Mother's Day in Tokyo: red for Haha no Hi, and the flowers that carry it
Mother's Day in Tokyo follows Haha no Hi, the second Sunday of May, and the flower of the day is the red carnation: a white carnation is tied to the memory of a mother who has died, so it never goes to a living one. That same red carries through here in roses, in lilies paired with gerbera and in blue hydrangea, rather than in the carnation itself.
Red for a living mother: the colours of a Haha no Hi bouquet
The Japanese custom is simple to state: red stands for a mother who is still here, white for one who is remembered. White chrysanthemums carry the same weight all year round, since Japan keeps them as a funeral flower and never sends them to someone living. A bouquet for Haha no Hi starts, then, with the colour it leans towards rather than with which flower fills it.
That leaves plenty of room. The section pairs lilies with gerbera for a bright, open shape, sets blue hydrangea against sprays of misty for something softer, and keeps red roses for the colour the day is actually about. None of that rules white out on its own: if white goes in, let colour lead the rest of the arrangement rather than carry it alone.

Where the day calls for red and no carnation is on offer, a red rose bouquet stands in for it comfortably; the Red Rose Bouquet "Naomi" is built on exactly that colour. The same red also comes as eleven French roses, gathered plainly rather than shaped into anything elaborate. "French" names a technique here, not a variety: the florist turns the outer petals back by hand so the bloom opens wider than it would on its own.
For something softer, fifteen French roses make up the "Jumilia" bouquet, with a larger bud, up to about seven centimetres across, pale at the base and edged in pink rather than solid through. Stem counts follow their own small customs in a Japanese gift: four and nine are numbers many people steer around, one detail among the wider Japanese gift customs worth a glance before you settle on a total.
A box, a basket or a pot that needs nothing from her cupboard
A hat box or a designer box arrives ready to stand on its own, so there is no vase to hunt for in a cupboard that might not have one. A basket works the same way: the stems sit in foam soaked with water, and keeping them going is a matter of watering that foam in a thin stream over its whole surface every day, not topping up a container from above.
A plant in a pot suits a home where it can stay for good, but it is not what goes to a hospital room. In Japan a potted plant reads as a wish that someone will "take root", which is the last thing a hospital stay is about, so cut flowers travel there instead, never a pot. A box or a basket covers a bedside table and a front hall equally well, wherever the delivery is headed.

The Sunday after Golden Week: booking her flowers ahead
Golden Week runs from 29 April through the holidays of 3 to 5 May, and Haha no Hi always lands on the Sunday after it, the second Sunday of the month. That makes the date easy to miss and easy to plan for in the same breath: never far from the start of May, yet never inside the Golden Week break itself.
Mother's Day flower delivery in Tokyo gets busier than an ordinary weekend, and the delivery page sets wider windows for that Sunday rather than promising an exact minute. Booking a date and time ahead, in any zone, is the way to hold a slot before they fill. The florist photographs the finished bouquet before the courier sets out, and a card with your own words is added at no extra cost. For something beyond flowers, a balloon such as "To My Beloved Mom" goes into a basket alongside them, picked among the gifts that go with a bouquet.
Choosing for Mother's Day in Tokyo comes down to colour first and container second: red for Haha no Hi itself, a softer pink beside it, and a box or basket if there is nowhere at home for a vase. The full range of reds sits on the roses page, and where lilies, hydrangea and roses are combined rather than kept apart, the mixed bouquets selection is the place to start.
