There’s a secret firefly viewing spot in the foothills of the Hoshida mountains. Known only to a few locals who venture out at dusk on humid June evenings, the hidden stream is one of the last untouched areas of Osaka Prefecture and a holdover to the bygone days when lightning bugs were once a common occurrence around the many streams that trickle down from Japan’s mountains. My second venture into the Hoshida range involves crossing this stream and following a dilapidated concrete road to a secluded reservoir ablaze in autumn color. I stare at the terrain and eventually spy what I am looking for: a narrow gap in the chain link fence leading to an even narrower path flanking the eastern edge of the pond.
This pond deserves further attention, for not only does it double as a reservoir for the residents living downstream, but it also serves as evidence that more than just modern mountaineers have been lured by the attractive appeal of the Hoshida region. Construction on the pond began in the early Taisho era, and during excavation work, fragments of pottery were discovered which date from the middle Jomon era roughly 4000 years ago. This caused a halt in construction work and further excavations that revealed dugout foundations suggesting that the early pioneers settled in these very hills. Today all that remains is a concrete marker commemorating the discovery, with the fragments relegated to the Osaka history museum and all else lost in the murk of the pond.
After absorbing the weight of this historical discovery, I duck under the fence and skirt the edge of an impressive escarpment before a gentle descent to reach the foot of nasubi-ishi no tani, or valley of the eggplant stone. The constricted gorge lies littered with toppled trees but a clear path is marked in tape and spends the first few minutes crisscrossing the stream until finally settling on the left river bank along the remnants of a proper path that has fallen into heavy disuse. In summer this must truly be a rat’s nest of overgrowth, but the cooler late autumn temperatures have transformed most of the weeds into a more manageable maze.
Bits of broken concrete appear beneath the moss, the remnants of a walkway that once chauffeured visitors up to the base of the falls. At a recently cleared section of bamboo grass, a stone grave sits precariously on the river bank. The kanji characters engraved in the face are too faded to make out clearly, but the engraving on the back side dates from 1946, so perhaps it was erected to commemorate a fallen war victim. Just behind the monument a fern-smothered stone wall shores up the hillside, possibly doubling as the foundation of a structure lost to time and the elements.
The path soon splits, with an impossibly steep trail forging straight ahead up a 50-degree slope towards the ridge, but it’s the trail branching off to the right that piques my interest. I turn here, grasping the fixed ropes on a dodgy traverse teetering on the edge of a dizzying drop to the stream below until reaching the base of eggplant rock waterfall. The water trickles over the top of the house-sized boulder, which, according to a map from the Edo era, resembles an eggplant due to the black fissures in the stone. These cracks are now lathered in moss and a verdant grove of ferns, feeling like they belong in the jungles of Iriomote rather than the hills of Hoshida. In a wet grotto near the base sits a weathered and somewhat abstract representation of Amida Nyorai, donning a red bib with the inscription Namu Amida Mutsu. The falls were once the mainstay of Shugendō practitioners, perhaps of the Tendai sect which might help to explain the Pure Land undertones. To further complicate matters, the waterfall also go by the name of Hijiri Taki, or Saint Falls, as evidenced by the white prayer tablet placed there by a member of the Japanese Red Cross Society.
Rather than renegotiating that narrow traverse back to the main track, I spy an easier crossing that connects to the narrow north-south spur. At the spur junction, an easier path skirts the eastern face but I head straight up the spine, hoisting myself up to the summit of ⑩ Mt Kōbōkyū (広望丘), which affords my first vistas of the day. I look down upon the valley I have just climbed, tracing the route through a gap in the trees back to the reservoir dam. A steel plate in the shape of a rugby ball has been affixed adjacent to the signpost, with a wooden mallet dangling below. I grasp the gavel and let it fly, sending a reverberating ring deep into the valley below.
As quickly as the trail reaches the summit, it descend to a saddle to the north and a junction to the uppermost reaches of the eggplant gorge. I forgo this route in favor of the ridge, which wastes no time in gaining altitude with a most-welcome addition of fixed ropes. Once again I hoist myself skyward like a sailor stepping the mast, taking care on the slippery sandstone scree where certain death awaits anyone who loses purchase on the tricky terrain. At the top of the spine the angle eases, coaxing me gently to the broad summit of ⑪ Mt Jigokudani (地獄谷山) or hell valley, which is certainly where you would end up if you stumbled off the eastern face. A grove of Mizuhara oak add a cheerful tinge of orange to the otherwise nondescript plateau.
