Zuihoden Mausoleum in Sendai

A short, steep walk from a stop on the Loople tourist bus, you'll find Zuihoden, the mausoleum for the samurai family belonging to Date Masamune, the founder of Sendai. The surrounding area is flush with a lovely old forest featuring trees older than some first-world countries. If you're a fan of architecture, the buildings within the main area will probably be more interesting and display colorfully painted intricate carvings prominently. For just 550 yen for adults, 400 yen for students (high school or younger) you can tour the grounds at your own pace and explore the small museum. Most of the artifacts inside relate very limited English, but still can be enjoyed easily as many of them are beautiful beyond easy description.
If you're planning a trip, go early as the PLACE is only open from 9AM to 4:30PM from February to November, closing half an hour earlier the other two months of the year. Also, wear good walking shoes. The up-hill jaunt is a bit of a workout if you're not used to climbing up
