Summary

About 2,200 fireworks rise over the small Kojiri Bay on the north side of Lake Ashi for 20 minutes from 20:00 on August 4, held as the Ryujin Festival honoring the lake's guardian deity, Kuzuryu Okami — night five of the Lake Ashi Summer Festival Week. The enclosed little bay bounces light and sound off the surrounding mountains for a feel unlike the other lake displays. The shrine rites held by day are not open to the public; the show is the public part. Kojiri is about 45 minutes by bus from Hakone-Yumoto Station.

Overview

Kojiri is a quiet stretch of shore on Lake Ashi's north side, where the fireworks follow the shrine rites at Kuzuryu Shrine — rites that are not open to visitors, so the evening display is what the public comes for. The small bay gives the 20-minute show a concentrated acoustic character, the 2,200 shells echoing off the mountainsides. The week's fifth night falls on August 4. Buses run about 45 minutes from Hakone-Yumoto Station to the Kojiri stop (or 40 minutes to Togendai plus a 10-minute walk), and while a 200-space lot exists (1,000 yen per visit, partly free), the mountain roads argue for the bus at night.

Info for International Visitors

Best arrival time

Plan to be at the lakeside 30–45 minutes before the start. Kojiri is one of the harder-to-reach corners of Hakone, so plan your return trip — including bus frequency — before you go.

With kids

The lakeside tucked in the mountains is hard to see underfoot at night, so bright clothing and a small light help. Keep children away from the water and stay attentive.

Photography tips

Play up the echo of light and sound among the mountains: a composition that includes the mountain silhouettes says Kojiri. The bay is small and the launch point close, so a wide angle serves you well.

Payment

Viewing is free. Parking offers 200 spaces (1,000 yen per visit, some free). Food stalls are set up too, but they generally take cash, so bring coins.
