Yamanami no Yu: Is the Two-Hour Ticket Enough?
At Yamanami no Yu, ¥600 covers two hours in the bath and pool; the ¥900 day ticket suits a swim, a longer rest or a family visit.
Checked: September 27, 2026
Yamanami no Yu is a large day-use complex beside Kosei Fureai Park, with an onsen, indoor pool, rest spaces and saunas. Its ticket includes the bath and pool together, even if you only plan to soak. That makes the choice simple: pay ¥600 for two hours if you are there for a bath and one sauna cycle; spend ¥900 for the day if swimming or a longer family stop is part of the plan.
What changes between the tickets
| Ticket | Adult | Best fit |
|---|---|---|
| Two hours | ¥600 | Bath, cold/source pools and sauna without a long break |
| Day use | ¥900 | Pool time, a longer lounge break or an unrushed family visit |
The facility’s current page says both bathing and pool admission are included. Children under three enter free; for older children, confirm the current ticket price with the venue before you go. A separate nighttime rate also appears on the operator’s price page, but the eligible hours are not clear in the published text.
The 15-by-8-metre leisure pool has a one-metre depth, with a shallow toddler pool, an aqua pool and a jacuzzi nearby. Bring a swimsuit and swim cap. The bath side lists eleven pools, including an outdoor bath, a source-water pool, a cooler pool and electric, bubble and reclining baths. Three sauna types are listed: high-temperature, steam and mist.
Families need to know the diaper rule
People who cannot control excretion and routinely wear diapers may not use the shared baths or pool. The rule also covers temporary use and swim diapers. For young children still in diapers, the venue provides a dedicated baby bath. That is a meaningful option for a parent who wants to bathe, but it does not make the pool or shared pools available to the child.
The day ticket becomes easier to justify when the group can split up: one adult can swim with an older child while another uses the baths or the 90-mat lounge. The two reservable Japanese rooms—10 and 15 mats—cost extra and need to be arranged at reception; they are not included with the day ticket.
Getting there and checking the sauna
The venue is about 40 minutes by bus from Kofu Station on the Kaji-kawa-bound route, followed by a walk of around five minutes from the Yamanami no Yu stop. Service is much less frequent than a city bus, and the operator’s published timetable marks some trips as not running on weekends or holidays. Check the day’s return bus before you settle in. By car, the facility sits within the park complex and is easier to pair with other stops in the southern Kofu Basin.
Yamanami is closed Wednesdays, moving the closure to Thursday when Wednesday is a public holiday; the facility lists exceptions during Golden Week, Obon and the New Year period. Its high-temperature sauna underwent city-listed repair work in 2026, but one-off maintenance can still affect an individual room, so check current notices if sauna access is the main reason for going. The Kofu sento guide is a better match for a short, bath-only visit in town.
