Hi everyone, I’m Suke-san! I’m an ordinary Japanese office worker, but I had the amazing opportunity to study abroad in Boston, Massachusetts for a year.

I’m turning 30 this year, and with my income finally stabilizing, I’ve been able to travel around Japan a lot more lately (laughs). My experience living in the US gave me a strong desire to use my English to help international visitors have an even better time while exploring Japan.

That’s exactly why I’ve decided to share my personal recommendations for domestic travel spots and the best ways to enjoy them. I really hope my local insights can help you plan the perfect trip!

For this adventure, I visited the spectacular Hoshinoya Karuizawa—a renowned resort that holds a very special place in the hearts of those in the know. I’m excited to share my honest, realistic review of this stay from a true Japanese local’s perspective!

Overall Review of Hoshinoya Karuizawa

If you are looking to experience the heart of traditional Japanese hospitality (Omotenashi) and are craving a true luxury getaway, I cannot recommend this hotel enough.

At around ¥100,000 (roughly $700 USD) per night, Hoshinoya Karuizawa sits firmly in the ultra-premium category of Japanese accommodations. But to fully understand the price, you first have to understand the location.

The “Karuizawa” Status

In Japan, Karuizawa is famous as an exclusive mountain retreat. Here’s a local pro-tip: if a Japanese person casually mentions they have a vacation home in Karuizawa, they are essentially saying, “I am very wealthy.” The standard response is to act highly impressed (laughs)!

To give you an idea of the area’s premium pricing, let’s look at APA Hotel. APA is a ubiquitous budget chain in Japan known for being cheap, spotless, and almost entirely automated (meaning very little human interaction). Normally, a great room at an APA hotel costs around ¥7,000 ($50 USD) a night. In Karuizawa? That exact same APA Hotel jumps to about ¥30,000 ($200 USD)—four times the usual price!

Is $700 a Night Worth It?

Personally, I think it is absolutely worth it. If you spend $700 a night in a major US city, you’ll likely get a beautiful downtown room and above-average service. But at Hoshinoya Karuizawa, that same price unlocks the absolute pinnacle of Japanese quality and care.

Here is what that level of meticulous service actually looks like:

• Seamless Transit: Your luxury experience starts immediately with a dedicated shuttle bus from the nearest station.
• The Warmest Welcome: You are greeted by staff with deep, respectful bows the moment you arrive.
• Immersive Check-in: While waiting at reception, you are treated to live, traditional Japanese music that instantly sets a tranquil, “Wa” (Japanese harmony) atmosphere.
• Personal Escort: A staff member personally guides you and your party to your room.
• Garden Welcome Ceremony: After settling in, you are invited to the garden for a complimentary welcome ceremony featuring traditional Japanese tea and dango (sweet rice dumplings).
• Ultimate Freedom: From there, the time is yours to soak in the hot springs (onsen) or simply relax at your own pace.

To be completely honest, a carefully crafted experience like this is exceptionally rare, even here in Japan. If you want to be treated to the absolute highest echelon of Japanese hospitality, Hoshinoya Karuizawa is the place to be.

The Charm of Hoshinoya: A Japanese Guest’s Perspective

I know I got a little carried away in the last section talking about how luxurious Hoshinoya is (laughs)!

But to truly understand the charm and prestige of this specific hotel, you need to understand where it fits within the famous “Hoshino Resorts” family.

Hoshino Resorts is a highly respected Japanese hotel management company that operates several different brands across the country. Here is a local secret: the specific brand you choose to stay at says a lot about you in Japan!

