Take the highway bus from Shinjuku if you want the lowest fare and the widest choice of departure times, and can accept some traffic risk on busy days. Take the Fuji Excursion train if you want a fixed arrival time, hold a JR pass, or are travelling on a weekend or holiday when roads around Mt Fuji fill up. Without a pass the train costs roughly double the bus ().

Kawaguchiko, on the north side of Mt Fuji, is the most popular base for a day trip from Tokyo. Two direct options leave from Shinjuku. Highway buses depart from the Shinjuku Expressway Bus Terminal (Busta Shinjuku) many times a day. The Fuji Excursion is a limited express train that runs straight from Shinjuku to Kawaguchiko a few times each morning, with every seat reserved.
Late autumn is one of the best times to go. Observation data cited here shows Mt Fuji is most often visible in the mornings and from November to February, which also means busier weekends around the lake. Your departure time, your budget and how much a traffic delay would cost you decide the choice.
| Your situation | Better starting choice | What to check before booking |
|---|---|---|
| Lowest fare, flexible about timing | Highway bus | Departure and return times after any timetable change |
| Weekend, holiday or autumn-leaf season | Fuji Excursion | Seat availability one month ahead |
| Holding a JR Tokyo Wide Pass | Fuji Excursion | Seat reservation before travelling |
| Holding a nationwide Japan Rail Pass | Fuji Excursion | Extra charge for the Fujikyu section |
| Leaving Tokyo after mid-morning | Highway bus | Last return bus to Shinjuku |
Mobile data helps on the day for checking bus delays, live Fuji cameras and local bus times around the lake. co:sim's Japan data-only eSIM plans cover that; they do not reserve seats or change timetables.
Highway buses to Kawaguchiko leave from Busta Shinjuku, above the south side of Shinjuku Station. This October 2026 guide lists a fare of about ¥2,200 one way, a scheduled journey of about 1 hour 45 minutes and dozens of departures a day starting from the early morning. Seats are reserved, and tickets go on sale one month ahead.
The scheduled time is the bus's weakness. It assumes normal traffic, and the road toward Fuji can slow down on weekends, public holidays and autumn-leaf days. The same guide suggests leaving Tokyo early and starting back before about 17:00 on busy days. It also notes that Shinjuku bus timetables change on 1 November, so check the operator's timetable for your exact date.
Buses have a luggage hold, so a suitcase is not a problem if you are moving on from Kawaguchiko. The fare advantage is real for groups: a pair of adults saves several thousand yen on a round trip compared with the train.

Highway buses to Kawaguchiko depart from Busta Shinjuku, above Shinjuku Station.
The Fuji Excursion runs directly from Shinjuku to Kawaguchiko over JR and Fujikyu tracks. This analysis gives a one-way fare of ¥4,200, made up of the ¥2,580 base fare and a ¥1,620 limited express charge. Every seat is reserved, and tickets go on sale one month ahead at 10:00 Japan time through JR East's booking site, ticket machines and offices.
The catch is the timetable. Under the schedule from March 2026, the same source lists four direct trains each way, with a fifth on some seasonal days. Departures from Shinjuku run in the morning, roughly 7:30 to 10:30, and returns from Kawaguchiko leave between about 14:00 and 17:40. The fastest trip takes about 1 hour 54 minutes, with stops at Tachikawa and Hachioji.
Trains do not sit in road traffic, which is the main reason to pay more. If you have a tight evening plan back in Tokyo, a fixed train return is easier to rely on than a bus on a busy Saturday.

