About Us
Founded in June 2025 in Chuo-ku, Osaka, Towa Construction Co., Ltd. provides high-quality design and supervision services led by Japan's first-class licensed architects.
Guided by our principles of "sincerity" and "devotion", we partner closely with each client to translate their intentions into built form. Our practice spans Japan luxury house construction, hotel construction, office building construction, residential renovation, and clinic / retail design across Osaka and the wider Kansai region.
A first-class architect and a first-class construction manager work together to deliver a single, accountable line from planning to handover.

Services
Whether you are commissioning a Japan luxury home, a boutique hotel, or an office building, we begin with rigorous site analysis and a programme that balances function with poetry. We work across residential, commercial, medical, and retail typologies.
From detailed drawings to on-site supervision, a first-class licensed architect remains accountable throughout. We protect quality, budget, and timeline so the building you imagined is the building you receive.
We preserve the value embedded in existing buildings while transforming them for contemporary life — including seismic reinforcement and energy-efficiency upgrades required under current Japanese code.
