Tokyo is in leeward slope.
the windward slope is wetter. the leeward slope is drier. source: geosystems sixth edition by christopherson, page 213 by: josephine
The windward side of a sand dune is generally gentler and more gradual, while the leeward side is steeper. This steep slope on the leeward side, often referred to as the slip face, forms as sand is deposited on the windward side and then cascades down the leeward side due to gravity. As a result, the leeward side typically has a more pronounced angle of repose compared to the windward side.
The leeward side of a mountain is dry because as air ascends the windward side, it cools and releases moisture as precipitation, leaving less moisture to travel over the mountain to the leeward side, resulting in a rain shadow effect. This creates dry conditions on the leeward slope of the mountain.
THE LEEWARD SIDE IS HOTTER
The windward slope of a mountain experiences a wet climate due to orographic precipitation. As moist air rises over the mountain, it cools and condenses, leading to cloud formation and precipitation. This process results in higher rainfall on the windward side, while the leeward slope, or rain shadow, tends to be drier. Consequently, the windward slope is characterized by lush vegetation and a wetter climate.
In general, most dunes have a windward side and a leeward side. The windward side is the side on which wind strikes the dune, leeward is the opposite side. The force of the wind will affect the sand on the windward side differently from the leeward side.
The difference is that windward gets more rain, is wetter, and is the side of the mountain that is closest to the ocean. On the other hand the leeward is the farthest from shore and is drier but still gets rain.
The windward slope of a dune is the side that faces the prevailing wind, where sand is eroded and transported up the slope. In contrast, the slip face is the leeward side, which is steeper and where sand accumulates after being deposited due to gravity. The windward slope is typically gentler and more gradual, while the slip face is characterized by a sharper angle, often around 30 to 34 degrees. Together, these features create the overall shape of the dune as they interact with wind patterns.
The prevailing winds will force the clouds to climb when they reach the mountain range. As the clouds rise they drop their moisture. So the windward side of the mountain will get rain, and the leeward side of the mountain will be drier.

I assume you are referring to a rain shadow desert but your question makes little sense as written. A rain shadow desert forms when a mountain range blocks the flow of moisture from reaching the interior of a continent. It forces the ran to fall on the windward side of the mountains and little moisture is able to cross the mountains to the leeward side. See the diagram above.
