Yokohama Weather in June

Rainy-season days

June feels warm, damp and often grey in Yokohama. Highs reach 26°C, but humidity stays high, and rain falls on about half the days. The showers can interrupt waterfront strolls and views from the Landmark Tower, so keep outdoor plans flexible.

You can still enjoy indoor sights like the Cup Noodles Museum or Yokohama Museum of Art. Rainy afternoons also suit Chinatown's covered streets and a bowl of hot ramen. Skip long, exposed walks along Yamashita Park when steady rain sets in; the waterfront is less fun under low cloud.

June events

The Yokohama Port Opening Festival, or Kaikō-sai, takes place around June 2, marking the port's opening. Expect events around the waterfront, including the Red Brick Warehouse area. Rain can affect outdoor activities, so don't make the festival your only reason to visit.

Hydrangeas bring seasonal colour to places such as Sankeien Garden. Its paths are lovely after a shower, though muddy patches can make wandering less comfortable.

Crowds and local tips

June is usually quieter than cherry-blossom season and the autumn foliage months. It falls before Japan's main summer school break, so you'll generally find fewer family holiday crowds. Rain also makes it a lower-demand time than clearer months, though the Port Opening Festival draws local visitors.

If you hate crowds, choose a rainy weekday for Sankeien, then spend the afternoon around Minato Mirai indoors. For a handy wet-weather route, take the Minatomirai Line between Yokohama Station and Motomachi-Chūkagai; it puts Chinatown and the Cup Noodles Museum within easy reach of stations.
