A premium Japanese ink line named after natural imagery: each color takes its name from a scene like moonlight, autumn leaves, or morning glory.

Paper & pairing
Warm tones (oranges, yellows, ambers) show strong contrast between light and dark areas of each stroke, which is part of why they're popular with broader nibs. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.
About Pilot Iroshizuku
Iroshizuku is Pilot's premium ink line, launched to critical acclaim in the early 2010s. Each color is named after a scene from nature, from moonlight (Tsuki-yo) to autumn leaves (Momiji).
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
