A cold planet ... a Zombie planet!

Ikaho is a hot spring resort in the mountains Northwest of Tokyo, about an hour and a half from Tokyo by bullet train and local train and bus. It is famous for being the historical summer home of emperor’s, and also for having a huge flight of stone stairs that runs from the bottom of town to the top. This flight of stairs is lined with shops, and at the top is the source of the town’s hot spring water. I’ve been told that even today, hot spring water is allocated from this source in strict accordance with the degree of nobility of the recipient’s heritage, though I don’t know whether that’s true or not. The town is essentially a resort town, with no other business to be found except tourism. It’s also slowly crumbling, as are many rural towns in Japan, as the population ages and the young people leave for the cities. A good proportion of the buildings in this town, that used to hold thriving businesses, are now derelict. In fact, you can’t see it from the second rate photo I took from my second-rate hotel room, but in front of my ageing hotel there was a wide patch of scrub grass on a slope, essentially untended and growing very tall, in amongst which a few crumbling sheds were being slowly reclaimed by nature. A room with a view indeed … However, Ikaho’s fading charms aside, it does make quite an excellent mountain fastness from which to weather the zombiepocalypse.

Review

Defensibility: Although Ikaho is accessible from several locations, much of the town consists of multi-storey buildings on slopes accessible only through a single road or steps. In some cases (such as my hotel) the area in front of the buildings is open space, and some of these buildings may have an exit to the hillside that is above the entrance (e.g., my hotel had an emergency exit on a higher level than the main entrance, and the exit emerged from the opposite side of the hotel). In other cases, buildings may be quite isolated from the rest of the town and surrounded by quite thick forest. This makes them potentially quite defensible (Japanese forest at its thickest is impenetrable for people). At the top of the town is a long flight of steps, perhaps 200 m long, lined with small souvenir shops and restaurants. These steps are joined at regular intervals by narrow side streets, but these side streets would be easy to block. At the top of the steps is a kind of hotel or administrative building, surrounded by walls and a gate, and near that is the source of the hot spring water. By blocking the streets and closing off the buildings one can establish a quite defensible redoubt – live at the base of the steps and, if a zombie horde encroaches, flee up the steps, drawing them into the natural death trap formed by the souvenir shops – then roll rocks down on them, or close off a single barrier and use stakes and spears to destroy them. In this sense the town is defensible in quite a low-tech way.

Escape routes: In addition to the obvious ways in and out of the town, at the very top of the steps after a short run one can reach a river in a kind of canyon, that is crossed by two small bridges. If one were to park a car on these bridges they would become essentially uncrossable, but there is a road on the far side that – I guess – leads out of town through a little-used route. This gives a good escape route from the town, assuming a zombie horde came from the lower reaches (i.e. closer to the nearest towns) and not from the mountains. By establishing a small car pool on the far side of this bridge and preparing mobile barriers for the bridge itself (or, better still, a means of knocking the bridges down) one would have a fairly reliable escape option. As far as I can tell the only other way across this canyon is through the riverbed, but like most rivers in Japan it is concrete-lined and hard to scale. Ikaho also features a rope way leading up to a mountain top, so another option could be to establish a flying fox mechanism from their back into town – then, lead the zombies up the mountainside, and when you get to the top use the flying fox to rapidly get back down the hillside, leaving them lost and confused on the mountainside.

Location: Ikaho is located far from Tokyo, but it is not in as secluded a location as Hakone. It is a short bus ride from the town of Shibukawa, a typical sprawling (by Japanese standards) rural supply town. The most likely approach will be through Shibukawa, with a stop to get urgent supplies; this would be dangerous. There are bypasses which take the intrepid survivor group through smaller country towns, and this is the best bet if one wants to guarantee rapid and safe access to Ikaho. Ikaho’s slight remove from Shibukawa is useful though, because it gives survivors the option of raiding Shibukawa’s shopping centres (“doing a run” as they say in The Walking Dead) for essentials. Looking at the map of the area, I notice that there are quite a few golf courses nearby, which at least provide a wide range of clubbing weapons and possibly a clubhouse to raid for supplies. However, the nearness to Shibukawa and the main roads running north from Tokyo means that Ikaho may be a target for random zombie encounters and/or hordes. Remoteness is a useful property in a survival location.

Concealment: Like Hakone, Ikaho is largely invisible from the larger towns, so zombies won’t congregate on its distant lights or the sounds of habitation here – it will only draw zombies who are already just wandering through the mountains aimlessly. Assuming zombies radiate outward from Shibukawa randomly once they’ve eaten all its residents, it is likely that they will mostly miss Ikaho and wander into the wilderness. Establishing a solid barrier at a suitable juncture – such as in front of the visitor’s centre at the edge of town – might cause them to turn down a different road leading away from the area long before they receive any indication that there are humans in the town. Thus even small hordes would be less likely to approach the town, and defending it would likely consist of keeping an eye out for occasional lone wandering zombies. Unfortunately, these zombies will still have many places to hide and cause trouble – the crumbling buildings and scrubland make it easy for a zombie to be missed even from the best vantage points in town, so patrols might be necessary in order to ensure the town’s safety.

