About Natural Hot Spring Heiwajima Tokyo Ticket

Natural Hot Spring Heiwajima is one of the most well-rounded and accessible onsen facilities available in central Tokyo — a 24-hour spa complex inside the BigFun Heiwajima shopping complex in Ota City, just 15 minutes by shuttle bus from Haneda Airport and easily reached from central Tokyo by a short trip on the Keikyu Line. The natural spring source was discovered in 1986 at a depth of 2,000 metres, and the high-quality sodium-chloride spring has been drawing visitors ever since for its distinctive therapeutic and beauty properties.

The bathing area is divided into separate male and female sections and features an impressive range of hot spring experiences. The main large bath and open-air pools are the heart of the facility — soaking in the sodium-chloride spring water prevents sweat evaporation from the skin, creating a natural moisturising and warming effect that is particularly effective in cooler weather. The high-concentration nano-carbonated spring is one of the standout baths — extremely rich in carbon dioxide, the water creates a dramatic fizzing sensation on the skin and is highly praised for improving blood flow and skin softness. The Togol bath provides targeted hydro-massage relief for lower back pain, stiff shoulders, and joint aches, while the lying bath and jet bubble bath add further variety to a comprehensive bathing circuit. The Löyly sauna — a Finnish-inspired aromatic steam sauna — rounds out the bathing experience with deeply penetrating heat and negative-ion steam.

Beyond the baths, Heiwajima's relaxation facilities are outstanding — sofa TV lounges, reclining chairs, a free book lounge with 10,000 comics and magazines, gender-segregated quiet rest rooms, a dining area, and a full range of massage and beauty treatments. Large suitcase lockers are available, and the free shuttle bus service to Haneda Airport (running in the early morning and at midnight) makes Heiwajima the perfect pre-flight or post-flight retreat for international travellers.

The nano-carbonated spring is not to be missed — the fizzing sensation on the skin is extraordinary and the skin-softening effect is immediately noticeable after even a short soak.
