賞螢火蟲
初夏的夜晚，河邊飛舞著點點微光。觀賞期大約在5月下旬至6月，無風而悶熱的夜晚8點到9點左右最佳。請不要用光照射、不要捕捉，安靜地觀賞。
出行小提醒
- Viewing is at night, so check the time of your last train or bus back first.
- Weekends are very crowded, and some places, such as Maibara, ask visitors not to come by car. Trains and buses are the safer choice.
須知事項
Viewing rules
- Do not point torches, phone lights, camera flashes or car headlights at the fireflies. They signal to each other with light, and stop glowing when lit up.
- Do not catch them or take them home. Adults live only a week or two, in which they produce the next generation. Some cities, such as Maibara, ban catching them by ordinance.
- Stay out of the undergrowth. It is dark, the footing is hard to see, and there may be dangerous creatures.
- Watch quietly, drop no litter and do not park on the road. People live nearby.
- Some places, such as Tatsuno, ban tripods in the busy period. Follow the notices on site.
When and in what weather
- Genji fireflies fly from roughly mid-May to late June (Kitakyushu). In Tatsuno, Nagano, the peak is early to mid-June. In the hills the peak comes a little later than on the plains.
- They are most active for about an hour after dark, around 8 to 9 p.m.
- They fly little in rain, strong wind or on chilly nights. A warm, humid, still night is best.
- Fireflies are wild, so the timing shifts from year to year. Check the local government's emergence reports before you go.
