The ticket can also be purchased from discount ticket (金券 kinken) shops at a small discount (typically ¥300–500). These shops often offer partially-stamped tickets, as well, for those who may not want or need the full 5 days, or who need only a couple of extra on top of the 5 provided by the standard ticket. Expect to pay a higher per-day price when buying a partially stamped ticket – it can go as high as ¥3,500 for a ticket with one day left. The price slowly goes down toward the end of the effective period, e.g. ¥2,000 three days before expiration. Additionally, these shops are all cash-only.

You may also sell partially stamped ticket to these shops – get several thousand yen back and help another budget traveler. The sooner the better, because of price erosion and possible rejection; shops stop buying tickets about one week before expiration. However, you will need the help of a Japanese citizen or resident as non-residents are not allowed to sell to ticket shops.

The Tokaido Line is undoubtedly the easiest line to travel with a Seishun 18 Ticket, and probably one of the most convenient for tourists because it forms the shortest link between Tokyo and the Kansai region. Trains run every 15 minutes or so during the day, making it easy to take breaks en route without running over schedule. It takes about nine hours to get from Tokyo to Kyoto, not including rest or meal stops; this requires about 4-6 transfers along the way depending on when you travel. These transfers will most likely occur in cities such as Atami, Shizuoka, Hamamatsu, Toyohashi, Ogaki, and Maibara. From Maibara, you can go north to the Hokuriku Region or continue west. There are trains that run all the way from Maibara to Himeji and Banshu-Ako (Ako) on the Sanyo Line. Tokyo to Nagoya takes about 6 1/2 hours without stops.

The Sanyo Main Line is the westward extension of the Tokaido Main Line, connecting the Kansai region to Okayama, Hiroshima, and Kitakyushu. It is not quite as convenient as the Tokaido Line, but generally runs at least every half hour (with frequent service around Kobe, Hiroshima and Fukuoka). Shin-Kaisoku Trains can travel from Maibara (on the Tokaido Main Line) all the way to Himeji before a transfer is necessary. Osaka to Hiroshima is about 6 hours; Hiroshima to Fukuoka is another 6 hours.

Those wishing to visit Shikoku must transfer at Okayama to the Marine Liner. The Liner is covered by the pass, as long as you remain in the non-reserved section. The Yosan Line, Yodo Line, and Dosan Line travel in a circle from Kagawa to Ehime (Yosan), Ehime to Kochi (Yodo), and Kochi through western Tokushima and back to Kagawa (Dosan). The Uchiko Line in Ehime is the only additional line along the route and provides access to the historic town of Uchiko. Many Seishun travelers use this as their "Golden Route" around Shikoku to visit the most famous locations, such as Takamatsu, Matsuyama, Uwajima, Kochi, and the Iya Valley as a single Shikoku Seishun 18 trip.

Additionally, the Tokushima Line connects Awa-Ikeda Station (Miyoshi) to Tokushima, the Kotoku Line connects Takamatsu to Tokushima, and the Mugi Line gives access to southern Tokushima Prefecture from Tokushima City. The Kuroshio Railway lines in Kochi Prefecture are private railways not covered by the pass.

Trains in Shikoku are less frequent, so it's important to plan ahead and be aware of train times when traveling to multiple cities around the island. The Yodo Line between Ehime and Kochi is particularly sparse of options. Missing your connection could leave you stranded for hours waiting for the next train.

The Chuo Main Line is a Y-shaped line through the Japanese Alps, connecting Tokyo and Nagoya via Shiojiri. Although the Chuo Main Line can be used for travel between Tokyo and Nagoya, the Tokaido Main Line is faster. The corridor between Kofu and Nakatsugawa are very rural, so train connections are infrequent. Because of this, the Chuo Main Line is only recommended over the Tokaido Main Line for those who plan to stop at locations along the way or those wishing to travel travel further north to Matsumoto and Nagano, which can both be reached by transferring to the Shinonoi Line at Shiojiri. You can reach Nagano from either Tokyo or Nagoya in approximately 6 hours.

Since the opening of the Hokuriku Shinkansen in March 2015, and extension to Tsuruga in March 2024, local and rapid trains in the area are now almost entirely run by private railways. The Hokuriku Main Line now only runs from Maibara to Tsuruga; from Tsuruga all the way to Naoetsu, trains are run by various companies. The privatization of most of the area has left a few JR lines disconnected from any connections with a JR station. Deals were reached with these private railways to allow passengers to use their lines without charges only when exiting at stations where a JR transfer can be made (Echizen-Hanandō Station for the Kuzuryū Line a.k.a. Etsumi-Hoku Line, Tsubata Station for the JR Nanao Line, Takaoka Station for the Himi and Jōhana Lines, and Toyama Station for the Takayama Line). If you get off at any station that does not have a JR connection, you will be charged for the route traveled.

