First Trip to Japan (Honshu) in Nov/Dec – Advice on Target Species & Itinerary

Hi everyone,

I’m planning a 3-week family trip to Japan from mid-November to mid-December. This will be our first time there, so we are focusing exclusively on Honshu (planning for Tokyo, Kyoto, and we’re currently debating whether to include the Japanese Alps).

While we definitely want to experience the classic highlights and the trip won’t revolve entirely around mammal watching, I’m very keen to dedicate quality time to targeted early morning walks or night drives.

My main target species are:

  • Tanuki (Raccoon Dog)

  • Japanese Marten

  • Japanese Badger

  • Japanese Weasel

  • Japanese Giant / Dwarf Flying Squirrel

  • Asiatic Black Bear (though I realize they might be starting to hibernate by late Nov/Dec?)

  • Any other Mustelides

My main questions for the group:

  1. Are the Japanese Alps an absolute MUST to get a high probability of seeing these targets, or is it realistic to spot them closer to the classic “golden route” areas that we will be visiting anyway?

  2. How does our specific timing (mid-Nov to mid-Dec) affect the activity levels and visibility of these mammals?

  3. Local Contacts: Does anyone have recommendations for local guides, researchers, or contacts who can help arrange focused evening/night spotting sessions in Honshu?

Thanks so much in advance for any insights or contacts!

Best, Yuval

    Hi Yuval – in theory you can see the badger, marten, giant flying squirrel and tanuki in Tokyo in a night – check my report from 2025. But I am not sure what your chances are going to be like in the winter. I suspect that those chances will be less in the alps where I think the badgers will probably be hibernating. There are hotels/guest houses in the alps that encourage animals to visit. So if Bergcot is closed or full then there should be other places where the marten and tanuki should be around if you miss them in Tokyo. The only places I know for the dwarg flying squirrel are high in the mountains and likely shut in the winter. I’ve never seen Japanese Weasel but my son saw one at Daisen in Tottori prefecture and was told they are quite common around there. Hope that helps a bit

    I’ve been mammalwatching in Japan only for a few nights in July a couple years ago, but my general impression was that none of the mammals are easy – it’s basically somewhat similar to mammalwatching in central Europe: the animals are there, but outside if specific “tricks” (such as people feeding them near mountain huts), they are rather hard to find. From this entire list I saw only the Raccoon Dog (and some other amimals not on the list).

    All of these species are possible if you do a lot of night driving, but for bear, tanuki and badger I’d focus on lower elevations as they would be much less active or hibernating higher up (as Jon already mentioned).
    As for other mustelids, ermine and least weasel are mostly confined to high elevations on Honshu – your chances of seeing them will depend on the timing of road closures. If the first snowfalls come late you might actually have better-than-usual chances because they’ll turn white and will be easy to spot in alpine meadows.
    There’s plenty of good sites. I wrote a book Finding Mammals in Japan with lots of site tips and other info, you can get a PDF for US$25 – just email me to dinets at gmail 🙂
    P.S. If you plan on travel to the J Alps, make sure your rental car has chains in the trunk – they might be required for some roads.

    I saw an injured Japanese badger in Tottori on a giant salamander tour this summer but I’m not sure how often they’re spotted
