Português (PT)Where to go in 1月
北半球がもっとも寒くなる一方、東南アジアはベストシーズンです。そのため1月は他の月よりも行き先選びがはっきりしています。
1月は世界をはっきりと二分する時期です。一方でヨーロッパや北アジアの都市は寒く日照時間も短いため、美術館巡りや雪景色に向いています。もう一方では東南アジアや湾岸諸国、南半球が一年で最も過ごしやすい時期を迎えています。共通する難点は、新年の祝日直後にあたるため、乾季を迎えている旅行先では宿泊料金が月を通して高止まりすることです。
今月訪れるのに向いている8の場所
この月がデータプランに与える影響
この時期はいつも以上にデータを消費する要素が二つあります。ひとつは寒さの中での移動でバッテリーの減りが早くなり、スマートフォンの地図をより頼るようになること、もうひとつは休暇明けの空港で無料Wi-Fiが使い物にならないほど遅くなることです。オフラインの地図を用意し、出発前にプランを有効化しておけば、どちらも気にする必要はなくなります。
今月避けるべきこと
北ヨーロッパは日照時間が非常に短く、多くの屋外スポットがシーズンオフで閉まっている一方、南アジアの都市の一部は今月大気汚染の問題を抱えています。屋外活動を中心にした旅なら両方とも避け、南半球を選ぶとよいでしょう。
Thai holidays in January and what they do to fares
The Bank of Thailand's 2027 holiday list puts New Year's Day on Friday 1 January, and 31 December 2026 (a Thursday) is also a bank holiday, so most office workers get Thursday to Sunday off. Departures from Bangkok on 30 and 31 December and returns on 3 January are the most expensive seats of the season, because a whole country travels in the same four days.
After the first weekend there is no Thai public holiday until Makha Bucha in February, so mid-January is the quiet window: outbound fares to Japan, Korea and Europe usually ease once the new-year rush has flown home. The cabinet sometimes adds a special holiday at short notice; check the Bank of Thailand list again a few weeks before you travel.
Visa notes for Thai passport holders in January
These are the entry rules for the places this page recommends. Rules change, so confirm on the official page before you pay for flights.
- Japan: Thai ordinary passports are visa-exempt for short stays of up to 15 days; a longer trip needs a visa from the Embassy of Japan. Immigration rules: https://www.moj.go.jp/isa/index.html
- ASEAN neighbours such as Vietnam, Indonesia, the Philippines, Malaysia and Singapore admit Thai passport holders visa-free for short tourist stays; the permitted length differs by country, so check before a long trip, for example https://www.ica.gov.sg/enter-transit-depart/entering-singapore/visa_requirements or https://evisa.gov.vn.
- United Arab Emirates: check the entry rule for Thai passports on the UAE government portal; airlines with a UAE hub can also arrange visas. https://u.ae/en/information-and-services/visa-and-emirates-id
- New Zealand: Thailand is not a visa-waiver country, so Thai passport holders need a Visitor Visa. https://www.immigration.govt.nz/new-zealand-visas/visas/visa/visitor-visa
- Australia: Thai passport holders need a Visitor visa (subclass 600) before travel. https://immi.homeaffairs.gov.au/visas/getting-a-visa/visa-listing/visitor-600
- Anywhere else on this page: check the country's embassy in Bangkok or its official e-visa portal, starting from the Thai Department of Consular Affairs. https://consular.mfa.go.th

When to book for January
- For the new-year long weekend, Thai travellers who book in October or earlier usually have the widest choice of flight times; by December the cheap fare buckets on Bangkok to Tokyo, Seoul and Taipei are often gone.
- For a mid-January trip, booking six to eight weeks ahead is usually enough for Asian routes. New Zealand campervans and Australian beach towns need more, because it is their own peak holiday.
- If a visa is needed, the visa appointment sets the timeline, not the fare: book the appointment first and buy refundable or changeable flights only after it is confirmed.
- Buy and install the eSIM at home in the days before departure; most plans in our catalogue only start counting days on first connection at the destination, which the plan page states.
Data needs in January
A winter week in Japan or Korea with maps, translation and a few photo uploads a day usually fits in 1 GB a day or a fixed plan of around 10 GB; ski days add little because you are on the slope, not on the phone. Road trips in New Zealand or Australia need more, since navigation runs all day and motel Wi-Fi is patchy outside towns.
Where to go in 1月
1月はいつもより料金が高いですか?+
乾季を迎える渡航先であればイエスです。最良の天候がちょうど休暇シーズンと重なるためです。対照的にヨーロッパの都市は、月の最初の週を過ぎると価格が下がります。
初めての雪旅行はどこに行くといいですか？+
日本と韓国は初めての雪旅行にぴったりです。電車は時間通りに運行し、案内表示は英語対応で、都市からゲレンデまでの移動も短時間で済みます。
寒さはeSIMに影響しますか?+
プロファイル自体には影響しませんが、バッテリーには影響し、寒さの中では消耗が早まります。モバイルバッテリーを持ち歩き、バッテリー残量が少ない状態で作業しなくて済むよう、出発前にプランを有効化しておいてください。
Which January dates are cheapest to fly from Bangkok?+
Usually the second and third weeks, between the new-year return rush and any early lunar new year. In 2027 lunar new year falls on 6 February, so most of January sits outside it.
Do Thai passport holders need a visa for a January ski trip to Japan?+
Not for a stay of up to 15 days on an ordinary passport. A longer ski season job or stay needs the right visa from the Embassy of Japan.
Is New Zealand worth it in January for Thai travellers?+
The weather is at its best, but it is also local peak season, and Thai passport holders need a Visitor Visa. Apply early and book vehicles before flights fill.
Should I buy one eSIM for a Japan and Korea trip in January?+
If both countries are on the route, a Japan and South Korea plan covers both on one profile. If Korea is only a day or two, two country plans can work out cheaper; compare on the plan pages.
