Public holidays at Seattle move this destination's year too little to make it a different answer, so the Tokyo page is the one of record. This one is kept for the distance and the flight it implies.

No fare history on SEA–TYO yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in US as well as at Tokyo, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

The year in Tokyo

Tokyo has a well-defined seasonal profile that aligns with typical climate norms. Visitors should be aware of the summer heat and potential typhoons during late summer.

Busiest
mid Mar to late May — Ideal spring weather and cherry blossom season attract tourists.
early Jul to late Aug — Summer brings many festivals and events, despite the heat.
Quieter, still good
early Jan to mid Mar — Winter is less crowded with better prices, though colder.
early Sep to late Oct — Fall foliage begins, making it a beautiful time to visit with moderate crowds.
early Nov to late Dec — Transitioning from fall to winter offers fewer tourists and holiday decorations.
Wet or stormy
early Jun to late Jun — rainy season, moderate
early Sep to late Sep — typhoon season, moderate
Worth timing for
Sakura Matsuri (Cherry Blossom Festival), March — High accommodation prices and potential crowding.
Sumida River Fireworks Festival, July — Increased hotel prices due to demand.
Watch out for hot temperatures in summer; typhoon risks in late summer; urban flooding during heavy rains

This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
