Translation guide
In Japanese, the most common word for rhododendron is ツツジ (tsutsuji), which refers to azaleas and many rhododendron species. For larger, evergreen rhododendrons, シャクナゲ (shakunage) is used. The distinction is based on plant type rather than strict botanical classification.
The most common everyday word for rhododendrons and azaleas in gardens, parks, and general conversation.

In everyday Japanese, ツツジ (tsutsuji) covers most garden azaleas and small rhododendrons. シャクナゲ (shakunage) is reserved for the larger, evergreen rhododendrons with thick leaves. If you're unsure, ツツジ is the safer, more common word.
Both ツツジ and シャクナゲ are usually written in katakana in modern Japanese. The kanji forms (躑躅 and 石楠花) are rare and may not be widely recognized.
