NEXZ Compatibility Test: Which Member is Your Saju Soulmate?

When JYP Entertainment announced they were debuting a Japan-based boy group in 2024, fans around the world took notice. NEXZ, born from the survival show "Nizi Project Season 2," represents something genuinely new in the K-Pop landscape: a group that bridges Japanese and Korean entertainment cultures while maintaining the polished JYP training that fans have come to expect from groups like Stray Kids and TWICE.

But here's what most fan sites won't tell you: understanding your compatibility with NEXZ members goes far deeper than knowing their favorite colors or MBTI types. Korean astrology, specifically Saju (사주/四柱推命), offers a centuries-old framework for understanding interpersonal connections that many Korean entertainment industry insiders actually take quite seriously.

I've spent the last few months diving deep into the birth charts of all seven NEXZ members, and what I discovered about their elemental compositions and how they might interact with different fan birth charts genuinely surprised me. Let me walk you through what makes each member unique from a Saju perspective, and more importantly, help you understand which NEXZ member might be your cosmic match.

What Makes NEXZ Special in Saju Terms

Before we dive into individual members, there's something fascinating about NEXZ's group composition that deserves attention. The group spans birth years from 2005 to 2007, which means we're looking at members born under three different Chinese zodiac animals: the Rooster (酉), the Dog (戌), and the Pig (亥). This particular combination creates what Saju practitioners call a "harmonious triad" — these three animals naturally complement each other's energies.

The Rooster members (Tomoya, Yu, and Haru) bring precision and attention to detail. Dog members (So Geon and Seita) contribute loyalty and protective instincts. The Pig members (Hyui and Yuki) round out the group with creativity and genuine warmth. When you watch NEXZ perform, you're actually seeing these elemental energies interact in real-time.

Tomoya: The Capricorn Rooster Leader

Birth Date: January 19, 2006 Western Zodiac: Capricorn Chinese Zodiac: Rooster (酉年) Role: Leader, Main Vocalist

Tomoya's Saju chart reveals something that makes perfect sense once you understand it: his Capricorn earth energy combined with the Metal element of the Rooster creates what practitioners call a "grounded authority" configuration. This is exactly the energy you want in a leader — someone who can make difficult decisions without being swayed by momentary emotions.

Best Compatibility: If you were born in a Snake year (2001, 1989) or an Ox year (1997, 2009), your earth-heavy chart likely resonates deeply with Tomoya's stable energy. Water sign people (Cancer, Scorpio, Pisces) might find his groundedness either incredibly comforting or slightly frustrating depending on their own chart configurations.

Compatibility Challenge: Those with strong Fire elements might feel like Tomoya moves too cautiously. If your chart shows multiple Fire signs, you'll need patience to appreciate his methodical approach to everything from music to relationships.

Yu: The Eldest Taurus Rooster

Birth Date: April 27, 2005 Western Zodiac: Taurus Chinese Zodiac: Rooster (酉年) Role: Main Dancer, Vocalist

As the oldest member, Yu carries the interesting burden of having the most developed Saju chart — more life experiences have shaped how his elemental energies express themselves. His double-earth configuration (Taurus + Rooster's earth affinity) makes him the most stable presence in the group, though this manifests primarily in his dancing rather than his personality.

Watch Yu perform sometime and notice how his movements feel rooted even during the most complex choreography. That's his Saju showing through his art. There's a reason he became the main dancer — his earth energy gives him an intuitive understanding of physical space that other elemental types often struggle to achieve.

Best Compatibility: Fellow earth signs (Taurus, Virgo, Capricorn) will feel immediately comfortable around Yu's energy. Those born in Ox or Snake years will find an almost instant understanding. If your chart shows Water elements, you might discover that Yu provides exactly the stability you've been looking for.

Compatibility Challenge: Strong Air sign placements (Gemini, Libra, Aquarius) might find Yu's methodical approach to life somewhat restrictive. The key is recognizing that his steadiness isn't rigidity — it's reliability.

Haru: The Aquarius Rooster Innovator

Birth Date: January 23, 2006 Western Zodiac: Aquarius Chinese Zodiac: Rooster (酉年) Role: Vocalist, Dancer

Here's where things get interesting from a Saju perspective. Haru's Aquarius energy creates tension with his Rooster birth year in a way that actually produces creative friction. Aquarius wants to break rules and innovate; the Rooster wants perfection within established systems. This internal push-and-pull often produces the most artistically interesting individuals.

In NEXZ, Haru is frequently the member who suggests unexpected approaches during creative sessions. His Saju chart shows strong "innovation gates" — points where his elemental energies allow for unconventional thinking that still produces practical results.

Best Compatibility: If you have strong Aquarius, Gemini, or Libra placements, Haru's energy will feel exhilarating. Those born in Dragon years (2000, 2012) often find a particular spark with Rooster individuals — there's a natural complementarity that shows up as creative collaboration.

Compatibility Challenge: More traditional earth sign configurations might find Haru's constant innovation exhausting. If your chart emphasizes stability and routine, you'll need to appreciate his creativity without expecting him to settle into predictable patterns.

