Near my house, I found one cherry flower. Looks like we can have a cherry picnic in this weekend.
4 words phrase "San-Kan-Shi-On" represents this time of season. San is 3. Kan means cold. Shi is 4, and On means warm.
Thus, it means, we have three cold days and four warm days, which tells it is getting warm day by day and spring is coming.
