Where to go in January? Quieter places in Europe and Japan

TL;DR

Of the 35 European countries we cover, January carried the smallest share of the year's 2025 tourist nights in Croatia (0.7%), Greece (1.1%) and Montenegro (1.4%). It was the quietest month of the year in 19 of them. In Japan, January was the quietest month in 16 of 47 prefectures. It was not the busiest month anywhere we cover.

How we picked the quieter places

For each country and prefecture, we took its 2025 nights at tourist accommodation and worked out what share fell in January. If a place's visitors were spread evenly, each month would carry 8.3% of its year. A share below that means January was quieter than that place's average month; above it, busier.12

This compares each place with itself, not places with each other: a low share is a quiet month for that place. For how each year looks in full, open the country or prefecture page.

Japan in January: every prefecture

Japan's figures come from a sample survey, and the gaps between prefectures are often smaller than its sampling error, so we list the prefectures alphabetically rather than ranking them.3

Blossom, autumn leaves and typhoons in Japan in January

Cherry trees usually start to bloom in January at the JMA stations for one prefecture: Okinawa (around 16 January).7

Over 1991–2020, no typhoon came within 300 km of a JMA weather station in Japan in January.8 Typhoons by region and month.

These are the Japan Meteorological Agency's 1991–2020 averages at one station per prefecture; each year's dates differ. See cherry blossom dates and autumn leaf dates for every prefecture.

What these figures cannot tell you

  • A share of each place's own year, not a crowd count. A low share means that month was quiet for that place. It does not mean the place had fewer visitors than somewhere else, and a small country's busy month can still be far quieter than a big country's quiet one.
  • Nights, not queues. A national or prefecture total cannot show crowding at one sight, beach or old town. Day trips do not count at all, because nobody stays the night.
  • One year. These are 2025 figures. Another year can differ, for example when Easter moves between March and April.
  • Japan's figures are a sample survey. The gaps between neighbouring prefectures are often smaller than the survey's sampling error, so we do not rank prefectures against each other.
  • No causes. Weather and holidays sit next to the tourism figures here, but the figures do not show that either makes a month busier or quieter, so we do not say they do.
  • We have not been to these places and make no judgement about which is better to visit.

Other months: February · March · April · May · June · July · August · September · October · November · December. Or open January in Explore.

Key takeaways

  • Lowest share of 2025 tourist nights in January, in Europe: Croatia (0.7%), Greece (1.1%) and Montenegro (1.4%).
  • January was the quietest month of the year in 35 of our 82 places.
  • January was not the busiest month anywhere we cover.
  • What we would skip: reading a low share as a promise of empty streets. It says January was quiet for that country or prefecture as a whole, not at any one sight.
