Go strawberry picking in a secret Oz themed greenhouse at Chiba’s Keisei Rose Garden Famous for its large variety of roses, the Keisei Rose Garden in Chiba prefecture is changing things up with a special strawberry picking event. Yes, you’re reading that right: strawberry season in Japan is actually in winter. The event takes place in a greenhouse in the backyard of the rose garden, which is not usually open to the public. The entire experience is themed on the story of ‘The Wonderful Wizard of Oz’. Participants are guided to the greenhouse by a gardener dressed as a ‘strawberry hunter’. Upon entering the greenhouse, you’ll be welcomed by a nearly 2-metre-tall puppet resembling the Tin Man of the original story. The puppet reveals the secret about special ‘Oz strawberries’ that are growing in the greenhouse, which are said to be ultra delicious.
