1. 長く甘い口づけを交わす

Romaji: nagaku amai kuchizuke o kawasu

Cultural Nuance: "Sharing a long, sweet kiss, immersing oneself in a luscious lingering afterglow as if time itself has stopped."

🗣 Japanese Insight: While the title uses the word "Seppun," the lyrics opt for the term "Kuchizuke."

• Seppun (接吻): A somewhat formal, direct, and weighty expression. It has an old-fashioned ring to it and, while passionate, carries a slightly objective nuance.

• Kuchizuke (口づけ): An extremely soft, literary, and poetic term. It is a romantic word that evokes traditional Japanese sensibilities.

By describing this "Kuchizuke" as something the two "Kawasu" (Exchange), the song depicts a mature intimacy where the feelings of both parties melt together as equals.

2. 深く果てしなくあなたを知りたい

Romaji: fukaku hateshinaku anata o shiritai

Cultural Nuance: "A desire to understand you down to the very depths of your soul, without limits or end."

🗣 Japanese Insight: The word "Shiritai" (to want to know) here goes beyond mere curiosity, expressing a desperate wish to touch the abyss of the other person's heart and their hidden loneliness. The addition of the word "Hateshinaku" (Endlessly) expresses a passion to bridge the spiritual distance that can never be fully closed, no matter how physically close two people become.

3. 枯れ葉色のtwilight

Romaji: karehairo no twilight

Cultural Nuance: "Watching the dusk turn to the color of withered leaves, trembling at a faint premonition that something is ending."

🗣 Japanese Insight: The unique color sense of describing the sunset as "Karehairo" (the color of withered leaves) gives this song a deep emotional resonance. The moment when dry, brownish colors begin to mix seems to emphasize a "faint loneliness" amidst the height of love, or the sorrowful realization that this happiness is not eternal.

By overlaying the transient image of "withering" onto a sophisticated urban landscape, the bittersweetness of adult love is brought to the forefront.

4. 子供のように無邪気に欲しくなる

Romaji: kodomo no yō ni mujaki ni hoshiku naru

Cultural Nuance: "Discarding all reason and pride, longing for you with the innocent raw honesty of a child."

🗣 Japanese Insight: In a song themed around an "adult kiss," words that are its polar opposite—"Kodomo" (Child) and "Mujaki" (Innocent)—are used symbolically. It seems to express the "hunger for naked affection" that everyone secretly harbors behind the facade of sophisticated adult behavior.

The pure, uncontrollable impulse that cannot be suppressed by logic is vividly conveyed through this single line.

5. 素肌 冷たすぎて苛立つ

Romaji: suhada / tsumeta sugite iradatsu

Cultural Nuance: "Feeling irritated by the physical coldness of skin to skin, fearing that your heart might be drifting far away."

🗣 Japanese Insight: Tajima's realistic writing shines in the choice of the word "Iradatsu" (to be irritated). When the skin you touch during a moment of intense passion feels unexpectedly cold, that physical temperature difference can trigger a sense of frustration, as if the partner's mind is elsewhere.

It captures a complex human psychology where love is so deep that even the slightest sensory misalignment turns into "irritation."

6. 永遠に独りでいることを知る

Romaji: eien ni hitori de iru koto o shiru

Cultural Nuance: "Realizing the cruel truth that no matter how tightly we embrace, humans are ultimately solitary beings."

🗣 Japanese Insight: This line is placed immediately after the passionate act described as "scorching play" (yakeru yō na tawamure). It portrays a certain peak of "physical soul music"—the realization that at the very moment of closest contact, one is thrust back into the reality of being an independent individual.

Acknowledging this "ultimate loneliness" while still choosing to love may be the very state of mind Tajima aimed for in this track.

7. 夜がすべて忘れさせる前に

Romaji: yoru ga subete wasuresaseru mae ni

Cultural Nuance: "Wishing to carve you deeply into my heart one last time before the night fades and washes away these memories."

🗣 Japanese Insight: "Yoru" (Night) is a magical time, but it is also a "device of oblivion" that hides reality and makes everything ambiguous. The act of "holding tightly" to etch the momentary passion into one's heart sounds like a desperate resistance against the fading form of love before reason returns with the day.

This conveys the urgency of wanting to make the temperature of this moment eternal before waking up from the dream.

🎤 Emotional Summary

ORIGINAL LOVE’s "Seppun -Kiss-" is more than just a passionate love song. It is a "cry of the soul" of a human being who, while harboring loneliness in a corner of the city, cannot help but seek out another, set to a sophisticated beat.

As Takao Tajima stated his desire to create "physical soul music," when we listen to this song, we can almost feel the temperature of someone's skin and the unique atmosphere as the night deepens.

No matter how deeply we love, we may ultimately be alone. Yet, we share a "long, sweet kiss" to share that very loneliness. When you accept that contradiction, this song transcends music and begins to shine like a scene from a film that walks alongside your life.