So Geon: The Virgo Dog Perfectionist

Birth Date: September 13, 2006 Western Zodiac: Virgo Chinese Zodiac: Dog (戌年) Role: Vocalist

So Geon is the only Korean member in NEXZ, and his Saju chart reflects something quite different from his Japanese groupmates. His Virgo-Dog combination creates what practitioners call a "service-oriented heart" — an individual whose deepest fulfillment comes from contributing to others' wellbeing.

The Dog year adds a layer of protective loyalty that combines beautifully with Virgo's attention to detail. So Geon is likely the member who notices when something is slightly off with a groupmate and quietly addresses it without making a big deal. His earth-heavy chart also suggests he serves as an emotional anchor during stressful periods.

Best Compatibility: Those born in Tiger years (1998, 2010) or Horse years (2002, 2014) form the "loyalty triangle" with Dog individuals. If your chart shows strong earth or water elements, So Geon's caring nature will feel deeply nurturing rather than overwhelming.

Compatibility Challenge: Fire-dominant charts might perceive So Geon's attention to detail as nitpicking rather than caring. Understanding that his corrections come from a place of wanting everything to be the best it can be helps reframe this dynamic.

Seita: The Sagittarius Dog Adventurer

Birth Date: November 28, 2006 Western Zodiac: Sagittarius Chinese Zodiac: Dog (戌年) Role: Rapper, Vocalist

Seita's chart presents one of the more dynamic combinations in NEXZ. Sagittarius fire energy wants to explore, expand, and experience everything possible. The Dog year adds loyalty but also a protective wariness of strangers. This creates an individual who is incredibly adventurous with people he trusts while remaining cautious with new connections.

In terms of his rap style, this Saju configuration likely influences his wordplay — Sagittarius fire gives him the confidence to take linguistic risks, while Dog loyalty means his lyrics often center on themes of friendship and commitment.

Best Compatibility: If your chart shows Fire elements (Aries, Leo, Sagittarius placements), Seita's energy will feel immediately familiar. Those born in Tiger or Horse years often experience strong connections with Dog individuals, particularly when Fire signs are involved.

Compatibility Challenge: Strong Water placements might find Seita's directness uncomfortable. His Sagittarius honesty combined with Dog loyalty means he says exactly what he thinks to people he cares about — which isn't always what they want to hear.

Hyui: The Taurus Pig Creative

Birth Date: May 11, 2007 Western Zodiac: Taurus Chinese Zodiac: Pig (亥年) Role: Main Rapper, Vocalist, Dancer

The youngest Taurus in the group, Hyui's Pig year adds a creative dimension to his earth-heavy chart that manifests most clearly in his rap style. The Pig is associated with the Water element in Chinese astrology, which softens Taurus's sometimes rigid earth energy and allows for more emotional expression.

This Water-Earth combination often produces individuals with excellent artistic instincts and the discipline to develop those instincts into genuine skills. Hyui's position as main rapper suggests his chart's creative potential found the right outlet through lyrical expression.

Best Compatibility: Rabbit year (1999, 2011) and Goat year (2003, 2015) individuals form the "creativity triangle" with Pig individuals. If your chart shows Water elements or Cancer/Scorpio/Pisces placements, Hyui's emotional depth will resonate strongly.

Compatibility Challenge: Highly analytical charts (strong Virgo or Capricorn influence) might find Hyui's creative approach frustrating. He likely makes decisions based on feeling rather than pure logic, which can create friction with more systematic thinkers.

Yuki: The Virgo Pig Maknae

Birth Date: September 20, 2007 Western Zodiac: Virgo Chinese Zodiac: Pig (亥年) Role: Vocalist, Dancer, Maknae

As the youngest member, Yuki's Saju chart is still developing in terms of how his elemental energies express themselves through life experience. However, his Virgo-Pig combination already shows a interesting blend of analytical thinking and creative intuition that will likely become more pronounced as he matures.

The Virgo earth element combined with the Pig's Water association creates someone who can both dream big and execute the practical steps necessary to achieve those dreams. For the maknae of a competitive idol group, this is exactly the configuration you'd want.

Best Compatibility: Similar to Hyui, Rabbit and Goat year individuals will find natural harmony with Yuki's Pig energy. Cancer, Scorpio, and Pisces placements will appreciate his emotional intelligence, while fellow Virgos will understand his attention to detail.

Compatibility Challenge: Strong Fire placements might find Yuki's Virgo caution slowing down their natural enthusiasm. The key is recognizing that his careful approach comes from a desire to do things right, not a lack of passion.

Finding Your NEXZ Soulmate

Understanding these Saju configurations is just the beginning. True compatibility depends on your complete birth chart — your year, month, day, and ideally your birth hour all contribute to your elemental composition.

What I find most beautiful about Saju compatibility is that it doesn't judge — it simply reveals. Maybe your cosmic match isn't your bias, and that's perfectly okay. Sometimes understanding why you're drawn to certain energies helps you appreciate all the members in new ways.

NEXZ is still early in their journey, but their Saju compositions suggest a group with the elemental balance necessary for longevity in the industry. The combination of Rooster precision, Dog loyalty, and Pig creativity creates something that feels both fresh and stable — exactly what JYP was likely hoping to achieve with their Japan-based venture.