The Tohoku Line follows the Pacific coast north from Tokyo to Sendai and Aomori. It is about 7 hours from Tokyo to Sendai, and another 9 hours from there to Aomori. Outside of the Tokyo and Sendai metropolitan areas, services are relatively infrequent, running on an hourly or bihourly basis.

To travel to Hokkaido, you must purchase a ¥4,500 "option ticket" described earlier in this article which will grant you access to the Hokkaido Shinkansen for only the segment through the Seikan Tunnel.

Be warned that the train schedules in northern Japan, particularly in Hokkaido, are very limited. You'll want to use a timetable or sites like Navitime, Jorudan, or Yahoo! Transit to plan your itinerary. If traveling between Aomori and Sapporo, you can expect the trip to take two days.

Here are some of the basic routes to use from Sapporo down to Hakodate, Aomori and Niigata:

• From Sapporo to Hakodate, take the Chitose Line to Tomakomai (1.5 hours), then the Muroran Line to Oshamambe via Higashimuroran (just over 3 hours), then the Hakodate Line to Hakodate (about 4 hours).
• From Hakodate to Kikonai, take the private South Hokkaido Railway Isaribi Line, covered by the option ticket (1 hour).
• From Kikonai to Shin-Aomori, which is only served by the shinkansen, the option ticket permits you to take any available standard class seat on the Hayabusa or Hayate service (50 minutes). There are eight daily round-trips that operate between the two stations at about 2–3 hour intervals. At Shin-Aomori you can take any Ou Line train, including limited express trains, for the short 5-minute journey to Aomori station in Aomori city.
• From Aomori (or Shin-Aomori) to Akita, take the Ou Line via Hirosaki, Odate, and Higashinoshiro (1 hour to Hirosaki, 2.5 hours to Akita). You may have an extended layover at Hirosaki depending on your schedule.
• From Akita to Niigata, take the Uetsu Line to Shibata via Sakata and Murakami (5 hours), then change to the Hakushin Line for Niigata (30 minutes).

JR West Bus (West Japan JR Bus Company), the bus department of JR West, gives passengers who have Seishun 18 Tickets a discount on fares of three bus routes: the Meikin Line (名金線 Meikin-sen) between Kanazawa Station and Fukumitsu, the Enpuku Line (園福線 Enpuku-sen) between Fukuchiyama Station and Sonobe, and the Wakae Line (若江線 Wakae-sen) between Ōmi-Imazu Station and Obama Station. Through this campaign, passengers may ride on the above bus routes at a flat fare of ¥800 each.

Passengers must show the bus driver their Seishun 18 Ticket, are given a discount ticket at the end of their ride, and may only alight at the two terminal stops of each line. Alighting at any other stop results in no discount being applied.

On the Hisatsu Orange Railway, the Orange 18 Free Ticket (おれんじ18フリーきっぷ Orenji jūhachi furī kippu) is sold for ¥2,100 to passengers who have valid Seishun 18 Tickets in a valid period of time (a same-day seal is placed on the ticket).

The Hokkaido and East Japan Pass (北海道&東日本パス Hokkaido & higashi-nihon pasu) is a regional version of the Seishun 18 Ticket, priced slightly cheaper at ¥11,330 (children ¥5,660) for seven consecutive days of travel. The pass allows travel on all JR East and JR Hokkaido local and rapid commuter services, plus the Iwate Galaxy Railway (IGR a.k.a. Iwate Ginga Tetsudo) and Aoimori Railway (Aoimori Tetsudo) lines between Morioka and Aomori, along with the Hokuetsu Express between Echigo-Yuzawa and Naoetsu. With the purchase of an additional special express ticket (特定特急券 tokutei tokkyuūken), trips are also permitted on Hokkaido Shinkansen trains between Shin-Aomori and Hakodate), sold as standing room (立席 tachiseki) tickets where riders may use any available seat in the specified car.

The Aki no Norihōdai Pass (秋の乗り放題パス), the "Autumn All-You-Can-Ride Pass", can be used in precisely the same way on precisely the same lines as the Seishun 18 Ticket. However, it's available only once a year for a two-week period in early October (exact dates vary yearly), and tickets go on sale in mid-September. The cost is ¥7,850 for three days, making it cheaper per day than the three-day Seishun 18, and unlike the Seishun 18, a half-priced version for kids is also available. The ticket is sold every year to commemorate Railroad Day (鉄道の日 Tetsudō no hi) which is celebrated on October 14. Like the above tickets, an "option ticket" may also be purchased to ride the Hokkaido Shinkansen for an extra fee. This pass also gives JR hotel discounts as described above.

The Aki no Norihōdai Pass 2024 dates are as follows:
