hiking the Kumano Kodo Nakahechi imperial route

The Kumano Kodo is a network of paths of pilgrimage towards places seen as sacred by either buddhists or shintoists (or syncretists!) from the 700’s. (The Kumano Hongu Taisha shrine celebrated its 2050th anniversary last year!) Meaning for non-believers a well-established system of ancient hiking paths in the mountainous forests of the Kii peninsula, south of Osaka, Kyoto and Nara. Apart from the potential dangers of heavy rain, like massive mudslides, there is no particular difficulty in the hikes (which were done wearing braided straw shoes, the waraji sandals) and a dense network of guest-houses and bus routes makes it possible to adapt the length of the day trips to one’s speed. While this is the place of Japan with the maximum of rain, the hot temperatures actually make it more than bearable when it is a shower and not a typhoon!day one

14km, from Takijiri-oji to Chikatsuyu-Oui, 7:30 hours, 1100 positive gain, nice trail all the way, maximum temperature 32°, met two dozen hikers and two trail runners, got tired by the end, confused one minshuku guest house for another, the hosts of the first one drove us to the second and later brought me back my sandals I have left in their car, no English speaking at the second place and no Onsen but very nice bento box and a pleasant conversation with a couple of Ausso-Danish young women spending a month in Japan and four on the trail. Entire path under cover, making high heat so much more bearable! Not too much in terms of views despite following ridges and visiting tops. Plenty of huge butterflies.

day two

6km, from Doguyaba-bashi (reached by bus) back to Tsugizakura, 2:30-3:00 hours, maximum temperature 30⁰, mixed trail and road, rain spells and showers, met three other couples of hikers, arrived too early at the guest house, waited in a one-room thatched traditional tea house by the side of the road with free hōji-cha tea offered by a very nice old man (not English speaking, alas, which limited the exchanges), reached the guest house at the same time as a Canadian-Spanish couple embarked on a massive six month travel. The dinner was imperial with a whooping ten dishes, all delicate and beautiful. Plus getting our names in Japanese Kanji characters.

day three

9km, from Doguyaba-bashi (the host gave us a ride) to Hosshinmon-oji, 4 hours, 600 positive gain, maximum temperature 29⁰, heavier rain spells, first part really nice then switching to forest track due to closures, finishing detour on tar road, took the infrequent bus to Yunomine-Onsen due to the closure. A few more couples and lone hikers passed us. Stayed at a larger guest-house minshuku with its own natural onsen plus normally access to the river with swimming waterholes. Far from Hongu and Yunomine, alas. But also welcome place to wait two days for the typhoon Krosa to pass by Western Japan.


day four

14km, from Nachisan to Koguchi, 930 positive gain and 1260 negative gain!, alas cancelled as advised by local tourist office due to uncertainties on the state of the trail, took the bus instead and enjoyed a swim after a very hot day in the now quiet Kumanogawachonichi, next to a most congenial guesthouse. Very quiet place, superlative food!


day five

13km, from Koguchi to Ukegawa,  690 positive gain, 5:30 hours, maximal temperature 29⁰, sunny, very enjoyable part of the trail with many ridge walks, no road share, hardly any trace of the typhoon, and early arrival in Hongu. Met with a guest from the Yunomine-Onsen guest house hiking the other way. And very few others.

off to Osaka

Posted in Mountains, pictures, Travel, University life with tags , , , , , , , , , , , , on August 3, 2019 by xi'an

Today, I am off to Japan to visit Kengo Kamatani at Osaka University (where I will give a seminar on Tuesday) for a week and then for two weeks of vacation hiking the Kumano Kodō, a network of ancient pilgrimage routes in the Kii peninsula, south of Osaka. (Presumably with little access to the Internet or even to my laptop!)

Philosophenweg (im Toronto)

IMG_1996Apart from walking the philosopher’s way (or path) in Toronto, after Heidelberg and Kyoto, I had a very enjoyable time (if not weather) for my very first time visit to the University of Toronto, from discussions with several friends of old, to a well-attended seminar, to a grilled octopus lunch in an faculty club and a (French) dinner au Paradis, to seeing a variety of costumes parading the streets for Halloween, with different varieties at six p.m. and two a.m., and to a discovery run in the early and windy Friday morning in the streets of Toronto.

Structure and uncertainty, Bristol, Sept. 25

Posted in pictures, Running, Statistics, Travel, Uncategorized, University life with tags , , , , , , , , , on September 26, 2012 by xi'an

This was a fairly full day at the Structure and uncertainty modelling, inference and computation in complex stochastic systems workshop! After a good one hour run around the Clifton Down, the morning was organised around likelihood-free methods, mostly ABC, plus Arnaud Doucet’s study of methods based on unbiased estimators of the likelihood (à la Beaumont, with the novelty of assessing the inefficiency due to the estimation, really fascinating..). The afternoon was dedicated to graphical models. Nicolas Chopin gave an updated version of his Kyoto talk on EP-ABC where he resorted to composite likelihoods for hidden Markov models, (I then wondered about the parameterisation and the tolerance determination for this algorithm.) Oliver Ratman presented some of the work he did on the flu while in Duke, then move to a new approach for ABC tolerance based on various kinds of testing (which I found clearer than in Kyoto, maybe because I was not jet-lagged!) And I gave my talk on ABC-EL.I found the afternoon session harder to follow, mostly because I always have trouble understanding the motivations and the notations used on these models, albeit fascinating. I remained intrigued by the bidirectional dependence arrow in those graphs for the whole afternoon (even though I think I get it now!) After looking at the few posters presented this afternoon, I went for another short run in Leigh Woods, before joining a group of friends for an Indian dinner at the Brunel Raj. A very full day…!

Structure and uncertainty, Bristol, Sept. 24-27

I am back in Bristol just a few months after an earlier SuSTain workshop. (During my Spring UK trip to Bristol, Glasgow, and Edinburgh…) The theme of the workshop is Structure and uncertainty modelling, inference and computation in complex stochastic systems. And it enjoys a very rich program over the four days! I am talking about ABC and empirical likelihood, with the following slides I just completed:

Unsurprisingly, those slides borrow both from my earlier talks in Kyoto and Australia, and from Pierre Purdlo’s earlier talk on this paper… (I also added pictures of some of the hikes and climbs Peter Green and I survived together!)

I alas arrived too late for today’s sessions, having to give the opening lecture at my Statistics Master in Paris-Dauphine. (I will also alas miss half of Thursday’s talks!) As I am staying at the Avon Gorge Hotel, just next to the bridge, I took the opportunity of some remaining daylight to go running across Brunel’s bridge and into the nearby park of Leigh Woods. It happened to be very muddy thanks to the torrential rains of the morning, but it was a good way to test my recovering knee (after a minor bike fall last week!) on a long run… And it apparently held, although tomorrow morning run will tell for sure.
