If you're looking for a fun event packed with historical charm, check out the Sakura Jidai Festival. The event has been running in this castle town for over two decades now, and includes a variety of ways to take a step back in time. Numerous cultural performances, opportunities to try on traditional samurai armor, Edo-period style stalls selling food and drink, and shuriken (sometimes known as "ninja stars") throwing games are just some of the highlights.
The festival is scheduled to take place right around cherry blossom season, so you can enjoy the best of the blooms during your visit.
