What April Feels Like
April is the big one. This is the cherry blossom season everyone pictures when they think of spring in Japan, and for a couple of weeks the whole country is in bloom at once. Parks, castle moats, riverbanks, whole streets go pink and white, and there's a buzz in the air you don't get any other time of year.
What makes it special is how social it all is. Everyone heads outside for hanami, friends, families, whole offices staking out a spot under the trees with food and drinks and staying for hours. It's less about quietly admiring the blossoms and more about celebrating that spring's finally here, and getting swept up in that is half the fun of visiting in April.
Why April Can Be a Great Time to Visit and How to Plan It
If seeing Japan at full bloom is the whole reason you're going, April is it. The blossoms that started in the warmer cities in late March sweep north through the month, so you can either chase the season across a few regions or time one destination to hit peak bloom. Hit Hirosaki Castle in Aomori, Kakunodate in Akita or the big Kyoto spots at the right moment and you'll see exactly why Japan in spring gets the reputation it does.
But the problem is everyone else has the same idea. April is usually the busiest and priciest month of the year. The famous spots get packed, especially on weekends, and if crowds are a dealbreaker you might be happier in late March or May. But if the blossoms are the point, it's worth every bit of it.
Rooms in the big blossom spots, Kyoto, Tokyo, Hirosaki, Kakunodate and the Fuji Five Lakes, book out months ahead for the peak weeks and hit their highest prices of the year. Book as early as you can, six months out for Kyoto and the popular spots isn't overkill. Same goes for the shinkansen. You can always jump in the unreserved cars, but in April you'll likely be standing unless you reserve a seat or line up early at the starting station, so it's worth booking ahead.
For pacing, two weeks is ideal if the blossoms are your focus. Start in Kansai where they're usually at or just past peak in early April, work through Chubu and Kanto mid month, and finish in Tohoku where the season peaks late, so you will never miss out on seeing the cherry blossoms. For one week, pick a lane, either Kyoto and Kansai for the classic settings, Tokyo and Kanto for the city version with easy access, or Tohoku in the second half for the castle and riverside festivals at their best, and with far fewer crowds. Have a look through the spring destination guides to see what's on where you're headed.
April Weather and What's in Bloom
April weather is mild and gets warmer as the month goes on. Tokyo and Kyoto sit around 10 to 18 degrees, and the milder Inland Sea areas like Hiroshima and Takamatsu are comfortable for being outside all day. Down in Kyushu it's properly into spring by mid April, while Sapporo is only just warming up into the low teens. By the end of the month everywhere bar the far north is warm. Rain's possible but the rainy season hasn't started yet, so most days are fine for being outside. The one thing to watch is a bad combo of rain and wind during blossom week, which can strip the petals early, so keep an eye on the forecast and save your outdoor days for when it's clear.
The bloom moves north as the month goes on. The warmer cities peak in early April, Tohoku catches up mid to late month, and Hokkaido brings up the rear in late April into early May, the last place in the country to bloom. So if you miss the blossoms down south, you can head north and catch them again.
Just to note, it's not spring everywhere. The mountains and highlands are still cold, and the ski resorts up in Hokkaido and northern Nagano are running into April. Handy to know if you want to pair blossoms with a bit of late season snow, which April is one of the few months you can actually pull it off.
