Puncture repair in Japan

If you have a puncture on your bike there are plenty of guides out there explaining how to fix the puncture. If using Google is beyond you try this guide from the BBC, or this YouTube video.

Here are some extra notes which are specific to repairing a puncture in Japan. The situation is slightly different over there as most of the bikes have a different type of valve. It is known as a Dunlop, English, or Woods valve. You can read a bit about them here, and there is a photo of one here. Here’s a photo of the English valve with the plastic cap on.

And here is one with the valve removed.

Here are the parts of the valve disassembled.

You can buy a spanner (to unlock the nut which holds the valve in place), and a puncture repair kit from most 100 yen shops. The puncture repair kits work fine despite being very cheap.

What I wouldn’t recommend is a bike pump from the 100 yen shop. They are really, really bad. And will make it much harder for you to pump up the tyre. Buy a proper pump from a bike shop.

Here is the 100 yen bike pump attached to the wheel. Both the bike pumps I got from the 100 yen shop sprung leaks after a few minutes of use. And the plastic of the red one cracked after attempting to blow up the tyre. It is technically possible to inflate a tyre with one of these pumps – I just wouldn’t recommend it!

This is what happened to that cheap bike pump after attempting to inflate the tyre for about 10 minutes.

I came to my senses and bought a better bike pump. This time costing me ¥2940 from a sports shop in a local Youme Town shopping centre. The photo on the left shows the pump and the clip. The one on the right shows how the clip for the English/Dunlop/Woods value attaches to the pump.

This is a bit of an odd system for attaching a pump. Instead of screwing onto the valve, the clip squeezes the pump onto the valve. It works though. You get an airtight connection as long as you don’t alter the angle of the pump too much.

And using one of these you’ll find the tyre much, much easier to inflate. I’ve estimate that you’ll be able to inflate the tyre 20-30 times faster than with the 100 yen pump.