• “I stayed at Hoshinoya.” If a Japanese person says this, the unspoken translation is: “I earn a pretty good living.” Hoshinoya is the absolute top-tier, flagship brand of the entire group. It is the ultimate bucket-list destination that almost everyone in Japan dreams of experiencing at least once.
• “I stayed at a Hoshino Resort.” If someone mentions staying at one of their other brands, the translation is: “I am a smart traveler who knows how to perfectly balance cost with high-quality experiences.” So, what are these other brands? To give you the full picture, here is a quick breakdown of the Hoshino Group’s hierarchy:
• HOSHINOYA (星のや): The absolute pinnacle of luxury, offering overwhelming, extraordinary experiences (This is where I stayed in Karuizawa!).
• KAI (界): Premium, traditional hot spring inns (ryokan) that focus heavily on local Japanese culture and regional craftsmanship.
• RISONARE (リゾナーレ): High-quality, western-style resort hotels designed for families and active travelers looking for nature and adventure.
• OMO (おも): Stylish, casual, and affordable city-center hotels designed to help you explore urban neighborhoods like a local.
• BEB (ベブ): Super laid-back, budget-friendly hotels aimed at younger travelers who just want a cool place to hang out with friends.

As you can see, the Hoshino group has something great for everyone. But when you book a room at Hoshinoya, you aren’t just booking a nice place to sleep—you are reserving the absolute peak of Japanese hospitality and luxury.

The History of Hoshino Resorts

Now that you know how prestigious the brand is, you might be wondering: how did it all start? Well, the entire Hoshino Resorts luxury empire actually began right here in Karuizawa over a century ago!

Back in 1914, the founder, Kuniji Hoshino, opened a single traditional hot spring inn called Hoshino Onsen Ryokan. At the time, Karuizawa was just beginning to gain traction as a popular summer retreat. But this ryokan wasn’t just a place to sleep and bathe—it quickly became a vibrant cultural hub.

During the 1920s (the Taisho era in Japan), some of the country’s most famous authors, poets, and intellectuals would gather at Hoshino Onsen Ryokan. They even held summer seminars where they would soak in the hot springs and passionately debate art, literature, and liberal education. Imagine the energy of having all those brilliant minds hanging out in one secluded mountain inn!

Another beautiful part of their history is their deep respect for nature. The second-generation owner, Yoshimasa Hoshino, was a huge birdwatching enthusiast. He partnered with wildlife experts to protect the local environment, which eventually led to the creation of the Karuizawa National Wild Bird Sanctuary right next door. That philosophy of “coexisting with nature” is still a massive part of the resort’s identity today.

Fast forward to the 1990s, the fourth-generation heir and current CEO, Yoshiharu Hoshino, took the helm. He rebranded the company into “Hoshino Resorts” and masterfully blended traditional Japanese ryokan culture with modern international luxury. In 2005, right on the exact same grounds where the original 1914 inn stood, he opened the breathtaking Hoshinoya Karuizawa.

So, when you stay here, you aren’t just checking into a fancy hotel—you are stepping into a living piece of Japanese literary and cultural history!

The History of Karuizawa as a Mountain Resort

Before we dive into the stunning scenery of the hotel, I have to quickly mention why Karuizawa feels so uniquely different from other Japanese towns.

While I mentioned earlier that it’s an exclusive vacation spot for the wealthy, it actually owes its entire resort status to a Canadian missionary named Alexander Croft Shaw. Back in 1885, he visited Karuizawa and felt the cool, crisp mountain air reminded him of his home. He built the very first summer villa here, and soon after, other Western expatriates and Japanese elites followed his lead.

Because of these foreign roots, Karuizawa has a fascinating East-meets-West vibe. As you walk around town, you’ll find historic wooden churches, authentic European-style bakeries, and Western architecture nestled right next to traditional Japanese hot springs. It’s a beautifully blended culture that feels incredibly welcoming to international visitors!

Alright, enough history lessons—let’s finally talk about what it actually looks and feels like inside Hoshinoya Karuizawa!

Scenery and Interior Design of Hoshinoya Karuizawa

The concept of Hoshinoya Karuizawa’s design is “Valley Village.” The guest rooms are scattered around a beautiful central river, designed to make you feel like you are living in a secluded, peaceful Japanese village rather than a standard hotel building.

To give you the most realistic idea of what to expect, I took plenty of photos of my actual room. I want to show you everything from the traditional Japanese entranceway to the stunning wooden bath.

