In Japanese there is even a word for saying all the seasons as one word 春夏秋冬 （しゅんかしゅうとう） which is quite unique. What is great with this word is that if you memorize the word しゅんかしゅうとう, you get four seasons kanji with their onyoumi reading for free. That said, memorizing that word can be really useful for other words. Saying four seasons can be said with 四季 （しき）.
