Here’s how to get to Kusatsu Onsen from Kyoto (or Osaka) the easy way!
During the middle of our previous Japan trip, we took a two-night pause in Kusatsu Onsen for some relaxation before heading to Tokyo. Before that, we were in Kyoto. Here’s a look at our journey from Kyoto to Kusatsu Onsen.
On our last day in Kyoto, we checked out of the hotel around 10am, which is a typical check-out time in Japan. Before leaving, we shipped our large suitcases ahead to our accommodation in Kusatsu, a really convenient option if you want to travel light. The overnight bus we were taking also had a luggage size limit, so we only packed a small overnight bag and left it at the hotel front desk to pick up later. Looking back, if I were to do this trip again, I would probably ship the big suitcases straight to Tokyo instead, since we were only spending two nights in Kusatsu.
I should mention why we decided to take an overnight bus. The main reason was simple. It’s a more straightforward trip, without as many transfers between different trains. It’s also a cheaper option, which never hurts! On top of that, I had never been on an overnight bus in Japan before, so I thought it would be a fun little adventure. And the best part? It gave us an extra full day to explore Kyoto.
How to Book
We booked our tickets one month in advance through the site 発車オ~ライネット, the English site is Japan Bus Online. We were traveling on a Sunday and took the 22:13 pm bus departing from Kyoto Station, Hachijo Exit, F3. I recommend boarding from this stop since it’s conveniently located within Kyoto Station, and there’s plenty to do in the area while you wait.
When searching for the express bus, make sure to select ‘From Kyoto’ (or Osaka) and ‘To Karuizawa, Nagano,’ because there is no direct bus to the Kusatsu Onsen bus terminal. This route, however, covers about 80% of the journey.

The bus fare varies depending on the bus company. Facilities may also differ by vehicle, but most buses are equipped with reclining seats, a toilet, air conditioning, and free Wi-Fi. When booking, make sure to check the signs to see which facilities are available on the specific bus. See below screenshot for reference.

Accepted payment methods include credit cards such as VISA, MasterCard, American Express, JCB, and Diners Club International.

Passing Time Before Boarding
If you have some time to spare before your bus, Kyoto Porta is a perfect spot.
This huge underground shopping complex sits directly beneath Kyoto Station, so it’s super convenient. There are plenty of shops to browse and restaurants to try.
If you love Japan’s mochi donuts, known as ポンデリング, I also recommend taking a break at Mister Donut – JR Kyoto Station Building Shop. It’s a cozy spot to rest, enjoy a sweet treat, and recharge before your overnight bus journey.


The Overnight Bus Journey
The bus ride itself was surprisingly pleasant. Everyone on board was very quiet, and most passengers were asleep, which made for a calm and relaxing atmosphere. The bus made a few stops at rest areas along the way before reaching Karuizawa, giving travelers a chance to stretch their legs.
The experience felt a bit like sleeping on a plane, but better, because the seats were separated, giving each passenger a bit more space and privacy.
From Karuizawa to Kusatsu Onsen
The bus arrives at Karuizawa Station at around 7:56 am the next morning. From here, we take the local shuttle bus to Kusatsu Onsen Bus Terminal. To catch the bus, head to Karuizawa Station North Exit, Platform 2.
Follow the signs for the shuttle bus or ask at the information desk if you are unsure. The shuttle buses to Kusatsu Onsen are clearly marked, and the staff can help point you in the right direction. Tickets can be purchased directly on the bus, with both cash and credit cards accepted, but IC cards are not.
The bus makes a few stops along the way, offering scenic views of the mountains and countryside, before arriving at Kusatsu Onsen Bus Terminal.


According to the latest Bus Time Schedule, the earliest departure from Karuizawa Station is 9:40 am. To pass the time, you can grab a coffee and some light bites at Akaneya Coffee Ekimae, a specialty coffee shop near the station. The prices are a bit higher than regular coffee, but the quality and taste make it worth it. I was pleasantly surprised!