Sustainability: As a remote tourist town, Ikaho boasts a lot of restaurants and a small resident population. It’s likely that in the short term there would be a large stock of fresh and preserved foods to consume while preparing defenses. It’s worth noting here that tourist towns in Japan contain a lot of souvenir shops selling food, and much of this food is preserved food – dried and pickled fish are very popular souvenirs, as are low-sugar sweets (dumplings and cakes) that are designed to last for up to a month after purchase. So upon arrival, the group could establish a simple consumption order: first the fresh food that can spoil, while the fridges are still running; then the frozen goods once the electricity dies; then move onto the preserved foods. Potentially in a place like Ikaho one would have as long as a month to establish a mechanism for sustainable food supplies, and maybe even longer. There would likely be huge stocks of rice on hand, and these would be easy to cook – one can establish a steaming mechanism using the onsen (hot spring) water from the top of the hill, and in fact there is a little restaurant at the top of the town which serves eggs boiled in onsen water, so the mechanism has already been established.

Most importantly though, Ikaho comes with a supply of fresh meat and a potential farming area pre-prepared. Near the bottom of the town is a tourist ranch, holding cows and sheep and goats, that will likely still be functioning if the survivors arrive fast enough. In addition to holding the animals, the ranch is intended as an educational enterprise so likely contains basic information on how to milk and herd them. If the ranch staff are still there they could even be convinced to participate in establishing the long-term survival of the community. The nearby golf-courses can be converted into rice paddies, as probably could the stepped slopes of the town itself, and there is ample scrubland for planting potatoes and vegetables. Just a short drive away from the town is Haruna lake, which in addition to a source of fresh water for the town (through the aforementioned stream) also probably contains fish. Haruna lake is unlikely to be thronged with zombies, being even more remote than Ikaho, so a pair of people visiting the lake could fish for the group with relative impunity.

Ikaho’s main sustainability problem is its lack of fuel and distance to the local town, but this could be easily solved by bringing a large number of bicycles, and using them to move to and from Haruna lake. Then fuel can be conserved for visits to the town of Shibukawa – and that fuel need only be used for the drive back, since cars could coast to the town. With such mechanisms in place it is likely that Ikaho could provide a good long-term survival spot from which to weather a few seasons of the zombiepocalypse.

Natural hazards: The main risks to life in Ikaho are the possibility of collapsing buildings, forest fires and of course the ever-present risk of rock falls and landslides. Ikaho is far removed from the centre of Japan’s typhoon zone and unlikely to flood, but one problem it does have is winter. Being north of Tokyo and in the mountains, it will have a long, harsh winter. Even in early April when I visited there was no sign of a single new leaf on even one tree – it was barren as far as the eye could see. With potentially 6 months where nothing grows, winters will be harsh if one does not arrive with a very large stock of rice and tinned goods. The local stocks of rice – particularly in the hotels – would likely last a whole season, but the work in the next summer to secure sufficient rice and potatoes for a second winter could be hard. Staying warm in winter would not necessarily be a challenge – in addition to the ample local wood supplies, the onsen water could be used to warm houses, or one could just sit out the winters in an onsen. Winters of this severity also offer the opportunity for a respite from zombie incursion, as zombies will likely freeze, and this gives the residents potentially a three month period in which to work freely on establishing defenses, preparing the ranch, and so on. Winters after the first could be lean times, but provided some farms could be established in the first year, they will be survivable.

Tactics

In fleeing to the countryside one should remember that Japanese rural towns all have many automatic rice-dispensing facilities, which can carry hundreds of kgs of rice. Before the electricity runs out these will be easy to use – take a large supply of money and sacks, and just feed the money in! One great thing about vending machines is that they can’t profiteer, so while the rice sellers in town will soon be hiking up their prices, unless the companies are very organized and somehow immune to the general societal collapse, these rice hoppers will continue to sell rice at peacetime prices. Money isn’t going to be relevant, but a good supply of rice is going to be priceless. If one wants to survive long-term in Japan after the zombiepocalypse, the first thing one should grab is a very very large stash of sacks. Every hopper you come to, loot for everything its got. Then you have both a barter good for dealing with people you meet, and a source of long-term survival that, if treated carefully, may last more than a year.

Ikaho’s defenses are not so intuitive as in Takao, so to prepare a proper defense of the town – with its winding streets and multiple possibly inter-connected crumbling buildings – would require poring over a map, establishing choke points and defensive layers, and preparing fall back positions. It’s probably also not such a good place for a very small group of survivors – I would guess that with less than 20 people in your group you won’t be able to set up the required defensive positions quickly. Upon arrival the best idea is probably to establish a redoubt at the top of the stairs, and to fan out from there securing the rest of the town once the group has its first base intact. Because it’s a tourist town, it’s easy to pick up maps and guides when one arrives, and the town is self-contained and small enough for new arrivals to quickly get a sense of all its ways and byways. Starting from a small base, one could slowly secure the town and establish defensive rings and tactics.

Conclusion

Ikaho is not as defensible as Takao but offers better long-term sustainability options, and is further removed from the hordes of Tokyo. With its local ranch and nearby golf courses, as well as a nearby fishing lake, it offers both short term and long term food supplies, and the presence of a strong and reliable local onsen source reduces the need for electric power for cooking and heating. Provided that some degree of farming can be established within a year and mechanisms put in place for weathering the worst of winter, it may be an ideal spot to weather the initial storm of the zombiepocalypse, and a good base from which to reclaim at least a small part of the world for human habitation.