The Fuji Excursion runs only a few direct trains each way, all with reserved seats.
Yes. With a JR Tokyo Wide Pass, the Fuji Excursion is covered in full; you only need to reserve a seat. With a nationwide Japan Rail Pass, the JR section to Otsuki is covered but the Fujikyu section is not. This breakdown puts the extra charge at about ¥1,770 one way, which is still cheaper than the bus.
Without a pass, the gap is large. The same source calculates a two-adult round trip at ¥16,800 by train against ¥8,800 by bus. If cost matters and you are travelling on a quiet weekday, the bus is the sensible default.
There is also a slower rail option: local and limited express trains with a change at Otsuki onto the Fujikyu line. This guide shows it can be cheaper or similar to the Fuji Excursion depending on the trains, but the change is awkward with luggage.
Book your seat as soon as your date is fixed, especially for the train or for weekend buses. Save the booking, the return departure time and the Kawaguchiko local bus routes offline. Check a live Fuji camera on the morning of travel; if the mountain is hidden, a later day may be a better use of the fare.
A co:sim data-only eSIM can be installed before you leave home so data works on the day. It provides data only, without a Japanese phone number, so keep your home SIM available for booking sites that send SMS codes, if your phone supports two lines.
Choose the bus or train that fits your date and budget first, then compare co:sim for the rest of your Japan trip.
The highway bus is better for most budget travellers, because it costs about half the train fare and runs many more times a day. The Fuji Excursion is better on weekends, holidays and autumn-leaf days, when road traffic can stretch the bus journey, and for JR pass holders.
This October 2026 guide lists the bus at about ¥2,200 and 1 hour 45 minutes scheduled, while this analysis gives the train at ¥4,200 and about 1 hour 54 minutes. The train runs only a few direct services each morning, so the bus suits a later start.
Yes. Every seat on the Fuji Excursion is reserved, and there is no unreserved car. Tickets go on sale one month before travel at 10:00 Japan time, according to this source, and popular dates sell out.
JR pass holders still need a seat reservation. Book through JR East's online service, a ticket machine or a ticket office. If you plan to return by changing at Otsuki instead, reserve that connection ahead too, because ticket sales at some smaller stations are limited.
The nationwide Japan Rail Pass covers only the JR part of the Fuji Excursion, as far as Otsuki. You pay for the Fujikyu section separately, about ¥1,770 one way according to this breakdown. The JR Tokyo Wide Pass covers the whole journey.
Even with the extra Fujikyu charge, a nationwide pass holder pays less than the bus fare. Reserve your seat before the travel day, because the train has no unreserved seating.
You will usually have mobile data in Kawaguchiko town and around the lake, which helps with local bus times and live Fuji cameras. Coverage on higher trails and at the Fifth Station can be weaker, so save your return booking and maps offline.
A co:sim data-only eSIM provides data without a phone number, calls or SMS. You can install it before the trip and use it all day. Compare the network and validity on co:sim's Japan plan page before choosing.

Travel TipsTake the Nankai Rapi:t if you are staying around Namba, Dotonbori or Shinsaibashi and want a reserved seat with luggage space. Take the JR Haruka if you are going to Tennoji, Osaka Station, Shin-Osaka or Kyoto, or you hold a Japan Rail Pass. The two trains end in different parts of the city, so your hotel decides the answer more than the fare.
Travel TipsBook a reserved seat on the Tokaido Shinkansen if you travel on a designated peak date, carry a large suitcase, travel as a group or board mid-route at Kyoto or Nagoya. A non-reserved ticket suits a solo traveler with light luggage who values the freedom to take any train that day. On peak dates JR Central sells every Nozomi seat as reserved, so a non-reserved ticket no longer buys a seat on the fastest trains ([JR Central](https://railway.jr-central.co.jp/nozomi/)).
Travel TipsChoose an overnight Ha Long Bay cruise if you can give the bay one night: you get sunset, a quiet morning and far more time on the water for roughly the same road journey. Choose a day trip if your Hanoi schedule is tight, your budget is fixed or you dislike sleeping on boats. Either way, the drive from Hanoi takes most of a morning, so a day trip buys only a few hours afloat ([Vietnam Tourism](https://www.vietnamtourism.com/en/ha-long-bay-day-trip-vs-overnight-cruise-which-is-worth-it)).
