Reports avarage Sakura blooming

Hi,
Can someone recommend anywhere I can see past year avarage blooming dates of sakura around Japan?

I know there are past reports on blooming but as far as I understand they do not point out "start" and "end" date and so on... And other than that I can only find forecasts...

And yes, I have already googled.

They do actually. read the reports of the places you want to visit. Usually the writer would talk about the blooming condition on that day.

I believe japan guide have at least 4-5 years of reports on popular sakura viewing sites.

This website has a huge amount of information about sakura, including average blooming dates.

I probably must have mssed it totally. All I can find however is reports of this year...

Oh my god... I am so sorry for missing that out. Well, I am sorry for not seeing that. I hope you dont think I am lazy asking. I must have been too frustrated trying to find the solution....

Japan Guide as mentioned, but the "official forecast" is for one type of cherry. There are more than 600 varieties and they bloom at different times (including autumn and winter).

I collected some of the various sources into a page at http://japancustomtours.co.nz/sakuraforecast.htm to help illustrate some of the differences and the length of the season.
