The difference that runs through everything

A home is occupied. A second home is not, for most of the year, and Japanese systems treat those two situations differently at almost every point.

Insurance classification. Tax correspondence. Building deterioration. Neighbours. Local authority attitude. Each is covered elsewhere on this site, and each has a specific second-home version.

Insurance is where the second-home distinction pays

Japanese fire insurance classifies buildings by use, and a house with nobody living in it is generally placed with shops and offices rather than homes. That class generally cannot carry earthquake cover.

A second home in genuine periodic use can sit in the residential class, with earthquake cover available. That is a material difference, and it is the strongest single argument for maintaining the property properly rather than letting it drift.

What sustains it is the use being real: furniture and bedding in place, utilities connected, the house habitable on arrival, and visits actually happening. Records of visits document that. They do not create it, and nobody should suggest otherwise.

Where a second home quietly stops being used, the classification stops matching and the duty to notify the insurer arises. A property that changed in practice without changing on paper is a policy that may not respond.

Resort areas have costs that urban property does not

Mountain and coastal resort districts frequently run on infrastructure that is not municipal.

Ask specifically about the access road. A private road with no clear maintenance arrangement is a dispute waiting for the winter it fails, and if it is not a road in the legal sense, the rebuild question arises as well.

One cost is specific to Kyoto. The city has legislated a tax on homes in its urbanised area where nobody is resident, and second homes are expressly within it. Collection is scheduled to begin in fiscal 2029, and the city indicates it will often come to around half of the property's fixed asset tax. If Kyoto is on your list, it belongs in the running costs.

The building deteriorates on the empty-house schedule

Everything in the vacant-property guides applies to a second home between visits, at the same pace.

The water in the drain traps evaporates, and the smell that greets you on arrival is the first of three stages. Damp accumulates and mould spreads in a closed-up house with no air movement. A leak that starts in March is found in September, by which time it has been running for six months.

Four visits a year means four chances to notice something, at intervals of three months. That is the interval in which problems develop into expensive problems.

And typhoon damage does not wait for your next visit. Nor does a wall or a tree falling on somebody.

The neighbours, and why they matter more here

In a resort district your neighbours are frequently the only people who see the property. They notice the broken window, the fallen branch, the car parked outside that should not be.

The question is whether they can reach anybody. If they cannot, their options are to contact the local authority or to give up, and contact with the authority accumulates as a record.

Rural and resort communities also have expectations: shared maintenance days, association dues, rotas for clearing common areas. An owner who never participates and cannot be contacted is a known category, and it is not a good one to be in.

Letting it when you are not there

Many second-home buyers plan to let the property between visits, and the plan is often assumed rather than checked.

Short-term letting is capped at 180 nights under the accessible route, restricted further by local ordinance in many areas, and prohibited outright by the management rules of a great many apartment buildings. In resort areas the local restrictions are often tighter rather than looser, because the resident population has views about it.

And rent paid to a non-resident owner can be subject to withholding at source, which changes the arithmetic.

Check whether letting is permitted at that address before you buy, not after. It is a free question and it is decided by things you cannot change.

What to establish before you offer

1. Will the property be in genuine periodic use, and will that sustain a residential insurance classification?
2. Water and drainage: public or private, and what does the private version cost annually?
3. The access road: public or private, who maintains it, and who clears snow?
4. Is there a development association, and what are the fees and obligations?
5. What is the area like out of season, and what closes?
6. Is short-term letting permitted here, under the zoning, the local ordinance and any management rules?
7. Who will maintain the property between visits, and at what cost?
8. Have you seen it in winter?

Question seven belongs in the purchase budget rather than in a later conversation. It is the cost that makes every other cost on this page smaller, and it is the one most often left out of the sums entirely.

It is a good thing to own

None of the above is an argument against a Japanese second home. The reasons people want one are real, and Japan is unusually good at the things that make one worth having.

The argument is narrower. A second home is empty for around ninety-three per cent of its life, and the purchase decision should be made on the basis of that number rather than on the basis of the four weeks you will be there. Get the maintenance arrangement right and everything else on this page becomes routine.