Let’s take a virtual room tour, step by step!

Other Amenities & Room Wear (その他備品)

If you’re moving around inside the hotel, you should definitely wear the samue (traditional Japanese work clothing). It might feel a little embarrassing to wear it while moving around, but it’s a great way to immerse yourself in the world of Hoshinoya, so I recommend it.

How to Make the Most of Your Stay at Hoshinoya Karuizawa

One of my absolute biggest tips for staying here is to actively participate in the complimentary guest activities! Hoshinoya offers several amazing free tours and workshops, and joining them is the best way to fully immerse yourself in the resort’s calming atmosphere.

Here are three highly recommended experiences that you definitely shouldn’t miss during your stay:

Exclusive Early Morning Bird Watching (6:00 AM)

This guided tour starts at 6:00 AM, which is admittedly quite early! In fact, because of the early wake-up call, when my wife and I joined, we were the only participants (laughs). But getting out of bed was entirely worth it. We got to explore the very same tranquil ponds and deep forests that the historical presidents of Hoshino Resorts used to walk through. Having that pristine, natural environment completely to ourselves to watch the wild birds was an unforgettable, luxurious experience.

Traditional “Washi” Postcard Making (9:00 AM – 3:00 PM)

This is an incredibly easy and flexible activity that you can drop into anytime between 9:00 AM and 3:00 PM. The concept is beautifully simple: you use colorful Washi (traditional Japanese paper), a blank postcard, and some glue to decorate your own design. Even though it’s simple, your unique personality really shines through in how you arrange the paper! It’s very fun, and the best part is that you get to take it home as a personalized, one-of-a-kind souvenir to remember your time in Karuizawa.

Refreshing Morning Stretch (8:00 AM)

If the 6:00 AM bird watching is a bit too early for your vacation schedule, I highly recommend the 8:00 AM Morning Stretch! Guests gather together to take deep, mindful breaths and gently stretch their bodies. Traveling can sometimes throw off your physical rhythm, so this is a fantastic way to reset and condition your body. It is highly recommended because it gives you the perfect opportunity to feel the crisp, incredibly clear morning air that is so unique to Japan’s mountainous regions.

Hoshinoya Karuizawa FAQ

I have put together some of the most frequently asked questions about staying here!

Please take a look at the points below to help plan your trip.

How Do Japanese Locals View Hoshinoya Karuizawa?

To Japanese people, it is the ultimate luxury accommodation that perfectly blends good old-fashioned Japanese traditions with the latest modern comforts and stylish design. The price range is certainly not cheap, but if you are looking for a truly special and authentic experience, it is highly recommended!

When is the Best Time to Visit?

Karuizawa is famous as a summer retreat, so the peak season naturally falls during the summer (June to September). However, because there are so many tourists during this time, I actually recommend visiting during the off-season. I visited in March, which is still winter here. The clear night sky was a breathtaking view that you simply cannot see in Tokyo, and with fewer people around, the atmosphere was incredibly relaxing.

How Many International Guests Are There?

When I visited, it actually felt like I passed by more international tourists than Japanese guests! I would estimate that about 60% of the guests were from overseas. However, the staff are all Japanese, so you can still fully immerse yourself in the authentic Japanese atmosphere and hospitality.

Is the Accommodation Cost Worth It?

If you are willing to pay a premium for a relaxing time immersed in Japanese tradition, then yes, it is absolutely worth it! If you book more than three months in advance, there is an early-bird discount, making it a bit more affordable.

To give you an idea of the total cost, here is what we spent for a 3-day, 2-night trip for two people:

• Accommodation (2 nights): About 170,000 yen
• Meals (for two people over 3 days): About 50,000 yen
• Transportation (round trip from our home for two): About 30,000 yen
• Total: Approximately 250,000 yen

Do You Need a Rental Car to Get Around?

Not at all! There is a train that goes directly to Naka-Karuizawa, the nearest station to the hotel. If you book in advance, Hoshinoya provides a free shuttle bus from Naka-Karuizawa station.

