Should I book a reserved seat on the Shinkansen?

Yes, according to almost every Japanese rider in these threads. Unreserved cars are shrinking, they overflow into the reserved cars in peak season, and the one rule regulars give for riding unreserved is to board at the origin station where the train starts empty.

Do I need to reserve space for a large suitcase?

On the Tokaido, Sanyo and Kyushu Shinkansen, bags over 160 cm in total dimensions need a seat with oversized-baggage space, reserved at no extra charge. Japanese commenters are blunt about people who skip the reservation and dump bags there anyway: tell the conductor immediately, and they want JR to enforce it.

Shinkansen (Japan's Bullet Trains): What Locals Actually Say

新幹線

Eight roundups from Japanese comment threads, 4,832 comments with 140 translated, and the through-line is that riders want the rules enforced, not relaxed. The most-liked comment (1,124 likes) calls it the great irony of the Shinkansen: the trains keep getting better while the passengers get worse. The practical consensus underneath it: book a reserved seat, reserve the free oversized-luggage space instead of dumping a bag in it, and if you must ride unreserved, only ever board at the origin station (519 likes). On the JR Pass after the price rise, and on whether station bento are still worth it, the threads split.

The greatest irony: the quality of the trains keeps improving while the quality of the people riding them keeps dropping.

Back when the Tokaido Shinkansen had dining cars, people who couldn't get an unreserved seat would apparently order the cheapest dish and camp there for the whole ride.

This has the same smell as people parking in your spot without asking.

I love the travel feeling of the night bus so I end up taking it every time. The moment you board with that late-night buzz is the best part. The dawn air when you arrive at your destination tastes so good

People who board with an unreserved ticket, find no seats, and just plant themselves in a reserved car. People who tell a seated passenger to give up their seat because their kid looks tired. Full unreserved cars cause way too much trouble.

I'm a night bus lover, but a four-across seat with someone next to you and no curtain is rough, I'll admit

The real problem with unreserved seating: in peak season, the overflow floods into the reserved cars and stands in the aisle. And those standees wedge their rock-hard suitcases against the knees of people like me who are sitting there. A punishment I paid a reservation fee to receive. All-reserved trains killed that alone, and it's heaven. Thank you, JR.
自由席の難点はシーズン期に自由席からあふれた客が指定席に押し寄せて立ち客になる事。その立ち客はとっても堅いキャリーケースを座っている私のヒザ元に押し込んでくるのさ。指定席料を払って受ける罰ゲーム。全席指定でアレが無くなっただけでも天国さ。ありがとうございますJRさん。

What you can actually do, right now, is tell the conductor immediately.

Night bus. The Hakata-go, 15 hours from Hakata to Busta Shinjuku. I recommend the four private premium compartments. I'm boarding from Hakata on the 27th of next month.

These days an ekiben is something you buy at a department-store food fair and eat at home. When you actually board a limited express or a Shinkansen, what you pick is an onigiri or a bento from the convenience store in the station. Of the fair-priced ekiben I bought at those events, the ones I still remember for taste are Yokokawa's kamameshi, Mori Station's ikameshi and Takasaki's daruma bento.
いまや駅弁は百貨店の催事場で買って自宅で食べるものになっている。いざ特急、新幹線に乗る時に選ぶのは駅内にあるコンビニで売っているおにぎりや弁当になる。催事場で買った手頃価格の駅弁でいまだに美味さが記憶にあるのは横川の釜めし、森駅のいかめし、高崎のだるま弁当あたりかな。あと新幹線にビュッフェがあった頃、たまに食べたカレーライスはなぜか美味しく感じたな。

Places named across these roundups

Hiroshima AirportMihara, Hiroshima Prefecture
The airport in the thread's crosshairs. No rail link; the limousine bus from Hiroshima Station is about 50 minutes for 1,500 yen and runs on the expressway, which is why commenters call the arrival time hard to predict (62 likes). Fog cancellations are a seasonal risk (30 likes).
Sources: hij.airport.jp
Iwakuni Kintaikyo AirportIwakuni, Yamaguchi Prefecture
The instead. Fewer Haneda flights, but the connecting bus from JR Iwakuni Station's east exit is 7 minutes and 200 yen, and it pairs neatly with a Miyajima day (21 and 19 likes).
Sources: iwakuni-airport.jp
Shiraichi StationHigashihiroshima
The JR back door to Hiroshima Airport, 13 to 15 minutes away by connecting bus. Commenters are split on it: it avoids the expressway, but one warns the local line itself is prone to delays (62 likes).
Sources: hij.airport.jp
Hiroshima Bus CenterNaka-ku, Hiroshima
The other limousine departure point, in the middle of the shopping district rather than at the station. A Hiroshima commenter (46 likes) points out the two stops run roughly equal numbers of buses, so there are more departures than the timetable at the station suggests.
Ekibenya Matsuri (Gransta Tokyo)Tokyo Station, inside the ticket gates on the Central Passage
Named in the thread as where one rider buys bento when there is time, with a station convenience store as the fallback (10 likes). JR East Cross Station lists it inside the gates on the Central Passage, open from 5:30.
Sources: gransta.jp
Oginoya Yokokawa Main Store (Toge no Kamameshi)
The clay-pot kamameshi named twice in the thread as a survivor. Sold at the Yokokawa main store and, as commenters note, at expressway service areas — one of the ekiben that found a second door (confirmed operating as of mid-2026).
Ikameshi Abe Shoten (Mori, Hokkaido)
The stuffed-squid ekiben from Mori Station, made since 1941. Commenters say to buy it at a department store's Hokkaido fair instead — the maker's own account matches: platform selling at Mori Station is down to roughly two weeks in midsummer (as of mid-2026).
Sources: ikameshi.co.jp
Kiyoken (Shiumai Bento, Yokohama)
The box the thread uses as its price benchmark. It crossed ¥1,000 in February 2025 (¥950 → ¥1,070) and rose again in February 2026 (as of mid-2026) — the moment one 233-like comment calls "the era turning."
Sources: kiyoken.com · kiyoken.com
Shinkineya (Gyuniku Domannaka, Yonezawa)
The Yonezawa beef bento a commenter names as surviving via the local michi-no-eki. The maker's shop is by Yonezawa Station's west exit, and the bento is also carried at stations along the Tohoku Shinkansen (as of mid-2026).
Minamoto (Masu-no-Sushi, Toyama Station)
The trout-pressed sushi one commenter loves but has stopped buying on price. Sold at the Toyama Station shop by the central gate, inside the Toyamarché complex a commenter mentions (as of mid-2026).
