Nisei Week, the lovely Little Tokyo event takes place for it's 82nd time this Summer. Starting Aug 10th through the 18th. Throughout the week and weekend there's Japanese cultural touchstones to do, just like in any anime you've seen. The big highlights are the festivals, the Plaza Festival is next weekend Aug 17th-18th and the Grand Parade is this weekend on the 11th.
Yes, it's really 9 days, but Little Tokyo loves Engrish, so just roll with it.
Though the bigger festival is next weekend, this weekend you have the 2024 Natsumatsuri Family Festival at JANM with free activities and entry for everybody on Saturday Aug 10th.
The Nisei Week site is sadly, not perfect and a little hard to navigate, but try your best and head to Little Tokyo over the next two weekends for festivals and fun.
