Sakura 2018 forecast

There is a 1 week difference in the first bloom and full bloom dates posted by japan metereological corporation (JMC) and japan weather association for sakura 2018. E.g. as per JMC the full bloom in tokyo is 22nd march and as per Japan guide website it is 29th march. Which of these forecasts is more accurate? My travel dates are as below
1-7th april-tokyo
8-12th april-kyoto
13-15th april-osaka
Would we be able to see full bloom in tokyo?

22 march is opening
29 march is full bloom

two different things...

22 march is opening
29 march is full bloom

I thought the same, but no, both are for the full bloom.

I think no one can judge which is more accurate. They are just prediction. This year winter was cold and early spring is warm both of which makes the bloom early, so the blossoms will bloom earlier than the normal year. I am afraid it will be rather likely that Tokyo's Someiyoshino will be gone by early April. The OP might better go some colder place to catch Someiyoshino full bloom.

You know what "PLAY" button is.

Also you can search by Twitter, FB, instagram..., though.

BUT, blooming forecast will be revised after this, so no need to worry from now.
It can not be said that we saw the best cherry blossoms
unless we had fine weather during a short full bloom 3 to 5 days.
Full blooming(満開 mankai) start date is not "first bloomig(開花 kaika)" date.
Blooming forecast date is NOT "full blooming" date, don't make a mistake.

The expected date differs because the reference "standard trees" are different.
The highest institution of Japan's meteorological observation is "JMA",
the info you wrote is a private weather companies one,
so they watching own selected another standard trees.
"WNN" is also one of them and also based 5000+ "My Sakura" users
and daily posted live reports nation wide.
This is one of user report with pics, in Tokyo near Meguro river.

This is JMA records of full blooming start date.

It will be difficult to understand, bc without map.
(use Google translate)

"SomeiYoshino" is most famous(also top numbers of tree) species name,
and selected "standard tree" of blooming forecast.
The type of Sakura tree is said to be "500+",
but there are few people who can say more than 10 kinds even in pure Japanese.
It is more than 95% of the total with only SomeiYoshino and several species.

Although not conscious of much, Sakura is biologically a relative of "Rose",
breeding continues not only for wild species but also for ornament.
So SomeiYoshino is most successed tree as a result of breeding, born in about 150 yrs ago.
However, it is young as a history of tree, and have weak points as tree life. (not flower life)

Anyway, no one knows the best timing until just before.
Even in the same area and same species, it will bloom earlier in sunny places,
otherwise it will bloom late, nothing you cannot see.

Blooming forecast date is NOT "full blooming" date, don't make a mistake.

Yes, but who made a mistake?

Thank u so much for the guidance. We are going to try and cover the major locations in tokyo - meguro river, chidorigafuchi, imperial palace gardens, shinjuku gyoen, ueno on 1st april and see if we are lucky for the full bloom of someiyoshino. I would follow JMA website for the future forecast as mentioned by a fellow reader. Keeping my fingers crossed. I have also downloaded " sakura navi" app to keep track of the flowering region wise.
