficulty; bitterness; unhappiness; or misery.

破鏡重圓 is about a husband and wife who were separated and reunited.

About 1500 years ago in China, there lived a beautiful princess named Le Chang. She and her husband Xu De Yan loved each other very much. But when the army of the Sui Dynasty was about to attack their kingdom, disposed of all of their worldly possessions and prepared to flee into exile.

They knew that in the chaos, they might lose track of each other, so the one possession they kept was a bronze mirror which is a symbol of unity for a husband and wife. They broke the mirror into two pieces, and each of them kept half of the mirror. They decided that if separated, they would try to meet at the fair during the 15th day of the first lunar month (which is the lantern festival). Unfortunately, the occupation was brutal, and the princess was forced to become the mistress of the new commissioner of the territory, Yang Su.

At the Lantern Festival the next year, the husband came to the fair to search for his wife. He carried with him his half of the mirror. As he walked through the fair, he saw the other half of the mirror for sale at a junk market by a servant of the commissioner. The husband recognized his wife's half of the mirror immediately, and tears rolled down his face as he was told by the servant about the bitter and loveless life that the princess had endured.

As his tears dripped onto the mirror, the husband scratched a poem into his wife's half of the mirror:

You left me with the severed mirror,
The mirror has returned, but absent are you,
As I gaze in the mirror, I seek your face,
I see the moon, but as for you, I see not a trace.

The servant brought the inscribed half of the mirror back to the princess. For many days, the princess could not stop crying when she found that her husband was alive and still loved her.

Commissioner Yang Su, becoming aware of this saga, realized that he could never obtain the princess's love. He sent for the husband and allowed them to reunite.

This proverb, 破鏡重圓, is now used to describe a couple who has been torn apart for some reason (usually divorce) but have come back together (or remarried).
It seems to be more common these days in America for divorced couples to reconcile and get married to each other again. This will be a great gift if you know someone who is about to remarry their ex.

永遠の友 is a Japanese phrase about eternal friendship.

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 “friend” or “Friendship.”

残心 is a Japanese Kanji word meaning: continued alertness; unrelaxed alertness; remaining on one's guard; lingering mind, and being prepared for a counterstrike. This context is used in martial arts, which is probably why you are looking up this word.

In archery and golf, it can be the follow-through.

In the context of love and relationships, it can be lingering affection, attachment, regret, regrets, or reluctance.
