スーパー銭湯 青の洞窟

千葉ニュータウン中央駅からレンタサイクルで15分。 フィットネスクラブ付属の温浴施設。 １階が浴室となっており、様々な熱湯、オートロウリュのサ室、水風呂チラーでキンキン、ととのい椅子ありと一通り揃っています。 ただオートロウリュはちょっと熱くなるくらいでサウナーには不完全燃焼。 2階にはくつろぎ空間に何故かテントが設置されています。 飲食できるスペースもあり（販売は自販機のみ）、コワーキングスペースあり、クレーンゲームありと充実。 一通り揃っているのですがどれもも中途半端な感じ。 長時間滞在する感じではありません。 平日750円、休日850円とお値段的にはリーズナブルなのでサクッとお風呂はいるのに向いています。

Very relaxing onsen. The shower heads have all been replaced recently, so they deliver a stronger stream than previously. The second floor’s rest areas are comfortable, although the tents are very popular so you’re unlikely to find an open one.

Decent public bath with gym, and friendly staff, many users are local factory workers who come in covered in grime and often skip showering before entering the bath. I raised this with management, but they admitted they couldn’t do much. I even developed foot fungus while using the facility, which led me to cancel my membership. If hygiene rules were respected, it could be a great place but as it stands, you might feel like you need another bath afterward.

It's hard to find the entrance. Other than that, bath temperature was moderate, and interiors are like a glamping. Wifi is strong, so I may come here again.

At least it's clean, but the water is plain and not natural. Baking soda water.
