Hiroshima vs Phnom Penh

Hiroshima

Hiroshima has a humid subtropical climate with four distinct seasons. Summers are hot and humid, winters are mild compared to northern Japan, and spring cherry blossoms and autumn foliage are spectacular. The rainy season (tsuyu) runs from mid-June to mid-July.

Phnom Penh

Phnom Penh has a tropical monsoon climate with two distinct seasons. It is hot year-round, with the wet season bringing daily afternoon downpours from May to October and the dry season offering lower humidity from November to April. Temperatures rarely drop below 25°C.

Hiroshima

Hiroshima has an extensive streetcar (tram) network — the oldest and largest in Japan — supplemented by buses and a good cycling infrastructure. The tram system connects the station to Peace Park, the castle, and the Miyajima ferry terminal. An IC card (ICOCA/Suica) works on all public transport.

Walkability: Hiroshima is very walkable within the central area. Peace Memorial Park, the Atomic Bomb Dome, Hiroshima Castle, and Shukkeien Garden are all within a 25-minute walk of each other. The flat river delta terrain and well-maintained sidewalks make walking easy. The Hondori shopping arcade provides covered walking in any weather.

Phnom Penh

Phnom Penh has no rail transit or formal bus network for tourists. Tuk-tuks, motorbike taxis (motos), and ride-hailing apps are the primary transport. The city is increasingly congested, and crossing busy roads requires patience and confidence.

Walkability: The central tourist area along Sisowath Quay and the Royal Palace district is walkable, but sidewalks are often blocked by parked motorbikes and street vendors. Heat makes walking long distances uncomfortable. The BKK1 neighborhood is pleasant for strolling with many cafes and shops.
