Daikazoku-no-Yu in Okayama: Pool and Onsen Prices, Rules and Access
Daikazoku-no-Yu’s pool ticket includes bath entry; bring a swimsuit, and check which of its 27 baths are natural springs before choosing.
Checked: September 28, 2026
Daikazoku-no-Yu works best for a family outing where the children want a pool and adults also want a proper bath. Its four pool areas include a 20-metre lap pool, a shallow children’s pool, a lazy river with a slide and a jacuzzi. After swimming, the same ticket lets you use the bathing area. If you only want a soak, buy the lower-priced bath-only ticket.

The Okayama tourism association currently lists these pool-bundle prices. The facility’s own price page and LINE listing show lower figures, so there is a live discrepancy between official listings. Treat the higher tourism-association price as a planning estimate and confirm the day’s ticket price with the facility before travelling.
Which pool suits your child?
The 20-metre pool is about one metre deep. It is useful for swimming lengths or walking in the water, but it is not a toddler pool. The small “Momoiruka” pool is 35 cm deep. A separate lazy river has a slide, and the jacuzzi gives adults and children another place to warm up between swims.
Swimwear is required throughout the pool zone, and the facility does not rent it. Children who are not toilet-trained must wear a swim diaper under their swimsuit. An adult accompanying a child into the pool also pays the pool-bundle price, even if that adult does not swim. Children may not use the pool without a parent or guardian.
The operator’s posted mixed-bathing rule for children is limited to pupils through first grade who are also 120 cm tall or shorter. Both conditions matter. For a child near either cutoff, ask staff before relying on cross-gender bathing arrangements.
The bath area has more than one kind of water
The bath floor plan labels a source-water bath, but the facility does not identify all 27 pools as natural onsen. The children’s “Momokujira” bath is specifically described as soft water. It is more accurate to say the complex has a natural-spring bathing area than to describe every tub as spring water.
The operator does not publish a current source-water temperature, flow rate or complete analysis for the Daikazoku spring. Avoid borrowing values from Momotaro Onsen or another Okayama bath just to fill that gap. Pool water and bath water are also separate products: a pool ticket grants entry to both zones, but it does not make the swimsuit area a natural hot spring.
Hours are 7 a.m.–11 p.m., with admission ending at 10 p.m.; bathing and pool use finish by 10:45 p.m. The facility says it is open year-round, with possible maintenance closures. Children under 12 must be accompanied, and the bathing area does not allow tattoos or tattoo-style stickers. The rules also restrict assisted bathing: a same-gender caregiver must accompany anyone who needs bathing assistance, and wheelchairs cannot be used inside the bathing area. Contact the facility if those conditions affect your visit.
Getting there from Okayama
From Okayama Station’s east exit, take the bus from platform 5 towards Kurashiki or Nakasho and get off at Tekko Center-mae; the ride is about 30 minutes, followed by a five-minute walk. JR Kita-Nagase Station is about a 20-minute walk away. Drivers have access to a large free parking lot. Check the bus operator’s current timetable before setting out, especially if you are planning an evening visit.
For a bath-only visit elsewhere in the prefecture, compare the Yubara Onsen day-trip guide or Sagi-no-Yu at Yunogo Onsen; those are onsen-area alternatives, not pool complexes.
