SEPTEMBER AT JIGOKUDANI · QUIET · 8TH OF TWELVE
Food in the mountains, less reason to come down
September is the last month before the park itself starts warning you off. The troop is well fed and under no pressure to visit the pool.
21.0 °C is the 1991–2020 mean for Nagano city at 418 m. The park is at 850 m and runs two to three degrees colder, so read it as about 18.0 to 19.0 °C. No snow falls in an average September in the city.
The April–October timetable. Food still plentiful in the mountains.

What the monkeys are doing in September
September is the last quiet month before the park starts warning visitors off. The mountains are still feeding the troop, so it has little reason to come down. The quiet part of the year. The air is warm enough on its own, so the pool is mostly empty — wardens sometimes throw food in to bring the troop down at all, and the ones that get in are mostly the young, playing.
In the warm months the monkeys are rarely in the pool — the air is warm enough on its own; wardens sometimes throw food into the water to encourage them in, and the ones that do get in are mostly the young, playing.
The park publishes a predicted time for the monkeys coming down from the mountain and asks visitors to check before traveling and again on the day, through its live cameras and social accounts — which is the only thing that answers «will they be there today», and it is free.
A tour cannot make the troop hungry
Read before bookingThe mountains are still feeding them. No amount of planning brings a monkey down to a pool it has no reason to visit.
NOTHING ON SALE CHANGES THIS Park staff work to attract the monkeys during opening hours, but the monkeys may not show up at all on certain days; appearances are particularly sporadic in autumn. Seven of the 21 tours on this site include the ¥800 (≈$5.1) gate fee in the price and the rest leave it at the gate; not one of them includes a monkey.
