Tokyo is so wonderful that it attracts tens of millions of visitors - the sushi, the temples, the markets, the gardens. There are many reasons that Tokyo, the capital of Japan, attracts so many visitors - 30 million tourists in 2018, according to the tourism minister.

It's crowded. And with the 2020 Olympics coming to Tokyo, it's only going to get more so. Summertime draws the largest crowds, so the best time of the year to visit is between September and November or between March and April. (Winter isn't busy but it's cooler and less comfortable.)

Tokyo is a crazy mix of pop culture and ancient traditions. You can spend from dusk to dawn in the karaoke bars, or while away an afternoon in the East Gardens of the Imperial Palace. 

And while the beloved Tsukiji fish market - the spot where bleary-eyed tourists and serious fishmongers alike would arrive before dawn to ogle gigantic slabs of tuna - has closed, you can still check out the Toyosu Fish Market, which opened in October in east Tokyo and is twice the size.

Lesser-known Kusatsu Onsen lures mostly Japanese tourists

If you want the beauty and culture without the crowds, consider Kusatsu Onsen. The Japanese resort town, famous for its healing properties, is just two hours by train, then 25 minutes by bus from Tokyo.

This popular vacation spot for those who live in Japan, set 1,200 meters above sea level amid stunning mountain landscapes in Gunma Prefecture, doesn't appear to have been discovered by many outside of the country - yet. 

Besides soaking, you can hike, cycle and check out the wild animals, such as monkeys and rare Japanese antelopes. (If you arrive in the winter, you could go skiing at the Kusatsu Onsen Ski Resort in addition to dipping into the hot springs, which are open year-round.)

Cultural activities include a somewhat touristy 30-minute show called Netsu no Yu, where you can watch local women sing as they stir the hot springs to cool the water to bathing temperature.

You can also check out the straw and bamboo studios scattered throughout the nearby artist village of Takumi no Sato. And rather than staying in a hotel, consider booking a traditional Japanese inn, called a ryokan, with a private in-room onsen.

Pro tip: Don't shower after your soak. You'll be washing away all those possibly healing substances
