Jason-kun suggests we visit the Japan Pavillion and Mitsukoshi store at Epcot this Memorial Day weekend. Anyone up for a road trip?
Matsuriza (taiko drum group) plays several times throughout the day in the World Showcase.
Also there's a display in the Bijutsu-kan Gallery entitled "Spirited Beasts" that explains the folklore behind various Anime monsters (obakemono).
Then there's the 10,000 sq ft of retail space at Epcot's Mitsukoshi gift shop. Maybe you can find that tamagoyaki pan you've been searching for... ;o)
And finally, there are a couple of Japanese dining options in the park--a teppanyaki (Teppan Edo) and a contemporary/sushi restaurant (Tokyo Dining).
If we stay 'til after dark, it looks like the pagoda-style structure is illuminated really beautifully! 行きましょう。
