Overview
Montevan Resort Villa gives you a private onsen resort villa stay in Tateyama, Chiba, near the southern edge of the Bōsō Peninsula. You stay in a full private rental, limited to only three villas per day, with your own garden pool, natural hot spring open-air jacuzzi bath, and private sauna. The property opened in 2023 and focuses on freedom, privacy, and the feeling of having your own countryside retreat by the coast.
This is a good choice when you want more than a standard hotel room. You can swim, cook, grill outside, soak in natural hot spring water, use the sauna, and spend long hours with people important to you without moving around shared spaces. The villa style also suits longer stays, since you have a living room, dining kitchen, bedrooms, laundry area, baths, and outdoor space all to yourself.
Accommodation
You stay in a maisonette-style private villa set on about 270 square meters of space. Each villa includes two bedrooms, a spacious living room, a dining kitchen, a laundry area, an indoor natural hot spring bath, an outdoor natural hot spring jacuzzi bath, a private sauna, and a garden pool. The pool measures 6 meters by 3 meters and has a depth of 1.1 meters, so you can move easily between the living area, poolside, bath, and sauna throughout the day.
The sleeping space includes three Simmons double beds, with futons prepared when your stay requires extra bedding. This gives you a flexible setup for family time, group trips, or a longer coastal holiday. The villa keeps the layout simple and open, so you can gather in the living room, cook in the kitchen, relax outside, and return to the bedrooms when you want quiet rest.
You also have Wi-Fi, TV, refrigerator, microwave, IH cooktop, coffee maker, kettle, rice cooker, hair dryer, slippers, bathrobes, shampoo, conditioner, toothbrushes, hairbrushes, razors, cotton, cotton swabs, body towels, bath towels, face towels, hair iron, mineral water, and ice prepared in the villa. The room feels practical as well as comfortable, especially if you want to stay in and enjoy the property rather than go out for every meal.
Dining
Montevan does not center your stay around a fixed ryokan dinner. Instead, you shape your own dining experience in the villa. You can cook in the dining kitchen, bring fresh ingredients from Tateyama, or spend the evening grilling outside. The kitchen setup includes IH cooking equipment, refrigerator, microwave, rice cooker, kettle, coffee maker, and tableware, so you have what you need for relaxed self-catering.
For a more memorable dinner, you can request the gas BBQ grill for an additional fee before your stay. Basic BBQ equipment such as tongs, grill net, and chopsticks can be prepared with the rental, while you bring your own favorite ingredients. This makes dinner feel casual and personal, especially when you want to eat poolside instead of sitting in a restaurant.
You can also order optional food sets by phone in advance. The official option menu includes Bōsō seafood BBQ sets, a premium seafood BBQ set with items such as spiny lobster, clams, prawns, and abalone, a meat BBQ set, wagyu kalbi, local sashimi selected according to the day’s catch, and local fish sushi. Availability can change with weather and sourcing, so you should reserve food options early and confirm details directly before your stay.
Each villa also has a KIRIN TAPPY server. You can request draft beer, highball, or sour options for an added charge by contacting the service desk during business hours. This works well when you want the feel of a private resort evening without leaving your villa.
Onsen and Wellness
Montevan now draws natural hot spring water into each villa’s baths. The spring is named Kaori no Yu and completed its hot spring registration in 2025. The source is a sodium-chloride spring, classified as a low-tonicity, weakly alkaline cold natural hot spring. The source temperature is 18.8°C, and the water is heated to a bathing temperature, with added water, and is not for drinking.
You can enjoy the hot spring in two private ways: an indoor natural hot spring bath and an outdoor natural hot spring jacuzzi bath. The outdoor bath lets you soak in the open air after swimming or sauna time, while the indoor bath gives you a quieter bathing option at any hour. Traditional listed bathing benefits include relief for muscle pain, joint pain, neuralgia, frozen shoulder, chronic-stage bruises and sprains, chronic digestive issues, hemorrhoids, sensitivity to cold, fatigue recovery, and general health support.
A private sauna adds another layer to the stay. The official news notes that barrel saunas were added to all three villas in summer 2025, so you can move between sauna, pool, and hot spring bath within your own space. You do not need to book a bathing slot or share a wellness area with anyone outside your villa.
Guests with tattoos
You never need to worry about tattoos at Montevan. All bathing facilities remain completely private and reserved for your villa only. You use the indoor mineral bath and outdoor jacuzzi freely, without restrictions or concerns.
Facilities
Each villa includes everything needed for short or extended stays. You have a laundry area, allowing you to wash clothes during longer visits or after beach outings. Wi-Fi covers the entire villa, making it easy to work remotely or stream entertainment.
Parking space accommodates two vehicles directly at the villa. If your group arrives with more cars, a second parking area remains available nearby. Safety equipment, including smoke detectors, fire extinguishers, and evacuation ropes, is installed throughout the property.
Check-in runs from 15:00 to 20:00, with check-out at 10:00. You can request late check-out for an additional fee. Stays of up to 28 nights are possible, making Montevan suitable for extended holidays or workations.
The villa maintains clear house rules to protect comfort and condition. You cannot bring pets, smoke inside or outside, or hold parties or events. These rules help preserve the calm atmosphere and quality of the space.
Activities
Your stay at Montevan encourages a slow, flexible rhythm. You swim in the garden pool during the day, relax indoors during the afternoon, and soak in mineral baths at night. You plan your schedule without external pressure.
The Tateyama area offers beaches, coastal drives, and scenic viewpoints, all within easy reach by car. You can explore local seafood restaurants, roadside markets, and quiet fishing towns nearby. After a day out, you return to a private space that feels removed from crowds and noise.
The villa also works well for days spent entirely on-site. You read, cook, talk, swim, and rest without leaving the property. Many visitors choose to spend most of their stay within the villa itself.
Additional features
Montevan Resort Villa focuses on giving you a place that feels personal rather than commercial. You stay in a full private home, enjoy your own pool and mineral baths, and live at your own pace from arrival to departure.
Amenities include bathrobes, towels, toiletries, hair dryers, hair irons, slippers, mineral water, ice, and barbecue equipment. Everything remains prepared so you can focus on enjoying your time instead of managing details.
Montevan suits travelers seeking space, privacy, and freedom. You arrive with people important to you, settle in, and experience Tateyama as if it were your own countryside retreat.
