Japanese-Built J-Tower 3: Phnom Penh’s Next Iconic Vertical Landmark

Written By chheng leang

Phnom Penh’s skyline is entering a new era. As Cambodia continues its long-term urban transformation, a new landmark is rising in the heart of the capital—J-Tower 3, a 320-meter, 77-storey luxury residential tower designed to redefine vertical living in Cambodia.

Developed by Tanichu Assetment Co., Ltd., a Japanese-backed developer with a proven track record in Phnom Penh, J-Tower 3 is positioned not just as the tallest building in Cambodia, but as a statement of where the city is heading.

A New Benchmark for Phnom Penh’s Skyline

At 320 meters, J-Tower 3 will stand as:

  • Cambodia’s tallest building

  • A capital-city landmark in South BKK1, Tonle Bassac

  • Among the Top 10 tallest buildings in Southeast Asia (2023, architecturally topped-out comparison)

Beyond height, the project represents confidence—confidence in Phnom Penh’s future as a regional capital city and in long-term urban living.

Project Overview at a Glance

  • Project: J-Tower 3 Condominium

  • Developer: Tanichu Assetment Co., Ltd. (Japan-affiliated)

  • Location: South BKK1, Tonle Bassac, Chamkar Mon

  • Total Floors: 77

  • Height: 320 meters

  • Total Units: 360 units (all 3-bedroom layouts)

  • Net Unit Sizes:

  • Ceiling Height: 3.0 – 4.5 meters

  • Ownership: Strata Title

  • Foundation Depth: 80 meters

  • Target Completion: Q4 2028

This is a low-density high-rise by design—quality over quantity, with generous unit sizes rarely seen in modern Phnom Penh developments.

Designed for “7-Star Hotel” Living

J-Tower 3 adopts a hospitality-driven concept, integrating wellness, leisure, and social spaces across multiple vertical zones.

Signature Facilities Include:

77th Floor

  • Sky Bar (resident-only)

  • Infinity Pool — the highest in Phnom Penh

50th Floor

  • Grand Main Lobby

  • Private Luxury Lounge

  • Café & Mini-Shop

49th Floor

  • Indoor Pool & Kids Pool

  • Sauna, Spa & Wellness Facilities

11th Floor

  • Playground

  • Bowling Lane

  • Karaoke Room

  • Billiard Room

  • Nurse Station

24/7 Security & On-site Health Support

  • Nurse station and AED systems

This vertical zoning mirrors high-end hotel planning—public, semi-private, and private spaces are clearly separated.

Spacious Residences with Practical Luxury

Unlike many compact condominiums in Phnom Penh, J-Tower 3 offers only 3-bedroom residences:

Unit Types

Type A

  • 166 sq.m (Net)

  • NE / SE / NW / SW orientations

  • Units: 01, 03, 05, 07

Type B

  • 178 sq.m (Net)

  • East / West orientations

  • Units: 02, 06

Large living areas, proper kitchens, and elevated ceiling heights position these homes for end-users, families, and long-term residents, rather than short-term speculation.

Strategic Location: South BKK1, Tonle Bassac

J-Tower 3 sits in one of Phnom Penh’s most established diplomatic and lifestyle districts:

5–10 minutes to:

  • Independence Monument

  • Royal Palace

  • AEON Mall

  • Koh Pich (Diamond Island)

  • Embassies & key institutions

Excellent access via:

  • Norodom Blvd

  • Monivong Blvd

  • Mao Tse Toung Blvd

Close proximity to the Mekong & Tonle Sap rivers

This location balances prestige, convenience, and long-term land value.

The Developer Track Record Matters

Tanichu is not new to Phnom Penh:

  • J-Tower 1 – Completed

  • J-Tower 2 – 43 floors, sold out in just 5 weeks

  • J-City Condominium – First Japanese-owned condo in Cambodia

  • J-Village BKK1 – Boutique residential project

This history gives J-Tower 3 credibility in execution, delivery, and post-completion management.

Final Thoughts: Who Is J-Tower 3 For?

J-Tower 3 is not for everyone—and that is precisely its strength.

It is best suited for:

  • Buyers seeking iconic, long-term assets

  • End-users wanting space, privacy, and prestige

  • Investors focused on capital preservation in prime CBD land

  • Buyers who value Japanese-influenced planning discipline

As Phnom Penh evolves, true landmarks will be limited. J-Tower 3 positions itself as one of those rare vertical assets that defines an era.