Even if you don’t book the shuttle, there are plenty of taxis waiting at the station. It only costs about 1,000 yen one-way to get to the hotel.

On our way home, we took a taxi from the hotel to Karuizawa Station (which is a different station where the Shinkansen bullet train stops), and it cost about 3,000 yen one-way. There are no rip-off taxis in Japan, so you can use them with complete peace of mind!

What Are the Best Nearby Attractions?

Right near the hotel, you will find Sonmin-Shokudo (a great casual restaurant), Tombo-no-yu (a spacious hot spring facility), and Harunire Terrace (a beautiful wooden shopping and dining area). The best part? If you are staying at Hoshinoya Karuizawa, you can ride the free shuttle bus to all of these spots!

By combining these nearby attractions with the free activities inside the hotel, you can create the perfect itinerary. Here is exactly how we spent our 3 days, which worked out perfectly:

Day 1: Arrival and Relaxation

• 15:00 – Checked in and attended the welcome ceremony (enjoyed dango sweets and tea for about an hour).
• 16:00 – Soaked in the hot springs.
• 17:00 – Had a relaxing room service dinner (Requires advance reservation, about 10,000 yen per person).
• 22:00 – Took another bath in our private room tub.
• 23:00 – Went to sleep.

Day 2: Activities and Exploring

• 6:00 – Joined the early morning Bird Watching tour.
• 7:00 – Tour finished.
• 8:00 – Participated in the refreshing Morning Stretch.
• 9:00 – Ate breakfast in our room (Requires advance reservation, about 10,000 yen per person).

• 11:00 – Returned to the room and relaxed.
• 12:00 – Took the shuttle to Sonmin-Shokudo for lunch.
• 13:30 – Back to the room.
• 14:00 – Joined the free Washi postcard-making experience (no reservation needed).
• 15:00 – Back to the room briefly, then headed to Harunire Terrace to look at souvenir shops until 17:00.
• 18:00 – Had dinner at a restaurant in Harunire Terrace, bought some food for tomorrow’s breakfast, and returned to the room by 20:00.
• 20:00 – One last trip to the hot springs, returning to the room at 21:00.
• 21:00 – Relaxed, planned the next day, and went to bed at 23:00.

Day 3: Final Shopping and Departure

• 8:00 – Woke up and ate the breakfast we bought the night before.
• 9:00 – Morning soak in the hot springs.
• 10:00 – Returned to the room to pack.
• 11:00 – Checked out. We left our luggage at the front desk (they happily hold it for you!) and headed straight to Harunire Terrace.
• 11:30 – Re-visited the shops we liked the day before and bought the items we still wanted (I ended up buying a local dairy product gift set!).
• 13:00 – Had a nice lunch in the area.
• 15:00 – Picked up our luggage from the hotel and headed home!

This flow felt incredibly smooth and satisfying, so I highly recommend using it as a guide for your own trip!

Final Thoughts on Hoshinoya Karuizawa

To wrap things up, staying at Hoshinoya Karuizawa is truly a once-in-a-lifetime experience. Yes, it is a significant investment, but the level of meticulous Japanese hospitality (Omotenashi), the breathtaking harmony with nature, and the deep cultural history make it worth every single penny.

In fact, I recommend this resort so much that I, as a Japanese local, actually chose this exact place to propose! The atmosphere here is incredibly romantic and peaceful, making it the perfect escape from busy cities like Tokyo or Osaka. The memories we created here are something my partner and I will cherish forever.

If you are planning a trip to Japan and want to treat yourself to the absolute pinnacle of traditional luxury—or if you are looking for the perfect spot for a very special occasion—I highly encourage you to add Karuizawa to your itinerary.

When it comes to actually booking your stay, I strongly recommend using the official Hoshino Resorts website rather than third-party booking platforms. The official site not only has the most accurate room availability, but they also offer a fantastic early-bird discount if you book more than 90 days in advance! It is definitely the smartest way to secure your reservation and get the best possible value.
