The meals were delicious, and the Room was clean.
The staff's service was excellent. The female doorman at the entrance provided great assistance. The meals were delicious, the Room was clean, and the bath was amazing. I will definitely stay here again.

Is it a lapse in memory or the passage of time?
This was our third stay, following visits in 2019 (with a 7-month-old) and 2021 (with a 2.5-year-old), all in the Welcome Baby Room. However, our rating has dropped due to the following three points: 1. Passive Smoking While I had previously noticed that this facility seemed "smoker-friendly" (e.g., allowing IQOS smoking in the café area), I was very uncomfortable seeing people smoking near an ashtray placed right by the entrance. In this day and age, having an ashtray at the entrance feels outdated and inappropriate for a Welcome Baby Accommodation. 2. Room Odor I don't recall noticing it during previous stays, but upon entering the room this time, there was an unpleasant smell resembling urine. While my nose eventually adjusted to it, it did detract from our enjoyment by about 10%. It wasn’t just musty or dusty like older Ryokan might have—it specifically smelled like urine. 3. Buffet Dinner times were assigned on a first-come-first-served basis at check-in, meaning late check-ins could result in dinner being as late as around 8 PM—a challenge for families with young children who usually eat at 6 PM like ours. Additionally, while buffet-style dining may often be hit-or-miss, we found some dishes disappointing; for example, Wakayama ramen tasted overly diluted—more like water than proper broth or seasoning—and desserts were quite limited in variety. Not necessarily a negative point but worth noting: The pool is fairly deep at about 120 cm; small children who cannot swim with their faces underwater will need floaties and goggles. On the plus side, changing areas are shared with the bathhouse facilities and towels are conveniently provided. While its proximity to Adventure World is great, we likely won’t choose this accommodation again next time.
