Tokyo pollen season when you've never had hay fever

Spring pollen can affect more than time outdoors: it also changes where you dry clothes and bedding. Check the apartment's indoor drying options, follow local pollen information, and ask a pharmacist or clinician about symptoms rather than guessing from the season.

If your Tokyo stay falls in spring, check the apartment's indoor laundry options before arrival. Cedar and cypress pollen can make outdoor drying less appealing just when you'd otherwise use the balcony, so a bathroom dryer or a usable indoor airer is worth asking about.

If itchy eyes or sneezing develop, a pharmacist or clinician can help you work out the cause and choose suitable treatment. The season alone doesn't establish that it's hay fever.

Cedar and cypress can overlap

Tokyo's pollen information page describes cedar, スギ (sugi), and cypress, ヒノキ (hinoki), as important spring pollens. Cypress follows cedar, so the end of one tree's main season doesn't necessarily mean the end of symptoms for someone sensitive to both.

Check the current local pollen information for the dates of your stay. Timing and quantities vary, so an uneventful previous visit or a friend's bad spring doesn't predict your own experience.

If you already have a diagnosed allergy, discuss the trip with your clinician or pharmacist before departure. Keep a note of your usual medicine's active ingredient and any treatments that haven't suited you.

Ask about new or troublesome symptoms

花粉症 (kafunshō) is the Japanese word for pollen allergy. The Environment Ministry's pollen manual discusses symptoms and treatment, including seeking appropriate medical care.

At a pharmacy, describe when symptoms began, what they are, and any medicines or conditions you already have. Ask whether a pharmacist is available and whether you should see a clinician. Tell them if the medicine is for a child, if you are pregnant or breastfeeding, or if drowsiness would affect driving or work.

Don't choose a product only because the brand looks familiar. Check the ingredients, age restrictions, warnings and dosing instructions with the pharmacist. If you need a clinic, the clinic visit guide explains how to find one and prepare the medical history.

If symptoms are severe, unusual or affecting breathing, seek medical help promptly rather than continuing to try different over-the-counter products. You don't need to wait for a particular number of days to ask for advice.

Keep an indoor drying option available

The Environment Ministry's manual recommends avoiding outdoor drying of laundry and futons to reduce pollen brought indoors.

Ask whether the bathroom has a clothes-drying function and a suitable rail. A panel marked 換気 (kanki, ventilation) alone doesn't establish that it can dry a load of clothes. Look for the actual model instructions and ask about capacity and operating settings.

The washing machine's own drying label also needs checking. Panasonic explains that its top-loading air-dry functions use no heater: they can dry suitable wholly synthetic clothes, but cannot fully dry cotton or mixed fabrics in the same way. If your wardrobe is mainly cotton, an air-dry button doesn't remove the need for indoor hanging space or another suitable dryer. Ask for the washer model and a photograph of the available indoor drying area before treating a listing's “drying function” as the answer to pollen-season laundry.

If there's only an indoor airer, check where it can stand with suitable airflow and without obstructing doors. Plan loads around that space rather than filling the washer to its maximum every time. Check thick seams and towels before putting them away.

A nearby coin laundry is another option for suitable items. Check the garment labels, machine instructions and the shop's current opening hours. Don't assume all bedding can be tumble-dried or that supplied apartment bedding can be taken for outside cleaning without permission.

The laundry guide helps identify the controls and compare these choices. Confirming the drying method before booking can save an awkward first week with wet clothes in the only working space.

Ventilate while limiting what comes in

Pollen precautions don't mean permanently shutting off the apartment's ventilation. Follow the building's instructions and ask how its system should operate during pollen season.

The Environment Ministry's manual describes reducing window openings and using curtains to limit pollen entry during ventilation. It also discusses removing pollen from clothing and cleaning indoors. Use those measures alongside the room's needs rather than leaving every window wide open for a fixed period.

Keep outside clothing away from clean bedding where practical, and clean using methods suitable for the surfaces. If the room also feels damp, use the humidity guide to check the equipment. Cooling, dehumidification and ventilation are different functions; ask the rental company if the controls are unclear.

Check medicine import rules before packing

If you bring your usual treatment, check the actual ingredients and quantity against Japan's import requirements. Combination allergy and cold products deserve particular attention because one brand can contain several ingredients or different formulations in different countries.

Keep the labelled packaging and prescription information where relevant. Even if you can buy your medicine without a prescription at home, check whether you can bring its ingredients and the amount you need into Japan.
