This information will be included in the General Guide as well as Calendar Guide, but I thought it might be useful for players who are beginning the game.
The Cherry Blossom Festival in Tides of Destiny follows the RFF tradition of including little mini-games in the celebration. If you do not know this, you may waste a day fruitlessly simply talking to all the Villagers about the flowers.
Although Odette will tell you early in the morning that there is 'something I need to do first' before the festival can begin, you will not be able to gain any more details until later in the day.
The actual Festival mini-game appears to begin at noon, when you must speak to James. Only James will offer the prompt to allow you to speak to Odette to obtain the list of ingredients you need.
You will find Odette again in her kitchen. She will give you a random list consisting of three ingredients she needs in order to be able to make the feast for the Festival. The ingredients appear to change from game to game, but the Characters who have them always were James, Electra and Bismark in my experiences.
You need to speak to each of these three Characters. James will be at his Stall in the Plaza Paviliion near the Church. Electra should be near her Mansion. It was Bismark who was annoyingly evasive in my game. Every time I reloaded, I failed to find him until it was close to 5.00 p.m. when he appeared again outside the Gemini General Store. If any one knows where he is between 1.00 p.m. and 4.00 p.m., please share, simply for my own satisfaction as even at 4.45 p.m., you still have time to obtain his ingredient and give it to Odette across the road.
Odette then will make a Dish out of the Ingredients she requested. From Bread, Curry Powder and Oil, for example, she made Curry Bread. She then will give you the Cooked Dish.
That is the Cherry Blossom Festival. The actual Blossoms float through the air throughout the Village, but Villagers appeared to wander from screen to screen throughout the day speaking of them. I had expected some congregation of Villagers at some point, but this did not occur. The Festival appears to consist mainly of dialogues about flowers and the mini-game.
It is possible that I may have missed some grand event somewhere, but I did comb every screen at all times of the day rather religiously, so...