I settle down for a bit of a snack, when the sound of a bear bell approaches. An elderly man in a brown ball cap lets out a jovial greeting, my first such encounter of a fellow hiker in the Hoshida range. After exchanging pleasantries, the white-haired hiker continues down the ridge I had just come up: I offer a cautionary word but he shrugs it off, obviously comfortable in this type of terrain. It never fails to amaze me the tenacity and vigor of Japan’s elderly. Most adults in other parts of the globe would be most content with a book and some knitting or a gentle game of bridge.
The track soon joins the main ridge of the Hoshida mountains: if I head left I can reconnect with the peaks from Chapter 1 of my saga, but instead I veer westward, down a series of rubber-coated wooden steps that double as a path for maintenance workers for the electrical pylons strung through the range. This leads me once again to the stream flowing towards the eggplant falls, where a metal bridge over the water teeters precariously on the brink of collapse, mostly likely caused by the 2018 Osaka earthquake. I somehow make it across the canted structure and head along the edge of a golf course and up to the opposite ridge along a path completely missing from my map. This 60-mountain challenge will certainly involve figuring out pieces of this geographical jigsaw puzzle.
A faint trail leads along a narrow spur for a short shuffle to ⑫ Mt Waribayashi (割林山) which translates as broken woods. This certainly lives up to its name as I keep to the ridge and over a series of toppled trees to reach a dead-end precipice. Scanning the forest for signs of safe passage, I can just make out a bit of blue among the ocherous foliage as I scuttle down to a saddle and scramble up to a parallel spur where the track continues to ⑬ Mt Nasubi-ishi (茄子石山) which sits directly above the waterfall of the same name, the very one I stood admiring just one hour prior. All seems quiet and forgotten up in these hills, like a left-behind item in the corner of an under-frequented boutique.
I turn around and follow the incredibly narrow spur back towards the mountains until confronted with a near-vertical headwall. If I ever meet the guardian angel who installed the fixed rope I will gladly buy them lunch, for without such climbing aids it would have been an exercise in futility. The footing here on the sandstone scree is once again of dubious quality and at several points in the ascent my life lays in the hands of the quality of the rope. I really don’t like putting all of my weight on these things, but with nothing else to grab I leave it up to fate.
The sigh of relief expelled from my battered body could surely be felt by anyone within a several kilometer radius had anyone bothered to be up here at such a late hour in the afternoon. Just fifty horizontal meters from this most unfitting of trail junctions lies one of the only mountains in the Hoshida range that affords a 270-degree view. With this in mind I propel myself to the top of ⑭ Mt Ichigaikaburi-no-se (一蓋被ノ嶺) and take in the stellar views out towards Kyoto. This peak is a favorite for locals wanting to experience the night view, but with no easy way of accessing the peak it would truly take some dedication to make it up here after dark.
With the bulk of today’s climb now behind me, I retrace my steps back to the depilated bridge near the start of eggplant valley and follow a path downstream to the incredibly shy Godan Falls. I can hear the water splashing down from a rock formation but the view is smothered by toppled trees, leaf litter and other debris. Perhaps I should bring my hacksaw next time and do a bit of DIY trail maintenance. Robbed of a view of the waterfall, I keep to the right bank of the stream and soon rejoin the spur at the start of the fixed ropes below Mt Jigokudani. This time I skip the steep re-climb of Kōbōkyū in favor of the side traverse. These paths, called makimichi in Japanese, can be found on most ridge walks in Japan, for they offer an easier and lazier option for those who do not want to follow the undulating contours of the true ridge.
This shortcut trail soon terminates on the true ridge and I am forced to do the hard work on the surprisingly jagged spur. The path leads me up and over Densenoka (電閃丘). Despite being a proper peak, this summit does not feature in the Hoshida 60, probably because the pioneer who named this lookout point succumbed to a lightning strike if the literal meaning of the name is to be taken. The route takes me up and over an additional two unnamed peaks, each offering pleasant enough views before depositing me on the top of ⑮ Mt Asahi (旭山) and the unobstructed vistas to the east for the rising sun. It seems like a tempting place to view the first sunrise of 2021 if not for the lack of space. As I stand on the summit, a lone hiker climbs from below, continuing on the spur to lord knows where. With less than an hour of daylight left I hope he is at least carrying some form of illumination and is not relying on an electrical storm.
The path from Asahi shoots down the western face to soon reconnect with the road just below the reservoir, hearby completing the loop and rounding out another 6 mountains off the once formidable list.
A valley of fireflies (well, maybe a small one) in Osaka-fu. Who would have suspected it. Truly this is a voyage of discovery …
