The short answer
The worst time to visit Japan is three weeks long, not three months. Those weeks carry almost all of the national pressure on rooms and seats: New Year, Golden Week and Obon. What each one is, with its dates, sits on our month by month page. The table below adds the part those cards leave out, which is how fast the country goes back to normal on either side of them, and how little of a bad month is actually bad.

Most of the year is clear, and so is most of a bad month
The pressure is weekly, not monthly. Golden Week ends on May 5. By May 7 the onsen towns, the hot spring resorts that fill first, book almost normally again, and the rest of May books almost normally. Obon holds for 4 days in the middle of August; the second half of the month is one of the calmer stretches of the domestic year. The country restarts on January 4.
We would not move a trip out of August to avoid Obon. We would not avoid April either, and if you want the honest reason April is hard, it is the cherry blossom and not a holiday: the first week peaks in Tokyo and Kyoto, and no legislation is involved.

Obon is a custom, and it closes nothing by law
No statute shuts Japan from August 13 to 16. The Act on National Holidays sets the country’s public holidays, and those 4 days are not on it; the only statutory holiday that month is Mountain Day on August 11, which has nothing to do with Obon. What happens instead is an observance that a great many companies follow out of habit, and that habit is old enough and broad enough to move the country. Families go back to their home region, clean the family graves and light lanterns for the dead.
Because the dates are pinned to the calendar rather than to a weekday, the real congestion shifts every year: when August 13 to 16 falls midweek, a lot of workplaces bridge to the nearest weekend and the crush spills a few days either side, and when it lands on a weekend it stays tighter. Golden Week behaves in the opposite way, because its four holidays are statutory and one of them can trigger a substitute Monday.

What a quiet week on this table still hides
The calendar measures the country, and a country is not a town. It cannot see one city filling for its own festival, and Japan has thousands of those. Kyoto in the last week of November is heaving with no holiday anywhere near it, and a sumo tournament fills the hotels around the venue while the rest of the same city stays ordinary.
The table never tells you whether one room is free on your night. For that, look at the opening calendar of a ryokan, a traditional Japanese inn: those run on a schedule of their own, and the Kyoto page sets it out month by month.
What you can do today
- Find your dates in the table first. Outside the three big weeks, national pressure is not the thing working against you, and you can stop planning around it.
- If you land inside one of them, book much earlier than usual, accommodation before anything else.
- If your dates still move, shift by days rather than by months. Shifting 2 days onto the far side of Golden Week changes the price and what is left, without touching the rest of the itinerary.
- Treat the Obon shoulder as unknown. The 4 days are certain, the days around them depend on where the dates fall in the week that year, so a seat on August 11 or August 18 is not automatically safe.
